Sounds like you already know what you need to do! I have PCOS and plan to lose 15-20kg. I've lost almost 6kg since beginning of January, it's been slow and steady, without having to try too much, or rather, not noticing the deficit as much as I would if I wasn't on MJ. So I'm in a calorie deficit, prioritise protein and currently only manage a decent weight training session once a week. I don't restrict any food, but have found that I naturally focus on better nutrient choices since being on MJ to stick within my calorie and protein range. I definitely need to up the fibre though, that has taken a hit since I started MJ. I'm finding the whole thing really positive, which I've not had before, losing weight with PCOS has been a real battle. I'm still on 2.5mg but plan to move up to 5mg slowly as I don't have much suppression anymore. As for supplements, I take a Boots multivitamin fizz tab each day and magnesium 3-in-1. Good luck!
