Starting fast tomorrow (tonight!)

Hi all,
I really have to do this fast. I start college at the end of August and want to be in good shape, and this may be the longest stretch of time I'll have to do a long fast for a while.
I weigh 239, 5'6. I'm fasting to lose weight, one reason cause I read it results in less loose skin then dieting or restricting, another, is that I ate raw for 2 weeks and had high energy, looked better etc. But I am having the hardest time transitioning to raw foods cause of my junk/processed food addiction, which I'm hoping fasting will cure.
My goal is to fast till the end of July, eat raw for a week, then fast 2 weeks, eat raw through out the school year.
I know this is going to be hard for me, cause it's hard for me to just go raw, so I'm hoping posting about my fasting online like this will help me stay motivated.
