Would be curious about the evidence you have that dietary fat is stored as (noticeable) body fat? 70% of the body is fat. Specifically, what evidence is there that dietary fat stored in a way that makes it so that it appears as noticeable body fat and causes meaningful weight gain?
Lyle's (science) problem is that he runs with every new paper, ignoring the fact that it directly contradicts the paper he touted last year.
21 years ago (I mean this literally, I read him then) he was touting on MFW how the discovery of leptin was going to render dieting obsolete in less than a decade.
He has a lot of good content, but it's always decisive, even when some is rong.
Fair enough, I think nutritional science is in its nascent stages, so the whole thing is pretty vague and on shaky ground. However, some cursory empirical evidence does back most of his claims around fat gain. At least to my armchair-nutritionist satisfaction.
Anecdata, everyone's favorite - I've seen someone gain no weight eating near 100% protein, while way over their TDEE. Kid you not, 4000 kcal of lean protein and mustard.
Also morbidly, you've got alcoholics (spirits), also traditionally under weight while consuming far in excess of their TDEE in ethanol (7 kcal per gram).
He was always big on pure caloric arithmetic, insisting that microbiome, macronutrient ratios, feeding/fasting timing, etc. couldn't possibly matter because no papers he liked said so.
