Foods with large amounts of calories should be avoided. If you normally have high calorie foods for a meal, replace those foods with lower-calorie foods. This is especially important with toppings and ingredients as well as regular dishes. For example, if you're going to have a salad, try replacing the fatty, high-calorie salad dressing with vinegar or some kind of juice. You can also get rid of high-calorie butters and instead have tasty oils with your bread, meat and pasta. Also stay away from alcohol, which can interfere with weight loss while also containing large amounts of calories. Alcohol also dehydrates you, which is counterproductive for dieting efforts.

Snacking on unhealthy foods can be the downfall of any diet. If you are really serious about losing weight by dieting, then you should plan accordingly by surrounding yourself with healthy snacks. Try things such as nuts, fruits and finger vegetables such as baby carrots to kill those hunger pangs between meals. You should never let yourself get to the point that you feel very hungry. Rather, you should snack on enough healthy food throughout the day that you quell your raging metabolism while not packing your body with useless fats and empty calories. Remember, you need food and energy to be awake and alert, and to do the kind of exercise you need to make dieting really worthwhile.
