My profile pic is me a few months ago so I had lost a bit of weight but in recent photos I can see the next lot of weight loss. I don't really have any of me at my biggest, I was the photographer as a way to avoid having my picture taken! I will take and upload another one when I have lost another 6lbs as that will be 2 stone lighter than the profile pic.
I do think pictures can be a really useful tool because we look at urselves everyday and can't always see the changes, although clothes getting bigger helps, so to compare pics is a good reinforcement that the hard work is paying off.
