Your resting metabolic rate accounts for more than 60% of daily energy expenditure — far more than exercise.

New research suggests that it may be influenced by an unexpected source: your gut bacteria.

🧵 Historical data indicates that our resting metabolic rates have declined ~6% since the 19th century.

A new clinical trial tested whether probiotics could influence resting metabolism.

The approach: pair Bifidobacterium animalis with inulin fiber—its preferred food source.

Does feeling mildly cold make us eat more?

And if so, do we burn enough extra calories to make up for it?

A new intervention study sought to answer these questions.

🧵 Researchers had 47 participants each spend four separate 24-hour periods in a metabolic chamber - a specialized room that precisely measures energy expenditure.

How long does it really take to form a new habit?

New research challenges the popular '"21-day rule" and reveals the actual science of habit formation.

Let me break down the findings from this month's systematic review and meta-analysis: 🧵 You've probably heard it takes 21 days to form a new habit.

This idea traces back to Maxwell Maltz's observation, in 1960, that plastic surgery patients took ~21 days to adjust to their new appearance - an observation that morphed into conventional wisdom about habit formation.
