Yep. We have McDonald's once a week, and my normal dinner there--burger and fries, take the top bun off the burger--is 490 calories. It is disgustingly easy to maintain a decent weight while still having fast food and/or treats; it's just fats are too dumb to do math and too greedy to stop eating at one burger and one order of fries, and instead will keep shoveling it in until they feel ready to explode (and then start shoveling it in again the moment they start to feel normal again).
