Once or twice per week you can have a treat. Remember you will have 600-1000 calories to work with in the main meal. This should make it pretty easy to enjoy some of your favorite foods or go out to a restaurant with friends/family. Just make sure to not go over the calorie budget for the day. If you do end up going over the calorie budget for the day then you can compensate by slightly reducing calories the following days.

Let me start by saying I don’t work for Greg or Kinobody. Despite his douche bag filled videos and ridiculous demeanor, Greg’s Greek God Kinobody program has worked for me. Once you pay, you get the online program (which is pretty simple), access to the forum (can see tons of inspiring, crazy transformations and get quality advice from the other 10,000 plus users on the forum) and of course, loads of advertisements on his other products. I’d give it 4.5 starts if I could-it’s a little unorganized and the constant barrage of advertising is annoying but the results are hard to argue with. In the end, any program comes down to what you put into it. Nice thing about his stuff is the time commitment isn’t as intense as insanity, p90x, etc. and you get to eat what you want, just in moderation and at certain times of the day.
I have PCOS as well. Research a PCOS-specific diet. It often overlaps with Keto or Paleo recipes. But you have to also avoid holstein cow produced dairy products, red meat, pork, soy products (which are in almost every processed food) in addition to carbs and sugar. And absolutely avoid anything you can’t be sure doesn’t have extra hormones injected into it (like many mass-farmed meats). Vigorous exercise is also necessary to lose weight when you have PCOS (It’s much, much more difficult for us to lose weight than people with normal hormonal balances).
