Im not questioning the quoted studies in any way but its either my language barrier or BBC has built a clickbaity title based on just one quote “ It wouldn't surprise me that improving people's health this way actually slows down the ageing process”
Wonder what would they write had he said “it wouldn’t surprise me if people get blue skin and tiny horns…”
> The studies - part of the Select trial - tracked more than 17,600 people, aged 45 or older, as they were given either 2.4 mg of semaglutide or a placebo for more than three years. Participants were obese or overweight and had cardiovascular disease but not diabetes.
Exciting stuff. What does data look like in people that aren’t obese?
I thought calorie restriction was another order of magnitude, beyond "normal" weight. But I guess if obesity was causing accelerated ageing, you could say not being obese is delaying ageing.
I'll have to look into it more, but from what I've seen, it seemed that people had to restrict calories so much that their immune system was underactive (which may be a large part of why it works).
I don't think this should be downvoted. For overweight people, the benefits of these drugs exceed the risks of side effects, but for healthy people there may be no benefits.
*Another tip is to stay in the sun. The data on sun exposure has largely reversed over the last decade; sun exposure is positively correlated with improved health outcomes, but should be done in moderation as to prevent skin issues.
> In general, scientists think 5 to 15 minutes -- up to 30 if you’re dark-skinned -- is about right to get the most out of it without causing any health problems.
I don't disagree with your premise, but I also don't fully agree with it as a comprehensive explanation. Overeating seems to be a uniquely American problem, and independent of a nation's food security status. For example, the obesity rate in Japan is much lower than that of the US and I don't think that's due to them (a) not having enough food to over-indulge or (b) somehow having evolved a shutoff mechanism that Americans have yet to develop.
To me, it seems almost entirely explained by culture.
