If a client was not losing weight, but losing inches, how would you keep the client motivated to stick with you?

I support Angie’s response wholeheartedly. Remember exercise tightens everything up nicely, causing loose clothing and a belt notch change, and of course cardiovascular benefits, but exercise does not support weight loss without caloric restriction. If the client wants more, than he/she has to committ to adjusting food intake. So your next task would be to help her journal or help her strategize a plan to reduce calories bite by bite.
