I dropped from ~270lbs to 233 lbs in 50 weeks by eating less ice cream and drinking wine instead of beer. I also rode my bike regularly, commuting and MTB'ing. I was stuck at 233, even worse, I thought I was 223...my scale was off by 10lbs.
A co-worker told me about calariecounter.com, all I can say is WOW. I was eating ~3500 calories a day and with exercise and my baseline daily burn, I was zero sum, maintaining 233lbs. Hmmm, makes sense to my engineer mind. So I joined the building heath club, $10 one-time fee, elipicycles, treadmills, bikes, Universal. Now I'm eating ~2200 cals a day and burning 1000-2500 cals a day in exercise. Calculates out to about -10,000 cals per week, I've lost 4-5 lbs in the last 2 weeks. If 3500 cals = 1 lbs of fat, I'm losing right at what the Mayo site says I should.
I'm 6-2, 228lbs and now I really believe I can weight 190lbs, I am determined to make my goal. I have given up all the bad stuff, no sugars, deserts, alcohol until I'm 190lbs.
I didn't even think about doing this until I started lurking here, you guys are great!
