There’s a new twist in fat burning, exercise and food timing. While some promote exercising fasted to maximize fat burning, manipulating fuel use during training may not contribute as much to fat loss as you might think.
Realize that the fuel burned during exercise is only part of the weight loss equation. The twist comes in, however, when we consider what happens during the rest of the day, after exercise. That’s just what a group of researchers from Italy investigated. They compared the all-day effects of exercise performed either fasted or fed (after breakfast) using everyday people (as opposed to elite athletes). They tested the effects on the athlete’s fuel utilization at 12 and 24 hours after a 36 minute exercise session keeping to a moderately-low intensity level (65% HRmax). The athletes in the group that had breakfast burned more fat at 12 and 24 hours post-exercise than the athletes training without food beforehand.
