I have always, ALWAYS believed that completely taking things out of your diet is setting yourself up for disaster. I am not insulin resistant so at times, I have let myself munch on sweets a little too much. I realize it and then work out a little longer that day and the next.

What I have found that works for me is that I found healthier alternatives to snacks that worked with my type of PCOS. I let myself have a SMALL sweet or junk food meal once or twice a week. One day a week I have a cheat meal. Keeping it in my diet in smaller portions has let me get those fixes when I want them and stay away from them the rest of the time.

I switched soda's to diet pepsi's new aspartame free blend and its my favorite naughty treat. I just discovered a water made by Ocean Spray called PACt. It has 1g of sugar for 16oz and its really not bad at all. It does have a tad bit too much sodium (75g) so I really limit those. Also, cranberries are a little expensive but I have found a company that makes them with less sugar. I can't think of the name right now but it makes a great sweet snack you can have a handful and not feel guilty.

Finding recipes that use foods I already really like has been helpful too. I just browse say, chicken recipes anything in it I don't like I wont save. It helps to keep the food enjoyable while still healthy. It kind of feels like you are being naughty even if you aren't!

All and all its seriously hit or miss and a giant roller coaster. If you have insurance that covers it it might help to get a nutritionist. My OBGYN offered to refer me to one and I think I will soon take her up on that offer.

Good luck to you and I hope at least one thing I have said helps!!

Make small changes. Trying a massive alteration all at once is just a recipe for disaster. So I switched to having almond milk on my breakfast cereal. After a couple of weeks I started switching carbs, so instead of pasta I'll have something whole grain or wild rice. Instead of butter I'm using coconut oil or olive oil. I'm also slowly shifting the balance of my plates away from carbs and onto vegetables. But it's a slow process. Take time to retrain your habits and taste buds. Make sure you feel like you're adding more than you take away.
Include little snacks. Before I go to bed at night now I have a Turmeric and almond milk latte and a few pineapple chunks. It feels like a treat :)

I definately fight that battle. It's worse when I'm stressed.

It's different for everyone. For me the transition takes about 6 weeks and I fall off the wagon a couple of times a year. I don't have particularly supportive family so every Christmas and birthday I get tonnes of candy and cake and all of that. Once my sweet cravings are fired up it takes a long time (and usually a full length photo of the subsequent weight gain) to bring myself back down to earth. It gets easier though. The more you change, the better you feel and the more you want to change. I know that when I'm eating clean I will sleep better and feel more energetic in the day. I get fewer headaches. I feel more positive and ready to take each new step.

adding more than I'm taking away sounds a treat too! how long did it take you guys to manage this
