I have never really been all to concerned with how much I weigh. this is not because I haven't been a little heavier than I am now. In fact, in college, while playing rugby, I peaked at about 225. While I was undoubtedly not in great shape, I obviously was able to at least play well enough to make the second string team.
That said, I use the scales more as a guideline than anything. How I actually feel and whether I like what I look like in the mirror mean far more to me. I think that is a healthier idea of body image and fitness anyway. Even if I did not, I would go crazy trying to figure out my body in any other fashion.
Case in point: while I know I already lose a lot of weight in a marathon, and that my weight fluctuates so much in a day that it is really something for a case study, this week has been quite odd.
Sunday (before the marathon): weight was 171
Sunday (after): 163
Monday Night (remember, my Monday was 12 hours longer than most of yours because of my flight home): 167
Tuesday night: 166.5
Wednesday night: 175
Thursday night: 173
That is really sorta ridiculous when you look at at it all. Not more than a few weeks ago I had been 181. And for the vast majority of Fiddy2 my weight stayed in the mid 180s with it actually hitting plus 190 at times.
Just some food for thought (pardon the pun) on how weight itself is hardly the best indicator of your health.
