A DOCUMENTARY slammed by the Australian Medical Association is coming to a Toowoomba theatre.

Celebrity Chef Pete Evans' documentary The Magic Pill explains how his paleo diet can combats illness through eating.

But earlier this month the Australian Medical Association slammed the documentary, with president Dr Michael Gannon saying elements of the discussion were "just plain hurtful, harmful and mean".

The Magic Pill follows people suffering from different chronic illnesses who adopt the ketogenic high fat, low carb diet for five weeks and are all shown to drastically reduce their symptoms and reliance on pharmaceutical drugs.

"What if most of our modern diseases are really just symptoms of the same problem," the synopsis said.

"The Magic Pill follows doctors, patients, scientists, chefs, farmers and journalists from around the globe who are combating illness through a paradigm shift in eating.

"And this simple change - embracing fat as our main fuel - is showing profound promise in improving the health of people, animals and the planet."

Screenings of The Magic Pill will happen through online site Fan Force.

It will screen at the Toowoomba Strand on Wednesday, September 13 at 6.30pm if 41 more tickets are sold before September 1.
