Anyone here doing insanity?/Old medifast user

Hi, Ive been on and off MFP for about a year. Was very active on here while I was on medifast which was about a year ago. I was successful with it (45lb loss) but slowly started to put the weight back on once I stopped. I realized after getting off I didn't really know how to cook healthy for the whole day! I can make a mean salad though! (What my Lean & Greens mostly consisted of lol) It did actually taught me a few tricks though, like the 0 cal. Walden Farms products which I still use today and how important it is to add greens to your diet daily. But this time around I'm not going to go the meal replacement way but rather looking at the ingredients of products and staying clear of the overly processed foods. I am also currently doing Insanity for the first time! On day 5 which is the Pure Cardio Day (intense!) and I was wondering if there were any fellow members on here currently doing insanity? or have done it in the past and can shed some guidance on your experience with it?

Also I'm also just looking to find friends that are trying to improve there eating habits and trying to shed the pounds for summer!
Best of luck to everyone,
Eleana
