These biologists from the University of California-Riverside show, in mice, that exercise practiced at a young age brings its maximum positive earnings in adulthood. Which ones? Continued good habits of exercise and food, but also reduction of body mass and finally,
on a biological level, higher levels of the hormone leptin "satiety". The findings, reported in the journal Physiology & Behavior, also suggest that certain types of exercise, exercised over time and rather moderate, may not stimulate appetite and thus help maintain or even loss weight.
