Avoid cutting calories, but do not consume too much. Healthy and active adults need approximately 2,000 calories a day. The more exercise you do, the more calories you need. Use a daily calorie calculator (see Resources section below) to determine how many calories you need each day.
Add fruits and vegetables to every meal, and even to snacks. For example, add bananas to your cereal at breakfast, eat a salad and an apple with lunch and have tomatoes and canned peaches with your dinner. This can help you get the recommended three to five (or more) servings of fruits and vegetables.
Try new foods. Make an effort to pick out something new at the grocery store every week. Browse the produce section and choose a fruit you have never had before. This can help give you a healthier, more balanced diet so you're not eating the same things all the time.
Check your portions. More appropriate portions can make a huge difference. One way to check portions is to read the nutrition label and see the recommended serving size. (See the link in the Resources section below for appropriate portions.)
Cut out excess sugars, salts, caffeine and alcohol. These (in excess) are toxic to the body and will deplete nutrients. Eat a healthy well balanced diet and enjoy your foods and drinks containing these toxins in moderation only, or cut them out altogether.
Clean your home of junk food. If it isn't there you are less likely to eat it, especially at nighttime. When you are able to cut out junk foods (sugary, salty snacks) you will eat what is available in your home, which should be healthy choices such as fruits, vegetables, pretzels, and crackers.
Balance your diet with proteins and carbohydrates. Include meats, beans and fish for protein. Avoid cutting out carbohydrates, as you need these for energy. Fruits, vegetables, whole grains and pasta contain needed carbohydrates.
