extreme diet begins today

I have been on and off of diets all year... would start off with a bang, just to fail. well.. I am to the point that if I do not do something drastic then I will never change. so with the help of God I am going on a fast. I need to fast anyway because of some serious needs in the lives of some of my students, and I know we are not supposed to mix dieting with fasting, but as I fast today for Summer Maples surgery, I also plan on shocking my body into a purging mode that I can rid myself of bad habits and get out of the binging mode. My body is a temple of the Holy Ghost and I have abused it with too much pampering of satisfying the taste buds and comfort foods. Well... I already know I am supposed to eat Tuna Salmon and Eggs, nuts, fruits and veggies and drink water and pure juices. but I have been eating processed foods, candy, cake, etc.... I have broken down my temple and for that have gained so much weight, been suffering from back pains, very out of shape and just flat out miserable. I am trusting God to help me use good wisdom and to not cave in to temptation. Tonight is the awards ceremony and I know there will be food there. If I really have my mind made up to fast, then I will stay away from it. I will need willpower. In Jesus' Name!
