The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
outside of that Spectrum Most people who just say hey like I want to feel great throughout the day to be able to do a bunch of different things how do you know a couple things there's a lot of biological markers you can take um there's also just some some practical takes
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
It's that I really I want that I want that real switch to be on and I want it to be on for a little bit of of time and then I want to turn it off by eating. You know, I'm not starving myself. And I think you can go too far with exercise and with fasting.
I'm also a believer that your metabolism is a moving target so somebody that was once 250 and overweight and had a you know really you know bad body fat composition now they're 200 and they're in good shape I believe that they may be able to tolerate some carbohydrates more
I think the idea of metabolic flexibility is super important the ability to have a dual fuel source
metabolic fle flexibility I mean there's definitely longevity benefits for that
I get it. If you pluck the average person off the street they're probably less likely to be good at burning fat than they are carbohydrate. So on aggregate, we probably need to get more people better at burning fat. I'm I'm with you on that one. But metabolic flexibility is not just maximize fat burning. Those are not the same thing. That and that's how people will often describe that. If you go too hard on one side of the other of the equation, you'll see a whole host of adaptations that compromise the ability to do the other things. That's not metabolic flexibility. It is still specialization.
So the term metabolic flexibility has been hijacked and the way that it is described now colloally is not what that phrase ever started to be and it's not what that is intended to be. It's so crazy because metabolic flexibility has got turned into maximizing fat burning. It's supposed to be metabolic flexibility which means you have the ability to run the whole gamut.
