Light’s Influence On Body Weight

Light’s Influence On Body Weight According to research from Northwestern University, habitual early morning exposure to light is associated with a slimmer waistline. The study, published in the journal PLoS One, tracked the light exposure and caloric intake of 54 Chicago-area adults for one week and found that the earlier someone was exposed to light, the lower their body mass index (BMI) tended to be.

True Strength Moment: There are exceptions to the rule, of course. But if you want to put this science to the test on your body weight goals, researchers recommend shooting for 20 to 30 minutes of exposure to sunlight or bright interior lighting between 8 AM and Noon. That could mean early morning cardio on a cloudless day.
