HELP WANTED -am I on the right track....?

I've been on the Medifast diet - it's one of those meal replacement diets. You eat 5 of their low cal low carb meals and one "lean and green meal" a day. Daily intake was between 800-1000 cal and 80-100 carbs (below 85 carbs to put into ketosis) daily. - the first time I did this, a few years ago, went from 250 to 185/190 and kept if off for a while. I started Medifast again when the scale read 240 in Feb. 2012 to finally get to my goal weight of 150/145. Although, I have been some-what successful, going from 240 to 215, I think that this is just not the plan for me at this point in my life. I want to do a life style change and Medifsat is just a temp fix. I've decided to return my shipment and start on a journey fit for me and my lifestyle. I have learned a lot from Medifast and I plan to incorporate what I've learned - keeping my food lean and green.

I have an idea of a plan that I've thought about initially starting with, but am looking for suggestions.

I know that MFP says I can consume up to 1200 cal a day and the carbs seem high, but I suppose that will come in handy when working out. I want my 1200 cal to be good, healthy, clean cals. I am still planning on incorporating meal replacement shakes for an easy on-the-go/no-brainer meal - probably spiru-tein mixed with soy milk- and I think I am going to cut out fruits in the beginning due to the fact that they turn into sugar and what not - but then again, is it that bad if I am still in my cal range? - this is where I need to separate myself from the very strict Medifast diet. I am also going to cut out the breads, pastas, and all of the high carb goodness that gets me in trouble.

I am going to eat every three hours - breakfast, snack, lunch, snack, dinner, snack.

Am I on the right track....am I overthinking this.

Let me know your input?

Thanks!
