aside from a small improvement in the body’s processing of glucose, the fasters didn’t show benefits in health and longevity markers, such as inflammation levels.
Time-restricted eaters lost roughly twice as much lean mass—the body’s nonfat weight—as fat mass compared with a control group, according to ancillary findings in a study a few years ago.

And it only works for weight loss because you eat less food. If you cram the same amount of calories into fewer hours there is absolutely zero benefit.

Below is the actual study.
In the second six months of the study, all participants underwent IF. The IF regiment allowed only non-starchy raw and/or cooked vegetable salads for lunch and dinner during the fasting days, dressed with two tablespoons of olive oil, lemon juice, or vinegar. This novel “vegetable fasting-mimicking” approach helped to markedly improve compliance while avoiding calorie counting and minimizing activation of the insulin/IGF/mTOR pathway because of the very low calorie, protein, and carbohydrate content of non-starchy vegetables.
Feeding was not time restricted, as is the practice of most “intermittent” fasters. This is more a diet (non-starchy vegetables only on select days) rather than time restricted feeding.
Correction. The control groups skipped breakfast on the fast days. So there was time restriction on two or three days of the week.
All IF participants were asked to skip breakfast, lunch, dinner, snacks, and calorie-containing beverages on the fast days, but they were allowed to consume at lunch and dinner non-starchy raw and/or cooked vegetables “ad libitum,” dressed with a maximum of two tablespoons of olive oil
(~240 kcal) plus vinegar or lemon juice. Noncaloric drinks, such as black coffee, unsweetened tea, or zero-calorie soda, were allowed. Because non-starchy vegetables contain very small quantities of bioavailable calories, proteins, fats, and carbohydrates, this “vegetable fasting-mimicking” protocol (that does not require counting calories) was selected to mimic water-only fasting while minimizing participants’ social life disruption.
How late dinner was, nobody knows. There, presumably was at least twelve hours without feeding on the “fasting days.”
