Key Moments
Best lab results in a decade on keto: but fasting glucose alone can give false good news
Ferriss got his best lab results in a decade using a simple keto approach -- big salads with ribeye and cheese. But he warns that fasting glucose alone can mask insulin insensitivity. He's genetically predisposed to poor glucose disposal, a major driver of neurodegenerative disease.
"So I'll give you the punchline and then I'll back up. So, did Getting fast in glucose isn't enough. You can get false good news if that's timed luckily or well."
16:8 fasting may maintain metabolic machinery long-term: do 4 weeks keto then shift to IF
Ferriss did 4 weeks of keto to initiate metabolic adaptations, then transitioned to 16:8 intermittent fasting with two meals a day. He speculates doing strict keto once every 6-12 months could keep the metabolic machinery calibrated. He now does IF indefinitely with resistance training to preserve muscle.
"And then, maybe, if you do that, at least, and this is speculation, but once every six months, once every year, that you can keep the metabolic machinery where you want it. And so I did four weeks and I was like, enough, but I started leaning into intermittent fasting towards the end of that and experimenting with 16.8."
Exogenous ketones + IF for Alzheimer's: Rhonda Patrick's case study showed huge regain in function
Ferriss added exogenous ketones to his IF routine after Rhonda Patrick shared a case study of a progressed Alzheimer's patient who regained significant cognitive function using supplemental ketones. He also notes keto's anti-inflammatory effects were more noticeable than IF alone.
"And if you're in ketosis, what about intermittent fasting? If you have a tablespoon of heavy cream in your coffee in the beginning, are you sacrificing autophagy, you know, this kind of cellular self-eating slash cleanup? And she sent me a case study of an Alzheimer's patient, pretty progressed Alzheimer's, like very impaired function, who was given a ketone."
No biological free lunch: keto spiked Ferriss's lipids as a cholesterol hyperabsorber
Ferriss warns keto isn't free -- as a cholesterol hyperabsorber, he has to be careful with saturated fat and MCT oil. He's already on medication that helped him tolerate the diet, but emphasizes everyone needs professional monitoring of their lipid profile on keto.
"I'm a cholesterol hyperabsorber. So I also have to be very careful with saturated fat. It's not a free lunch for everyone."
