Grant No Longer Has Ulcerative Colitis Symptoms

From Hospital Beds to Ninja Warrior: Grant’s Keto-Carnivore Comeback


A Family Shadow and a Dire Diagnosis

Growing up in Wollongong, Grant watched his father battle bowel cancer and ulcerative colitis until his passing in 2010. Three years later Grant himself was diagnosed with ulcerative colitis, spending three harrowing weeks in hospital as doctors debated removing his large intestine. Medication spared him from surgery, yet life became a cycle of pills, bloating and resignation.


False Starts and the Food Revelation

Determined to improve, Grant tried conventional clean-eating plans and personal training sessions. A meat-and-three-veg approach helped him drop ten kilograms, but believing the hard work was done he slipped back into old habits and the weight—and the bloating—returned. He accepted chronic discomfort as inevitable.


Discovering Keto-Carnivore and the Crucible of Adaptation

Everything changed when a new trainer introduced him to the keto-carnivore diet. Grant immersed himself in research by Shawn Baker and other advocates, committing fully despite feeling awful for three weeks. In the fourth week the fog lifted: diarrhea stopped, headaches disappeared and a profound surge of energy replaced fatigue.


Seven Months of Transformation and Medical Validation

Grant has adhered to keto-carnivore for seven months, allowing only the occasional keto-friendly salad and minimal alcohol. Regular blood tests and an abdominal ultrasound show pristine results. Training up to twice daily, he now holds a stable weight of 72 kg with dramatically reduced body fat and no sign of disease.


Beyond Recovery: Spreading the Message

​With renewed vitality Grant has qualified for the trials of Australian Ninja Warrior Season 5 and plans to highlight keto-carnivore nutrition on the show. As a professional chef, he hopes to teach others to cook real food, abandon excess carbs and sugar, and reclaim health—as he did—through a keto-carnivore lifestyle.

Rowan Improved Cardiovascular Health, Treated Arthritis

After struggling with weight loss and finding keto difficult to maintain, this person discovered the carnivore diet through Shawn Baker's Joe Rogan appearance in December 2017. They lost 36 pounds (from 216 to 180), eliminated arthritis in their left hand (which had a surgically reattached finger), normalized blood pressure from prehypertension, and experienced improved mental clarity and stress response.I was struggling trying to lose weight, and found keto so hard to stick to, so easy to fall off. I heard Shawn Baker on Joe Rogan and decided to look into it. I spent about 2 or 3 weeks checking out the info, and asking people on the Zeroing in on Health forum on Facebook numerous questions. After that, I was convinced it was worth trying keto-carnivore for a month. I began on the keto-carnivore diet on December 12th 2017. I've never even had to consider changing back. I was 216 lbs, and I am now 180. I had arthritis in my left hand, which hand had to have a finger surgically reattached to it after it was ripped off in an accident 13 years prior; but the arthritis went away after 2 weeks keto-carnivore. I had prehypertension, but my blood pressure (measured on three separate occasions) is normal. I feel better, I think clearer, and I respond to stress better than at any time in my life. ​I never intend to stop being a keto-carnivore.
