You will lose more weight if you eat three 70-calorie eggs instead of a candy bar, even if the calorie count is the same. The eggs will regulate insulin and not cause your blood sugar to spike. The extra protein will also help keep you feel full longer. The candy bar will do the exact opposite and can cause you to pack on the pounds. It’s not just calories in and calories out, it’s the kind of calories you put in and how your body processes them that helps you reach your weight-loss goals..
