Eat the right stuff at lunch, and you can cancel those desperate 3 p.m. coffee runs. The building blocks: minimally processed carbohydrates (whole wheat bread, whole-grain crackers, wheat pasta, brown rice or bulgur). Protein (lean chicken, or turkey breast, low-fat or fat-free cheese, canned tuna, or salmon). Any fruit and/or any vegetable and low fat diary.

No candybars as a snack?
