Sunlight and Weight

If you're looking for a new way to stay fit and lean, new research suggests simply starting your day with a bit of morning sun.

A small new study reveals that just 20 to 30 minutes of morning sunlight may help protect against excess poundage. 54 men and women enrolled in the 1-week experiment during which participants kept food
diaries and experts monitored sleep and light exposure habits.

The result? Those who got the most rays between 8 AM and 12 Noon had significantly lower body mass indexes compared with those who got the bulk of their exposure during afternoon or evening hours.

In fact, no matter when or how much they exercised, ate, or slept the amount of morning sunshine a participant got was determined to affect about 20% of his or her total body mass index variance.

The investigating team concluded that morning sunshine has a direct impact on our internal body clock, with sufficient exposure helping to maintain a healthy metabolism and a trim waistline.
