Ignore fad diets. Carbs and fat are not evil. Even cholesterol is necessary for creating cell membranes. Keep a food diary to keep track of your eating and figure out which foods you're lacking. Are you getting fruits, vegetables, whole grains, low-fat dairy, and lean protein into your meals every day?
Eat unprocessed foods.
Preserving food involves adding things that help the food last longer and help it taste better at the expense of nutrition. For example, a cup of strawberries has about 50 calories, and provides 150% of your daily vitamin C requirement, but a cup of strawberry jam has 375 calories and no vitamin C. Always look at the back of the package. If the ingredient list takes over a half-inch of space, you probably shouldn't be eating it.
Eat reasonable portions.
You may know what's in a cup of cereal, but how many cups of that cereal are you pouring into your bowl every morning? Start measuring everything you eat so you can get a grasp on just how much you're eating. If you eat out a lot, look up restaurant websites. Here you can use nutritional information to plan your meals ahead of time.
It takes 3,500 excess calories to create an extra pound of fat. To gain one pound in a year, you only need to eat ten excess calories a day: that's just over half a teaspoon of sugar.
