The Metabolic Switch - Fields, Grace

. .

Résumé :
Most people think metabolism is about speeding up calorie burn, but the real secret lies in training your body to become adaptable. When your system can switch seamlessly between fuel sources, protect muscle during scarcity, and use energy with precision, you gain a level of freedom that no diet or quick fix can match. This is the science of metabolic flexibility training-and it changes everything about how you eat, move, and recover. This book delivers a clear, research-driven guide to reshaping your energy system so it works for you, not against you. Instead of rigid rules or fad diets, it offers practical strategies for aligning nutrition and movement with how the body truly functions. You'll learn how to balance fasting vs fueling, use nutrient timing for workouts to your advantage, and apply resistance training for metabolism so you preserve lean muscle while burning fat. Inside, you'll discover: - How to improve insulin sensitivity and restore your body's ability to access stored energy - When performance nutrition timing matters most-and when it doesn't - Why carb cycling and strength training can expand your energy capacity without overcomplicating your diet - Simple methods to avoid over-fueling while still feeling strong, clear, and focused Designed for athletes, professionals, and anyone seeking lasting health, this book reframes metabolism as a trainable system rather than a number on a calorie counter. By the end, you'll hold a new model for energy use-one that helps you sustain performance, protect muscle, and achieve genuine metabolic health without fear, fatigue, or constant food obsession....
