Fasted aerobics training drops weight and body fat, while fed aerobics only lowers bodyweight.
Only 19 people? Did they control for what those people ate and not just when they ate it? Did the control for the type of aerobic activity they did? It doesn't seem like they could make any reliable conclusions without considering at LEAST those confounding factors. The whole study isn't on the site so I won't believe it for now.
