When it comes to bodybuilding advice about the amount of food and the type of food a body builder should eat, there is a lot of confusion out there.  To achieve a really good shape and maximum performance, you should aim to forgo the traditional three square meals a day approach to eating.  Active people must fuel themselves throughout the day, and this means they should eat frequent small meals and snacks every two to three hours.   Much research has gone into this belief, and claims are made that by eating multiple meals – four or more a day – increases “thermogenesis”, which is the production of heat by the body as it digests food and absorbs it. During this process the metabolic rate speeds up and your body processes nutrients more efficiently.
