Exercise before breakfast?

Fascinating article about exercising before or after breakfast. The experiment was relatively complex, but the end result was that all other things being equal, when consuming a high-fat, high-calorie diet only those who exercised before breakfast did not gain weight and did not exhibit insulin resistance.

Unfortunately I don't have enough data points for exercising before breakfast vs. after to be sure, but there is some evidence that I did, as a general rule, lose more weight when I exercised before breakfast. Interesting!
