Winter Sluggishness? Uncover the Real Science Behind Your Metabolic Shift

  • Winter sluggishness isn't a direct metabolic slowdown but stems from lifestyle changes influenced by colder weather.
  • Reduced daylight disrupts circadian rhythm, lowers Vitamin D, and increases melatonin, leading to fatigue and decreased activity.
  • Decreased non-exercise activity thermogenesis (NEAT) due to cold weather significantly lowers daily calorie expenditure.
  • Diet shifts to calorie-dense comfort foods, coupled with inadequate protein, micronutrients, and hydration, impair metabolic efficiency.
  • Prioritizing protein, micronutrients, consistent sleep, morning sunlight, and hydration is crucial for maintaining metabolic health in winter.

Why It Matters: Winter's impact on metabolism is due to lifestyle shifts, not inherent slowdown; conscious choices are key.
