Anthocyanidins

10 heavyweights for weight management #4

Anthocyanidins: These are found in grape seed, cinnamon, purple corn, berries and cherries, as well as other fruits and vegetables and are all iron-controlling molecules that inhibit the formation of fat within fat cells as well as have a great potential for the prevention of diabesity.14
It is not surprising to find that whole fruit powder from strawberries and blueberries had no effect upon weight gain, body weight or body fat when consumed with a low-fat diet, but consumption of purified anthocyanin extracts from strawberries and blueberries produced 13-34 per cent less body-weight gain in animals. The fruit extracts contain higher amounts of anthocyanins and less fruit sugar.15

While the weight-loss drug orlistat inhibits lipase, the fat-breakdown enzyme, so does grape seed extract, which may prove to be a safe weight-control agent. Overproduction of lipase reduces HDL cholesterol. Higher lipase activity is associated with greater abdominal fat and greater body mass.16

10 heavyweights for weight management #2

Calcium/Vitamin D: A revolution in the understanding of the need for vitamin D, both from natural sunlight and dietary supplements, is now under way. Vitamin D has profound and broad influence over weight control and mood, which are intertwined. Consider these facts:

Overweight individuals are frequently depressed.5 It is not uncommon for overweight individuals to be placed on antidepressant drugs, which are generally known to increase weight gain.6

It is also widely observed that depression and carbohydrate craving risesin winter months, particularly in northern latitudes, when vitamin D levels are low. Increased appetite, carbohydrate craving and weight gain are more characteristic of winter than summertime depression.7

As the body mass of adults increases, their vitamin D levels are found to be lower. As vitamin D levels decline, waist size increases.8

Vitamin D also preferentially decreases abdominal fat.9 Obese individuals submitting themselves for weight-loss surgery are commonly vitamin D deficient.

Low vitamin D levels are even associated with obesity in children (74 per cent of obese children were found to be deficient in one study).10
