Lost 43 pounds in a little less than 6 months. Walk intensely 4 or 5 miles a day for 4 or 5 days per week. Overall walking about 6 to 7 miles per day except on weekend.
No longer eat fast food. Other than that no huge change in diet (though I find I don’t need to eat as much as I used to like to eat...hmmmm).
I’ve lost a lot of weight by adopting a walking regimen. Eventually however, your body’s metabolism will adjust to the walking and the weight loss will level off. So every now and then, I’ll “reset” my body by being totally inactive for a month or two. I try to time that in the middle of winter!
