THE ORIGIN

I couldn't afford a nutritionist. So I built the plan I needed.

I wanted more from the work I was putting in. The training was planned. The food was still mine to work out.

I had every number. Why couldn’t any of them tell me what to eat?

I’ve got calories to hit and macros to balance. But what goes on my plate? How much? And when should I eat around training? I’m chasing numbers down to zero, while every food decision is still mine.

JANUARY 2011

162 kilos. Smoking 20 cigarettes a day.

01

Looking back, I must have been eating well over 5,000 calories a day. Vast portions, convenience food, and sweets and snacks between almost every meal. At work, my nickname was “Uncle Buck”, after John Candy’s character. A reference to my size. My body fat was over 40%. I was morbidly obese and unhealthy. But the effect went beyond my health. I avoided photos. I avoided holidays. Without really recognising it at the time, I was making choices around my size, quietly narrowing what I allowed myself to do. I was disappearing from my own life.

02

The turning point wasn’t a calculated health plan. It was a midnight impulse. After seeing a deeply confronting family portrait, I did something desperate. I entered a 10K. I didn’t own trainers. I didn’t know what a “macro” was. I just knew there was no way out.

03

I dressed in head-to-toe black and only ran when it was pitch black outside. That first night, I managed two miles. Short runs became long runs. Over the next few years, everything changed. But as my distances grew, I hit a completely different kind of wall.

04

I was data-rich, but insight-poor.

05

I had the heart to run 100 miles, but I didn’t have the fuel. I stared at heart rate monitors and sleep scores, but none of it told me what to eat.

06

So I built the system I couldn’t afford.

07

A system that reads your body and your training, and works out food for the week ahead, with each day shaped around its training and routine, so you don’t have to. Today it is the engine inside KEXBI.

THE MISSION

What if the science reached all the way to your plate?

A nutritional target is a starting point. KEXBI carries the working through your day: what each meal needs to provide, when it belongs, and the ingredients and amounts that meet the brief. The chef turns that brief into food.

For the lifter building muscle, the runner chasing a quicker Parkrun and the person losing fat while fitting training around work and family. Different ambitions, different days, and food shaped around the person living them.

THE STANDARD

What checks sit behind the food?

The plan is checked against its targets and planning limits. Open the working to see how energy, protein and hydration are considered, and where a constraint or shortfall is recorded.

FUELIs there enough fuel for training?
PROTEINIs there enough protein to adapt?
HYDRATIONIs there enough water for the day?

TODAY

Why I keep training.

Since that first two miles: ten trail ultramarathons, fifteen obstacle races, twenty 10Ks and ten bucket-list adventure races. Venice Marathon is next, then Mount Fuji.

The portrait that started this was of my family, and they are still the reason. Movement is not a means to an end in our house, it is just how we live. My boys run with me now. They train. In 2027 they take on Mount Fuji themselves. Health is wealth, and it has added life to my years.
