protein

The limits here are really just a guide. I personally find it incredibly difficult to stay under all the limits because what might be high in protein is low in cal's and vice versa for a lot of the nutrition ideals. By far, protein is one of the best to be over on simply because it will make you feel fuller and your body will digest it a lot slower (and has to work harder to do so). Protein is also fabulous after workouts which is why a lot of people opt for this as a snack alternative (or occassionally even a meal alternative). I really enjoy my protein shakes because they give me a lot more energy than some of the snacks I used to consume. There are many many different brands available and GNC is one of the best places to purchase it. Iso-Whey is a great quality protein and it usually comes in some decent flavors so it's not a chore to drink (although some people will tell you it takes some getting used to). If you are a Vegetarian or Vegan, you can purchase alternative stuff at Wholefoods or any Natural Grocery store. Because I have allergies, I usually buy a vegan brand which I love.

It's a personal choice (not everybody wants to drink protein shakes), different brands suit different people. It's not mandatory but a good way to fill yourself up and make your body work that little bit harder.

Good luck.

I looked up protein because I too constantly go over. Protein-heavy foods are the only thing keeping me on-plan at 1260 calories a day. While you should of course consult a doctor, unless you have certain problems (kidneys are the one I remember) it's very very hard to overdose on protein.

For my plan, Fat, carbs, calories cholesterol are all hard limits. So's sugar, but I'm struggling with that one. Protein, fiber, and vitamins, I take those as suggestions.

If you're trying to gain weight, try smoothies made with yogurt, fresh fruit, and soy protein powder!
