I am 5 ft 11in tall and have a large frame. When I told my close friends what I weighed when I started on this (298#) they didn't believe me. Me and my best friend started together and when I got on the scale she almost fell over. But she is much smaller too, she only needs to loose about 30 pounds. So maybe the perspective is the difference I don't know. The look of disbeliefe on peoples faces is funny when I say "29# down and 94# more to go". But even tho I don't look what I weigh (269# at present) I'm keeping focused on my goal of 175#.
