These are the body types. Now something like 70% of men are Mesomorphs -- which means you can get fat and lose fat quickly. Endomorphs lose it slower...but mostly that last 30 lbs is a bitch for these poor guys. The trade off is they can get huge.
Something like 20% of motherfuckers out there -- that's 1 out of 5. Never ever has to worry about gaining weight. They tell these guys NOT to do cardo...it will ruin their strength training. And that's the trade off -- these poor guys have a hard time getting muscle.
Basically, there are too many god damn Ectomorphs out there, giving advice on how to stay thin to people that are mesomorphs and endomorphs...same with the bodybuilding world...too many Endomorphs explaining to ectomorphs how to get huge.
So that's where body type comes in the conversation. Basically you need to separate the problems ectomorphs have from Mesomorph and Endomorph. But even if you are Endomorph and lose slower...same diet same concept same results...slightly longer time frame.
