Yoga and weight loss: an honest look
3 min read · Updated October 17, 2026 · sources checked October 17, 2026
In short
Yoga on its own is not an efficient way to lose weight. Most yoga is light activity, around 2 to 3 METs, and meta-analyses find no clear effect on weight or BMI overall, with a possible effect in people who are overweight that is not robust. Its value lies elsewhere, in regular movement and in habits.
How much energy yoga really uses
Exercise scientists measure effort in METs: one MET is the energy cost of sitting quietly, defined as about 1 kcal per kilogram of body weight per hour. The 2024 Compendium of Physical Activities, the reference table used by researchers, lists:
| Activity | METs (Compendium 2024) | Roughly, per hour, for 70 kg |
|---|---|---|
| Sitting quietly | 1.0 | 70 kcal |
| Nadi shodhana (alternate nostril breathing) | 2.0 | 140 kcal |
| Hatha yoga | 2.3 | 160 kcal |
| Vinyasa yoga | 2.7 | 190 kcal |
| Hot yoga | 3.0 | 210 kcal |
| Sun Salutations (Surya Namaskar) | 3.5 | 245 kcal |
| Power yoga | 4.0 | 280 kcal |
| Brisk walking, 3.5 to 3.9 mph | 4.8 | 335 kcal |
The last column is our rough calculation (METs × 70 kg × 1 hour), including the energy you would spend at rest anyway. A systematic review of studies that measured yoga in the laboratory came to the same picture: full sessions averaged about 2.9 METs once one outlier was set aside, single postures about 2.2 and breathing exercises about 1.3. Most yoga is light activity; a few sequences, Sun Salutations in particular, reach moderate intensity.
What the trials show on weight
The main meta-analysis (2016). Thirty randomised trials with 2,173 people: no effect of yoga on weight, body mass index, body fat or waist size overall. In people who were overweight or obese, body mass index fell compared with usual care, but the authors note that this result was not robust to selection bias and that publication bias could not be ruled out. They conclude, cautiously, that yoga can be "preliminarily" considered for this group.
A more recent review (2023). Fifteen trials with 1,161 people with obesity: against control groups, no difference in body weight, body mass index or body fat. A few trials comparing yoga with calorie restriction or with other exercise favoured yoga on weight, but the authors call all these findings not robust, owing to a high risk of bias. They judged the evidence very low to moderate and concluded that it is "inconclusive" whether yoga improves these measures.
In short: the honest answer is a small effect, possibly, in some people, with weak evidence.
Where yoga may genuinely help
Habits, not calories. In a cohort of 15,550 adults aged 53 to 57, people who had practised yoga for four years or more had gained less weight since age 45, most clearly among those who were overweight. This was an observational study based on remembered weights, so it cannot show that yoga caused the difference.
Attention while eating. In a 2009 survey of 303 adults, yoga practice was associated with higher scores on a mindful eating questionnaire, while walking and other physical activity were not, and higher scores went with a lower body mass index. A survey shows an association, not an effect.
These two studies echo something the hatha texts already said. The Hatha Yoga Pradipika counts moderate eating, mitāhāra, among its ten restraints (1.17 in the GRETIL edition) and defines it a few verses later:
susnigdha-madhurāhāraś caturthāṃśa-vivarjitaḥ / bhujyate śiva-samprītyai mitāhāraḥ sa ucyate
Food that is rich and sweet, eaten leaving a quarter (of the stomach) empty, as an offering to please Śiva: this is called moderate eating.
Our page on the yamas and niyamas explains the discipline of restraint behind it.
What this means for you
- Count yoga as movement, not as a diet. If weight matters for your health, combine it with walking or other moderate activity and with the way you eat, ideally with advice from a doctor or dietitian.
- Choose the practice you will keep. Dynamic sequences such as the Sun Salutation cost more energy than gentle postures, but only if they suit your body.
- Be wary of promises. We found no trial showing that a pose "melts belly fat" or that twisting "detoxes" the body.
- Hot rooms add little. The Compendium puts hot yoga at 3.0 METs, below brisk walking. Read our page on hot yoga and its precautions before trying it.
If you are starting from scratch, a short daily practice is easier to keep than an ambitious plan. Our page on yoga at home shows how to begin, and our book Begin Yoga at Home: 30 Days writes out thirty sessions step by step, with an easier version of every posture.
Questions people ask
Is yoga good for weight loss?
Not on its own. A meta-analysis of 30 trials found no effect on weight, BMI, body fat or waist size overall; in people who were overweight or obese, BMI fell compared with usual care, but the result was not robust. A 2023 review called the evidence inconclusive. Yoga can be part of an active life, not a weight-loss method.
How many calories does yoga burn?
The Compendium of Physical Activities gives 2.3 METs for hatha yoga, which is roughly 160 kcal in an hour for a person of 70 kg, about 70 of which that person would use sitting quietly anyway. Power yoga is listed at 4.0 METs and Sun Salutations at 3.5; brisk walking is 4.8.
Does hot yoga help you lose more weight?
Not much more. The Compendium lists hot yoga at 3.0 METs, a little more than hatha yoga at 2.3 and less than brisk walking at 4.8. Heat also brings its own risks: see our page on hot yoga.
Which yoga is best for weight loss?
No style has been shown to work better for weight. Measured energy costs are higher for dynamic sequences such as Sun Salutations or power yoga than for gentle hatha, but the practice that matters is the one you keep doing alongside walking and the way you eat.
