I started this year as a 270lb 6'2'' planet. Somewhere in the middle of February I started tracking on mfp and dropping lbs quick. Maybe a month or 2 later I bought a fitbit. It was half tech toy, half reminder to make better choices throughout the day. Little things like just taking the long way around places at work, taking the stairs, motivation to run. I'm now 193lbs and still wear my fitbit, I bought the fancy GPS heart rate one to track runs a few weeks ago, after running for 2 months before that. It is what you make it. I told everyone that mfp is awesome if you're honest and slightly over estimate intake. Biggest thing its helped me with is realizing portion and serving sizes. Realizing how much you over eat is the biggest wake up call once you start tracking food.
