Energy Balance and Human Energetics
The Science of Metabolism, Calories, and Body-Weight Regulation
About this volume
Energy Balance and Human Energetics is Book F1 of The Performance & Human Physiology Encyclopedia — a 93-volume, university-level library on the metabolic first principles every nutrition decision rests on. It is written for dietitians, nutrition students, coaches and anyone managing their own body: deep enough that a professional already trained in the field keeps learning, structured clearly enough that a motivated reader can follow every step.
How this book is written
- University level, without dilution. Exact scientific terminology, defined at first use — mechanisms, not just conclusions.
- Evidence graded, not asserted. Major claims carry a level, from A (strong) to D (expert opinion), so you always know how much weight to give them.
- Numbers, formulas, worked examples. Reference ranges, equations and solved calculations you can apply the same day.
- Myths confronted directly. Where a popular claim does not survive the evidence, the book says so — and shows why.
- Fully referenced (APA 7). References at the end of every chapter, plus a master bibliography.
