Nutrisystem waste of money bro! if your going to go that route, just go to to walmart and get healthy choice meals... same idea, far less in month cost.
check out p90x.com get this... trust me follow the program, bust your ass and don't cheat yourself. I wouldn't be shocked if you lost 50 pounds in 90 days! I only wanted to lose 15 pounds and up my core strength for a police academy physical test.... in 30 days barely on the diet program just working out with the program, I lost 15 pounds! by the 5 weeks, I had to double up meals because I was getting too skinny. I stop the diet program after 8 weeks and just ate somewhat healthy and at the end of the 90 days I had lost 17 pounds of actual weight, but look like I added 15 more in muscle... was dope... the program is hard so it's something you have to go balls out and do your very best every day to get the results.
hope that helps,
