Ask anyone how to burn fat or lose weight and the answer is often: fewer carbs, more exercise. Of course, that may be all well and good for a quick fix, but when it comes to something sustainable and healthy, complex carbs such as sweet potatoes, bananas, beans and brown rice are imperative. There are a few things to look out for when it comes to determining how much of the starchy stuff you should be noshing on. 1) Fatigue Are you constantly tired? Carbs, please. 2) Dehydration Do you struggle with headaches? Carbs will help you absorb and retain water. 3) Colds Kleenex taken over Kiehl’s in your make-up bag?
