The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
Actually, in mice, you can obtain exactly the same longevity extension that you would obtain, the 30% of caloric restriction by intermittent fasting. So, it's logistically much more simple to take out the food from the cage completely, and to put back the food on the next day. So it's one day without any food, and another day with normal nutrition.
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.

And at the end, so, you have an oscillation of the weight of the mice, 10% every day. These oscillations tend to become smaller because the mice somehow adapt to this sort of stress, but the final result is that the intermittently fasted mouse has the same weight as a normally fat mouse. A difference with the calorically restricted mouse, it weighs also 20% to 30% less. And in spite of this difference in the body weight, intermittent fasting allows for a lifetime expansion in the same way as does caloric restriction.
