Do Intermittent Fasting Benefits Include Living Longer?

“We’ve known for a long time that if you reduce the calorie intake of rats or mice, they live much longer,” says Mark Mattson, chief of the laboratory of neurosciences at the National Institute on Aging (NIA) in Baltimore. Do these intermittent fasting benefits carry over to humans?

What happens in species closer to humans is more complicated. Rhesus monkeys fed 30 percent fewer calories lived longer in a study at the University of Wisconsin, but not in a study at the NIA.

How to Lose Belly Fat

Researchers assigned roughly 150 overweight, sedentary, middle-aged men and women with high LDL (“bad”) or low HDL (“good”) cholesterol to aerobic training, strength training, or both.

The aerobic training meant doing the equivalent of 19 kilometres a week at a vigorous pace on treadmills, elliptical trainers, or stationary bicycles. For strength training, participants did three sets of each of eight exercises, with eight to 12 repetitions per set, three days a week.

After eight months, those who did just strength training lost only subcutaneous (below-the-skin) abdominal fat.
