LessWrong's benwr shares key health models: ATP, glycogen, and energy storage
Understand your body's energy systems like a tech stack, from ATP to glycogen.
Deep Dive
Benwr, a LessWrong writer, explains fundamental health models covering nutrition and metabolism. ATP acts as the body's energy currency, while glycogen—stored mostly in muscles and liver—serves as short-term energy storage, typically holding 1 to 3 kilograms of hydrated glycogen (including water) for quick bursts. The piece demystifies how food converts to energy and storage, helping readers derive personalized fitness and diet actions from first principles.
Key Points
- ATP is the body's universal energy currency, like electricity for appliances, derived from carbs, fat, or protein.
- Glycogen stores 1–3 kg of glucose (1 kcal per gram hydrated) in muscles and liver for short intense efforts.
- Benwr's practical routine: log food for protein and energy, lift weights at home, measure progress, and walk daily.
