The Nutrition Guide
The biology under cravings, hunger, blood sugar and weight, and what to build once you understand it.
Health is a system.You can engineer it.
We look at sleep, stress, movement, hydration, and nutrition as one connected system. Find what is limiting it, change that one part, and measure again.
01How it works
Steady across all five beats perfect in one.
What is missing is rarely information. You have read the articles and run the plans. What you have never had is a way to move all five pillars at once without any of them slipping back.
Perfect one, then the next
Each fix costs you the last one. You end up with one good pillar and four that slipped back.
A little across all five
Nothing is perfect and nothing slips far. Every pillar gets topped up before it can slide, and the total is higher.
Perfect one and the rest slip
Pour everything into nutrition and your sleep drifts. Fix sleep and training goes quiet. Each win is paid for out of the last one, which is why the fourth restart begins lower than the first.
The five pull on each other
Short sleep and a heavy stress load change how hungry you feel and how much energy you have to spend. That is why a nutrition plan built on its own keeps coming apart in the same place.
A little across all five holds
Small, steady moves on every pillar add up to more than one perfect pillar and four neglected ones. Nothing is at its best, and nothing is sliding.
The app names which one to touch
It reads the week you actually logged and picks the one thing worth changing next, so you are never guessing which pillar is holding the rest back.
The clinical programs run the same way and are built to work alongside your clinician, never instead of them.
02The app
Nine programs, one membership, one app.
The weekly report
One change a week, and the reason it picked that one.
Every week the app reads what you logged: food, sleep, movement, water, stress. It picks the one thing worth changing next week and tells you why it picked it.
The week that fell apart is an input to it rather than a verdict on you. Nothing resets and you never go back to week one.
Food, logged and planned
Log it however it actually happened.
Our recipes, your own foods, a single ingredient, or a quick manual entry when you are out. Your day shows against your plan as you go.
Fill a week from hundreds of recipes, swap any meal you do not fancy, and the shopping list rebuilds itself around what you changed.
03How a season runs
The shape of it, over a season.
Where you start
An honest read of where you are now and which pillar is least stable. Then one target worth working toward this season, rather than a list of everything you should fix.
What the first week asks
Run the plan inside your actual week and log what happens. Food and training go in, and the day shows up against the plan. Nothing about the first week needs a clear diary or a perfect run at it.
What the app does with what you log
The nutrition engine reads your logged week and shows you the updated figure rather than holding you to the one you started with. The weekly report reads the same week and picks the one thing to change next, with the reason it picked it.
The week that goes wrong
It will. Work lands on top of you or someone at home gets sick, and the plan you wrote on Sunday stops describing your life. Here is the part no plan you have run before had: you do not go back to the start. The loop reassesses and returns you to the target with a smaller plan sized to the week you are actually in.
What happens after the goal
One membership opens all nine programs, so you move between them without buying again. Most people move onto Maintenance once the thing they arrived for is done.
04The community
Somewhere to land the week it goes wrong.
Isolation is what turns one missed day into a dropped habit. The community is where you post the real week rather than the highlight version, and hear back from the person who built the app.
The free tier is open to anyone. No card at signup and nothing that quietly upgrades itself. Membership is what opens the app, and it sits visible next to the free space rather than hidden behind it, because price should not be the reason somebody never starts.
05Who built this
Keith is an engineer. Energy systems first, then biomedical.
He went back for a Master's in Applied Sport and Exercise Nutrition after years of reading health advice that told people what to do and never why. He wrote the From Resistance to Resilience books for the same reason.
My Health Engineer is that approach built into an app. Look at the whole system, find the part that is limiting you, and change that one first.
Not a doctor, and not a substitute for one. Everything here is built to work alongside your clinician.
06Where this started
Two books came first.
The From Resistance to Resilience series is where the method was worked out on paper. You do not need either one to use the app, and the app does not assume you have read them. They are here because people keep asking where the thinking came from.
The Lifestyle Guide
Sleep, stress, movement and hydration. The four pillars underneath that decide whether the nutrition holds.
You are not starting again.
You are joining a plan that expects the bad week and already knows where you pick it back up. Nine programs across the five pillars, with one app reading the week you actually logged.
