Given the weight on your your tracker, it is not uncommon to lose 4 pounds
in a week, here and there. When I started at 330
lbs, there were
weeks that 4-
6 lbs were lost and I was eating healthy and exercising regularly. However, as wonko said, the more your weight drops the more the weight loss slows and the calories needed to maintain your weight goes down.
Would be happy to help you find the calories needed to maintain your current weight ..
