Asian Scientist Journal (Dec. 16, 2022) — Consuming a high-protein weight loss program might assist stop weight regain after weight-reduction plan, say researchers from China in a paper revealed in Nature Metabolism.
Weight-reduction plan, or extra particularly dietary restrictions, are a number of the commonest strategies of shedding weight and fats mass. Nevertheless, though short-term weight reduction may be achieved by merely consuming fewer fatty meals and monitoring caloric consumption, long-term weight upkeep is far more troublesome to achieve. In lots of circumstances of weight reduction as a consequence of restrictive meals consumption, individuals will discover a fast weight rebound after returning to their earlier dietary habits.
A crew of researchers led by Professor Zhai Qiwei from the Chinese language Academy of Sciences, China have found that a rise of a particular bacterial pressure enhances absorption of lipids within the intestine, resulting in fast accumulation of fats in mice.
As a part of the research, lab mice have been placed on a weight-reduction plan protocol that mimics restrictive caloric consumption or intermittent fasting for 3 to 6 days and weighed to file their preliminary mass. Researchers then used 10 weight-reduction plan protocols to research the consequences of post-diet “refeeding” on fats mass in mice. In each the restrictive weight loss program and the next refeed, the identical feed was used. The mice have been weighed as soon as once more and their fats mass accumulation was subsequently measured.
Information from this experiment confirmed that the mice have been fast to regain fats mass after post-diet refeeding. In actual fact, for mice who have been on a restrictive weight loss program for 3 days previous to the refeed, their fats mass accumulation was the quickest.
The researchers checked out whether or not the mice’s fats absorption within the intestine and subsequent fats metabolism have been affected throughout the restrictive weight loss program section. A fats absorption and lipid metabolism assay have been performed on mice on the restrictive weight loss program.
Outcomes from these assays confirmed there was a rise in fats absorption within the intestine from discovering excessive quantities of lipids in fecal matter. Additional evaluation revealed that there was a lower in whole lipid oxidation and a rise in white adipose storage. In brief, much less fats is being damaged down whereas extra fats is being saved within the physique, resulting in a rise in fats mass accumulation after restrictive weight-reduction plan.
To find out any potential dietary interventions that would assist scale back this enhance in fats absorption and storage, the researchers fed mice both a high-protein weight loss program, low-protein weight loss program or normal-protein weight loss program throughout the post-dieting section.
Outcomes confirmed that the high-protein weight loss program was capable of stop fast mass fats accumulation within the mice in comparison with the low-protein and normal-protein diets. The researchers took a deeper take a look at the mice’s intestine microbiome, to find out if there have been any adjustments within the intestine microbiome throughout each the restrictive weight loss program section and the high-protein refeeding section.
The researchers found {that a} pressure of micro organism known as Lactobacillus was extremely ample within the intestine of mice throughout a restrictive weight-reduction plan section and through refeeding with a normal-protein weight loss program. The abundance of Lactobacillus noticed a close to 50 % lower throughout a high-protein weight loss program refeed.
This confirmed that the presence of Lactobacillus within the intestine together with a high-protein weight loss program after a restrictive weight loss program can have an effect on fats mass accumulation and subsequent weight achieve. The researchers imagine that taking particular post-dieting feeding habits, comparable to consuming a high-protein weight loss program, is “probably an relevant technique that may alleviate the detrimental effecting of terminating weight-reduction plan.”
