if a person came to me and said look I weigh 260 lbs I probably should weigh 200b I would tell them you know if I agreed with that assessment I'd say being closer to the 200 is probably fine you don't need to be at the 260

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
His target body weight.
Um, and this just reminded me of something that we should have pointed out like talking about the protein requirements, grams per kilogram body weight. I do think it's important like cuz we're talking about we were just talking about obese people.
for someone with overweight or obesity, calculating protein needs on estimated lean body mass or ideal body weight is preferred.
tailoring protein needs for individuals who are overweight, emphasizing adjustments based on lean mass rather than total body weight to aid in effective fat loss while maintaining muscle mass.
So, if you are 300 pounds and you should be 200 pounds, let's say, you would calculate it at the weight that you would be where you would be at your lean weight, you know, for a guy, 12% to 15% body fat.
if you would actually uh modulate your protein requirements towards the tissues that require the protein then it would be better to basically base it on fat-free Mass
people most people aren't going and measuring their fat-free Mass but that is something that can be done people can go get would you say doing a dexa scan would be um something that would be more I mean there there's so many options I mean you can make a body volume scan you can there's nice apps nowadays we heard it yesterday in the conference also uh but you can also do a dexa scan or body circumference measurements or but most people know how much overweight they are
So if you have the fat free Mass all the organ mass and the muscle and actually say like hey 08 for an 80 year old uh or 880 kilogram weighing man then also related to the 08 based on those 80 kogs and not on the 20 or 40 excess fat depos that you have on you
it's generally agreed upon that protein needs should be calculated based on a lean body mass or an adjusted body weight reflecting a healthy body fat percentage so for example 12 to 15% for men and around 20% for women this prevents unrealistic targets especially for those who are overweight or obese
