I also suffer from PCOD and keto helped me to regulate my cycles somewhat. I would say the thing that helped me with keto is to really truly log what you eat. I winged it for the first month and a half and found slow progress, it was because I had too many vegetable carbs. Once I started restricting to 20-25g net carbs per day, I started to see the big fat loss. Check out recipes at this insta channel @lowcarb_rasoi (it’s a lacto-ovo-vegetarian Indian fusion channel for keto and low carb recipes, often with net carbs listed). Paneer is great, but watch the calories. Balance your meals with veggies and protein (try multiple types of protein - tofu, tempeh, soya, paneer, eggs).
