An article about the pitfalls of using mice for animal research leads off with the example of calorie restriction. The controls for calorie restriction mice experiments were obese mice, suggesting that the health benefits of calorie restriction might be conflated with the health benefits of not being obese. I get the impression that people who study calorie restriction still think it worthwhile for life extension, but it’s useful to try and integrate all evidence you come across.
[edit] timtyler suggests this is a well-understood effect that’s already been taken into account by CR scientists.
