I can think of no good reason for you to know what you weigh when it triggers you so much. if you weigh above X, you'll panic and lose. If u weigh below Y, you'll be tempted to lose more. Just let them take care of the numbers.

As for not seeing you when you are below a certain weight, I've never understood that It seems like that's when u need support the most!
