The answer to this will probably depend very much on how long ythe person has been LCing and how much weight they are losing

For me I lost easily to start with and weighed every day. I always saw the scale either stay the same or go down. Once weight loss slowed to about 2-4lbs per month I went to once a week.

now that I am hardly losing/stalled...I avoid the wretched contraption like the plague
