I've been commenting on so many of these lame research efforts lately that I probably ought to come up with a regular "grants I should have applied for" feature:
Exercise may be especially helpful in reducing the size of fat cells around the waistline -- more so than diet alone, a study suggests. That's important, because fat specifically in the abdomen has been linked to the risk of heart disease and diabetes.
Whoda thunk? I bet if they study really, really hard and spend enough money, they'll discover that a combination of diet and exercise would be best for fat cells in places besides the waistline.
