In a small new study, a group of overweight men did a 60-minute walking workout before eating any breakfast and then, on a different day, did the same workout after eating a carbohydrate-rich breakfast. Based on blood and tissue samples taken before and after the two workouts, researchers believe that stored fat was used to fuel the pre-breakfast workout, whereas the recently eaten carbs fueled the after-breakfast workout. This was a small study, but other research supports the notion that pre-breakfast exercise is especially beneficial for weight loss. To get into the morning-exercise habit, lay out your exercise clothes and shoes the night before (the more time you spend looking for your T-shirt and socks, the more likely you are to slide back into bed!). Or make a date with a friend — knowing a friend is waiting on the corner is sure to help you get going.
