Does yoga help in weight management? Most definitely. There are a number of factors involved. Firstly, some of the asanas stimulate sluggish glands to increase their hormonal secretions. The thyroid gland, especially, has a big effect on our weight because it affects body metabolism. There are several asanas, such as the shoulder stand and the fish posture, which are specific for the thyroid gland. Fat metabolism is also increased, so fat is converted to muscle and energy. This means that, as well as losing fat, you will have better muscle tone and a higher vitality level.

Secondly, yoga deep breathing increases the oxygen intake to the body cells, including the fat cells. This causes increased oxidation or burning up of fat cells. Yogic exercises induce more continuous and deeper breathing which gradually burns, sometimes forcefully, many of the calories already ingested.

Thirdly, yogic practices that reduce anxiety tend to reduce anxious eating. When under nervous strain we tend to gulp our food without attaining much genuine satisfaction. We end up in eating more. If, on the other hand, we approach our meals with greater calmness of mood, whether produced by habits which have calmed our life or by yoga (like a pause for prayer before a meal), we tend to be less likely to overeat in a frantic effort to quiet our midday anxieties.

Lastly, yogic aids may be employed between meals whenever one becomes tempted to search for a snack. One may deliberately turn to yoga, rather than to the icebox or snack bar, when he feels the need for a lift or relief from restless nervousness. Practicing yoga may make you aware of your weight problem that may also act as a deterrent from overeating.

If you are not overweight, your weight will remain about the same. If you are underweight, you will gain weight. The weight you gain will be healthy firm tissue, not fat. That is, yoga will tend to produce the ideal weight for you. This is due to yoga's effect of 'normalizing' glandular activity.

For those whose eating habits, whether at meals or between meals, are believed to be due to feelings of weakness rather than anxieties, most yogic postures and breathing exercises are designed to increase one's strength. Hence, they may relieve feelings of weakness more effectively than additional eating. The exercises themselves, although consuming some energy, also store up energy which, when combined with oxidizing breathing, provide energy that is ready for use rather than for storage.
