Danielle Lloyd has stunned her followers by revealing a rather dramatic body transformation after gaining weight over the Christmas period.

The 37-year-old star took to Instagram on Thursday to share epic before and after pictures of her physique and revealed she has shed an impressive 5lb in just 10 days.

In the snaps on the left, Danielle is wearing a white bandeau top and black and grey leggings as she shows off her figure at all angles.

In the after pictures, she dons a white Nike sports bra with black leggings as she flaunts her flat stomach and trimmer waist.

Danielle Lloyd has unveiled her dramatic body transformation on Instagram

She captioned the post: "Actually feel embarrassed posting these before pictures I really did let myself go in December.

"I joined @miss.ketones 10 day challenge and these are my results!!

"Am so pleased although I’ve only lost 5lb on the scales you can see from my pictures my shape has changed dramatically."

Danielle continued: "It was so easy 2 ketone drinks a day and eat as normal. I lowered my carb intake to get the best results possible but I did little to no exercise.

Danielle told her followers she has lost the weight doing a 10-day challenge after letting herself go over Christmas

"The keto diet is great but hard to sustain, so these exogenous ketone drinks are perfect to get your body into ketosis without the diet.

"Ketosis is where your body uses your fat as a fuel, hence the quick fat loss. Other benefits include energy, better sleep and better mental clarity which is something I think we all need right now!"

The mum-of-three is certainly not shy when it comes to showing off her body

The former glamour model added: "Am going to start another challenge on Monday as I want to continue to feel amazing and better myself if anyone wants to join me check out @miss.ketones now and DM them for a discount code. #missketones #exogenousketones #10daychallenge."

Danielle's 544k followers were quick to like and comment on the Instagram post, with one person writing: "Smashed it."

Another added: "Boom! Well done Danielle! Looking ripped!" and a third wrote: "Amazing..just needs to be more affordable."

Danielle recently admitted that her husband Michael O'Neill doesn't want her to have any more cosmetic surgery

Others were quick to urge Danielle not to feel embarrassed about her before pictures.

"I think you looked great on the 4th too. But it’s whatever you are happiest with that really matters," one commented.

Her transformation comes after she told Closer magazine that her husband Michael O’Neill won’t let her have any more cosmetic surgery.

"[Michael] said, 'I just don't want you putting us through this any more'," she admitted.

"Surgery can be a slippery slope and can be really addictive."

Danielle has had boobs jobs, as well as surgery on her nose and a bum lift.
