Hi ,well what I would do is weigh your self at home if you feel that your scale is weighing rite tell the doc that you would rather it be that way and they should respect that ,but i bet that the scale would go high enough.and I think you would be really suprised about your doctor being supportive my doctor was great if he is negative remind him that this is the same diet they tell diabetics to follow .Well let me know and good luck .
