If you’re trying to lose weight, skipping meals is one of the worst things you can do. Your body needs a steady supply of food, which acts like fuel, to keep your metabolism running the way it should. Depriving it of healthy foods does not help weight loss. It also makes you ‘hangry’ or irritable because of hunger. When that happens, you are more likely to overeat, and when you do eat, you are more likely to eat unhealthy foods.
