Is loosing 3 pounds a week unrealistic for someone who is exercising 4-5 times a week?

You rock! Keep up the great work! I workout in the pool 4-5 times a week. I can burn so many more calories than on the treadmill!

I don't think it's unrealistic but it's on the high end...

It really depends on your body, everybody is different. For me, I do kickboxing 6 days a week and eat 1200 or less calories and I'm ecstatic if I lose 2#/ week

Thats fantastic I excercise 7 days a week cardio and 3 days strength eat under 700 calories a week-I was losing 4-5 lbs a week but have slowed to and 2lbs a week 9which I am told is normal but darned I would like it to be more

I was SMO when I started.. and only walking.. and lost 4lbs a week at first.

The more weight that is lost, the slower it comes off. As I get closer & closer to goal, it becomes more difficult.
