>You can melt a tablespoon of butter and toss a bunch of vegetables in it, and it will taste delicious. But it only "cost" 100 extra calories, which is nothing. So go ahead and eat an extra serving of carrots, broccoli, green beans, lettuce, radishes, etc. You are extremely unlikely to get fat that way.

Yeah, but only anorectic are able to keep eating this long term. Until they get to hospital with all kinds of body damage.
