Dear Doctor: I hate dieting and have been putting off losing these last 12 pounds of baby weight. My husband says I should at least start exercising because it makes your fat healthier. Can this really be true?
Dear Reader: For all the bad press the fat within our bodies receives, it’s actually a vital resource. With more than double the calories per gram than proteins or carbohydrates, it’s an efficient system for storing energy that helped our ancient (and not-so-ancient) ancestors survive uncertain times. And while we tend to think of body fat in terms of its physical manifestation, as in the bulge of a waistline, it’s actually a dynamic nutrient with multiple forms and functions within our bodies.
