Sugar-Free Cookies and Candy
"No sugar" must mean fewer calories--or at least that's what the manufacturers want you to think! But most sugar-free brands have as many calories as the regular kind. And too much of the sugar alcohols used to sweeten these products can cause loose stools, diarrhea, and cramping. So indulge in the full-sugar brands; just do so in moderation.
Nutritional Energy Drinks
The body derives energy from calories, so (surprise!) that's what these shakes deliver: 240 extra calories a day, enough to make you gain 1/2 lb a week. Take a daily multivitamin to get the vitamins without the spare tire, and have a real milkshake once in a while.
Complete Salad Kits
Salad-in-a-bag has been a lifesaver in many a busy mom's kitchen, but they can pack a caloric wallop: 510 calories and 45 g of fat in one package of Dole Caesar Salad Kit. Buy the light variety instead, or add your own low-fat or fat-free dressing at home.
Vegetable Pizza-for-One
The veggies are healthy, all right. But the gobs and gobs of cheese they're sitting on aren't; they're full of artery-clogging saturated fat. Look for low-fat versions, and be sure to check the saturated fat content so you can compensate elsewhere in your daily intake.
