Short spoken argument by Jim Katsoulis asserting that calories from different foods affect satiety and subsequent intake differently. He contrasts 100 calories from an apple versus 100 calories from cookies, claiming the apple satisfies while the cookies provoke further eating, so equal calories can have different effects on weight-loss behavior.

A calorie is not a calorie when it comes to losing weight. Let me give you an example. If you eat 100 calories of Apple versus 100 calories of cookie, the 100 calories of Apple, you're going to finish it and you're not going to want to eat another apple. You're going to eat 100 calories of cookies, and you're going to want to eat more cookies. And so, yes, if you only ate 100 calories of each, it doesn't matter. But the hundred calories of cookies is going to cause you to want to eat a lot more calories.
