Going after weight gain by going on a diet is like walking into a gunfight with a sharp stick. You might make a little dent, but in the end, you'll do yourself more harm than good.
Here's why: Typical diets restrict calories, and that means lowering your metabolism—the calorie furnace in your body that determines longterm weight loss. Going on a diet sends a signal to your body that says "I'm starving here!" And your body responds by slowing your metabolic rate in order to hold on to existing energy stores.
What's worse, if the food shortage (meaning your crash diet) continues, you'll begin burning muscle tissue, which just gives your enemy, visceral fat, a greater advantage. Your metabolism drops even more, and fat goes on to claim even more territory.
