What can we do to boost the longevity hormone FGF21?
In the year 2000, a new human hormone was discovered. It was the 21st documented fibroblast growth factor, so they called it FGF21. Since its discovery, FGF21 has become recognized as a key agent for the promotion of metabolic and arterial health, leanness, and longevity. Inject it into fat monkeys, and they lose body weight without reducing their food intake. And they don’t just lose a little weight—they have a 27% drop in body fat while eating the same amount.
