Yearlong study: Time-restricted diets don’t work any better than cutting calories

Scientists say reducing caloric intake works just as well without restricting when you eat

Time-restricted eating is not more beneficial , than counting calories, study finds.Researchers at Southern Medical University in Guangzhou, China, .have determined that the form of intermittent fasting does not provide more benefits than calorie restriction when it comes to weight loss.The study was published in the New England Journal of Medicine.Our data suggest that caloric intake restriction explained most of the beneficial effects of a time-restricted eating regimen, Study researchers, via CNN.Bottom line, the determinant of weight loss, as well as reductions in body fat, visceral fat, blood pressure, and glucose and lipid levels, is dependent on reducing calorie intake, regardless of the distribution of food and beverages consumed throughout the day, Alice Lichtenstein, director and senior scientist at Tufts University's Cardiovascular Nutrition Laboratory, via CNN.The study observed 139 overweight to very obese adults over the course of a year.One group was instructed to reduce their caloric intake.Another group was told to eat the same amount of calories as the first group but between certain hours of the day.Food diaries and photographs were used to track compliance with the study. .By the year's end, participants in both groups lost up to 18 pounds, but those on a time-restricted schedule didn't lose any more weight than the other group.Decisions on the approach used to restrict calorie intake should be determined by what works best for an individual within the context of their lifestyle. The most important factor is identifying an approach that is sustainable in the long term, Alice Lichtenstein, director and senior scientist at Tufts University's Cardiovascular Nutrition Laboratory, via CNN

Many of us have put on an extra pound or two the past couple of years and are looking for ways to get back to our 2019 fighting weight.

You can try one of U.S. News & World Report’s best diets of 2022, which were selected by a panel of diet, nutrition and health experts. But there’s one diet you might not want to waste your time on, according to a new study.

In a paper published last week, researchers from Nanfang Hospital, Southern Medical University, in China, and the Tulane University School of Public Health and Tropical Medicine in the United States found that time restricted diets offer no benefits toward weight loss.

For their study, the scientists recruited 139 obese volunteers who agreed to reduce their caloric intake for a year. Participants were then randomly chosen to restrict their eating to 8 a.m. to 4 p.m.

“The idea was that eating only during such periods would coincide with important parts of the circadian rhythm resulting in higher metabolic activity burning more calories,” Bob Yirka wrote for Medical Xpress.

The participants were monitored throughout the year for not only weight loss, but also smaller waistlines.

At the end of the year, the researchers concluded that although the participants who restricted their meals to a timeframe lost more weight, it wasn’t enough to make a statistical difference. They also determined time-restricted dieting had no effect on the size of the volunteers’ waistlines.

According to the scientists, the participants would have lost the same amount of weight simply by cutting calories. The study was published last week in the New England Journal of Medicine.
