A new study has found that intermittent fasting — a celebrity-favored diet in which eating is limited to about an 8-hour window during the day — does not help people lose weight, and may even result in a loss of muscle mass. The study by researchers from the University of California at San Francisco (UCSF) found that those who intermittently fasted for 12 weeks only lost a half-pound more than a group of people who ate normally. Previous studies of the diet promised a range of benefits, from weight loss to longevity; however, much of the research only studied mice. The new findings, published in JAMA Internal Medicine following a clinical trial, were shocking to the researchers — one of whom was even on the diet himself for seven years. “I went into this hoping to demonstrate that this thing I’ve been doing for years works,” lead author and UCSF cardiologist Dr. Ethan Weiss told CNBC.
