Creator description · original language
In this thought-provoking conversation with Dr. Nic Verhoeven, PhD, creator of the Physionic channel, we delve into the controversial topic of the “sugar diet.”
Join us as we break down the science behind this unexpected diet trend, discuss the roles of the hormone FGF-21, and what new research published in top journals (Nature Metabolism and Cell Metabolism) has to teach us well beyond this diet fad. We tackle the physiology of the sugar diet, the mechanisms behind protein restriction, and share surprising findings that might challenge conventional wisdom.
