A examine in mice discovered that intermittent fasting had advantages past weight reduction, suggesting the follow may assist the physique higher course of glucose and cut back age-related declines in intestinal operate. The 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 examine means that intermittent fasting is a useful dietary follow for controlling weight acquire, enhancing blood glucose ranges, and selling constructive intestine results by lowering irritation and oxidative stress whereas altering intestine construction.”

Intermittent fasting – wherein an individual eats after which abstains from consuming on a set schedule – has gained consideration in recent times as a weight administration technique. Researchers tried to determine the way it would possibly have an effect on the well being of older adults.
To do that, they used mice that had been genetically altered to speed up getting older. A few of the mice had meals out there on a regular basis, whereas others solely had entry to meals throughout alternating 24-hour cycles. After eight months, the mice that had been fed each different day had gained much less weight and likewise had structural modifications within the small gut related to higher glucose management and decreased irritation.
“Our knowledge counsel that intermittent fasting-induced weight reduction is probably going not solely as a result of caloric restriction but additionally, at the very least partially, facilitated by a change in glucose metabolism,” Vroegop mentioned. “This might suggest that weight reduction induced by intermittent fasting is extra more likely to have longer-lasting results than easy calorie restriction.”
The examine targeted particularly on the jejunum, a portion of the small gut the place most nutrient absorption happens. “As mammals age, inherent dangerous modifications happen within the morphology of the small gut that have an effect on the flexibility to soak up vitamins and keep its construction,” Vroegop mentioned. “Our examine means that an intermittent fasting food plan could assist forestall these age-related modifications by returning the jejunum to a 'youthful' model of itself.”
Whereas the pattern measurement was comparatively small (32 mice whole), the researchers famous that the results appeared extra pronounced in females than in males, with females exhibiting higher variations within the well being and look of the small gut and in the way in which sugars are processed. transported. Nonetheless, the impact on blood sugar ranges was stronger in males than in ladies. The staff is engaged on follow-up research to raised perceive the elements behind these sex-specific variations.
Vroegop cautioned that it’s tough to extrapolate from mice to people and that the examine shouldn’t be interpreted as medical recommendation. As a result of intermittent fasting is a comparatively new space of examine and there may be broad variation within the fasting regimens utilized in completely different research, there may be nonetheless no scientific consensus on the dangers and advantages or the optimum fasting technique.
