I feel like I have tired everything too. Finally, for the very first time I feel like I have the answer. I would suggest that you read "It Starts With Food" by Dallas and Melissa Hartwig. It has truly changed my life. No more cravings for sweets and empty carbs. I've been doing Whole 30 and eating as much of the suggested foods as I want and the weight keeps dropping off. I was one of those sweet then salty eaters and could go back and forth all day long without feeling full. Also, I would suggest watching the documentary "Fed Up" ... it is great to see the reason behind the weight issues. I'm still not exercising as much as I should but I am working up to it.
