I'M A Celebrity fans have called on Medic Bob to keep an eye on Adele Roberts, as they fear she is losing too much weight on the jungle diet.

Campers have to get by on rice and beans unless they win stars during Bushtucker Trials or Dingo Dollar challenges which offer them treats such as chocolate or a Sunday roast dinner.

However after Adele lost two stone in 2018 when she became unhappy with her health, viewers have now voiced concerns over her ongoing weight loss following only two weeks in the jungle.

One viewer tweeted: "I know Adele was thin going in but she seriously can’t afford to lose any more. Hope medic bob is keeping an eye."

Another added: "If Adele loses any more weight she’ll disappear."

"In all seriousness I hope she’s actually alright, she’s looking extremely skinny!" tweeted a third concerned fan.

Adele had previously revealed her two stone weight loss transformation after giving up sugar.

The Radio One presenter says she "woke the f*** up" and changed her life after reaching 12 and a half stone in 2017.

She swapped chocolate bars for protein bars and replaced white baps for sourdough bread after vowing to shift the weight.

To celebrate losing 28lbs in 12 months, Adele launched a YouTube channel in November 2018 called The Fakeaway Factory Past, Present & Future.

She used a free app online to kick-start her fitness by pledging to exercise seven minutes a day before building up to 10,000 steps and 30 minute workouts a day.

Adele then ended up doing a body building documentary after impressing show bosses who spotted her weight loss journey.

However, on I'm A Celebrity Adele has been forced to break away from her normal diet and try to swallow vomit fruit, turkey testicles and sheep's foot in gruelling Bushtucker Trials.

Show bosses have estimated that each of the initial ten contestants has lost at least half a stone – more than three kilograms – in the two weeks since they entered the jungle.

Temperatures in camp have rarely dipped below 30 degrees with the campmates chugging up to three litres of water a day to stay feeling full.

Campmates have largely been forced to eat just basic rations of rice and beans – getting around just 700 calories a day to eat.
