Well, I'm very late to this thread, (and been scarce 'round these Tele parts lately) but here's my story:
43yrs 5'8, was up to 228 back in early May. Decided I had to do SOMETHING, thought I'd give Atkins another go. Started that, just the eating part, haven't exercised to any degree in years. Lost about 15 lbs by Mother's Day. Monday after Mother's Day I had a heart attack. Mild, according to the Doc (it's always "mild" when it's someone else!

), they did a heart cath, and told me I had blockage in several spots, but the good news was I didn't permanently damage anything, and it was all reversible with proper diet and exercise.
Starting then, I've let go the fried stuff, the high fat stuff, the sweet stuff, and started exercising. I'm down to 194, feeling better than I have in a LONG time, and hopefully when I go in for a checkup next week my levels will keep the Doc from hollerin at me.
Anyway just thought I'd share with you guys. Lots of you have been at this a while and I congratulate you for stickin to it.....I'm motivated; hopefully you won't get that same motivation!
