>you could eat nothing bit chips and candy and be perfectly healthy

no one said that you'd be HEALTHY if you ate nothing but chips and candy. what was said was that you could still be skinny eating just that as long as you didn't eat too much of it. you can eat below your calorie limit with just junk and be skinny, or you could eat nothing but an excess of organic produce and product that blows your calorie limit and still get fat

healthy food =/= automatically skinny. the calories in those healthy foods still count

that was the point
