being overweight can cause medical issues
idk its called overweight and underweight for a reason, neither one is too terribly good for you, and the more under/overweight you are the worse it is for you, and bmi calculators dont take muscle vs. fat into account so you can be “overweight” and be perfectly fit.
dont take your health for granted or assume that someone saying there’s a risk factor for you due to your weight is because of “fatphobia” or whatever. your body is made to function in certain parameters and over or under those parameters can cause bone issues, blood pressure issues, organ issues, etc., and you don’t have to fit into an ideal body if you don’t want to, but controlling caloric intake and what your caloric intake consists of can help with a lot of medical issues like joint pain and reduce the risk of things like diabetes and heart disease because of how you’re treating your body
