"The before photo stigmatized as bad and the after good for dropping weight? This isn't sending the wrong message to people?"
Nope. The before picture is someone who was, unhappy, in pain from just walking, comfort eating, pre diabetic, stopped taking part in life/enjoying clothes. The after picture is someone who has achieved a very difficult goal, in some cases, have beaten one of the hardest addictions.
I've been miserable for three years because of my weight. I'm now using VLC products. I have to log into FB daily, sometimes hourly to keep going.
Seeing before and after pictures has helped immensely. Taking them has helped. A lot of us stop looking in mirrors. We throw on leggings and tunics etc.
What has been a big help is seeing the pictures and journeys of Women, like myself, with health issues who are 50+.
Many obese people go into denial that's there's a way out. Pictures are real evidence that there is.
I've lost two stone and I'm looking ok, got my face back etc, but this is the time i usually slip back. The pictures are there to stop that. We're having a weekly Christmas count down. 2lb a week weight loss is two stone by Christmas. Many of us vow every year to not be the size we are next Christmas/New Year, but we are, but we don't have to be.
