foods that occur naturally have zero calories. However, food companies have engineered some products to have zero calories, and many people believe that other foods actually create a calorie deficit when your body gets done digesting them.

Truly Zero-Calorie Foods

The only truly zero-calorie foods are water and diet soda. Water is the only true zero-calorie food that occurs naturally.

Water and Dieting

Dieticians recommend eight 12-ounce servings of water every day as a healthy part of any diet. Water also has an added benefit when youíre trying to diet to lose weight: it helps fill you up. You can freeze water into ice and crush or shave it in order to add a different, zero-calorie texture to your diet.

Dieting with Diet Soda

Diet soda pop is available in zero-calorie versions. It comes in name brands and generics and is typically sweetened with artificial sweeteners. Quite a bit of debate surrounds these beverages and whether they are healthy additions to your diet because of the artificial sweetener. Experts offer conflicting claims that artificial sweeteners cause health problems or contribute to obesity, and some studies show that diet soda may actually contribute to weight gain.

Negative-Calorie Foods

There are several fruits and vegetables that occur in nature that, while they have calories when consumed, may actually result in negative calories or a calorie deficit after being digested. According to this theory, these foods cause the body to expend more calories to digest the food than are contained in the nutritional content. The result would make them zero-calorie foods after digestion. While there is no scientific evidence that this is true, it is theoretically possible that this phenomenon can exist.

If you believe this theory, then you can consume these foods without feeling guilty. They are healthy and provide nutritional content your body needs, but they do contain calories. Keep in mind, also, that even according to this zero-calorie theory, these foods only have this negative calorie effect when consumed without extras added to them like butter, sugar or dips.

Eat Healthy

Any time you go on a diet, itís advisable to consult your doctor first. That way you can receive an expert opinion based on your medical history and health conditions.
Even though you are attempting to lose weight, itís still important to maintain a certain number of calories in your diet. Typically, a normal, healthy diet consists of approximately 1,200 calories for an average-sized woman and 1,500 a day for men. A diet that consists of too few calories will put your body at risk. You wonít receive enough vitamins, minerals and nutrients on a diet that consists of too few calories. Additionally, a diet that consists of too few calories wonít give your body enough energy to go through day-to-day life, making you more susceptible to illness.

Moderation is Key

Dieting can be a difficult task, and eating wisely does not include starving yourself or falling for gimmicks like zero-calorie foods. Eating in moderation, whether the food is on the zero-calorie list or not, is a key part of losing weight.
