Weight normalization is one of many benefits of Bikram Yoga. As a beginner, it takes about 3 classes for your body to understand the proper approach to the postures. During the next 10 classes, digestion and respiration, as well as endocrine, lymphatic and elimination systems will begin to work harmoniously. Your appetite will normalize and unhealthy cravings will diminish. All of these results will help to normalize your weight if you devote yourself to regular practice at least, but preferably more than, 3 times per week.
