65 YR old woman from Pittsburgh. Looking for support losing weight. I have a sedentary job and really need to get losing and get moving. Currently a "Fluffy" 258 pounds. I want to take my Grand Daughter to an amusement park or zoo with out having to rent a scooter to haul my self around. My knees hurt and I get short of breath so quickly. I know a lot of it is from the extra baggage I'm carrying.
