An independent editorial record of energy expenditure, adaptive thermogenesis, and the variables that shape long-term metabolic health.
The rate at which the body expends energy at rest represents a foundational variable in long-term metabolic health. These field notes examine what shapes it and how it shifts across a lifetime.
Among the macronutrients, protein carries a distinct thermic burden. An observational account of how dietary composition intersects with resting energy expenditure and whole food metabolism support.
Adaptive thermogenesis describes the body's capacity to modulate energy expenditure in response to context. This entry charts what consistent daily movement contributes to metabolic flexibility.
Staven Almanac was established to document the factors that influence metabolic rate across the adult lifespan — not as a collection of quick observations, but as a sustained editorial record. Metabolic rate and weight are often discussed in narrow terms. The almanac takes a wider view, drawing on peer-reviewed research and evidence-informed approaches to examine how variables like muscle mass and metabolism, meal timing and metabolism, and consistent eating rhythm interact over time.
The publication operates from the premise that calorie awareness and metabolism are subjects worth viewing with editorial rigour. Slow metabolism, when examined carefully, reveals itself not as a fixed state but as a set of interacting variables — among them adaptive thermogenesis, nutrient partitioning, and the thermic effect of food — each of which shifts in response to daily patterns and longer-term habits.
This record is updated quarterly. Each entry undergoes review by a second editor before publication, and sources are cited where appropriate. The editorial principles that govern this process are outlined in full on the methodology page.
