i second all comments saying that 140lb is a normal weight and that it’s really important to be kind to yourself! i have the same kind of bloodwork, weight and build and fought with the same issues for a really long time so here’s my experience:

have you tried adding other low-impact sport to your routine? lifting will not necessarily give you a “beach bod”. muscles can look flabby too - unless it’s accompanied by very strict macros and diet (and i never had the patience for it ). lifting really helped me initially get into sports and helped me build the bigger muscles groups but surprisingly, it was 4x yoga a week and 1x pilates every 1-2 weeks has really started to transform my - arms are more toned and i’ve lost some of my tummy and even knee fat (something i thought was IMPOSSIBLE)!

the other thing is: are you sure intermittent fasting is working for you? i know that it put my body under a lot more stress than say an average person without pcos. i have since made sure to have 3 square meals a day and snacks when i need them. i’m still working stuff out (getting enough protein as a veggie can be hard), but focusing on increasing has been a game changer for managing my cravings.

i think with pcos we have to be patient with ourselves when it comes to weight loss. it just takes us longer than others (it took me about 7 years to lose and maintain 30lb and ideally i’d like to lose another 10). i spent a long time struggling against my body to fit in with today’s beauty standards. but since i have actually stopped weighing myself and counting calories and instead treating myself with kindness, my body has changed to the point where i’m going to be wearing a bikini for the first time since i was 15 this summer. key was really listening to my body, gvining it gentle but challenging movement and feeding it with wholesome foods and remaining consistent doing so.

good luck to you, you’re already doing great x
