The first medical treatment for obesity in Ayurveda is the Skipping or Fasting. It is the illusion among people about the skipping that they lose their energy due to skipping, but there is nothing like that. If fasting is done properly then nobody is weak. The right way to fast is that if we have to eat three times a day, then one can leave the meal once. You can live only by eating Khichadi or by drinking juice.
The main reason for obesity is acids, which we should use acid digestive drugs to remove. Such as Trikuta, Triphala, Hingwashak Powder, and Avipattikar Churna Powder. The best medicine described for acid digestion in our Ayurveda is hot water, we should also intake warm water.
