Nutrition is a very important part of staying shape, one may even argue it is the, most important part. I know everyone has seen the people that go in the gym day after day, and their body never changes. The problem with most of these people is their eating habits; for instance, the kinds of food they eat, how many times they eat a day, and the size of their meals. One of the most common mistakes of a person, just starting to working out (mostly, bodybuilding) is that they eat too much, and don't proportion meals properly, causing most newbies to gain too much fat. This technique of just stuffing your face with what ever you can get your hands, ultimately results in a bloaded look. usually, you will have to Cut down and start over again, wasting all the clean gains you could have had, if you would have followed a few basic eating rules.
