It's funny, even in my teens, I weighed a good 1.5-2 stone more than all of my friends. At the time I thought I was fat because of this, when in actual fact I was so skinny, and in some cases skinnier than the friends who weighed less. I am tall and so I know that accounts for some of it, and I used to do lots of sport so I know (now) that I likely had more muscle mass than my peers. However that number on the scale always led me to believe that I was inferior, because it was higher.
This is part of the reason that I've decided not to focus on losing any more weight. Because I know I am a healthy weight, even though I still weigh more than my friends (even those that look the same as me and may even wear bigger sized clothes).
I can still make positive changes with exercise that may not show in the scale, but are just as important. My body may change in shape and size, I will be healthier, but I will still weigh the same.
We need to focus on our own journeys when we compare, it's about what WE achieve not about what other can do or have done. Losing 5 stone is amazing, but just making the decision to be healthier and seeing that through is equally as amazing regardless of the number on the scale today, or in a month's time or in a year.
For every maintain there is fat that we HAVENT GAINED. In today's society not gaining fat is an achievement on its own!
