Snacks are great to have as they keep your blood sugar levels even. If you eat a big breakfast and then don’t eat for a while your sugar levels will drop down and then spike back up again when you eat another large meal at lunch. That is why snacks are so good. They help keep you going till your next meal and you won’t be as starving by the time you eat lunch. So you will probably eat less at lunch as well. Just be sure you are snacking on healthy foods. You want high fiber, high protein, and good complex carb snacks. They shouldn’t be large. Snacks are small, remember that.
