Light may have something to do with weight gain

Something as simple as light may affect a person's weight, according to new research from Ohio State University.

A team found that over an eight-week period, mice that were exposed to dim light at night gained 50 percent more weight than those that were not exposed to light during the evening hours.

Study author Laura Fonken says the findings held true despite the fact that the mice who were exposed to light at night were not eating more or getting less exercise than the group of mice that were not exposed to light.

"Something about light at night was making the mice in our study want to eat at the wrong times to properly metabolize their food," says study co-author Randy Nelson.

Such research findings may help shed light into ways humans can regulate their own weight. Being overweight has been linked to a number of troublesome health conditions including Type 2 diabetes, heart disease, and some cancers. Furthermore, being obese and having such health conditions can also cause one to pay higher life insurance premiums.

While some may still question the benefits of the aforementioned study, most are in agreeance that eating a balanced diet and getting exercise on the regular basis are the foundation to a healthy life.
