Microbes help orchestrate how the gut uses its genes ... read more
May 13, 2022
The microbes that help break down food actually tell the gut how to do its job better, according to a new study in mice. The researchers said it appears that the microbes are able to influence which of the gut's genes are being called into action, and in turn, that interaction might lead to a remodeling of the epithelial cells lining the gut so that they match the diet.

A single hormone directs body's responses to low-protein diet ... read more
May 13, 2022
A single hormone appears to coordinate the lifespan extension produced by a low-protein diet. Low-protein diets produce beneficial metabolic effects in aged mice, improving metabolic health, reducing frailty, and extending lifespan. These beneficial effects were also apparent when protein intake was reduced in middle-aged mice, even protecting against the detriments of obesity. Importantly, these beneficial effects were lost in mice that lacked FGF21, suggesting that its action in the brain is critical for the increase in health and lifespan.

Intense exercise while dieting may reduce cravings for fatty food ... read more
April 21, 2022
In a study that offers hope for human dieters, rats on a 30-day diet who exercised intensely resisted cues for favored, high-fat food pellets. The experiment was designed to test resistance to the phenomenon known as 'incubation of craving,' meaning the longer a desired substance is denied, the harder it is to ignore signals for it. The findings suggest that exercise modulated how hard the rats were willing to work for cues associated with the pellets, reflecting how much they craved them.
