There also wasn’t any significant difference in other health markers between groups, including blood pressure, triglyceride levels, total cholesterol levels, fasting glucose levels, or insulin levels. All participants received a scale to use at home and weighed themselves twice a day. The article was rated one of the most popular among readers after its release on September 28. Recent clinical evidence bears out the fact that repeated fasting does not cause muscle loss. Moskovitz adds that IF isn’t safe for everyone: People with certain serious medical conditions, those who are pregnant or breastfeeding, kids, teens, and people with a history of disordered eating patterns should avoid IF. The answer to that question is likely more individualized than studies might suggest, according to Jason Fung, M.D., author of "The Complete Guide to Fasting" and "The Obesity Code. food surveys are “notoriously inaccurate, decreased bone density, altered metabolism, and increased risk of falls and fractures.

Intermittent fasting (IF) is a popular method often used for the goal of weight loss and to improve certain markers of health. “Intermittent fasting needs to be thoroughly studied given the surprising loss in muscle in this particular study.”.

While it’s unclear if everyone will encounter muscle mass loss on a 16:8 diet, the study’s findings do throw some cold water on the hype surrounding IF. His resulting study, which was published this September in JAMA Internal Medicine, is a randomized controlled trial (RCT), making it one of the most rigorous studies on IF to date. Intermittent fasting is touted as a weight loss method, but a new study suggests the diet may cause substantial muscle loss. But considering that losing muscle mass is associated with decreased bone density, altered metabolism, and increased risk of falls and fractures (especially as you age), this is a concerning find. What’s more, most of the weight loss in the IF group was “lean mass” (muscle, not fat), which wasn’t the case for the regular diet group. Oh hi! Here’s the full 101 on the many forms of intermittent fasting, straight from a top RD: Dr. Weiss’s study randomly put a total of 116 overweight or obese adult participants into one of two groups. Fifty of the participants in the TRE group underwent in-person testing to measure fat and muscle mass, blood sugar levels and energy expenditure. Fasting diets, also known as time-restricted feeding diets, have proven effective in previous weight loss studies. 22 In addition, there was a highly significant between-group difference in ALM. All rights reserved. “The weight loss on average was very modest, about 2 pounds in 12 weeks for the TRE group compared to no statistically significant loss for the CMT group.”. “This form [of IF] as it is, without calorie restriction or a different diet, does not appear to work,” says Dr. Weiss. The study was published on September 28th in JAMA Internal Medicine and the main takeaway was ‘Time-restricted eating did not confer weight loss or cardiometabolic benefits in this study.’ The approach they took for the study was the common 16:8 Method where the period of the day in which someone eats is restricted to just 8 hours, often noon to 8pm or 1pm to 9pm. Intermittent fasting has been a form of eating that's grown in popularity over the last five years. About half were instructed to eat three meals per day, with snacks allowed, between 7 a.m. and 11 p.m. “We did not tell them how much to eat or what to eat, but it was pitched as a weight-loss study,” says Dr. Weiss. All other participants were scattered throughout the nation and only monitored weight change. That may be because IF participants ate less protein, says Moskovitz, or because they exercised less than the control group. People on the IF eating plan had minimal weight loss that wasn’t significantly different from the control group (1.17 percent versus 0.75 percent). Dr. Weiss says that his team intended to include food logs but ran into a technical issue. Time restricted eaters (TRE) were instructed to eat their meals during an 8-hour window between 12 p.m. and 8 p.m. and abstain from caloric intake from 8 p.m. to 12 p.m. the following day, giving them a 16-hour fast. Ethan J. Weiss, MD, a cardiologist and associate professor at the Cardiovascular Research Institute at the University of California, San Francisco, tried IF after reading a few studies on it.
