Carol Vorderman hasn't weighed herself for two decades.
The 58-year-old star has revealed she only takes notice of her "dress size", and hasn't bothered to check how much she weighs since before the turn of the century.
Speaking on ITV's 'Lorraine' as part of the 'Body Confidential' series on Thursday (04.07.19), she said: "I haven't weighed myself since 1999.
"I don't actually know how much I weigh and I don't care because I go on my dress size, thank god for lycra! I'm probably about a size 8 to 9 at the moment.
"I've always had a small waist, I think I'm about 25 inches around my waist. If I put on a bit of weight, I know I have, and I go up to a size 11. A larger size 10, that's kind of my boundary for where I'm happy."
When it comes to staying in shape, the former 'Countdown' presenter revealed she loves to go hiking, and walks 12 to 20 miles twice a week.
She added: "In terms of squats, or the equivalent of squats, I probably do over 20,000 a year... that's a lot"
Carol also opened up on how her body has changed over the years, especially during the meopause.
She explained: "As you go through the menopause things change. I had what's called a mirena coil. I put on a stone in two weeks.
"It gives off hormones as well, so I had it removed and it took me a year to lose the weight. I went through this terrible hormonal depression, and I don't use that word lightly, it really was awful."
Watch 'Lorraine' weekdays on ITV from 8.30am to 9.25am.
