Body weight Studies have shown that the effectiveness of<unk> s for weight loss is broadly similar to that of low-carbohydrate diets in the long-term. A scientific panel for the Endocrine Society stated that "when calorie intake is held constant ... body-fat accumulation does not appear to be affected by even very pronounced changes in the amount of<unk>  vs carbohydrate in the diet." Cardiovascular health<unk> s have been promoted for the prevention of heart disease. Lowering<unk>  intake from 35-40% of total calories to 15-20% of total calories has been shown to decrease total and LDL cholesterol by 10 to 20%; however, most of this decrease is due to a reduction in saturated<unk>  intake. Saturated<unk>  has been shown to raise total and LDL cholesterol in a large number of studies and has also been correlated with a higher risk of heart disease. A 2013 meta-analysis of low- and high-fat diets showed<unk> s decreased total cholesterol and LDL, but these decreases were not found when only considering low-calorie diets. It also showed HDL increases and triglyceride decreases in high-fat diets. Furthermore, lower total cholesterol was associated with lower intake of saturated<unk>  and higher intake of polyunsaturated<unk> , HDL increases were associated with high monounsaturated<unk>  intake and triglycerides associated with high carbohydrate intake. Decrease in saturated<unk>  intake was only marginally related to decrease in LDL cholesterol. The meta-analysis concluded that neither high-fat nor<unk> s could be unequivocally recommended. Testosterone There is limited evidence that<unk> s compared to high-fat diets, decreased men's total and free testosterone levels. The decrease in testosterone on<unk> s is thought to be due to a decrease in testicular testosterone synthesis, since both urinary testosterone and dihydrotestosterone also decrease on<unk> s. This indicates reduced androgen production, rather than increased androgen excretion on<unk> s.
