New York City's health department has used startling imagery for its anti-obesity ads in the past, including the guy who drank the tall glass of pure fat.  Its latest effort is no different. It pairs an image of a man who lost a leg to Type 2 diabetes  with a warning about increased soda-portion sizes at fast-food places. Critics say the ad is overly sensational, and some have called it "ineffectual" and "misleading." Mayor Bloomberg, in a moment that was equal parts hilarious and awkward, defended the ads while simultaneously endorsing a Brooklyn restaurant's fried chicken,  and admitting that his own diet was "not great for [his] waistline, but that's okay." If he keeps up that attitude, he'll be in the next round of ads. Three full ads after the jump.
