Approximately 174 kcal for one hour: this is the energy expenditure of a typical Pilates session according to the most reliable estimate from a meta-analysis published in 2026, representing light to moderate intensity. However, studies show a modest effect on weight: in overweight or obese adults, 8 to 24 weeks of Pilates resulted in an average weight loss of 2.4 kg more than non-exercise groups, according to a meta-analysis of 11 trials.

This guide details what studies identified via PubMed show, from session energy expenditure to flat abs, then how to combine Pilates with endurance, caloric deficit, sleep and protein, up to a 12-week program.

In brief

Pilates and weight : one session corresponds to approximately 3 METs, nearly 174 kcal per hour. In overweight or obese adults, 10 trials found an average weight loss of 2.4 kg, 3.3 kg beyond 10 weeks, with weak to moderate level of evidence; another meta-analysis finds floor Pilates not superior to other exercises, and none finds a significant reduction in waist circumference.

Flat abs and strategy : according to most trials, working a muscle does not melt the fat covering it, but Pilates strengthens the abdominal muscles (25.6% more abdominal endurance in 8 weeks in one trial). Combining diet and activity results in 6.3 kg more weight loss than activity alone at 12 to 18 months; endurance, walking, sleep and protein complement Pilates.

Quick answer
Pilates can lead to weight loss, but modestly. A session burns approximately 174 kcal per hour, and in overweight or obese adults, 10 trials found an average weight loss of 2.4 kg over 8 to 24 weeks, with weak to moderate evidence. It strengthens the abdominal muscles without targeting belly fat. For a flatter stomach, studies primarily support its combination with 150 to 300 minutes of endurance exercise per week and a caloric deficit ; daily steps, sufficient sleep, and 1.2 to 1.6 g of protein per kilogram of body weight per day help with weight loss or muscle preservation.

How many calories does a Pilates session burn?

Light to moderate intensity, around 3 MET: the duration of rest periods matters as much as the choice of exercises.

Researchers compare activities using MET: 1 MET corresponds to energy expenditure at rest while sitting, and an activity becomes moderate between 3 and 6 MET. The Compendium of Physical Activities classified traditional mat Pilates at 1.8 MET in 2024 and Pilates in general at 2.8 MET, according to a 2026 meta-analysis that gathered 6 studies measuring session energy expenditure in young healthy adults, predominantly women.

Exploratory meta-analysis, Systematic Reviews 2026

A Pilates session mobilized an average of 3.7 MET. Considering only the 4 studies with low risk of bias that measured gas exchange, the estimate drops to 3.0 MET and 2.9 kcal per minute, or approximately 174 kcal for a 60-minute session. The authors considered the intensity light to moderate and the level of evidence very weak to weak.

Vitor GBB, de Oliveira LC, Pessôa RAG, et al. Syst Rev 2026;15(1):42. DOI: 10.1186/s13643-025-03056-y

The duration of rest periods can nearly double energy expenditure: approximately 2.0 MET with more than 60 seconds of rest between exercises, versus 3.4 MET with 60 seconds or less, a finding the authors still consider fragile. Format also matters: in 18 young women of normal weight, a 15-exercise reformer session burned 2.59 kcal per minute, compared to 1.93 kcal on a mat, with no significant increase in lactate, heart rate, or blood pressure compared to rest.

Format Measured expenditure Study
Mat Pilates, 15 exercises, young women 1.93 kcal per minute, or approximately 116 kcal per hour de Souza Andrade, 2021
Reformer Pilates, same participants 2.59 kcal per minute, or approximately 155 kcal per hour de Souza Andrade, 2021
Typical session, 4 most reliable studies 3.0 MET and 2.9 kcal per minute, approximately 174 kcal per hour Vitor, 2026
In practice

At 2.9 kcal per minute, three one-hour sessions represent approximately 520 kcal per week: a useful boost, not the primary driver of weight loss. For a more intense session, limit rest periods to 60 seconds. Our guide how many calories per day to lose weight situates this expenditure within your daily intake.

Weight and fat mass: what meta-analyses show

Modest weight loss in case of overweight or obesity, uncertain results on fat mass and waist circumference.

A meta-analysis published in 2021 grouped 11 randomized trials in 393 overweight or obese adults, three-quarters of them women, most often exercising three times per week for 60 minutes over 8 to 24 weeks. Control participants did not exercise and trials with dietary interventions were excluded: the measured effect is that of Pilates alone.

Meta-analysis of 11 randomized trials, Frontiers in Physiology 2021

Compared with no exercise, Pilates reduced weight by an average of 2.40 kg, body mass index by 1.17 points, and fat mass percentage by 4.22 points, without changing lean mass. Weight loss reached 3.30 kg in trials lasting more than 10 weeks and 3.81 kg in obese individuals; it was not significant in shorter trials or in those who were merely overweight. Waist circumference, measured in 2 trials, did not decrease significantly.

Wang Y, Chen Z, Wu Z, et al. Front Physiol 2021;12:643455. DOI: 10.3389/fphys.2021.643455

These figures warrant caution: the trials included 20 to 61 participants, the authors judged the level of evidence weak to moderate for weight, very weak to weak for fat mass, and the weight result was no longer significant without one of the trials.

A 2026 meta-analysis limited to adult women, 12 studies of which some were not randomized, found a weight loss of 3.99 kg across 5 studies and body mass index reduction of 1.22 points across 8, with no significant effect on fat mass percentage, lean mass, or waist circumference. A third, devoted to mat Pilates in healthy adults (10 studies), found it no better than traditional exercise or no intervention, including in cases of overweight or obesity; to explain this, the 2021 authors suggest insufficient intensity and uncontrolled diet.

What can be expected from it

These results are group averages, often in sedentary individuals. The response varies from person to person, and no individual figure can be promised; the effect appears more pronounced in longer programs and in cases of obesity.

Trial by trial: what Pilates really changes

Often few kilos lost on the scale, but slightly less fat and slightly more muscle.

The most instructive trial compares Pilates, mat and apparatus-based, with walking in overweight or obese adults: three 60-minute sessions per week for 8 weeks, without changes in caloric intake.

Comparative trial, PeerJ 2019

In 22 overweight or obese adults, 8 weeks of Pilates decreased fat mass from 50.9 to 49.1% of body weight and increased lean mass from 38.4 to 39.7 kg, effects deemed small, whereas weight did not change in either group. Waist circumference decreased by 2.6% with Pilates and 3.3% with walking. After the intervention, body composition did not differ between groups.

Rayes ABR, de Lira CAB, Viana RB, et al. PeerJ 2019;7:e6022. DOI: 10.7717/peerj.6022

The other trials, conducted in women, show modest effects, sometimes none.

Participants Program Result Study
28 young obese women with elevated blood pressure Mat Pilates, 12 weeks Fat mass decreased by 2 points and systolic pressure by 5 mmHg with Pilates, significant decreases compared to controls Wong, 2020
47 overweight or obese women Pilates on reformer, 3 sessions per week, 8 weeks Weight from 76.0 to 74.7 kg, fat mass from 39.3 to 37.3%, slightly increased in controls Gökalp, 2025
35 obese women on Mediterranean diet Online Pilates at home, 3 hours per week, 12 weeks Fat mass decreased and muscle mass increased with Pilates only Greco, 2024
58 women with or without obesity Pilates, 2 sessions per week, 8 weeks Increase in BMI and fat mass prevented in case of obesity; improved posture Arslan Kabasakal, 2025
42 inactive women Pilates or light group strength training class, 3 months Improved body composition through group fitness classes; flexibility only with Pilates Evangelou, 2021

The scale doesn't tell the whole story: in several trials, weight changed little while fat mass decreased and muscle mass increased. The most clear results appear in cases of obesity, in longer programs or with structured nutrition; in the trial conducted with 58 women, emotional eating also decreased among obese participants.

Flat belly: abdominal fat and waist circumference

Visceral fat responds to physical activity, and waist circumference reflects it better than the scale.

The belly stores two types of fat: subcutaneous fat, which you can pinch, and visceral fat, around the organs, which contributes to cardiometabolic risk and is partly reflected in waist circumference. In a meta-analysis of 25 trials involving 1,686 overweight or obese adults, regular endurance activity reduced waist circumference by 3.2 cm compared to controls, a decrease associated with reduced visceral fat, with 4.2 cm at vigorous intensity versus 2.50 cm at moderate intensity.

Dosage matters: according to a meta-analysis of 116 trials, each additional half-hour of weekly endurance was associated with 0.52 kg and 0.56 cm less waist circumference; weight decreased linearly up to 300 minutes, dropping 2.79 kg at 150 minutes and 4.19 kg at 300 minutes, and waist circumference by 4.21 to 5.34 cm at 300 minutes depending on intensity. Another meta-analysis of 40 trials shows that exercise reduces visceral fat, especially when weekly energy expenditure is higher, with an effect size of 0.28, compared to 0.53 for caloric restriction.

Understanding effect size

Effect size compares the difference between two groups relative to the spread of measurements: 0.2 corresponds to a small effect, 0.5 to a medium effect, 0.8 to a large effect.

For Pilates alone, waist circumference reduction was not significant in any of the three meta-analyses; in the comparative trial, it reached 2.6% with Pilates and 3.3% with walking.

Waist circumference, a better indicator than the scale

Measure it midway between your last rib and the top of your hip bone, as in the comparative trial, in the morning and always at the same location, every two to four weeks. Our guide for achieving a flat belly and our 20 tips for losing belly fat detail the other approaches.

The myth of spot fat loss

Working a muscle does not melt the fat covering it: this is what most trials show.

Doing abdominal exercises to lose belly fat seems logical; most trials don't confirm this. In 24 sedentary adults, 7 abdominal exercises, performed as 2 sets of 10 repetitions 5 days per week for 6 weeks, did not change weight, abdominal fat, waist circumference, or abdominal skin folds. Abdominal endurance, however, improved: 47 sit-ups in the final test, compared to 32 in the control group.

Controlled trial, Journal of Strength and Conditioning Research 2013

Eleven young adults trained one leg only for 12 weeks, 3 times per week, with 960 to 1,200 leg press repetitions per session at light load (10 to 30% of maximum). Total fat mass decreased by 5.1%, but not on the trained leg: fat decreased on the arms by 10.2% and on the trunk by 6.9%.

Ramírez-Campillo R, Andrade DC, Campos-Jara C, et al. J Strength Cond Res 2013;27(8):2219-2224. DOI: 10.1519/JSC.0b013e31827e8681

Adding abdominal exercises to a diet makes no difference: in 40 overweight or obese women, 12 weeks of abdominal strengthening in addition to a diet did not reduce subcutaneous belly fat, measured by ultrasound, or waist circumference more than diet alone.

The Hundred and abdominal exercise sequences strengthen the core without burning the fat covering it: this decreases with total fat mass, not necessarily where you train. This principle applies to the thighs, as explained in our article for losing thigh fat, and for abdominal muscles, detailed in our guide for getting visible abs.

6

Abdominal wall, posture, and bloating

Pilates strengthens the abdominal wall and teaches you to control it, without directly affecting fat.

Pilates stands out for its effect on abdominal wall muscles. In an MRI study of 9 inactive women, 36 weeks of Pilates, twice per week, increased rectus abdominis volume by 21% and oblique and transverse muscle volume on the dominant side by 8%, correcting an asymmetry present at baseline. The study, without a control group, involved a small sample.

In a randomized trial of 50 active middle-aged adults, 12 weeks of mat Pilates, two one-hour sessions per week, improved abdominal endurance, hamstring flexibility, and upper body endurance, but not posture or balance compared to the control group. On a reformer, in overweight or obese women, trunk flexion hold time increased from 15.3 to 27.4 seconds in 8 weeks.

The transverse, the deep core belt of the belly, activates more after training, but only during the trained exercises. In an 8-week trial of 34 adults, those who practiced mat Pilates alone twice per week saw their transverse thicken during the Hundred, from 3.7 to 4.7 mm, with no change at rest or in sitting or standing position. Practical tip: reproduce the gentle belly draw-in you learned on the mat throughout the day. For this work, our NUTRITION•PRO Pilates Mat, in microsuede on non-slip rubber, anchors every posture.

There remains the belly that bloats after meals, unrelated to fat. In people with functional digestive disorders, it's linked to an inappropriate reflex: the diaphragm contracts while the abdominal wall relaxes. In a 2024 randomized trial of 42 patients, biofeedback training to mobilize the diaphragm, with home exercises three times daily, reduced bloating scores by 66% in 4 weeks, with no effect in the placebo group.

Pilates was tested in a randomized trial of 60 women with irritable bowel syndrome with constipation: added to dietary advice, two sessions per week for 8 weeks reduced overall symptom scores by 67%, compared to 38% with advice alone, and bloating sensation by 69%, compared to 27%. However, the Pilates group started with a higher baseline bloating score, and evaluators knew which groups participants were in. Our article on bloating details other approaches.

Asian Pilates, wall Pilates: what we know

Two trends without dedicated trials: research on Pilates in general tells us what can be expected from it.

Neither wall Pilates nor Asian Pilates are codified methods, but formats popularized by social media: the first incorporates floor exercises with wall support, the second refers to short, slow routines without jumping, practiced at home, combining core work, leg exercises, and stretching.

A PubMed search in October 2026 found no articles with wall Pilates or Asian Pilates in the title or abstract: nothing specific to these formats can be confirmed. At 2.9 kcal per minute, a 15-minute routine represents approximately 45 kcal, and practiced daily for 1 hour 45 minutes per week, it falls short of the three weekly hours used in most trials that measured weight loss.

Randomized trial, Nutrients 2024

In obese women all following a Mediterranean diet, 12 weeks of floor Pilates at home, three one-hour sessions per week including one guided online, reduced body fat percentage and increased muscle mass, unlike diet alone. Weight decreased in both groups. Of 35 participants, 20 completed the study.

Greco F, Tarsitano MG, Cosco LF, et al. Nutrients 2024;16(6):902. DOI: 10.3390/nu16060902

Practiced at home, Pilates can produce measurable effects, with sufficient volume and structured nutrition. Study limitation: 43% dropout rate. Consistency makes the difference.

Pilates, yoga, or cardio for weight loss?

For calorie expenditure, endurance performs better; for core and flexibility, Pilates is superior; the ideal is to combine them.

Yoga has similar intensity, 2.9 to 3.3 MET on average according to a review cited by the 2026 meta-analysis. A meta-analysis of 30 trials and 2,173 participants found no overall effect on weight, body mass index, body fat, or waist circumference; in overweight or obese individuals, it reduces body mass index compared to usual care, a result sensitive to selection bias according to the authors.

Endurance maintains the advantage for calorie expenditure: in the comparative trial, heart rate during walking exceeded that of Pilates by 42%. However, in the same trial, abdominal endurance improved by 25.6% with Pilates versus 11.0% with walking, and only the Pilates group improved back muscle endurance and flexibility.

Activity Intensity Effect on weight and belly
Pilates, on the floor or on a reformer Approximately 1.8 to 3.4 MET depending on format and breaks 2.4 kg lost on average in case of overweight or obesity (10 trials); waist circumference not significant
Yoga Approximately 2.9 to 3.3 MET on average No overall effect on weight; BMI reduced in case of overweight or obesity, fragile result
Endurance, brisk walking, cycling, running Moderate, 3 to 6 MET, or vigorous 0.52 kg and 0.56 cm less waist circumference per half-hour weekly
Group strength training with light weights Numerous repetitions Body composition improved in 3 months, more than with Pilates in one trial

Combine Pilates, endurance, walking, and caloric deficit

Activity alone produces little weight loss; combined with nutrition, it helps lose more and preserve muscle.

The body compensates for part of the energy expended by exercise: 18% on average according to a review of 61 studies, with significant variation from one study to another, and nearly 84% in the longest programs, lasting approximately 80 weeks. This is one of the reasons why activity alone has little impact on the scale.

Meta-analysis of direct comparisons, Journal of the Academy of Nutrition and Dietetics 2014

In 8 trials of at least 12 months of follow-up involving 1,022 overweight or obese adults, mostly women, programs combining diet and physical activity resulted in 5.33 kg more weight loss than activity alone at 3 to 6 months, and 6.29 kg more at 12 to 18 months (5 trials). Compared to diet alone (6 trials), the difference was not significant at 3 to 6 months, but reached 1.72 kg at 12 months.

Johns DJ, Hartmann-Boyce J, Jebb SA, et al. J Acad Nutr Diet 2014;114(10):1557-1568. DOI : 10.1016/j.jand.2014.07.005

Activity also preserves muscle: in a review of 52 studies in middle-aged and older overweight adults, in 81% of diet-only groups, at least 15% of weight lost was lean mass, compared to 39% of groups combining diet and exercise. And according to a meta-analysis of 116 trials, 150 minutes of endurance per week, at least moderate intensity, are associated with clinically meaningful reductions in waist circumference and fat mass: Pilates complements this foundation without replacing it.

Without diet, walking with a pedometer produces minimal weight loss: 1.27 kg over a median duration of 16 weeks, according to a meta-analysis of 9 studies. In programs combining diet and activity, a meta-analysis of 2026 shows that participants increased from approximately 7,500 to 8,450 steps per day, and the more they walked, the better they maintained their weight loss, a simple association; the authors suggest a benchmark of approximately 8,500 steps per day. Our guide walking to lose weight details step targets, and our article why I'm not losing weight despite exercise and diet reviews common obstacles.

Sleep also matters. In a randomized trial of 80 overweight adults sleeping less than 6 hours 30 minutes per night, those who received personalized sleep hygiene advice slept 1.2 hours more and reduced their intake by 270 kcal per day compared to the control group, with a 0.87 kg weight difference in two weeks, mostly from non-fat mass at such short term; limiting screens appeared to be the key measure, and these longer nights were achieved through advice, without supplementation.

Protein: preserving muscle during weight loss

More protein in a caloric deficit: slightly more fat lost, slightly more muscle preserved.

When eating less, the body also draws from muscle. A meta-analysis of 24 trials, 1,063 participants followed for an average of 12 weeks, compared high-protein or standard-protein diets at equal calories: the former resulted in 0.79 kg more weight loss and 0.87 kg more fat loss, preserved 0.43 kg of lean mass, and limited the decrease in resting metabolic rate; 3 out of 5 studies reported better satiety.

An expert review proposes 1.2 to 1.6 g of protein per kilogram per day, with at least 25 to 30 g per meal, or 84 to 112 g per day for 70 kg. In women, a meta-analysis of 13 trials shows that whey modestly increases lean mass by 0.37 kg, and by 0.90 kg during caloric restriction, with no effect on fat mass.

Randomized PRISE trial, Journal of Applied Physiology 2014

In overweight or obese adults who added three 20 g servings of whey per day to their usual diet, 16 weeks of a mixed program combining strength training, intervals, stretching, yoga or Pilates, and endurance resulted in 3.3 kg weight loss, including 2.8 kg fat loss, compared to 1.1 kg and 0.9 kg with strength training alone. Only the two trained groups lost visceral fat. All groups taking whey, the trial compares training methods, not whey versus its absence.

Arciero PJ, Baur D, Connelly S, Ormsbee MJ. J Appl Physiol 2014;117(1):1-10. DOI : 10.1152/japplphysiol.00152.2014

To approach 25 to 30 g of protein per meal, a 30 g serving of our 100% Whey Isolate provides 22.9 g of protein for 117 kcal, with 1.3 g sugars and 2.0 g fat: enough to complement a protein-poor meal. Our guides on whey, protein during cutting and high-protein foods further elaborate on this point.

Precautions

Pain : stop any exercise that causes pain in the back, neck, or abdomen. Pregnancy and postpartum : consult your doctor or midwife before abdominal work. Cardiovascular disease, diabetes, significant obesity : have your endurance intensity validated. Kidney disease : consult your doctor before increasing protein intake. Caloric deficit : without activity, it causes greater muscle loss; in case of severe restrictions, seek professional guidance.

Frequently asked questions

Does Pilates help you lose weight?

Somewhat, especially in cases of overweight or obesity. In these adults, a meta-analysis of 11 trials found an average weight loss of 2.4 kg in 8 to 24 weeks compared to no exercise, and 3.3 kg beyond 10 weeks, with weak to moderate level of evidence.

How many calories does a Pilates session burn?

Approximately 2.9 kcal per minute according to the most reliable estimate from a 2026 meta-analysis, or nearly 174 kcal for one hour. In one trial, the treadmill expended 1.93 kcal per minute and the reformer 2.59.

Does Pilates give you a flat stomach?

It strengthens the core muscles, but does not specifically melt belly fat. To reduce waist circumference, studies support combining it with 150 to 300 minutes of cardio per week and a caloric deficit.

How many Pilates sessions per week to lose weight?

Most trials that measured weight loss offered three sessions of 50 to 60 minutes per week, with significant effects after 10 weeks. Ideally add 150 minutes of cardio per week and a moderate caloric deficit.

Pilates or yoga: which one for weight loss?

Both have similar intensity, around 3 MET. A meta-analysis of 30 trials found no overall effect of yoga on weight, whereas Pilates modestly reduces weight in cases of overweight or obesity, with still fragile evidence in both cases.

Does wall Pilates reduce belly fat?

No trial has studied wall Pilates, which uses floor exercises with wall support. Pilates in general expends little and produces minimal weight loss, and most trials show no targeted reduction of belly fat.

Does Asian Pilates help you lose weight?

No study addresses Asian Pilates, a social media trend consisting of short, slow routines. At approximately 2.9 kcal per minute, a 15-minute routine represents nearly 45 kcal, and trials that measured weight loss most often relied on three hours of Pilates per week.

Do abdominal exercises reduce belly fat?

Not in a targeted way, according to most trials. In one trial, 6 weeks of abdominal exercises, 5 days per week, reduced neither abdominal fat nor waist circumference, despite improved endurance. In another, training a single leg for 12 weeks reduced fat in the arms and trunk, not in the trained leg.

Should you take protein when doing Pilates to lose weight?

During a caloric deficit, more protein helps preserve lean mass: 0.43 kg more on average in a meta-analysis of 24 trials. An expert review proposes 1.2 to 1.6 g per kilogram per day, which an isolate whey can help you achieve.

Does Pilates reduce bloating?

In 60 women suffering from irritable bowel syndrome with constipation, 8 weeks of Pilates added to dietary advice reduced the sensation of bloating by 69%, compared to 27% with advice alone, in a group that started with a higher baseline score.
