The Good Morning Britain star spoke on-air about her training for the new series of the BBC show, revealing that she has lost half a stone since she started preparing for the dance competition.
The conversation began when the presenter's co-stars Susanna Reid and Piers Morgan commented on Ranvir's new look.
Susanna said: "My goodness, you look like you've been in a training room, working hard!"
Ranvir asked: "Are you saying I look a bit slimmer?" To which Piers replied: "You do look slimmer!"

The star then confirmed that she had lost weight, saying: "To tell you the truth, I weighed myself this morning, and I have lost half a stone!"
However, Ranvir told viewers that they shouldn't follow her regime as she said anxiety was preventing her from consuming any hearty meals.
"I am so scared, I can't eat," she said, adding: "I am eating loads of fruit and stuff."
Susanna was sympathetic, chiming in to say, "It suppresses your appetite."
Piers, meanwhile, teased Ranvir that she was a bit too energetic for his liking.

He joked: "You've got that rather unfortunate extreme energy that everyone off Strictly gets."
Ranvir responded: "It's the adrenaline, I kid you not!"
Piers went on: "The old sparkle comes on, and you all basically go a bit nuts and spend your whole time bouncing around.
"In my dressing room, you get the feed before you come on air, and Ranvir was practising for her half-hour news slot, and I could see she just wanted to dance!"
She'll have her chance before long – Strictly's launch show is this coming Saturday, with the first live edition being broadcast on 24 October.
Earlier this month, the star shared one of her preparations for the series – getting her footwear ready. She posted a hilarious photo of her feet on Instagram, which showed Ranvir wearing her strappy gold dancing shoes with a pair of black socks!
Hopefully they'll be comfy enough to wear without the socks very soon…
