Some people seem to have a "high" metabolisms while others a "low" one...oh wait they're "big boned"! One person can eat 5 cups of white rice with dinner and not put on a pound, while others even look at the stuff and balloon up. Are people really that different? I mean after all we are 99.9% genetically identical to every human on earth, so what gives?
While everyone can achieve the weight loss or muscle gains they wish from following a good nutrition and training program, there is something to be said about a persons body type.
There are 3 different body types...an endomorph, a mesomorph, and an ectomorph. These various categories guide, through your genetics, how you tolerate specific foods.
This "fatter" build means that they generally do not tolerate carbs as well as the other two. Eating higher carbs leads to an increased fat storage and weight gain. This does not mean that they should eat no carbs, it just means that they need to eat less. Substituting some carbs with good fats will help them manage their weight easier.
Eat: increased protein, increased fat, decreased carbsbs
Mesomorphs respond best to a balanced style diet. One consisting of roughly equivalent amounts of carbs, proteins, and fats.
Eat: moderate protein, moderate carbs, and moderate fats.
This higher metabolism means that they respond best to a higher carbohydrate diet. There higher energy outputs needs to be fuelled by an increased glucose source. Don't assume that if you are a ectomorph you can sit on the couch, eat doughnuts, and not put on weight! It will catch up with you.
Eat: moderate protein, decreased fat, and increased carbs.
Think about what category you fall into. Try eating in a fashion that best suits that body type. If it is not working as well as you think then perhaps you picked to wrong category. I know for me personally I am probably about 70% mesomorph and 30% endomorphs. If I am not careful about what I am eating I can quickly add 10 pounds to and an extra belt hole around my waist.
