It seems logical that, when you follow a diet to get rid of a few pounds, you just look at the shelves with low-fat products or fat free from grocery stores. Nutritionists warn that when we try to lose weight by eliminating fat from the diet, the result will be null in terms of inches, with an increase of heart disease risk. People who eat only low-fat food will never lose weight explain the specialists, as these figures are not the key to dream body, but a trap.
According to a study published in the Journal of the American Medical Association, researchers from the New Balance Foundation Obesity Prevention Center in Boston found that fat in the diet has a role in the metabolism and even maintains your body shape and health.
For four weeks, scientists have observed several groups of people who followed different type of diets. People in the first group tried to lose weight by eliminating the fat from their diet, the second group eliminated carbohydrates from their diet and the third group was on a diet with a low glycemic index.
While in the first group fat was found in 20% of total daily calories, in the third group fat was found in 40% of calories.
The second group cut the carbohydrates which reached only 10% of total food consumed daily, while in the third group carbohydrates represented 40% of the daily food intake. All three groups had the same number of calories each day for 4 weeks.
The results? Amazingly, people in the group that removed the fat from their daily food burned the fewest calories. Even more, because of the fact that good cholesterol level decreased with the bed cholesterol level, they were at risk of heart disease to a greater extent than those in the other two groups.
People who have given up carbohydrates managed to burn 300 calories a day more than people in the first group, but the dietary imbalance has created an increased level of hydrocortisone in the body, a steroid hormone. In addition there was an increased risk of heart disease and diabetes.
By far, the most efficient plan of losing weight proved to be the one based on the glycemic index. Foods with a low GI (glycemic index is an indicator that measures the speed at which a particular type of carbohydrate reach the blood and influence the blood sugar levels) help losing weight, not the fastest way, but certainly the healthiest.
People who follow such a diet burned daily 150 calories more than those in the group that removed fat from their diet, but without any health risk. In the case of the glycemic index diet, there was no abnormal functioning of the body, as in the case of the other two diet types examined.
Basically, it isn’t the elimination of fat in the diet that causes the weight loss and a better health, but the consumption of food with a low glycemic index, that is, the foods which are slowly digested, such as beans or other vegetables that don’t contain starch such as cauliflower, broccoli, etc.
