Compared with the starch-based and low-fat diets, the high-fiber vegetable diet resulted in the largest reduction in low-density lipoprotein (LDL, the "bad" kind) cholesterol.

When we are eating excess amounts of carbohydrates (sugars), liver converts the carbon compounds from sugar into fatty acid, and then fat.

If we continue to consume too much of sugars, complex or simple, and to accumulate fat, especially in the waist area, we can develop insulin resistance.

High-fat diets and low physical activity levels may accentuate the susceptibility to obesity by the FTO variant. The fat mass and obesity-associated gene (FTO) has been shown to be associated with obesity and to influence appetite regulation.
