The best way to lose weight is by consuming fewer calories than you expend or conversely, by expending more calories than you consume. Experts have discovered that certain foods can actually help you to lose weight without the stress of dieting or exercise. The down side is that many of us have a tendency to dress these foods up with cheese, sour cream, butter or other calorie-laden flavor enhancers. This causes the weight loss effect to be lost. It may be difficult to not add extra calories to these foods but with a strong will power it can be done. A negative calorie food can be defined as a food that results in a slimming effect for the body. In other words a carrot (without anything else) will cause your body to use an increased amount of energy when digesting it and other foods, this can lead to an overall reducing effect on the body. This is partly from the amount of energy it takes to digest the carrot or other negative calorie food and partly from the elevation in metabolism that these foods naturally create. The overall effect is a net loss of energy, which is measured in calories. It should be understood that �negative calorie’ doesn’t mean that the food has zero calories in it, nor does it have an anti-calorie or a negative calorie. Here is a partial list of negative calorie foods: apples, cranberries, grapefruit, lemon mango, oranges, pineapple, raspberries, strawberries, tangerines, asparagus, beets, cabbage (green), carrots, cauliflower, hot Chile peppers, cucumbers, endives, garden cress, garlic, green beans, lettuce, onion, papaya, radishes, spinach, turnips and zucchini. There are more and you can learn about them from a medical doctor’s very popular book. In his book, Foods that Cause You to Lose Weight, Dr. Neal Barnard explains the effects these foods have on the body. A quote from Dr. Barnard’s book reveals some startling facts, "They found that those who ate foods that were very low in fat and high in carbohydrates, lost weight steadily, without limiting how much they ate. But those on high-fat diets could not effectively lose weight even if they ate skimpy portions." Dr. Barnard is referring to the published results of an experiment conducted at Cornell University and published in the May 1991 edition of the American Journal of Clinical Nutrition. A book reviewer posted on a website how he lost 30 lbs. utilizing the information from Dr Barnard’s book. It is important to exercise caution when dieting because there are certain things that your body needs to remain healthy including proteins, fats, vitamins, minerals and other nutrients that are necessary for the body to function at its optimum level. You cannot remain optimally healthy by eating the negative calorie foods alone. This article is for information purposes only and is not meant to diagnose, treat or prevent any health condition.
