How does calorie restriction work and what are its benefits? Kevin Gianni from the renegade health show talks about the calorie restriction theory and the pros and cons of it. He also talks about calorie restriction in raw food and calorie and diet related issues in a raw food diet.  When I mentioned yesterday that I wanted to gain weight a sharp viewer asked me about calorie restriction and told me maybe I should be listening to that idea. If you feel that you are not having proper calories in your body, you better should start gaining some weight to remain fit. Also, you should take some digestive enzymes which will help you in proper digestion and you feel like having something to eat after every 3-4 hours.
