I really, REALLY hate the stupid Windows functionality that makes backspace go back a page. WTF.
Anyway... starting over.
You guys a bunch of lightweights.
No seriously, look at your progress and you should be amazed that you've had such an easy time with it. I'm 6'3" and in May, I was 432#. Very tall for the weight, but also very heavy obviously. My ideal weight is actually very close to what was considered your overweight weight (275 is almost just "overweight" for me)
Most people overestimate the value of resistance training too. Cardio is good for keeping things revved up, but our bodies actually use more resources when they have to rebuild muscle from resistance training.
A program I got involved with back in May of this year had me start out at 432 lbs, and after 10 weeks, I only lost 5 lbs, but I also lost 10% of my body fat because I was working out 6 days a week (45 minutes a day) 3 days cardio, 3 days resistance. The even more amazing thing is that I'm eating more during the program than I would otherwise. Wait, what? Yeah, my thinking was totally wrong in the regard. My goals are in the neighborhood of 72 grams of carbs, and 34 grams of protein PER MEAL. It's a staggering amount of food, but I have to tell you, when you increase your activity, you have to make sure you're well fueled to make up for it. The amazing thing is that this program has folks coming in from the local military bases in my city, and they take the 10 week course, and improve their physique over what even their daily PT in the military does. It's really amazing to see these already fit or "average" folks come in wearing their camo or uniforms and leaving 10 weeks later looking like a body builder. It's just insane. and amazingly, works well for a lot of people. Their slogan is "results are typical" and after seeing the difference in my before and after photos, you bet your cookies it is. lol
If you're curious, I'm pretty sure it's a USA only thing, but having been on the "diet this way" bandwagon for most of my adult life and never getting anywhere (even though you have been! Congrats!) it's never a bad idea to look out there and see if there's something else that can help move along. If you can build lean muscle mass, your idle calorie usage goes up, and you burn even when you're not working out.
