Let's avoid conflating the stances in column one as contradictions to those in column two. Previous pinned tweet:
I get many requests for help. I have nutrition expertise, but I don't do consultations. If your questions require knowledge about your history to answer, you need more time and clinical experience than I have. I recommend @GeorgiaEdeMD. Previous pin:
Womp womp. Why do people gain weight? "Because they ate more than they burned!" Is that supposed to be a Dad joke? That's the physical description of gaining weight—a tautology. I'm asking why. Why did they eat more than they burned. I know what gaining weight means.
Interesting! DXA misclassification of IMF was not on my radar. Seems like it might be a legitimate concern in the relevant population (going from obese to not). medrxiv.org/content/10.110…
On a similar note, I wonder if retatrutide is perhaps better at reducing intramuscular fat than other GLP-1s, and if that contributes to those high “lean mass” loss numbers, since that seems to be how intramuscular fat is categorized on DEXA scans. (Could be mistaken, though!)
I particularly like the section of this post pointing out that with only a few technical-field exceptions, most papers are in fact easy to read to verify claims, and that the idea that only highly trained experts can do this serves only those with a deceptive agenda.
Popsci claims are the worst in not matching up with paper citations. Was arguing about this recently with fMRI studies and brain maturity claims, and dunbar's number. danluu.com/dunning-kruger/ has a nice small collection and includes a CS example too.
Not only "absurd, stupid, and insulting"; it incentivises false citations. If it were the author's responsibility to explain the support, many articles would never have reached publication, as the author would've been forced to eliminate or soften claims crucial to the argument.
After reading all those academic papers, I find the prevailing practice absurd, stupid and insulting, that bibliographical entries come without a summary and commentary of what is relevant about the book or paper being cited.
Another attempt to explain the problem with confusing caloric restriction with caloric deficit.
What sounds to me like a potentially major problem affecting you is the disconnect between caloric restriction and fuel partitioning. Obviously, a caloric deficit always corresponds to weight loss (independent of proportion of lean to fat mass lost), but the problem with CICO…
For the record, I don't think Vegans are in general dumber than Carnivores. I have heard as much or more ridiculous illogic from carnivore diet promoters as I have from vegans, and I've also had some great, honest and high level conversations with vegans. It's just that the…

Lol if my vet was telling me what my dog should eat BASED ON CANINES I would switch vets. All mammals have canines, herbivores and carnivores alike. Should a horse eat meat cos he has canines? Damn. This is basic knowledge.
Here is a quick response to Alex Leaf's brief analysis of the chapter in my unfinished book, Facultative Carnivore, describing the difference between omnivore and facultative carnivore, among other -vore classifications. The book was originally intended to comprise a more…
I was the person who fleshed out the original argument calling humans specifically "facultative carnivores", and even started a book by that name. The chapter on omnivores is what needs to be taken into account for any counterargument. facultativecarnivore.com/facultative-ca…
"[T]he (inappropriate) fatty acid supply to insulin sensitive cells in obesity *requires* insulin resistance."

“The hypothesis that linoleic acid generates insulin resistance promptly, as a direct effect of the generation of reactive aldehydes formed from linoleic acid in the bloodstream, is not supported by either of the Carpentier papers discussed here. “Far more plausible is the…

Somewhat surprising to me, because one theory for Neanderthal extinction was inability to harvest enough fat to cope with mega-fauna extinction (@bendormiki), but perhaps this hadn’t happened yet, or there was too much competition. Link to paper in press release.
