If she came out and said
“I had lost weight and was proud of that - which is why I wanted to share a picture. I agree that the way I was standing made my body appear slimmer and more toned than it actually is in real life. I am sorry if I mislead any of you into thinking that is how I look all of the time. Most people when having their picture taken will have a preferred side, or a pose they do, or a filter they use which makes them feel good. I’m no different, I worked a flattering angle, made the most of my body to get the best picture I could! But I accept that as someone who puts themselves out there to thousands of people (some of whom may be vulnerable and impressionable) I should have been more transparent about how much my posture, outfit and lighting affected the overall look of the picture. Rather than it being solely down to my diet and exercise plan”
I’d stop “trolling” her if she said something like that. Not aggressively posting stories lying that she’s being body shamed and refusing to admit she mislead a lot of people.
