How many times has Dr. Kahn heard in his clinic "I work out most days so give me some slack on my diet". Can you really count on your gym time to act as an antidote to fried foods, fast foods, and sweets?   This week, Dr. Kahn discussed two studies, one of which reports that the optimal health plan is a great diet with great exercise commitments. The second study sets a new bar of how much exercise is optimal for the lowest risk of death from any cause.   Dr. Kahn has a special offer at walkitask.com for an easy-to-use adjustable desk for a treadmill you might have at home and the discount code to save a bundle is Doc35.
