The problem for old people is that it's hard to get bone and muscle, as most of them simple will not exercise. Also stomach acid drops a lot in old people which makes protein digestion even harder. In the ideal world, assuming GLP1 is not toxic long-term and that they can keep the weight off, people would exercise to regain muscle. But if those people got obese in the 1st place, do you really think many of them will suddenly uptake exercise for more than a New Years resolution week or two?
