Many health experts recommend that people on a diet eat as much lean protein as possible. Why? Because protein helps you feel full, thereby curbing the desire to binge on unhealthy foods—such as those high in sugar, calories or fat—later on. On the surface, protein bars fit the bill.
But here’s the problem: many protein bars are full of calories, fat and sugar. That makes the appropriate for people who engage in intense bouts of exercise (such as athletes) but means they’re probably not the best food choice for a normal person trying to lose weight. If you really like protein bars, look for ones that don’t overdo it on the sugar, fat, and calories.
