Bars
 

The problem with most bars—be it snack, protein, or energy—is all the added sugars and fats. Obviously protein bars are calorie-dense to help you gain muscle, but if you’re chowing down on ‘em after a light workout, or eating them even if you haven’t worked out, it can easily pack on the pounds. Likewise, nutrition and snack bars tend to be saturated fat and sugar bombs with add-ins like nuts, dried fruit, and chocolate. You want to opt for bars with minimal, pronounceable ingredients.
