What is lipolysis?
Lipids are fats. Lipolysis is a mechanism by which the lipids are broken down in the body and leads to the generation of 9 calories. There is an enzyme called lipoprotein lipase, which leads to lipolysis in most of the cells.

What is lipogenesis?
Whenever we have taken excessive calorie in our food in the form of carbohydrates or proteins, these excess calories are also converted into fats. The process of formation of fatty acids from glucose to dietary carbohydrate is called lipogenesis.

What is thermogenesis?
Thermogenesis is the process by which the body generates heat, or energy, by increasing the metabolic rate above normal. This rise in metabolic response, or specific dynamic action (SDA).
Thermogenesis is activated, by a few different mechanisms, including supplements, nutrition, excursion and exposure to cold. Among the nutritional activators, the various macronutrients have different effects on the thermogenic response. When you ingest food, your metabolic rate increase above the fasting level. In the case of protein, energy is used to process the protein, which is then used for tissue growth and repair. On the other hand, carbohydrates and fat function primarily as fuel and are used more efficiently as such by the body. Carbohydrates and fat, therefore, have a much lower thermogenic effect than protein.
