I have Before-before pictures of my heaviest weight. (almost 40lbs more than when I started IP) and then, the day I started IP I did the "biggest loser" type photo with the spandex shorts and sports bra (for my eyes only!). One front, one side shot. My daughter has been taking the pictures of me, each month anniversary of the diet.
I have 3 photos so far...and boy see it in a photo is WAY better than seeing it in person in the mirror. You just can't see the difference when you "see" yourself every day. I'm glad I'm doing this.
And then I take pictures when I have a reason to dress up in new, smaller clothes. I have our family Christmas photos (I started the diet on 12/26) and then I have me dressed up for a Valentine's brunch for my writer's group. The next "nice" picture will be my brother's wedding in May.
