anyone w/ pcos and have lost weight, do you have any tips?

basically: i'm 26 and want to kind of take charge of my life before i turn 30. i weigh 110 kilos and don't really want to look at numbers. i have always kind of weighed between 90-110 kilos since i reached my 20s.

i want to work out and eat better. currently i eat mostly 2 meals a day with snacks in between. don't drink alot of sugary or gassy drinks either, maybe like 1-2 a month (but i love coffee - usually get it without sugar but with milk). sometimes junk food like chips but it's pretty rare. maybe like 1-2 in 2 weeks only. chocolates rare too, like once every 1-2 weeks. i usually eat rice for lunch with protein and vege (i always try to eat more vege than rice & protein, following that general 1-2-3 rule where 1-carbs, 2-protein, 3-veges) and usually stay away from eating rice at night (sometimes i do tho. it's hard, i'm asian and i live either with parents or in college where i can't cook for myself.)

as for working out, i currently live in college and do a lot of walking, but there are some days that i'm kind of stagnant and don't do much. but i try my best to get some walking in. i do wish to go to the gym soon and will probably start going to the gym around mid-feb.

1 thing i'm scared of is saggy skin. i would say my arms are big and my tummy is big. i have bigger boobs too which i love and cherish lmao and wouldn't want to lose that. i don't want to lose a ton of weight, just tone down my tummy and arms and kind of gain muscle. there's no "inch" or set amount i want to set as a goal. just to feel good in my body and with how i look like.

if you've gone through a similar experience, would you mind sharing some tips or just what you've been doing so far? thank you :)
