Scientists have discovered something about mice that may help people trying to avoid weight gain over the holiday season. Turns out that you can’t make a normal mouse overweight on regular lab chow – they automatically eat only the amount needed to maintain a healthy weight. So how do researchers studying obesity get usually normal-weight mice to become overweight? The Cafeteria Diet. When mice get access to many different high-calorie foods, they can’t seem to help but overeat.
This behavior is similar to what happens to many people faced with buffets. Fortunately, humans don’t need to resort to lab chow – we can realize the problem and learn to deal with it.
