guys usually think they can eat anything they want without gaining weight. They believe they can eat junk food all day because they have a fast metabolism. Some think they can’t gain weight because they don’t digest the food they eat, are stressed out, or “have worms”…

Here’s the truth: you can eat everything you want without gaining weight because you don’t eat a lot. I know you think you do, but you don’t – otherwise you wouldn’t be skinny. Really.

Track your daily caloric intake for proof. Spend the next week logging everything you eat in an app like myfitnesspal. You’ll see you’re not eating that many calories. This is the main reason why you’re not gaining weight. Skinny men always overestimate how much they eat.

This doesn’t mean a high metabolism doesn’t exist. Some people have a harder time gaining weight because they’re more active (hardgainers tend to fidget more). Others are naturally skinny because they have small frames and thus aren’t born to be big and strong (ectomorphs).

But every skinny guy, hardgainer and ectomorph who eats more calories than he burns gains weight. It doesn’t matter if you have a high metabolism, skinny build, or bad genetics. The only difference is that you’ll need to eat more food than the average person to put on weight and get bigger.
