MOBILE phone carrying cavemen are coming to the Sunshine Coast.

They won't, however, be staying with dinosaurs at the Palmer Coolum Resort.

Instead, the 20 people booked so far for the Paleo Cave Camp will pay $1270 to stay in dormitories at the Apex camp at Mudjimba this weekend.

The paleo menu includes "pulled pork bowls with roast sweet potato, paleo slaw and apple sauce" followed by "blueberry and lemon 'cheese' cake".

And the attendants will be encouraged to learn primal moves, including walking on all fours and jumping like a kangaroo.

While the cave people might not have shoes, expect to see their mobile phones.

The paleo show co-ordinator Steven Hayter explained the new phenomenon used social media to spread its message.

"We don't take people's phones away, it is how they document their experience," he said.

The Palaeolithic diet, which encourages the types of eating you would have expected in the Croods or the Flintstones, is becoming increasingly popular across the world. More than 1000 people already "like" the Sunshine Coast Paleo/Primal/Real Food Meet-up Facebook group.

Mr Hayter said this was the first time a caveman camp was coming to the Sunshine Coast, with these kinds of events launched in Adelaide in May.

"About 90% of the people coming to the Sunshine Coast are people coming back from the first one," he said.

At first glance, the weekend might seem expensive, but Mr Hayter said it was about providing people with the skills to last a lifetime.

"It is an investment in yourself. It is a catalyst experience which gives the nuts and bolts of how paleo works."

The diet has attracted at least one high-profile critic: Dr Karl Kruszelnicki. He said it didn't weigh up. We had evolved quite a lot from what we were 12,000 years ago, he said.
