I have PCOS as well. Before last year I did calorie counting and lost very close to 25lbs with usually between .5-3lbs a week.
I had to watch my carbs as well though. I am diabetic but carb watching is also good for PCOS. I think that is the key paying attention to not just calories but carbs too. Not that you have to go all no carb or super low carb but lower then average I think is good. Like my doctor told me to not go over 200 carbs because she knew I was a carb addict and it would be tough lol but I try to keep it a bit lower then that even.
I agree I don't like having any off limit foods. I think moderation is the best but at the same time moderation is easier said then done lol. So some things I just have to stay away from for now or I will binge. I have to be very careful with bread and pasta lol
So sometimes I buy premade pasta dinners like lean cuisine and stick with whole wheat and make sure I make only small bits of pasta at a time so I can't go back for seconds (and thirds, fourths lol)
But bleh I gained it all back because I just went off plan
but I am back again and doing calorie counting again and loving it. I like the freedom it does give.
Goodluck to you!
