The principle of yoga for weight loss: the combined effect of breathing, postures, meditation, and diet.

II. The Weight Loss Principles of Yoga

The traditional principle of exercise for weight loss is to increase calorie expenditure compared to calorie intake. Yoga's weight loss effects also follow this basic principle. However, yoga's weight loss principle is not solely based on physical postures that accelerate metabolism and burn excess body fat. Yoga believes that the main cause of obesity is disordered endocrine and digestive systems. Therefore, by regulating these systems through yoga practice, effective and lasting weight loss can be achieved. Yoga practice integrates breathing techniques, postures, and meditation, each of which has direct or indirect effects on weight loss.

(a) Yoga breathing techniques are beneficial for weight loss.

Breathing is the most important human function, yet people know very little about it and often breathe incorrectly. In daily life, due to human factors, most people's breathing is irregular, shallow, and unpredictable, violating the natural rhythm of the body's respiratory system. As a result, the body cannot absorb enough cosmic energy, the nervous system is gradually damaged, the endocrine system cannot function properly, leading to appetite control and digestive disorders, abnormal metabolism, and ultimately obesity.

The unique breathing techniques in yoga practice, which involve deeper and longer breaths than usual, significantly increase oxygen supply, purify the blood, and strengthen lung tissue. Adopting this correct breathing method offers several benefits for weight loss.

1. Promotes normal nervous system function and effectively suppresses appetite.

When breathing using the correct breathing method, breathing becomes calm and the excitability of the cerebral cortex is low. This effectively regulates the brain's appetite control, preventing overeating. This is similar to the effect of taking weight-loss drugs like fenfluramine, which acts on the satiety center in the feeding center, reducing nerve excitability and decreasing a person's excitement about food and impulse to overeat, while without the side effects of medication.

2. Promotes normal digestive system function and prevents fat accumulation.

During breathing, the diaphragm moves up and down, which massages and improves the self-regulation of internal organs. It also strengthens intestinal peristalsis and effectively prevents constipation. This is similar to the effect of a mild laxative, preventing excess food from being stored as fat in the body.

3. Promotes aerobic metabolism and accelerates fat breakdown.

The breathing method, with its unique breathing movements, accelerates blood circulation and increases the amount of oxygen transported by the blood per unit time, thus creating conditions for aerobic metabolism during exercise. In this way, the body can accelerate the breakdown of fat and prevent obesity.

4. Promotes localized weight loss

Because some special breathing techniques in yoga require the abdominal muscles to move constantly, such as compound breathing and pump breathing, this effectively exercises the abdomen, mobilizes abdominal fat, and achieves the effect of localized weight loss.

(ii) Yoga postures are beneficial for weight loss.

Yoga postures, like other traditional exercise methods for weight loss, follow the principle of making the body burn more calories than it takes in. However, due to the variety of postures, each has its own specific purpose, and the benefits of yoga for weight loss are mainly reflected in the following aspects.

1. Promotes full-body muscle movement and prevents localized fat accumulation.

Yoga postures are a full-body exercise that works not only the large muscles and muscle groups of the body but also the various small muscle groups. This avoids the drawback of general exercises where localized strain is excessive and the whole body is not exercised. As a result, certain areas of the body that are prone to fat accumulation can also be effectively stimulated, such as the waist, hips, and thighs of women, and the waist, abdomen, and jaw of men, thus preventing the formation of localized "fat".

2. Regulates metabolism and effectively burns excess fat.

Yoga postures stretch muscles longitudinally as much as possible, allowing fat to be reduced from around cells, improving metabolism, promoting cell division and renewal, and adjusting the metabolic rate that slows down with age. Maintaining a healthy metabolic rate helps burn excess body fat, thereby reducing body fat mass, lowering body mass index, and achieving weight loss and weight control.

3. Reduces the volume of human muscles

Yoga postures primarily involve slow and continuous stretching with low intensity. Skeletal muscle contractions include concentric contraction of agonist muscles, eccentric contraction of antagonist muscles, and isometric contraction between agonist and antagonist muscles. The tension during contraction is low, and the speed is slow. Therefore, muscle fibers rotate during movement, with the mobilization of slow-moving units (slow-twitch muscle fibers) being the primary focus. Long-term yoga practice can cause adaptive hypertrophy of slow-twitch muscle fibers and disuse atrophy of fast-twitch muscle fibers. As is well known, slow-twitch muscle fibers are small in diameter and volume, while fast-twitch muscle fibers are relatively large. Therefore, the overall effect of muscle adaptation brought about by yoga training is a reduction in muscle volume.

4. Easy to stick to, increases the body's calorie consumption.

Yoga is a long-duration exercise, with a complete session lasting over an hour. Within the energy continuum, it is primarily an aerobic exercise. The phosphagen and glycolytic systems play a relatively limited role in yoga practice, resulting in less lactic acid production and thus less exercise-induced fatigue and the sensation of fatigue. Practitioners can enjoy extended sessions with a pleasant and relaxed state of mind.

5. Promotes aerobic metabolism and lowers blood sugar and blood lipids.

During yoga practice, muscles constantly contract and relax, increasing the amount of blood returning to the heart through the veins within the muscles. This ensures adequate blood perfusion to the muscles during practice. Combined with yoga's emphasis on breathing, this allows the practitioner's muscles to receive sufficient oxygen for aerobic metabolism. The energy source in yoga primarily comes from the aerobic oxidation of fatty acids and blood sugar. Due to the long duration of the exercise and the fact that many movements are continuous and repetitive, a high energy expenditure is achieved. The ample oxygen supply ensures that aerobic oxidation proceeds effectively, thus activating solid fat in the body and reducing blood sugar and blood lipids.

(III) Yoga meditation is beneficial for weight loss.

Meditation may seem to have little effect on weight loss, but it actually has some more remarkable characteristics. These are mainly reflected in the following points.

1. Improves nervous system function and suppresses appetite.

The process of meditation requires "calmness of mind" and emphasizes "intention," both of which have a good training effect on brain activity and improve the overall function of the nervous system. This enables the body's satiety nerves to function normally, effectively suppressing appetite and reducing the possibility of obesity.

2. Reduce the body's oxygen consumption, allowing the body to enter a state of complete aerobic metabolism.

When meditation reaches a certain state, it alters bodily functions. The relaxation effect of meditation is three times that of sleep. When a person is completely relaxed and resting, their breathing rate decreases, blood pressure drops, and blood oxygen saturation (the blood's ability to carry oxygen) increases to three times its normal level. The body's oxygen consumption decreases, putting the body in a state of complete aerobic metabolism, accelerating calorie consumption and fat breakdown.

3. Triggers human hibernation genes and promotes fat breakdown.

When people meditate, they can achieve complete relaxation, allowing the brain and internal organs to enter a resting state. This can trigger hibernation genes in the body, leading to the consumption of body fat and energy. Many animals, such as bears and snakes, hibernate. Hibernation is a physiological response to adapt to changes in the external environment and ensure their survival. During hibernation, they consume a large amount of fat. Because they do not eat during hibernation, they consume almost no sugar; fat breakdown provides almost all their energy.

(iv) Yoga's dietary requirements are beneficial for weight loss.

The dietary requirements of yoga are very beneficial for weight loss.

First, yoga promotes a vegetarian diet, minimizing or eliminating meat consumption and emphasizing whole foods, including fresh vegetables, fruits, grains, soy products, and milk. It also requires drinking eight glasses of quality water daily and avoiding or minimizing spicy or stimulating foods. This makes it easy to achieve a balanced calorie intake, and combined with the calorie expenditure from yoga postures, it helps achieve weight loss.

Secondly, the intestinal cleansing and fasting methods in yoga are unique ways to reduce body fat and eliminate toxins. These methods can result in a weight loss of 3-5 pounds within 2-3 days. However, this is not a simple starvation or hunger-based weight loss method; rather, it reduces the accumulation of toxins in the intestines. Regular practice can not only help with weight loss but also improve overall health. However, this method must be performed under the guidance of a professional.

Third, the dietary approach advocated by yoga is key to maintaining good weight loss results. Yoga's dietary approach doesn't encourage restrictive eating, but rather promotes eating smaller, more frequent meals and chewing slowly. Because yoga practice puts the body in a relaxed and peaceful state, it fosters a gentler, calmer temperament, thus preventing overeating. As long as people persist in practicing yoga, they will find their eating habits gradually becoming healthier, thus ensuring that their weight loss results don't rebound.
