The human body and its consumption of food for energy are identical with a steam engine, which works by burning fuel. The human body works by food with the only difference is the humans have the tendency to store the excess fuel and deposit it by converting into fat, resulting in obesity. The obese in Ayurveda literature are described as, imbalanced and prone to a number of diseases. Kapha dosha is responsible for the material stuff of the body. This includes all the heavy tissue except the bones and blood, the adipose tissue, the muscular tissue, the bone marrow, and all other body fluids like the lymph and shukra. Except for these all heavy tissues are kapha category.
