Weight started coming off but it really accelerated when I got serious about exercising. Swimming a mile 3x per week. Weight training 3x per week, and I've been on the treadmill a lot in the evenings, probably another 15 miles per week fast walking. Down 60 lbs as of now and consistently losing around 3-4 pounds per week.
It's hard to keep calories at less than 1800 per day with all the exercise, but it's just a hard psychological limit I've set for myself and the myfitnesspal app (and a kitchen scale) make it doable.
It seems to me that the exercise has made me lose about 1-2 pounds per week more than just diet, but who knows.
I miss pizza.
