Early food a day seems to decrease appetite and could therefore help with weight loss, according to the authors of a small study.
Previous studies indicated that our circadian system or our body clock plays a role in weight loss as we burn energy and our appetite. And now it seems that eating earlier in the day matches these processes and can help you lose weight. The authors of the new publication published in the journal Obesity wanted to understand whether people lose weight because they consume more energy, eat less, or if something else is at stake.
The study comes as fasting diets like 5: 2 and 16: 8 have gained popularity, though the evidence that they are useful is relatively thin.
The researchers recruited 1
The first diet was a form of intermittent fasting called  eTerf [19459007)] where the participants ate three meals between 8 and 2 pm Breakfast was at 8 o'clock and dinner at 14 o'clock. The team felt that a 6-hour meal period is out of control and long-term sustainable.
The other diet served as a control in which participants took the three consumed meals between 8:00 and 8:00 pm or typical American meals.
On day four of each regime, researchers invited participants to spend 24 hours in a respiratory chamber to measure how much energy they burned. They also collected blood and urine specimens to measure hormone levels, and periodically asked participants to rate factors such as hunger, eating desire and ability, and fullness.
ETerf appeared to lower the level of ghrelin a hormone related to hunger, and appeared to aid in burning fat. It also seemed to reduce their desire to feel fuller on average.
Co-Author Eric Ravussin Deputy Managing Director of Clinical Science at Louisiana State University at Pennington Biomedical Research Center at Baton Rouge commented in a statement: " Coordinating meals with circadian rhythms or the internal clock of your body can be an effective strategy for reducing appetite and improving metabolic health. "
Courtney M Peterson, lead author of the study and assistant professor at the Department of Nutrition Sciences, University of Alabama, Birmingham, commented, "We suspect that the majority of people consider eating time strategies to be helpful in losing weight or weight Of course, to maintain weight, as these strategies seem to curb the appetite, which may help people to eat less. "
The authors admitted that their study was in some ways restricted, including the possibility of blood take two times, which means that it was more difficult to study metabolic hormones; The diets were only followed for four days, which may not be long enough to adjust the metabolism or daily rhythm. and the sample was relatively small and focused on men.
Hollie Raynor Professor and interdisciplinary researcher in the Department of Nutrition, College of Education, Health and Human Sciences at the University of Tennessee, Knoxville, who did not work on the paper have commented in a statement, "This study provides more information on how eating habits, and not just what you eat, can be important for achieving a healthy weight."
