I weighed in on Wednesday morning (June 13) @ home: 274.6, a gain of 3 1/2 # from last week (271.0). (Because of a cold and a sore knee I'd been slacking off my aerobics for a few days.) On Thursday afternoon (June 14) I had a doctor appointment; they weighed me there and the reading on that scale was 272.2, still a gain from last week but not nearly so bad.
My question: how much faith should I place in my at-home scale? Might it need new batteries? It's a Weight Watchers digital model which I bought in April 2006 when I started my diet (we have another analog scale @ home but it only goes up to 280# and I was over 300 when I started); I take it into another room to weigh in because that room has a hard floor while my bedroom has a shag carpet.
