This thread is inspiring, great job guys.
I've been as heavy as 280, this was back in 2007. A more active job helped me slowly drop some pounds and in summer of 2009 at around 240 I decided to get serious about weight loss. Completely changed my diet, started a walking program. I walked EVERYWHERE, was doing an average of 7-8 a day with some longer 12 mile walks 2 times a week. That slowly transitioned into a running addiction. By September I was down to 190. Went down to the gym to run on the treadmill all winter, 3 times a week. My miles slowly increased, was doing 7 miles at a time by February. I couldn't run a 12 minute mile in highschool but by April 2010 I was doing 40 miles a week at 7:30 min per mile. At my lowest I was around 168 by summer 2010. This was probably way too skinny for my frame (6'4)
An injury stopped me from running but I bought a bicycle and started lifting weights. After 6 months I had put on a bit of weight, but was building muscle too. Back up to 185, mostly good weight. Mostly stuck around that weight for around a year and a half. This past December I got hit by a car and broke my leg. My diet turned to SHIT. I ordered pizza 3 times a week, ate out constantly, lots of sugar and carbs. My weight is around 205-210.
I'm back on the horse, this is day 9 of my diet. Looking forward to it warming up finally. I'm going to approach this the same way I did 2009, starting all over. Lots of walking, hope to start running once I get the OK from my doctor. Its definitely possible, this thread is proof of that. ANYONE is capable of the kind of amazing change you see in this thread.
