Diese beliebte Diät hilft Ihnen nicht, Gewicht zu verlieren, neue Studien finden

Die Forscher verglichen diesen Gewichtsverlustansatz mit Standardkalorienzählungen.


Most of us are familiar with trying to abnehmen: There are countless different approaches touted as the most effective method, and several branded diets that claim to offer the quickest or most sustainable option. These are often called "fad diets," as they tend to come in and out of fashion. Solutions such as the ketogenic (keto) diet, which focuses on high-fat intake, and the Atkins diet, famed for its low-carb approach, are two of those weight-loss trends—but the effectiveness of these diets is often debated by dietitians and medical professionals alike. In fact, a recent study evaluated another popular diet and found that it actually doesn't have additional weight-loss benefits. Read on to find out which approach experts say won't help you shed some pounds.

What we eat not only affects our weight, but also our risk for certain health conditions.

Food affects our bodies in more ways than just the number you see when you step on the scale. Research has shown that different food and beverages can both help and harm your health, with a recent study suggesting that Tee trinken could reduce your risk of developing dementia. Conversely, eatinghighly processed food was found to impact memory and could put you more at risk for the disease. Maintaining a healthy diet and ensuring we fuel our bodies properly can be challenging, which is why so many of us turn to diets that provide a specific plan or list of restrictions. But you may want to skip one popular approach, because it doesn't seem to do much.

Restricting your eating to specific times of day was not found to be effective.

You've probably heard the term "intermittent fasting," which includes a dietary approach called time-restricted eating. When following this diet, eating is limited to a period of six to eight hours a day. Researchers have hypothesized that eating during a certain window aligns with our inner circadian clock, which helps the body perform different essential functions throughout the day. Dasapproach has shown success in small study subsets, including rats and a small group of people with obesity, according to Die New York Times, but a new study found that time-restricted eating might not have any real effect.

Findings from the study were published in The New England Journal of Medicineon April 21, with researchers concluding that, in participants with obesity, time-restricted eating "was not more beneficial with regard to reduction in body weight, body fat, or metabolic risk factors than daily calorie restriction."

Researchers studied patients for an entire year.

Researchers at Southern Medical University in Guangzhou, China included a total of 139 patients in the study, 118 of whom had a follow-up visit at 12 months. All participants followed a calorie-restricted diet—consisting of 1,500 to 1,800 calories a day for men and 1,200 to 1,500 calories for women—with one group also following a time-restricted diet, eating only between 8 a.m. and 4 p.m.

Participants in both groups lost weight, averaging between 14 and 18 pounds, but there was no significant difference between the two groups at the 12-month mark. There was also no difference when analyzing waistlines, body mass index (BMI), body lean mass, blood pressure, and metabolic risk factors. When looking at the number of adverse events (an unexpected medical problem that occurred during the study) in each group, there were no substantial differences there either.

Experts say you don't necessarily need to avoid time-restricted eating.

While study results suggest that restricting the time window for eating is not effective, this is not to say it won't work for you, health experts said.ae0fcc31ae342fd3a1346ebb1f342fcb

"Almost every type of diet out there works for some people," Christopher Gardner, PhD, director of nutrition studies at the Stanford Prevention Research Center, told Die New York Times. "But the take-home supported by this new research is that when subjected to a properly designed and conducted study—scientific investigation—it is not any more helpful than simply reducing daily calorie intake for weight loss and health factors."

More research is needed to better understand time-restricted eating and why it may help some people and not others. For those who have difficulty counting calories every day, in particular, this form of intermittent fasting is a viable alternative.

"Obwohl dieser Ansatz nicht besser ist, scheint er nicht schlechter zu sein", als nur die Kalorienzählung, Louis J. Arnone , MD, Direktor des umfassenden Gewichtskontrollzentrums von Weill Cornell Medicine in New York, erzählte Die Zeiten . "Es gibt Patienten mehr Erfolgsmöglichkeiten."
