Hi welcome! Genetics is a humbling *****
I wanted start by saying IMHO Intelligence level and metabolic (or any favorable) genetics are not necessarily correlated. E.G. Stephen Hawkings.
(Also IMHO more likely in our current societal structure intelligence and environmental factors have a stronger correlation -such as food scarcity/deserts and access to nutrition education- but the jury is still out...)
I, likewise, hold a Master's but will put it in a folder to collect dust when it comes time to talk about my health. Family history, lifestyle, exercise, etc. those things mean more to the physcians.
Unfortunately those people never truly understand so you will likely be wasting your breath. Unless these people are the gatekeepers in your process or highly HIGHLY important in your life, do you really owe them a presentation?
A lot of Doctors call this a set point, YouTube bariatric surgeon Dr. Weiner. He talks about this often
This surgery does not ONLY alter the physical digestive pathways but also metabolic changes occur. Best to attend a few seminars, talk it through with a Surgeon you trust and research on your own while you decide.
There is A LOT of research out there, mostly medical journals easily found on Google Scholar or through other portals using your Uni's Alumni House access codes 😉
Good Luck 💙
