Frame size and BMI

[switchname]

I love hearing about the positive stories on this board, and hopefully I can have one to add.

I’ve been on wegovy for eight months now and have lost over 20% of my body weight and my current BMI is 21.6. I’m post menopausal and still have flabby bits left on my stomach, thighs, arms, etc. I’ve been working out daily and have increased my skeletal muscle so my body composition has also improved.

I am quite small boned, so I’m keen to hear what other small framed people advise for BMI. I’m thinking that a BMI of 21 would be acceptable. I have a health condition which means excess fat is not recommended.

With thanks 😊

Sure but the absolute weight difference is minimal. The range for dry weight bones for a woman will be 2-3kg. So won’t matter for BMI.

BMI absolutely does take different builds into account, that's why there's such a large range of healthy weight for any given height. There'll always be extremes at either end of course, but it's designed to cater to most body types including muscular. Maybe not rugby forward/heavyweight boxer/Olympic lifter muscular, but the vast majority of top level athletes and sportspeople are a low to healthy BMI.

we may be talking about 2 different aspects here. I don't mean that BMI doesn't matter because someone has 'heavy bones' or anything like that. Just that a person with slender bones will look different at the same BMI than a person with robust bones, because the latter has a bigger frame.
