3) Switch from regular soda to diet soda. One can of regular soda has 155 calories and 40 grams of carbohydrates. That is equivalent to almost three slices of white bread! In comparison, diet soda has no calories or carbohydrates. If your spouse or roommate likes regular soda, make sure to have diet soda available for yourself.

4) Add a fiber supplement to provide additional fiber. Mix a fiber powder into foods like cereal, oatmeal and yogurt. Each teaspoon adds fiber, which will help you feel full longer and less tempted to snack when you see others reach for a treat.

5) Not all metabolisms are created equal. Ever notice that if you try to eat the same way your guy eats, you gain weight and he doesn't? That is because men naturally have more muscle mass than women do, so they have faster metabolisms. Therefore, if you are eating the same foods and quantities as your husband or boyfriend, you are going to gain weight. Recognize this and stick to your diet, and if you're going to order the same dish as your guy, always make sure to eat a smaller portion.

6) Ask for support. Making your spouse, best friend and family members aware of your dieting efforts will help keep you on track. Your mom will stop pressuring you to try her homemade chocolate cake and your husband may even offer to trade in a pizza dinner for a healthier meal.

7) Switch to whole-wheat products. Buy whole-wheat bread, wraps and pastas. These products taste just as good as the white varieties but contain fiber and whole grains. Also, buy high-fiber cereals. These are great snacks to mix into yogurt or cottage cheese and even add as a topping to a small cup of low-fat frozen yogurt.
