Understand Weight-Loss Plateaus

Weight loss often slows or stops after the first weeks or months, even when you are still following your plan, and this is common rather than a sign that you have failed. This page explains why progress stalls and what realistic responses look like; losing weight in the first place, keeping it off, and the midlife changes in weight each have their own pages.

General information, not medical advice. Last updated October 31, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.

Start here

Give it a few weeks and look at the whole picture before changing anything: your weight trend, your waist, how clothes fit, your energy and your mood, not one day's reading on the scale.
Check your habits honestly for one to two weeks by writing down what you eat and drink and how much you move. Studies show that people often underestimate what they eat and overestimate their activity.
Look after the basics that support any plan: enough sleep, regular activity including some strength work, and enough protein and fibre, rather than cutting food further.

Be careful with

Do not respond to a plateau with crash dieting, skipped meals, laxatives, diuretics, fasting for days, or extreme exercise. These can be harmful, and they tend to increase hunger and the chance of regaining weight.
Fat burners, detox teas and 'metabolism boosters' are not a safe fix. The US FDA warns that many weight-loss products are likely to contain hidden drug ingredients, and herbal products can interact with medicines.
Do not stop or change a prescribed medicine (including diabetes medicines) on your own because of weight. Talk to the prescriber first. If you are pregnant, breastfeeding, under 18, older, or have a history of an eating disorder, get a clinician's guidance before trying to lose weight.

Get help when

Weight that changes without you trying, in either direction, or that goes up quickly together with swelling or breathlessness. Unexplained weight change needs a medical check.
A new medicine, or a health condition such as an underactive thyroid, polycystic ovary syndrome, depression or diabetes, that may be affecting your weight. Ask a doctor or pharmacist to review them.
Fear of eating, strict food rules, bingeing, purging, or feeling unable to stop dieting when the scale stalls. These need professional support, not more restriction.
Feeling dizzy, faint, very tired or low in mood while dieting, or a sense that weight is taking over your thoughts.

About Understand Weight-Loss Plateaus

What this goal means

A weight-loss plateau is a stretch when your weight stops going down, or goes down much more slowly, even though you are still following your plan. This goal is about understanding why that happens and what sensible next steps look like.

It is not about pushing harder. Often a plateau is the body and the plan catching up with each other, and the most useful response is to check, adjust gently and be patient.

^1,2

What it can feel like

Many people describe working just as hard as before but seeing the scale stay put for weeks. It can feel frustrating, unfair or discouraging, and some people are tempted to give up, or to cut food further.

These feelings are understandable and very common. Weight is only one measure of how your body and health are changing.

Why progress can slow or stall

A mathematical model of adult metabolism found that body weight responds slowly to a change in food intake, with half times of about 1 year, and that people with more body fat take longer to reach a new steady weight. It also builds in the fact that energy use adapts during weight loss.

As you get smaller, your body needs fewer calories, so the same eating plan produces a smaller gap than it did at the start. NIDDK says metabolism slows down during weight loss and that hormone changes can make it harder.

A review describes what happens after weight loss: hunger rises, fullness hormones fall, and energy use drops more than the change in body size alone would predict. In one study of 50 adults who lost about 13.5 kg on a very low energy diet, appetite hormones had still not returned to their starting levels a year later and hunger was higher.

Habits can drift too. In a classic study of people who said they could not lose weight on less than 1,200 calories a day, their energy use was normal, but they had under-reported what they ate by about 47% and over-reported their activity by about 51%. That was a small group, and it does not mean everyone with a plateau is miscounting, but it shows why a careful check is worth doing.

^1,2,4,5,6

Other things that can play a part

NIDDK lists sleep, some medicines and some health problems as factors that can affect weight. Not enough sleep is linked to weight gain and may make you hungrier and more likely to choose less healthy foods. Some medicines for epilepsy, depression or psychotic disorders, steroids and some diabetes medicines can contribute to weight gain, and health problems such as polycystic ovary syndrome, Cushing's syndrome, an underactive thyroid, depression and long-term stress can too.

If a plateau comes with other changes, or you have started a new medicine, a clinician can check these possibilities.

⁷

Realistic expectations

NIDDK says experts recommend an initial goal of 5% to 10% of your starting weight within 6 months, and NHS says even a loss of 5 to 10% can improve health. Slowing down after a first steady loss is expected.

The old rule that a 3,500-calorie shortfall equals one pound of weight loss is a rough rule of thumb. Modelling and tests in closely supervised studies show it overestimates weight loss over time, because the body changes as weight comes off.

Success is not only the scale. A plateau can also be a good time to practise keeping your weight steady, which is its own skill.

^3,8,9,10

Who this applies to

Adults who set out to lose weight and whose progress has slowed or stalled. If you have not started yet, see Lose Weight Sustainably; if you are trying to keep weight off, see Maintain Progress Over Time; if weight is changing in midlife, see Manage Weight Changes in Midlife.

If your weight is falling without you trying, that is a different question; see Unintentional weight loss. People with diabetes, pregnancy, an eating-disorder history, or who are under 18 or older adults need clinician guidance before changing their eating.

A manageable starting plan

An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.

Your first actions

Wait and watch for two to four weeks, noting your weight trend, waist, clothes, energy and sleep.
Spend one to two weeks honestly writing down what you eat, drink and do, unless tracking makes you anxious.
Protect your sleep, keep moving most days and include some strength work.
Include a protein food and plenty of vegetables, fruit and whole grains at meals.

Optional additions

Ask a dietitian to review your plan and targets.
Ask your doctor to review your medicines and check for health conditions.
Choose a short, planned period of keeping weight steady, with professional guidance, before another push.
Add non-scale goals such as a walk, a strength session or better sleep.

What to track

Weight trend over several weeks, not daily numbers.
Waist and how clothes fit.
Energy, mood, sleep and hunger.
Any new medicine or supplement.

When to reassess

After four weeks of steady habits, check again. If you have changed nothing and still wish to lose weight, make one small change at a time. If you feel stuck or discouraged, or you notice unexplained changes, book a visit with a doctor or dietitian.

When to seek professional support

See a doctor if weight changes without explanation, or if you take medicines that may affect weight.
Ask for a dietitian or program referral.
If food or weight is taking over your thoughts, contact a doctor or an eating-disorder helpline in your country.

What helps

Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.

Start here

Look at the whole picture, and give it a few weeks

Low certainty

Addresses: Tells you whether you really are on a plateau

Why it may help: Weight responds slowly to a change in intake: in a model of adult metabolism the half time was about 1 year. A flat week or two does not necessarily mean the plan has stopped working. Weight is also only one measure. NHS also uses a waist measurement of more than half your height, alongside BMI, as one reason to see a GP, so waist is a useful second number.

How to apply it: Weigh or measure in the same way at a similar time of day, look at the trend over several weeks, and also note waist, how clothes fit, energy, sleep and mood.

Who it may suit: Anyone who feels stuck.

Precautions: If checking weight or measuring your body makes you anxious, or leads to restricting food, skip it and talk to a clinician.

^1,8

BMI, body composition and muscle →

Check your food and activity honestly for one to two weeks

Low certainty

Addresses: Finds quiet drift in portions, drinks or activity

Why it may help: In a systematic review of 22 studies, self-monitoring of diet, exercise and weighing was consistently linked with weight loss, though the evidence was described as weak because of study limitations. In a small study, people who reported being unable to lose weight were found to be eating about 47% more than they reported.

How to apply it: Write down what you eat and drink, including snacks, drinks and weekends, and how much you move. Use it to notice patterns, not to judge yourself. If you have ever had a difficult relationship with food, skip this step.

Who it may suit: Adults who have been losing weight and then stalled, with no history of disordered eating.

Precautions: Food tracking can feed obsession in people prone to disordered eating. Stop if it makes you anxious.

^11,6

Eating disorders and disordered eating →

Expect the plan to need small adjustments as you get smaller

Moderate certainty

Addresses: Keeps the plan matched to your current body

Why it may help: Your body needs fewer calories at a lower weight, so the same plan creates a smaller gap than before. NIDDK says metabolism slows down during weight loss and the body needs fewer calories at the new, lower weight. A review also describes rising hunger and reduced energy use after weight loss.

How to apply it: Rather than cutting hard, make small, sustainable changes you can keep, and revisit your goals. A registered dietitian can help you adjust safely without going too low.

Who it may suit: Anyone whose weight loss has slowed after weeks or months of progress.

Precautions: Do not cut food to very low levels. Very low intakes can cause tiredness, dizziness and nutrient shortfalls, and they are not a safe response to a plateau.

^2,1,4

Healthy weight basics → Lose Weight Sustainably →

Additional options

Keep up regular activity, and add strength work

Moderate certainty

Addresses: Supports weight loss and keeps muscle

Why it may help: The ACSM position stand says 150 to 250 minutes a week of moderate activity gives only modest weight loss, and more than 250 minutes a week was linked with clinically significant loss, while resistance training does not boost weight loss but may increase lean mass. A review concluded that both endurance and resistance exercise help preserve muscle during weight loss, and that the usual minimum guidelines are generally not enough for clinically significant loss without eating less.

How to apply it: Build up gradually, aim for activity you can keep doing, and include some muscle-strengthening work. See the muscle page for details.

Who it may suit: Most adults who are able to be active.

Precautions: Check with a clinician before starting a new program if you have heart disease, joint problems, are older, or have not exercised for a long time. Avoid exercising to punish yourself for eating.

^12,13,14

Preserve Muscle While Losing Weight →

Make sure you are eating enough protein and fibre

Moderate certainty

Addresses: Keeps you fuller and protects muscle

Why it may help: A meta-analysis of 24 trials (1,063 adults, about 12 weeks on average) found higher-protein diets gave modest extra benefits for weight (about 0.8 kg), fat mass and keeping fat-free mass compared with standard-protein diets. A review of weight maintenance links less hunger and more fullness with higher protein and fibre intake.

How to apply it: Include a protein food at each meal (for example fish, eggs, beans, lentils, tofu, yoghurt or lean meat) and plenty of vegetables, fruit and whole grains. A dietitian can tailor amounts.

Who it may suit: Most adults without kidney disease.

Precautions: People with kidney disease should ask their clinician about protein. Benefits are modest.

^15,4,14

Manage Hunger & Cravings →

Protect your sleep

Low certainty

Addresses: Eases appetite and food choices

Why it may help: NIDDK says not getting enough sleep is linked to weight gain and may make you hungrier. In a randomized trial of 80 adults aged 21 to 40 with overweight who usually slept under 6.5 hours, extending sleep by about 1.2 hours a night lowered energy intake by about 270 kcal a day compared with the control group. That trial did not test people on a plateau.

How to apply it: Aim for a regular schedule and 7 to 9 hours a night for adults aged 18 to 64.

Who it may suit: People who sleep little or poorly.

Precautions: Persistent sleep trouble, loud snoring or gasping at night needs a medical check, as sleep apnea can be linked to weight.

^16,7

Improve Your Sleep Quality → Sleep, stress and the food environment →

Ask a clinician to review your medicines and health

Moderate certainty

Addresses: Finds medical reasons that are making weight harder to lose

Why it may help: NIDDK says your health professional may review medicines and supplements you take to see whether they are affecting your weight or your ability to lose it. Some medicines and health problems, such as an underactive thyroid, can contribute to weight gain.

How to apply it: Book a visit, bring a list of every medicine and supplement, and describe how your weight has changed.

Who it may suit: Anyone who has plateaued despite sticking to a plan, or who has started a new medicine.

Precautions: Never stop or change a prescribed medicine on your own.

^7,3,8

Medicines that can change weight → Thyroid problems and fatigue →

Get support from a dietitian or a structured program

Moderate certainty

Addresses: Personal adjustments and accountability

Why it may help: NIDDK says successful programs offer realistic goals, a healthy lower-calorie eating plan, a physical activity plan, guidance on setting goals and overcoming setbacks, and a plan for keeping the weight off. NHS says a GP can refer you to weight management programmes.

How to apply it: Ask your doctor for a referral to a registered dietitian or an evidence-based program. Use the questions NIDDK suggests for checking a program.

Who it may suit: Anyone who has been stuck for more than a few weeks.

Precautions: Avoid programs promising very fast loss or selling their own supplements.

^3,8

Weight-loss medications and medical care →

Still being studied

Planned breaks from dieting

Low certainty

Addresses: May reduce metabolic slowing and improve loss

Why it may help: In the MATADOR trial, 51 men with obesity were randomized to 16 weeks of continuous calorie restriction or the same amount alternating with two-week blocks of eating to maintain weight. Those in the intermittent group lost more (14.1 versus 9.1 kg in those who completed the study), and their energy use after adjusting for body composition fell less. This is a single small trial in men, and it did not test people already on a plateau.

How to apply it: Not a do-it-yourself recommendation. Ask a dietitian whether a planned maintenance period suits you.

Who it may suit: Under study; adults with obesity under supervision.

Precautions: Not tested in women, people with eating-disorder history, diabetes or older adults. Avoid unplanned 'cheat days' as a substitute.

¹⁷

Eating patterns compared →

Switching to intermittent fasting

Low certainty

Addresses: Probably no better than regular advice

Why it may help: A 2026 Cochrane review of 21 trials (1,430 people) found intermittent fasting may result in little to no difference in weight loss compared with regular dietary advice (low-certainty evidence). It did not study people on plateaus.

How to apply it: Fasting is a personal choice; it is not a proven way to get past a plateau.

Who it may suit: Some adults who find it easier to follow.

Precautions: Not suitable for pregnancy, under 18, eating-disorder history, or people on diabetes medicines without medical guidance.

¹⁸

Eating patterns compared →

Treating the plateau as practice for keeping weight steady

Low certainty

Addresses: Builds the skill of keeping weight steady

Why it may help: Registry data on people who have kept off large losses describe high activity, regular eating patterns and self-monitoring of weight, and that maintenance may get easier after 2 to 5 years. These are observational findings and do not show that a pause causes success.

How to apply it: Treat a plateau as a chance to practise your maintenance habits, and read the maintenance page.

Who it may suit: People who have already lost weight and feel stuck.

Precautions: If your health goal still needs more loss, discuss next steps with a clinician.

¹⁹

Maintain Progress Over Time →

Food & nutrition

There is no single food or pattern that breaks a plateau

NIDDK says that although studies suggest different eating plans may promote weight loss, the best plan is one backed by science and tailored to your health, culture, preferences and values, so you can stick with it. The Cochrane review of intermittent fasting found little to no difference compared with regular dietary advice. No food has been shown to speed through a plateau.

This page gives no calorie targets, because safe levels depend on your age, size, health and medicines. A registered dietitian or clinician can work them out with you.

^3,18

Food habits worth checking

These are everyday habits, not treatments.

A protein food at each meal

Moderate certainty

Addresses: Fullness and keeping muscle

Why it may help: Higher-protein weight-loss diets gave modest extra loss of weight and fat and kept more fat-free mass in a meta-analysis of 24 trials. Reviews describe a modest effect on fullness.

How to apply it: Eggs, fish, beans, lentils, tofu, nuts, yoghurt or lean meat.

Who it may suit: Most adults.

Precautions: Kidney disease and some other conditions need advice about protein. Allergies apply.

^15,20

Appetite, hunger and cravings →

Vegetables, fruit and whole grains

Moderate certainty

Addresses: Bulk, fibre and nutrients with fewer calories

Why it may help: NIDDK, citing the Dietary Guidelines for Americans, describes a healthy eating plan built on vegetables of all types, whole fruits, whole grains and low-fat or fat-free dairy or alternatives. A review links less hunger with more fibre.

How to apply it: Fill half the plate with vegetables, and choose whole fruit rather than juice.

Who it may suit: Most adults.

Precautions: Increase fibre gradually and drink fluids.

^2,4

Hidden calories in drinks, snacks and weekends

Low certainty

Addresses: Closes the gap between what you think you eat and what you eat

Why it may help: People in one study under-reported their food intake by about 47% on average. Drinks and snacks are easy to miss.

How to apply it: Look back over a normal week, including drinks and weekend meals.

Who it may suit: Anyone who suspects drift, unless tracking is risky for them.

Precautions: Skip if you have a history of disordered eating.

^6,11

If food has become stressful

If you feel afraid of eating, follow rigid rules or binge and compensate, please see the page on eating disorders and disordered eating and talk to a clinician.

⁸

Remedies & supplements

Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.

Green tea and green tea extract

Low certainty

Studied form and route: Tea, or extract capsules

Intended outcome: A hoped-for small push on weight

Human evidence: A Cochrane review found no important effect: in six studies outside Japan the weight difference was -0.04 kg. Studies from Japan varied from -0.2 to -3.5 kg and could not be pooled. None of this was tested in people on a plateau.

Limits: Studies were 12 to 13 weeks long and the results are inconsistent.

Interactions and precautions: Concentrated extracts can interact with some medicines, so ask a pharmacist; caffeine content matters in pregnancy.

^21,22

Green tea →

Apple cider vinegar

Low certainty

Studied form and route: Vinegar drink, or capsules and gummies

Intended outcome: A small short-term effect on weight and waist

Human evidence: A 2025 meta-analysis of 10 randomized trials (789 people) found daily apple cider vinegar was associated with lower body weight, BMI and waist, with high variation between studies. Benefits were seen for up to 12 weeks and at 30 mL a day in subgroup analyses (a study amount, not advice). The authors call it a possible short-term add-on.

Limits: High variation between trials, short duration, and not tested for plateaus.

Interactions and precautions: Acidic drinks can irritate the throat and teeth and cause stomach upset. Check with a pharmacist if you take diabetes medicines or diuretics.

²³

Apple cider vinegar →

Berberine

Low certainty

Studied form and route: Capsule supplement

Intended outcome: A small average difference in weight

Human evidence: A 2026 meta-analysis of 23 articles found berberine reduced body weight by about 0.88 kg on average compared with control, and also BMI and waist. The authors said trials need better reporting of purity and amounts and have common biases such as lack of blinding.

Limits: The average difference is small and the quality of products and trials varies.

Interactions and precautions: Berberine can interact with medicines, including diabetes medicines. Ask a pharmacist, and ask a clinician before any use in pregnancy.

²⁴

Berberine →

Chromium

Low certainty

Studied form and route: Chromium picolinate supplement

Intended outcome: A hoped-for effect on weight

Human evidence: A Cochrane review of nine trials (622 people, up to 24 weeks) found a difference of about 1.1 kg after 12 to 16 weeks that the authors described as of debatable clinical relevance, based on low-quality evidence. Only three studies reported side effects, including serious events.

Limits: Short trials, low-quality evidence.

Interactions and precautions: Ask a clinician if you take diabetes or thyroid medicines.

²⁵

Chromium →

Garcinia cambogia

Evidence against

Studied form and route: Capsule supplement

Intended outcome: A hoped-for effect on weight

Human evidence: No effect on weight was seen in the review of herbal medicines for weight loss.

Limits: Trials found no benefit.

Interactions and precautions: A 2025 review described liver injury cases linked to Garcinia supplements. Avoid.

^22,26

Garcinia cambogia →

Fat burners, thermogenic blends and detox teas

Evidence against

Studied form and route: Pills, powders and teas

Intended outcome: Claims of boosted metabolism or 'detox'

Human evidence: The FDA warns that many weight-loss pills, supplements and teas are likely to be contaminated with dangerous hidden ingredients. In the review of 54 trials, combination products had statistically but not clinically significant differences, and the authors found insufficient evidence to recommend any herbal medicine for weight loss. Proper evidence not found for detox teas.

Limits: Product contents vary and are often not what the label says.

Interactions and precautions: Can cause serious harm. Do not use, especially in pregnancy, with medicines, or with heart or liver conditions.

Therapies & care

Established professional care for a stall starts with a conversation: a clinician can check for medicines or health problems that affect weight, and a registered dietitian or structured program can adjust your plan safely. This page does not recommend any medicine or dose. Prescription weight-loss medicines and surgery are options that a doctor decides on for some people, and they are described on the medical care page. Never stop a prescribed medicine on your own.

Medicines and health check with a doctor

Moderate certainty

Medical review NIDDK says your health professional may ask about your habits, review your medical problems, and review the medicines and supplements you take to see whether they affect your weight or your ability to lose it. NHS says a GP can also help with other conditions that might be affecting weight, such as mental health conditions.

Who it may suit: Anyone whose weight has stalled despite a steady plan, or who has other symptoms.

Precautions: Bring a full list of medicines and supplements. Do not stop a medicine without advice.

^3,8,7

Medicines that can change weight →

Registered dietitian

Moderate certainty

Nutrition counselling NIDDK says a health professional may refer you to a registered dietitian. A dietitian can help check your intake, set safe targets and plan meals.

Who it may suit: Adults who need individual guidance, including people with diabetes or other conditions.

Precautions: Choose a registered professional. Avoid anyone selling supplements.

Structured weight-management program

Moderate certainty

Behavioral program NIDDK describes a formal program as one that gives ongoing guidance, a healthy lower-calorie plan, an activity plan, support for setting goals and overcoming setbacks, and a plan for keeping the weight off. NHS says weight management programmes can help support you to lose weight safely and keep it off.

Who it may suit: Adults who benefit from structure and support.

Precautions: Check the program with the questions NIDDK suggests; avoid programs that promise very rapid loss.

^3,8

Support for emotional eating and mental health

Moderate certainty

Psychological support NHS says a GP can help you get support for other conditions affecting your weight, such as mental health conditions. If a plateau brings up distress, bingeing or rigid food rules, professional support matters more than another diet.

Who it may suit: People with distress about food, or a history of disordered eating.

Precautions: Seek help early; do not wait for the scale to move.

⁸

Eating disorders and disordered eating →

Prescription weight-loss medicines and surgery

Medical treatment (doctor's decision) NHS says a GP can refer you for treatment including weight management programmes, medicines and surgery. NIDDK says health professionals most often recommend lifestyle changes along with medicines or surgery. This page did not review their trial evidence, so no evidence rating is given; see the educational overview.

Who it may suit: Some people with obesity or weight-related conditions, as decided with a doctor.

Precautions: These need medical supervision and a doctor's decision.

^8,3

Weight-loss medications and medical care →

What to avoid

Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.

Risks that apply to most people

Sharp calorie cuts, crash diets and skipping meals

Moderate certainty

Why: After a very low energy diet in a study of 50 adults, appetite hormones and hunger had still not returned to baseline a year later, which can make keeping weight off harder. NIDDK recommends realistic goals and a plan you can maintain.

Who it applies to: Anyone frustrated by a stall.

Try instead: Make small, sustainable changes and ask a dietitian for tailored guidance.

^5,3,2

Weight and metabolism safety →

Laxatives, diuretics, purging or extreme exercise to push the scale down

Not enough evidence

Why: These are unsafe ways to lose weight and can be signs of disordered eating. They can cause dehydration and other harm.

Who it applies to: Anyone, especially if you feel driven to do this.

Try instead: Talk to a doctor. If you feel unable to stop, see the eating disorders page.

Eating disorders and disordered eating →

Personal triggers to check

Short or broken sleep

Low certainty

Why: NIDDK says not getting enough sleep is linked to weight gain and may make you hungrier. In a trial, adults who slept longer ate fewer calories.

Who it applies to: People who sleep under 7 hours.

Try instead: Protect sleep time and see the sleep pages.

^7,16

Build a Healthy Sleep Schedule →

Under-counting food and over-counting activity

Low certainty

Why: In a classic study of people who believed they could not lose weight on a low-calorie diet, intake was about 47% higher and activity about 51% lower than reported, while energy use was normal.

Who it applies to: Anyone, not a sign of dishonesty. It is easy to miss drinks, snacks and portions.

Try instead: Do a short, honest check, unless it is risky for you.

⁶

Medicines and health conditions that raise weight

Moderate certainty

Why: NIDDK lists some medicines for epilepsy, depression or psychotic disorders, steroids and some diabetes medicines, and conditions such as PCOS, Cushing's syndrome and hypothyroidism.

Who it applies to: People who started a medicine or noticed other symptoms.

Try instead: Ask a doctor or pharmacist to review. Never stop a medicine on your own.

⁷

Medicines that can change weight →

Products that need caution

Fat burners, detox teas and 'weight-loss' supplement pills

Evidence against

Why: The US FDA says many products that claim to help with weight loss, including diet pills, fat-burning pills and weight loss supplements, pills and teas, are likely to be contaminated with dangerous hidden ingredients and are not guaranteed to work. A systematic review of 54 trials found insufficient evidence to recommend any herbal weight-loss medicine.

Who it applies to: Anyone tempted to try a product to break a stall.

Try instead: Use the lifestyle steps on this page and ask a clinician about other options.

^27,22

Weight-loss supplements and fat burners: claim check →

Garcinia cambogia supplements

Evidence against

Why: A review of trials saw no effect on weight, and a 2025 review described liver injury cases linked to Garcinia supplements.

Who it applies to: Anyone considering it.

Try instead: Avoid. See the claim check for details.

^22,26

Garcinia cambogia →

Unsupported claims

'A plateau means your metabolism is broken'

Moderate certainty

Why: Metabolism does adapt to weight loss: energy use falls more than expected for body size, and the effect can persist. But it is a proportional, incomplete response rather than a breakdown; in the 'Biggest Loser' follow-up, metabolic adaptation was about 500 kcal a day after 6 years in 14 people, an extreme case.

Who it applies to: Anyone told to 'fix' their metabolism.

Try instead: Focus on habits you can keep. See the metabolism page.

^28,4

Metabolism myths →

'You just need to cut 3,500 calories a week for each pound'

Moderate certainty

Why: Modelling and supervised experiments show this rule overestimates loss over time, because the body changes as weight comes off.

Who it applies to: Anyone using a calculator that assumes constant loss.

Try instead: Treat predictions as rough, and judge by your trend.

^9,10

Common mistakes

Giving up the whole plan after a stall

Low certainty

Why: A slowdown after the early weeks is expected, as the sources above describe. Stopping everything gives up habits that were working.

Who it applies to: Anyone who feels discouraged.

Try instead: Keep the habits that work and adjust one thing at a time.

Maintain Progress Over Time →

Cutting food further every time progress slows

Not enough evidence

Why: This leads towards very low intakes, which are hard to keep and carry risks. The evidence I read does not show that eating less after a stall is a reliable or safe fix.

Who it applies to: Anyone dieting for a long time.

Try instead: Check tracking, sleep, activity and medicines first; ask a dietitian.

^5,3

Stopping or changing a medicine yourself

High certainty

Why: NIDDK says a clinician can review medicines, which may affect weight. Stopping them yourself can be dangerous.

Who it applies to: People on any prescribed medicine, including diabetes medicines.

Try instead: Talk to your prescriber.

Evidence & safety

What the research shows

The research agrees that weight loss slows over time because the body adapts: it needs fewer calories at a lower weight, hunger hormones change, and habits can drift. Large reviews and official sources (NIDDK, NHS) support realistic goals, activity, sleep, protein and fibre, and professional support. There are few trials of ways to break a plateau itself; ideas such as planned diet breaks come from single small studies, and supplements show small or no effects with safety concerns.

Limits of the evidence

We found no randomized trials that tested ways to get past a plateau specifically; most evidence comes from weight-loss studies in general or from models.
The MATADOR trial was small, in men only, and tested planned breaks rather than plateau-breaking.
Studies of metabolic adaptation include very small or extreme groups, such as the 14 'Biggest Loser' contestants.
Self-monitoring and sleep studies were short, and self-report is imprecise.
Supplement reviews include short, low-quality trials with variable products.

Precautions and interactions

Check supplements and herbs with a pharmacist if you take medicines, particularly for diabetes, blood pressure or mood.
Never stop a prescribed medicine because of weight.
Avoid very low calorie diets unless a clinician supervises them.
Weight loss in diabetes can change medicine needs; ask the prescriber before changing diet.

Life-stage considerations

Pregnancy and breastfeeding: do not try to lose weight on your own; talk to a clinician.
Under 18: weight management needs pediatric guidance.
Older adults: unplanned loss of muscle is a concern, so keep protein and strength work, and ask about unintentional loss.
Midlife and menopause: weight changes are common; see Manage Weight Changes in Midlife.
History of eating disorders: get professional guidance before any weight-loss attempt.

Warning signs

Weight change without trying, up or down, or rapid gain with swelling or breathlessness.
Fear of eating, rigid rules, bingeing, purging, or laxative or diuretic use.
Dizziness, fainting, palpitations or marked tiredness while dieting.
New symptoms after starting a medicine.

Claim checks

A plateau means your metabolism is broken.

Moderate certainty

Partly true, mostly misleading. Metabolic adaptation is real and can persist: in 14 'Biggest Loser' contestants it was about 500 kcal a day below expected at 6 years. But the authors describe it as a proportional, incomplete response to weight reduction, not a breakdown, and in a small study of people who said they could not lose weight, energy use was normal.

^28,6,4

You need a 3,500-calorie shortfall for each pound lost.

Moderate certainty

Oversimplified. The rule overestimates loss over time because energy needs fall and body composition changes as weight comes off.

^9,10

Eating less and less will restart weight loss.

Not enough evidence

Proper evidence not found. We did not find trials showing this is a safe or reliable fix, and very low energy diets were followed by lasting hunger-hormone changes in one study.

^5,3

A 'cheat day' or refeed resets your metabolism.

Low certainty

Not shown. The only supporting study I read tested planned two-week blocks of eating at maintenance, not single cheat days, in men with obesity.

¹⁷

Fat burners, detox teas or supplements can break a plateau.

Evidence against

Not supported, with safety concerns. Reviews found insufficient evidence, and the FDA warns of hidden ingredients.

Questions people ask

How long is a plateau?

There is no fixed length. Weight responds slowly to changes in intake, with half times of about a year in one model, so a flat spell of a few weeks is common. If you have been stuck for more than a month or two despite steady habits, it is reasonable to see a dietitian or doctor.

Is a plateau my fault?

No. The body needs fewer calories as you get smaller, hunger hormones change after weight loss, and habits drift without anyone noticing. A plateau is a normal part of the process.

Does my metabolism slow down when I lose weight?

Yes, to a degree. NIDDK says metabolism slows during weight loss and the body needs fewer calories at the lower weight. Studies show energy use can drop more than expected for the change in body size. It is a proportional response, not a broken metabolism.

Should I eat even less to get past it?

We did not find evidence that eating less and less is a safe or reliable way through a plateau. Very low intakes are hard to keep and carry risks. Check your tracking, sleep, activity and medicines first, and ask a dietitian before reducing further.

Can a medicine or health condition cause a plateau?

It can contribute. NIDDK lists some medicines and conditions that affect weight. Ask a doctor or pharmacist to review them, and do not stop any medicine on your own.

Do supplements, green tea or apple cider vinegar help?

Evidence is weak. A Cochrane review found no clinically important effect of green tea, and a meta-analysis of apple cider vinegar found small, variable short-term effects. The FDA warns about hidden ingredients in many weight-loss products.

Should I do more exercise?

Activity helps with weight loss and keeping muscle, and more than the minimum guidelines is linked to larger loss. Build up gradually, include strength work, and do not use exercise as punishment.

Do cheat days or diet breaks work?

One small trial in men found that planned two-week breaks alternating with dieting led to more weight loss than continuous dieting. It was not tested on plateaus, and nothing I read supports single cheat days.

Is staying at the same weight a failure?

No. Keeping weight steady is a skill in itself, and NHS says even losing 5 to 10% of body weight can improve health. A plateau can be a time to practise keeping it.

When should I see a doctor?

If your weight changes without explanation, if you take medicines or have conditions that may be affecting it, or if food or weight is taking over your thoughts. Fear of eating, bingeing or purging need professional support.
