Fuel crafted to your ambition.

Train hard. Eat well. Less to work out.

KEXBI is a tailored nutrition app that works out your fuelling needs, then calculates amounts of the foods you prefer and usually stock. Its Chef creates meals from those ingredients and quantities, shaped around your tastes and kitchen.

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

THE INGREDIENTS AND THE CRAFT

Why this meal

This breakfast is shaped around muscle repair, morning energy and comfortable fullness. KEXBI draws on your own pantry, the foods you prefer and usually stock, and calculates their amounts for your needs at that moment. The Chef creates the recipe from those ingredients and quantities, shaped around your tastes and kitchen.

Greek yogurt
Provides protein to support muscle repair as part of the breakfast’s 29 g protein.
Oat flakes
Provide carbohydrate for morning energy, with fibre that can slow digestion and help sustain fullness.
Blueberries 98 g
Contribute carbohydrate alongside the oats, bringing fruit and fibre into the morning’s fuel.
Raw walnuts 20 g
Supply fats that can slow how quickly the meal leaves the stomach, helping the breakfast feel more sustaining.

ITS PLACE IN YOUR DAY

Why it matters

The aim at 08:00 is to support muscle repair, fuel the morning and keep you comfortably full without feeling heavy. The foods and their amounts are brought together around that purpose, so the breakfast supports the body as well as fitting the day.

YOUR KITCHEN. YOUR CHOICES.

You choose.
You shop. You cook.

Your food choices.

Your pantry holds the foods you prefer and usually stock. KEXBI works out the amounts to meet your fuelling needs, then the Chef creates the dish using those ingredients, your tastes and your kitchen. You keep the choices, do the cooking and enjoy the food.

Changes you review.

When KEXBI suggests a change, see the reason and decide whether to apply it.

Logging is optional.

Your plan is ready to follow. If you choose to record food and weight, enough consistent history can help refine it.

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.”
