Chromium increases your cell's sensitivity to insulin and is depleted by refined sugars, white flour, and lack of exercise. One study showed users lost 4 pounds over 10 weeks compared to no pounds from a control group.
Though the studies aren't definitive at this point, I recommend the supplement for waist—and blood sugar—control. You should take it with magnesium, which reduces low-grade inflammation that can be associated with insulin resistance. A dose of 600 micrograms of chromium has been shown to be effective for those with Type 2 diabetes, but for others, stick to the recommended dose of 200 micrograms. Just because a little is good doesn't mean taking a lot more is better. Taking too much chromium can hurt your kidneys.
