I guess the creative speculation about fatness being an evolutionary advantage over neanderthals is new to me. I do not find it at all compelling though and I'm as confused as you about why this is being upvoted

Yes, it is the exact same 'diet and exercise' advice that anybody serious understands is the closest to absolute truth that they'll ever see in nutrition.

I didn’t say it was untrue. I said it was ineffective as advice for the general public. We might blame the public for not being compliant or disciplined, but that’s pointless. This advice is suitable for a different reality than the one we live in, populated by imperfect people.
