I am a 57 year old female with type 2 diabetes.i have lost about 100lbs. a doctor told me that i wouldnt lose anymore. what r ur thoughts?

Depends: It depends on your current weight and your ideal weight. With diabetes, it's usually not a question of possibility (of course you can lose more) but of safety. Regardless, the closest you are to your ideal weight and the closest you are to a stable normal blood pressure and blood sugar, the better. You may even get to go off your diabetes meds (i've had patients do that).
