WHAT IT’S REALLY ABOUT
Why calories mislead: food quality, biology, labels, and cravings matter
- Calories aren’t a “myth” in physics, but they’re a poor health guide because the body extracts usable energy differently depending on macronutrients, fiber content, and food processing.
- Protein and fiber raise the body’s energy cost of digestion/metabolism and improve satiety, while ultra-processing and heavy cooking often increase calorie availability and make overeating easier.
- The obesity rise accelerated from the mid-1980s alongside cheaper calories, bigger portions, and escalating convenience (drive-thrus to delivery), shifting diet quality downward even when total intake isn’t obviously higher.
- Weight regulation is strongly biological (roughly 40–70% heritable), with genes influencing appetite, efficiency, and fat storage patterns, while environment and socioeconomic status heavily shape outcomes.
- Practical nutrition improvements come from reading labels beyond calories—focusing on protein, fiber, and sugar—and using behavioral strategies like “out of sight, out of mind,” craving planning, and weekly (not per-item) thinking.
IDEAS WORTH REMEMBERING
5 ideasCalories are an imprecise metric because “usable” calories vary by food type.
Your body must spend energy to digest and metabolize food, and that cost differs by macronutrient and structure; two items with the same label calories can deliver different net energy and health effects.
Protein is consistently under-accounted on labels due to its high metabolic cost.
Yeo claims that for every 100 calories of protein consumed, only about 70 are usable because ~30% is lost as heat during processing—making “protein calories” meaningfully different from fat or sugar calories.
Fiber is a double win: fewer absorbed calories and better appetite regulation.
Fiber (from plants) increases the energy required to extract calories and slows sugar release; Yeo recommends roughly doubling typical intake (e.g., aiming around 30g/day vs ~15g average in the US/UK).
Ultra-processing and extensive cooking often increase calorie absorption.
Mechanically/industrially breaking food down (or cooking longer) makes nutrients easier to access—illustrated with corn (cob vs tortilla) and the idea that heavily cooked/processed meals can yield more accessible calories than minimally processed versions.
“Healthy” is context-dependent—athlete, child, and sedentary adult need different things.
Energy needs and what counts as “healthy” vary by age, activity level, and health status; the same easy-to-metabolize calories can be helpful in clinical settings but harmful in a sedentary environment with abundant food.
WORDS WORTH SAVING
5 quotesBecause your brain hates it when you lose weight. You're fighting biology.
— Giles Yeo
But I think today, the major issue to my mind is not the quantity, it is the quality.
— Giles Yeo
So for every 100 calories of protein you eat, pure protein calories, we are only ever able to use 70 calories. Seven zero. So protein counts are 30% wrong everywhere.

Do you know what these things are called? Within the, within the field of, of sort of food science, these are called incidental virtuous foods.
— Giles Yeo
The reason these drugs are good is because they're powerful and they work. The reason these drugs are bad is because they're powerful and they work for everybody.
