Fasting can boost health in people, as trends like intermittent fasting continue to hold sway.
Researchers found that combined with eating less, fasting reduces frailty in old age.
Fasting alone can improve blood sugar and liver metabolism.
Mice that ate fewer calories but never fasted died younger than fasted mice.
Dudley Lamming, Associate professor at UW–Madison says "... was something that everybody saw, but it wasn’t always obvious that it had biological significance"
Researchers designed four different diets for mice to follow.
One group ate as much as they wanted whenever they wanted.
Another group ate a full amount, but in a short period of time.
The other two groups were given about 30% fewer calories either once a day or dispersed.
Some mice had a long daily fast while others ate the same reduced-calorie diet but never fasted.
Fasting alone was enough to improve insulin sensitivity and to reprogram metabolism.
