Fuel crafted to your ambition.

Train hard. Eat well. Less to work out.

Eating for your goals shouldn’t become another job.

KEXBI is a tailored nutrition app that turns your fuelling needs into food you want to eat. It calculates amounts of the foods you prefer and usually stock, then its Chef creates meals around those ingredients, your tastes and your kitchen.

Meals, drinks and workout fuel are timed around your day, with one shopping list for the week.

Food logging is optional. You keep the choices.

THE INGREDIENTS AND THE CRAFT

Why this meal

The ingredient amounts are calculated together for this breakfast’s planned balance. The Chef turns them into creamy overnight oats, with fruit and walnuts added in the morning. Each food has a nutritional role and a part in the finished dish.

Greek yogurt
Provides protein to support muscle repair as part of the breakfast’s 29 g protein, and forms the creamy base.
Oat flakes
Provide carbohydrate for morning energy and fibre that can help sustain fullness. They soften in the yogurt overnight.
Blueberries 98 g
Contribute carbohydrate alongside the oats, with fruit and fibre. Added in the morning, they bring fresh sweetness to the chilled oats.
Raw walnuts 20 g
Supply fats that can slow how quickly the meal leaves the stomach, helping the breakfast feel more sustaining. Added last, they keep their crunch.

READY FOR THE MORNING

Why it matters

For this 08:00 breakfast, the aim is morning energy and a sustaining meal, with protein to support ongoing muscle repair. Carbohydrate supplies fuel; fibre and fat can help with fullness. Prepared the night before, it takes about two minutes to finish in the morning.

WHY I BUILT IT

I train hard, and I had every number: sleep, strain, weight, every macro. I still didn't have the one answer that mattered: what to eat today to make the work count. Nothing joined the data to the plate, so I built the thing I needed. KEXBI is that answer, for everyone who trains with intent and wants the effort to show.

FROM THE BETA
COHORT 001, ELEVEN WEEKS IN

“Sundays used to go on planning my diary: when to eat, what, how much, and trying to work out my digestion against the intensity of the workout, usually unsuccessfully.

Now the week’s already built. A hectic week in the office doesn’t touch my energy; the mid-afternoon dips are gone.

Eleven weeks in, I’m eating for me, the gym’s up, my body’s building, and the shop’s about £30 a week lighter. If you’re a PT, you and your clients should be on this.”
