Mindsip insights from this episode:
Stimulate FGF21 with a 9% protein diet
A human study successfully stimulated FGF21 by having participants consume a diet where only 9% of total calories came from protein.
Reduce protein intake to boost FGF21 levels
Human studies show that you can naturally increase FGF21 levels simply by reducing your protein intake.
Reduce harmful ceramide levels with FGF21 hormone
The hormone FGF21 dramatically reduces the production of ceramides, harmful molecules linked to inflammation, cell death, and insulin resistance.
Utilize FGF21 to protect organs from harmful fat spillover
FGF21 improves the ability of fat cells to store fat, preventing harmful fat spillover into organs like the liver, a condition known as ectopic fat.
Boost FGF21 levels to enhance metabolism and maintain leanness
Mice with higher FGF21 were leaner and more muscular, and had a higher metabolism that allowed them to eat more food while maintaining a lower body weight.
Increase FGF21 levels to extend lifespan
In mice, increasing the hormone FGF21 led to a substantial 26% increase in lifespan.
Consider protein needs before reducing intake for FGF21 boost
Reducing protein to boost FGF21 may not be suitable for those who exercise intensely or for adults in their 60s and beyond, as their protein requirements are higher.
