adjusting portin sizes...

Hi Lisa, I am using the nutrition progrAM . It is making suggestion for 200 lb person. I am o.ly 175…it gives me direction to adjust portions if I am less than 200. But does not tell me how to adjust. Can u help me to understand how to adjust portion sizes when needed . I imagine I will need to do.this in the future.as I continue to lose weight as well. Thanks, Shannan
