CHROMIUM CURBS CARB CRAVINGS
If you are like a lot of people, you might have a compelling and recurring hunger for carbohydrate-rich foods. Cravings for starchy and sugar-laden foods are common and the underlying biological process may operate using similar mechanisms involved for opiates and the pain/pleasure center of the brain. To some extent, cravings for carbs are like an addiction. The good news is that you may be able to beat your biology. Researchers report that simply taking 600 micrograms of the essential mineral chromium as chromium picolinate for 8 weeks significantly reduced carbohydrate cravings in a group of subjects with atypical depression. The subjects who had the most severe carb cravings experienced the best results. When blood sugar is low, you seek out sugars and starches. Although not addressed in this study, chromium supplementation may have helped to stabilize blood sugar levels and diminish the desire for carbohydrate-laden foods.

I've been taking 200mg Chromium daily for a good few weeks now and I don't think it does anything. I wouldn't fancy upping my dosage to 600mg either...

see chromium is only useful if you are sort of it naturally, and it also aids insulin release....but if you have enough the overall gain is very little
