I do. I eat 5 - 6 cups a day. And I'm 35-40 lbs over my goal and 45-50 lbs over 'normal' weight for my height.
There is NOTHING wrong with me physically. My diet is chock-full of heathly clean pure, often home-grown, foods. I exercise regularly. I'm not yet at menopause.
A little over a month ago, I got a device to tell me exactly what I am burning (with some error, of course). Turns out, my body is extremely efficient. If civilization comes to an end and there is no more food around, I'll be the one to survive.

I burn very, very few calories in a day. Very few. It's now obvious to me why I had to eat less than 1000 calories a day to see weight loss just a few years back. It's also why I am struggling so much with getting back on board to do it again. It's HARD and frankly, I'm being a winey baby.
It's great when people suggest giving up soda, eating fruits and veggies, avoiding fast food, working out regularly, parking far away from stores, taking the stairs, lifting weights, wearing a HRM, setting goals, tracking food, weighing food, blah, blah, blah, blah, blah. Contrary to popular belief, it is possible to be doing ALL of this stuff and STILL not lose weight.
