Hunger is a scary thing to your body.
1. It slows down your metabolism so more fat is accumulated in cells. Whatever you eat, it does not digest the way it should be.
2. It causes so-called insulin spike. It's a condition when much insulin is thrown-in. If during a spike you try to eat something (and after starving you want to eat a lot), all the food is transformed into fats, not energy.
Therefore, a balanced diet is your only key to a successful weight loss. Not work outs, no starvation, but your food.
It's some kind of paradox, but
to lose weight, you need to eat.
