Whether or not we like to admit it, genetics plays an important role in our ability to lose weight. And endomorphs have it rough. Marked by round physiques, high body fat, and a sluggish metabolism, the slightest divergence from a clean diet packs on pounds for these fellas. This makes getting lean a constant, discouraging struggle. Plus, our modern culture makes weight-gain so easy for all of us, with simple sugars and fried foods on every corner, it's like the world wants us to be overweight. If you’re an endomorph, you need to face facts: you are insulin dominant, your sympathetic nervous system is sluggish, and your carb tolerance is worse than Pavarotti’s.
You simply do not have the same genes as the skinny dude who has trouble gaining weight. But the silver lining of endomorphia is that your body can pack on lean muscle easier than “hard-gainers”. Embrace your genetics by lifting heavy weights and keeping your rest periods to a minimum in the weight room. Then follow a few simple nutrition and supplementation rules to keep your body from storing excess fat and you’ll soon look more like the Jonah Hill from 21 Jump Street instead of the Jonah Hill from Moneyball.
