What it's for

The results you're training for.

The PB you keep just missing. The body comp you're working toward. The energy for everything after training. Get the fuelling right, and the training you already do starts showing up.

Chrononutrition

Anyone can hand you a number. KEXBI tells you when.

Other apps hand you one daily number and leave the rest to you. KEXBI schedules your food around your training, from the meal before to the refuel window after. Then it scales back when you rest. Same food, timed around training. That is chrononutrition.

We do the timing. You get the time.

No counting

We did the counting. You just eat.

Most apps give you a number and make you count your way to it. KEXBI turns that number into real meals from your own kitchen, portioned and timed around your training, so it already adds up. Nothing to tally, nothing to log: you just eat. You control the pantry: it is your food, your likes and your dislikes, and KEXBI learns as you go. Weigh in regularly to let the trend keep it honest, and log the detail when you want, because the more you do the sharper it gets.

Built from your own kitchen

Every meal comes from the food you already own, in portions that suit what that food actually is. A drizzle of oil, never a bowl of it.

The week

Plan it once, then leave it alone.

Plan your whole week in about fifteen minutes and prep it in one go if you like. The rest of the week is grab and go.

Every day

Every day built around your training.

Each day is written for the work in it. Hard days carry more and land it around the workout. Rest days scale back. You are not handed the same number seven times.

The food you keep, in KEXBI
Your kitchen

Built from your own kitchen.

Every meal comes from the food you already have, chosen to fit the day's training and the way you cook.

The shop

The shopping list is the plan.

Exact quantities for the week's training, grouped the way the shop is laid out. Prep week, cooking fresh, an Italian week: change how you want to eat and the list is rebuilt around it.

Nothing in the trolley is a guess.

KEXBI flags a short night and offers the change
When it changes

It adapts when your body does.

When a workout runs long or last night's sleep lands short, KEXBI flags the day. One tap shifts your fuel to match the work you actually did.

Slept badly It eases the day's load and sets up a better night.
Trained longer Ran long? It covers the extra.
Moved a workout Move or add a workout and the day re-plans around it.
Energy that lasts

Fuelled for the day, not just the workout.

You don't train for the gym. You train for the day it has to carry: the back-to-back meetings, the 3pm that used to flatten you, the evening you still want something left for. KEXBI fuels the work and the life around it, so you stay sharp long after training is done.

Why KEXBI

Calories aren't enough information.

Most apps hand you a calorie target. KEXBI is built on a fuel database drawn from validated national food databases. Each food is scored for how fast it digests, raw and cooked, and matched to the part of the day it best suits.

You get meals from your own kitchen, not a macro puzzle dressed up as advice. Open the app, and the day's training is already in the food.

Every number has a trail. Open today's plan, tap breakfast, and see why it landed there. See the working →

The wearable gap

Your band knows how you slept. It says nothing about the plate.

Whoop, Oura and Apple Health measure you well. None of them changes what you eat because of it. Slept badly? KEXBI eases the day's load and sets up a better night. It flags the change and offers it. One tap applies it.

Keep the band you already wear. KEXBI reads it and answers the question it was never built to answer.

Is this for you?

Built for people who train with intent.

KEXBI is for people who train consistently, care about the outcome, and want the food to match the work.

Built for you if

You train 4 to 6 days a week and take fuelling seriously
You already track sleep, strain, or recovery
You've outgrown calorie counters and want precision, not averages
You want structured guidance, not generic suggestions

Not for you if

×
You want a basic calorie counter and a rough plan
×
Your training days all ask the same thing
×
You're after a family meal planner
×
You want a crash diet or a quick fix
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, three weeks in
“Even though I'm eating noticeably less I'm full and have a lot of energy still. No dip in performance in the gym, if anything it's improved.
“My weekly shop is about £30 less than it was.”
Luke MastersPersonal trainer · Cohort 001
Same training, eating to the plan rather than a flat daily number. His food changes with the training day.
