Energy Balance Explained
Energy balance describes a straightforward concept: the relationship between calories consumed through food and calories expended through activity and basic bodily functions. This is the foundation of how body weight changes over time.
Understanding energy balance helps explain why body weight fluctuates based on eating patterns and activity levels. It is not a value judgment about eating habits, but a description of how bodies process energy from food.

Myth vs. Reality
Food myths often suggest certain foods are universally "bad" or "good," but reality is more nuanced. Nutritional value varies based on overall diet patterns and individual circumstances.
Some foods people assume are problematic are actually normal parts of varied diets in the UK and elsewhere. The science shows that dietary diversity and moderate portions matter more than categorizing individual foods.

Metabolism Basics Without Hype
How Bodies Use Energy
Metabolism describes the processes by which the body converts food into energy and maintains basic functions. Individual metabolic rates vary based on body composition, activity level, and other factors.
