Science of Diet and Exercise: Nutrition & Physiology Basics

With so much conflicting fitness and nutrition advice available today, it is difficult to separate scientific facts from marketing fads. Understanding the biological mechanisms of how the human body processes food and responds to physical stress is the key to achieving sustainable health goals. This course provides a clear, evidence-based introduction to the biological principles of diet and exercise. You will gain a solid foundation in human metabolism, macronutrients, and exercise physiology, allowing you to design effective lifestyle strategies based on real science rather than guesswork. What you'll learn: - Understand the fundamental principles of energy balance, human metabolism, and daily energy expenditure. - Analyze the biological roles of carbohydrates, proteins, fats, and micronutrients in supporting physical activity. - Explain how the muscular, cardiovascular, and nervous systems adapt to different types of exercise. - Apply scientific principles to evaluate popular diet and fitness trends critically. - Learn behavioral strategies to support long-term adherence to healthy eating and training routines. The course begins with foundational definitions of metabolism and cellular energy before moving into the specifics of macronutrient digestion and muscular adaptation. You will progress through written scenarios and conceptual exercises that help you connect physiological theory to real-world diet and exercise planning. This course is designed for beginners, fitness enthusiasts, and aspiring wellness professionals who want a reliable, scientific foundation without requiring any prior background in biology or chemistry.
