What Is The Best System Dietary Weight Loss?
The dramatic increase in obesity in the world urgently requires studies to test the
effectiveness and safety of diets to lose weight more widely used.
Diets low in carbohydrates, high protein, high fat (referred to as low in carbohydrates) have been compared with diets low in fat, energy restricted. A meta-analysis of 5 studies with 447 participants and a recent one-year study involving 311 obese women suggest that a low carbohydrate diet is a viable alternative to a diet low in fat for weight loss and may have favorable metabolic effects. However, long-term studies are inadequate. A Mediterranean diet with a moderate amount of fat a high proportion of monounsaturated fats provides cardiovascular benefits. A recent review of several studies suggests that the Mediterranean diet was beneficial for weight loss. However, this positive effect has not been demonstrated.
The common limitations of dietary studies include high dropout rate (15 to 50% within one year), small size, short duration, lacking evaluation of adherence, and differences in the intensity of intervention.
Shai I. et al. DIRECT conducted the study (Dietary Intervention Randomized Controlled Trial) to 2 years to compare the effectiveness and nutritional safety of three protocols: one low-fat, calorie-restricted diet, a Mediterranean diet restricted in calories and low in carbohydrates, unrestricted-calorie diet.
Randomized 322 moderately obese subjects (average age 52 years, mean body mass index, 31, male, 86%) to one of three diets: low fat, restricted calorie, Mediterranean, restricted calorie; or low-carb, unrestricted-calorie diet.

3. Low-carb diet: no calorie-restricted diet, consisting of 20 g / d of carbohydrates per 2-month induction phase with a gradual increase up to 120 g / d to maintain weight loss. The total intake of calories, proteins and fats without limits, but with tips for choosing vegetable sources of fat and protein and avoid trans fats.
The percentage of adherence to the diet of the study was 95.4% annually and 84.6% at 2 years. The Mediterranean diet group consumed the greatest amount of dietary fibers and showed the highest ratio of monounsaturated and saturated fat (P
