The TV presenter, aged 62, gained some weight after she turned to comfort eating during the Covid-19 pandemic.
Lorraine took the selfie with Celebrity Ambassador Coach Suzy Stirling, who also shared snaps of it to her platform.
Lorraine captioned the post: “Feeling great! Happier and healthier! Lost over a STONE and confidence returning!”
Suzy also shared a snap of Lorraine holding up the card as she stood in the living room.
“AMAZING!!! Well done Lorraine… How do you feel?”
Fans were impressed with her weight loss and took to the comment section to compliment the TV presenter.
“Well done Lorraine, ur an inspiration,” one user said while another added: “You can see it ! Lorraine honestly you look so good xx.”
One impressed fan commented: “Well done! I’m a big fan of WW after losing 5 stone with them.”
“Wow that’s amazing. is that watching food and increasing exercise x,” another added.
She previously opened up about her weight gain as well as her journey to lose it again.
“During the pandemic, I started comfort eating and that was my downfall – comfort eating and not being able to go to my fitness classes,” she said.
“When those classes stopped I started eating far too much – it was things that I would probably never bother with. Like I wanted muffins, I wanted croissants, I wanted doughnuts.
“All of these things that you know you shouldn’t be having and you think it’s making you feel better at the time and it doesn’t. And so slowly, slowly, slowly over the past couple of years, I’ve gone from a size 10 to a size 14…”
She realised she gained weight when she tried on one of her go-to red dresses and realised she no longer fit into it.
“I looked absolutely fine, but I didn’t feel fine,” she said of having to wear a different dress.
