Hi,
I'm sorry you are upset but listen:
Everytime I would start working out I would gain a little weight. I think it is because you are building muscle. That is why your inches may be getting bigger. You need muscle mass to burn calories so this is positive for the long haul. You don't want to starve off the weight you want to build it off. Build a foundation under your weight. Think of a body builder "before" picture.
Overweight people, and I'm including myself here, have big emotional issues, that's why we are heavy. We use food to quell our feelings instead of learning how to manage them. In my experience, it has been better to learn to be assertive. And it is hard because I'm scared to death some one isn't going to approve. Your body is your body and no dietition can predict how it is going to react to this change. Be honest with her, tell her you don't want to feel punished or reprimanded because your body isn't doing what everyone else's does. Put the ball in her court. It is very uncomfortable in the beginning but after awhile you'll get a certain fiendish delight in doing it.
Good luck, Sharon
I'm rooting for you !
