Insulin is an anabolic agent. Insulin helps in the absorption of nutrients. The muscle cells absorb more glucose which is later stored as glycogen whereas the fat cells take in lipids releasing more amount of insulin. Lower levels of insulin result in a body with lower fat composition.
Your diet program should consist of a low carbohydrate with high fat and protein intake for five days in a week. The last two days should have the opposite, that is, high carbohydrate with low fat content. The days when you have low carbohydrate intake show low insulin release with the body being forced to reach a catabolic state where it is able to work more efficiently in burning fatty acids to produce energy.
