Be sure to count those liquid calories, especially if you like to drink the booze.
I've lost 80 lbs in less than a year (from 260 pounds down to 180), primarily by abstaining from alcohol (I was a heavy drinker - a 5th of Bacardi, 750 ml daily with 2 liters of Diet Coke), and instituting regular moderate exercise (walking a minimum of 1-1/2 miles every day, and playing 1-2 hours of doubles tennis 3-4 times per week).
I want to get back into bicycling, but I am still recovering from a fall that injured my tailbone about 3 months ago...
Oh yeah, I have eliminated almost all fast food from my daily intake, and I have cut way back on a few things I enjoy (such as pizza), by coming up with recipes that incorporate many of the same ingredients prepared in more healthy ways.
I'm gradually moving more towards a more vegetarian diet, although I will always be a vaginatarian, 'cuz I do like to eat pussy.
Bon apetit
