I can wholeheartly relate to the stronghold and rebellion. May days I will eat unhealthy just to be able to call it a holiday and eat like my flesh wants to. But there comes a reckoning time. Listen as God speaks. He knocks at your hearts door to give strength to overcome. I firmly believe that strength acts out first in the mind, then the flesh. Have a mind set that you are going to please God with your eating patterns and the flesh will be defeated. Sugar from carbs and processed food is the strong hold. Cut it completely out of your life. You will have so much power revealed to you if you do this. I'm praying for you.
