Advice please!

So I’m a 22F who has PCOS and I’m currently embarking on my weight loss journey. In the past, I manage to go down 5 kg from 65kg but have recently gained it again so I’m back on the 65kg.

I find it quite hard to pass the 60kg mark but I’m not sure why

Overall, I’m looking for a lean and slimmer body type. I’m trying to eat more protein and healthy fats.

These are the stats at the moment:

144 lbs Body water: 51.3% Body fat: 30.6% Muscle mass: 27% BMI: 25.6 Bone mass: 2.4kg BMR: 1551 kcal

I would like to be down 10kg but overall, I would just want to be lean and toned

Any advice would be appreciated :)
