The books
From Resistance to Resilience
Two books on rebuilding a body that responds. The series unpicks why your body holds on to weight, fires cravings at you and runs out of energy, with insulin resistance at the centre of that story. Then it builds the food, sleep, stress, movement and hydration systems that turn it around.
The research focus behind them is blood sugar and insulin resistance, with specific attention to how women's hormones shift the picture across life phases. That focus became the five-pillar method, and later the app.
01One method, two books
The split follows the work.
Your body runs as one system, and the method treats it as one. The two books split it where the work splits. The Nutrition Guide takes the pillar where change shows up fastest: food, and the metabolic machinery underneath it. The Lifestyle Guide takes the four pillars that decide whether the food work holds: sleep, stress, movement and hydration, plus the deeper biology they all answer to.
They were written to reinforce each other and can be read in either order. Each one stands on its own.
02The Nutrition Guide
The food and metabolic system. Half method, half cookbook.
You have tried diets and watched them fail. The Nutrition Guide starts with why: the biology behind cravings, hunger, blood sugar and weight, and the role insulin resistance plays in all four. Then it turns the biology into a system you can run, from the layout of your fridge to the plan for your week.
Read it once for the mechanism. Come back to each chapter as a working playbook when life shifts and the plan needs to shift with it.
The method, chapters 1 to 6
- Understanding insulin resistance. What insulin does, what makes resistance worse, how it shows up in women, and why most diets miss the mark.
- Blood sugar, cravings and sleep. Why cravings are a chemical echo of the blood sugar rise and fall, and the two meals that matter most.
- Hunger hormones. Leptin, ghrelin and GLP-1, and how to use food to work with them instead of against them.
- Your food environment reset. Why environment beats discipline, from the fridge and pantry to the feeds on your phone.
- Macro mapping and meal planning. Your daily targets and the personal plan you build from them.
- Preparation for success. Prep styles, smart kitchen setup, and removing friction from the week.
The cookbook, chapters 7 to 12
Six chapters of recipes: breakfast, lunch, dinner, sides, condiments and sauces, snacks and desserts. Every recipe carries storage guidelines and reheating methods, because the method assumes batch cooking and real weeks.
03The Lifestyle Guide
The four pillars underneath nutrition, and the biology they answer to.
Nutrition only carries you as far as the pillars underneath it. The Lifestyle Guide is the systems book for sleep, stress, movement and hydration, the four levers that decide whether everything else holds.
It opens with the biology most plans skip, then rebuilds each pillar as its own reset: where you are now, what the mechanism says, and what to change first.
Part one, understanding your biology
- Inflammation. The inflammation and insulin resistance cycle, the hidden triggers that feed it, and how to cool it.
- Detoxification. The myths cleared out, how your detox systems actually work, and what happens when the pathways clog.
- Environmental toxins. Where they hide, how they block progress, and the small changes with the biggest impact.
- Women's hormones. Why women's biology responds differently, including how insulin sensitivity moves across the menstrual cycle and life phases.
Part two, rebuilding your health pillars
The pillars that hold you, then a full reset chapter for each one.
- The sleep reset. The foundation the other pillars depend on: mechanism, leverage, and what to fix first.
- The stress and nervous system reset. Regulation as a daily practice rather than an emergency measure.
- The exercise reset. Movement and training as metabolic inputs you can tune.
- The hydration reset. Fluids and electrolytes as a load-bearing input, not an afterthought.
- The advanced nutrition reset, with a supplements appendix to finish.
04The honest fit
Who these books are for.
For you if
- You have tried plans that worked until life got loud, and you want to know why.
- You want the mechanism, not another set of rules to follow on trust.
- You keep getting advice that ignores what your hormones are doing.
- You would rather redesign the system around you than fight yourself every evening.
Not for you if
- You want a quick fix, a set of hacks, or a one-and-done diet. The books ask you to change small everyday things and let the results accumulate.
- You need contest or peak-performance programming.
- You are looking for medical treatment. The books are education and structure. They complement your clinician and never replace them.
05The author
Written by an engineer who had to fix his own health first.
Keith Young trained as an engineer before he trained in nutrition. A degree in energy systems engineering and a Master's in Biomedical Engineering taught him to treat a struggling system as a design problem. A family history of heart disease and a motorbike accident that forced a long recovery made his own body the system that needed the work.
A Master's in Sport and Exercise Nutrition added the biology, with research focused on insulin resistance and women's metabolic health. The books condense almost fifteen years of study and lived experience into a method you can run in a normal week.
06Questions
Asked before buying.
Do I need the books to use the app?
No. The app does not assume you have read them, and nothing in the membership is gated behind them. The books are where the method was worked out in full. The app runs the method for you, week by week.
Which book should I read first?
Either order works, they were written to reinforce each other. If food, cravings and blood sugar are the fight in front of you, start with the Nutrition Guide. If nothing sticks no matter what you eat, start with the Lifestyle Guide, because the reason usually lives in sleep, stress, movement or hydration.
Are these diet books?
No. Neither book hands you a meal plan and wishes you luck. The Nutrition Guide explains the biology driving cravings, hunger and blood sugar, then builds your food environment and meal system around it, with six chapters of recipes to run it. The Lifestyle Guide covers the four pillars underneath, because nutrition only holds when they do.
Are the books only for women?
No. The biology applies to everyone. The books give specific attention to how women's hormones shift insulin sensitivity across the menstrual cycle and life phases, because that is where the research focus was, and it is the part most books skip.
