Two studies published in the New England Journal of Medicine tried to compare both types of diets.
In the first study found that those who do low-carb diet was going to experience greater weight loss than those who use low-fat diet. Period used for the assessment is 6 months.
In addition, those who commit low-carbohydrate diets were also decreased levels of blood fats (triglycerides) are larger and also improvements in insulin sensitivity. Participants in this study are many who suffer from diabetes and had multiple risk factors for heart disease and blood vessels. But in terms of assessment of improvement in insulin sensitivity only involves those who do not suffer from diabetes.
A second study has a duration longer assessment is 12 months. Within 6 months, those using low-carbohydrate diet lost weight more meaningful than those using low-fat diet. Unfortunately, in the 12th month found that those who use low-carbohydrate diet will gain weight again and this increase was greater than those who undergo low-fat diet. As a result, the difference in the two types of these diets in weight loss becomes insignificant in a period of 12 months.
It seems polemic which includes both types of these diets will continue. Although low-carb diet seems to be the upper hand, safety factors need to be taken into account. Low-carbohydrate diet is generally done without restriction in terms of fat content and high protein. Therefore, any effects of long-term safety need further study.
It is not certain whether the low-carb is the determinant of weight loss and not a result of the low calories used. Therefore be careful with your weight loss program. Consult with a nutritionist to get the best referrals.
