What will seem like an inevitable outcome in 20 years time because of GLP-1s

I'm kind of obsessed with the wide range of impacts GLP-1s is having on peoples day to day life and the wider impacts on the food system/social behaviours/family dynamics ect. A few examples: 1. My friend has completely stopped drinking (even post coming off) and primarily socialises now through sauna/runs/hiking ect 2. Another friend is very tired so has massively reduced their socialising and also their consumption of literally everything. She says she does a lot more chill hobbies at home on her own. 3. The often quoted stat that it is going to save airlines $580mil a year on fuel. If we assume there will be mass uptake of GLP-1s: what do you think the inevitable societal impacts of this are? What impacts that are non obvious now do you think it will have? One of my short term thoughts is an increase in nutritional deficiencies that require treating, and therefore increased pressure on the food system to overhaul (here's hoping).
