Eating only during the day might help you live longer than eating at night, according to the findings of a new study published in the journal Science. Researchers from the University of Texas Southwestern Medical Center gave reduced calorie, low fat, low sugar diets to mice, which extended their lifespan 10 percent. But giving the same diets at night, when rodents are most active, increased the longevity of the mice 35 percent. The researchers believe that a similar plan for people would restrict eating to the daytime hours. If you want to try intermittent fasting or time-restricted eating, when you eat all your food for the day within a six- or eight-hour window, it might be advantageous to eat your food during breakfast and lunch instead of lunch and dinner, at least in terms of living longer.
