HPN Textbook

The Most Comprehensive Encyclopedia on Modern Performance Nutrition Globally

Backed by more than two decades of K11’s scientific legacy

For the first time, K11 School of Fitness Sciences presents a 4-module, 791-page authoritative textbook series, Human Performance Nutrition Textbook, that decodes performance nutrition with scientific clarity, practical frameworks, and real-world applications.

Built on the philosophy of our Principal, Mr  Kaizzad Capadia – “Science begins when myths are questioned” – this book brings together everything a fitness professional, athlete, or coach needs to understand the body, fuel performance, and transform outcomes.

The Importance of the Human Performance Nutrition Textbook

Because today’s world is drowning in fad diets, shortcuts, influencers and guesswork.

This book restores science, logic and truth to nutrition.

You’ll learn:

  • How the human body actually works
  • What fuels performance at a physiological level
  • The truth behind macronutrients, micronutrients & hormones
  • How to plan diets for goals, body composition & performance
  • Evidence-based science behind supplements, recovery, hydration & trends

What is Inside the 4-Module Set of the Human Performance Nutrition Textbook?

Module 1: Core Science of Performance and Nutrition – Human Body, Vital Systems & Macronutrients

7 Chapters | 253 Pages

Overview

A deep foundation in human physiology, including vital body systems and macronutrient metabolism.

Key Insights from This Module

This is where you stop “following” nutrition and start understanding it.

Module 1 breaks down the human body, its fuel systems, and its nutrient requirements, much like an engineer’s blueprint.

What You’ll Discover

  • How the body’s vital systems actually regulate energy, recovery & performance
  • The real science of proteins, fats and carbohydrates – not the Instagram version
  • What macros do inside your body at rest during workouts and during recovery
  • Why athletes perform differently based on their biochemical design
  • How poor macronutrient understanding leads to fatigue, plateaus & metabolic stress

The Value of This Module

If you don’t understand Module 1, you cannot design performance nutrition. This is your foundation – whether you want to help fat loss clients or elite athletes.

Module 1 Preview Edition – Understanding Carbohydrates: Monosaccharides to Polysaccharides

Module 2: Applied Physiology and Nutrition Science – Hormones, Hydration & Micronutrients

8 Chapters | 222 Pages

Overview

Learn everything the industry misunderstands about Calories In Calories Out (Energy balance model), Body Composition Regulation & Testing, Hormones in-depth, Energy systems & Performance, Water and Electrolytes, Vitamins and Minerals in depth.

Key Insights from This Module

The most successful people excel because they deeply understand the role of hormones, hydration, vitamins & minerals and not because they try hard. This module changes that – forever.

What You’ll Discover

  • The science behind body composition beyond “calories in vs calories out”
  • How hormones (insulin, cortisol, thyroid hormones, growth hormone, testosterone & estrogen) actually influence recovery, muscle growth & fat loss
  • How hydration impacts strength, stamina, mood & performance
  • Understanding the complete metabolic pathways of vitamins & minerals
  • Early signs of micronutrient deficiencies and performance drop

The Value of This Module

This module allows you to design nutrition that works in harmony with the body, not against it.

For trainers & nutrition aspirants, this is what separates “generic programs/diet plans” from “science-backed coaching/nutrition plans”.

5 Chapters | 138 Pages

Overview

This science-led guide covers practical nutrition applications from diet models and evidence-based supplementations – including amino acid & performance-boosting aids – to hunger and satiety hormones, strategic nutrition planning and understanding popular diets & trends.

Key Insights from This Module

This is where theory becomes actionable nutrition mastery.
