A research carried out in mice discovered that intermittent fasting introduced advantages past weight reduction, suggesting the apply might assist the physique higher course of glucose and scale back age-related declines in intestinal operate. Researchers will current their work this week on the American Physiology Summit, the flagship annual assembly of the American Physiological Society (APS), in Lengthy Seaside, California.
Our research means that intermittent fasting is a useful dietary apply to manage weight achieve, enhance blood glucose ranges and promote optimistic intestinal results by decreasing irritation and oxidative stress whereas altering intestinal construction.”

Intermittent fasting-;through which an individual eats after which refrains from consuming on a set schedule-;has gained consideration in recent times as a method for weight administration. The researchers sought to learn how it’d have an effect on well being in older adults.
To do that, they used mice that have been genetically altered to speed up ageing. A number of the mice had meals out there on a regular basis whereas others had entry to meals solely throughout alternating 24-hour cycles. After eight months, the mice that have been fed each different day had gained much less weight and in addition had structural modifications within the small gut related to improved glucose management and lowered irritation.
“Our information counsel that the burden loss induced by intermittent fasting will not be seemingly solely as a result of calorie restriction but in addition not less than partially facilitated by a change in glucose metabolism,” Vroegop mentioned. “This might indicate that the burden loss induced by way of intermittent fasting is extra more likely to have longer results than easy calorie restriction.”
The research targeted particularly on the jejunum, a portion of the small gut the place most nutrient absorption happens. “As mammals age, there are inherent damaging modifications to the morphology of the small gut that impression the power to soak up vitamins and keep its construction,” Vroegop mentioned. “Our research means that an intermittent fasting weight loss plan might assist stop these age-related modifications by returning the jejunum to a ‘youthful’ model of itself.”
Whereas the pattern dimension was comparatively small (32 mice in whole), the researchers famous that the consequences appeared extra pronounced in feminine mice than in males, with females displaying better variations within the well being and look of the small gut and in the best way sugars are transported. Nevertheless, the impact on blood sugar ranges was stronger in males than females. The workforce is engaged on follow-up research to higher perceive the drivers behind these sex-specific variations.
Vroegop cautioned that it’s tough to extrapolate from mice to people and the research shouldn’t be construed as offering medical recommendation. As a result of intermittent fasting is a comparatively new space of research and there’s extensive variation within the fasting regimens utilized in totally different research, there’s not but a scientific consensus on the dangers and advantages or the optimum fasting technique.
