********CRITIQUES, RULES, AND NOTES********

Be aware of the following rules before posting comments:
- Please do not post summaries of the video in the comments - it damages retention on the video and YouTube is less likely to promote it (these videos cost me a lot of money to produce).

Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:

Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached.

RULES:
If your comment is rude, you will be banned.
If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.

If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).

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.
