The following is a brief overview of how each of these minerals help lead to weight reduction.
There is much discussion about the role of calcium in weight loss and body fat reduction. Several studies have indicated that calcium plays a role in body weight regulation and especially fat metabolism: Lowering cholesterol and especially LDL cholesterol. A key study found that an increase in dietary calcium intake, together with normal protein intake, resulted in an increase in fecal fat and energy excretion by 350 calories per day (Int. J. Obes. Relat Metab Disord:2005, Jan.18). Additional studies have shown that a dietary intake of calcium in the range of 1000 to 1500 mg of calcium per day (especially in dairy products) has impact on fat metabolism through impacting lipolysis, lipogenesis, energy expenditure and appetite suppression. In fact, these studies indicate that a high calcium diet helps prevent lost body weight and lost body fat from coming back.
In recent years, chromium has been clinically demonstrated to augment the action of insulin. This finding concurs with studies showing that long term use of chromium effectively controls blood sugar in people known to be carbohydrate intolerant. Time and again research has indicated that keeping blood sugar under control can lead to an increase in weight loss and a reduction in body fat. Inadequate chromium results in insulin resistance, causing blood sugar fluctuations, subsequent hunger cravings and binge eating. Although the exact role of chromium has been difficult to pin down, recent findings indicate that chromium has a part in insulin signaling. Poor insulin signaling or insulin resistance is a prevalent finding in those suffering from obesity.
