231: Winter Metabolic Strategies
Winter has its own special and distinct impact on our biology. The seasonal changes in our environment cue some very specific physiological processes in our body, especially our mitochondria which run our metabolic process.
In this week’s podcast episode we’re talking about how 3 major zeitgebers - light, temperature and food - affect our mitochondria at this time of the year. Winter is the time for more darkness, more melatonin, more cold and more fats. This means less light, less Vitamin D, less warmth and less carbs. Come listen to this “In Relation to Creation” episode to learn more about God’s fascinating design of our body!

EPISODE 231: Winter Metabolic Strategies
EPISODE BLOG
Hello, my friends! Today, I'm eager to share insights on Winter Metabolic Strategies. If you've never considered how seasons affect metabolism, you're in for an enlightening journey!
Understanding Metabolism in the Winter Context
Metabolism, often misconceived as merely a determinant of body weight, is fundamentally about energy production. It's a 24/7 process involving every cell and organ in our body. The liver, adrenals, intestines, brain, thyroid – all depend on efficient metabolic functioning.
Our mitochondria, those tiny powerhouses in our cells, are incredibly sensitive to environmental changes. They constantly monitor external conditions to adjust energy production, ensuring our survival. This adaptation is a divine design, showcasing the brilliance with which our bodies have been crafted.
The Role of Light in Winter Metabolism
Winter brings shorter days and longer nights, which significantly impacts our biology. The decrease in daylight is a powerful zeitgeber – an environmental cue that influences biological rhythms. This seasonal change prompts our body into a mode of repair and restoration.
Melatonin: The Nighttime Hormone
Melatonin, stimulated by darkness, is a crucial hormone in this process. It signals our bodies to detoxify, repair tissues, and rejuvenate. Conversely, cortisol, the daytime hormone, is stimulated by light, particularly blue light.
The modern challenge is the artificial blue light from screens and bulbs, which confuses our internal clock. It inhibits melatonin production, depriving us of crucial repair and detoxification time. Therefore, managing light exposure is vital for winter wellness. Using amber-colored blue light blocking glasses in the evening can be a practical solution.
Vitamin D and Melatonin: Seasonal Hormone Partners
Vitamin D and melatonin work in tandem across seasons. While Vitamin D, produced in response to sunlight, dominates in summer, melatonin takes precedence in winter. This natural cycle is critical for maintaining balance in our anti-inflammatory processes.
The Sun's Role in Vitamin D Production
Vitamin D from sunlight is superior to supplements. Sun exposure triggers the production of sulfated cholesterol, which transforms into natural Vitamin D. This form is more bioavailable and beneficial compared to its supplemental counterpart.
Subcellular Melatonin: The Mitochondrial Power
Beyond the brain, our cells also produce melatonin, particularly in response to near-infrared light. This form of melatonin aids in continuous cellular maintenance, complementing the intensive nightly repair work.
Food as a Seasonal Zeitgeber
The food we eat in winter should reflect the season. Winter's reduced availability of plant foods naturally shifts our diet towards higher fat and lower carbohydrates. This aligns with our body's preference for burning fat for energy during colder months.
Seasonal Eating for Mitochondrial Efficiency
Eating seasonally ensures that the light codes embedded in our food match the environmental cues, thus aiding our mitochondria in efficient energy production. For instance, consuming watermelon in a Minnesota winter disrupts this alignment.
Embracing the Cold: A Winter Imperative
Cold temperatures are a critical zeitgeber. Exposure to cold activates brown fat, which is essential for thermoregulation and efficient fat burning. Avoiding over-regulation of indoor temperatures and embracing the natural cold can boost our metabolic health.
Fasting in Winter: A Natural Rhythm
Historically, winter was a time of less food availability, making it a natural season for fasting. Fasting aligns with shorter daylight hours and taps into stored energy (fat), thus supporting our metabolic processes.
The Importance of Grounding and Light Exposure
Regular exposure to natural light and grounding (connecting with the earth) are crucial, even in winter. They provide essential cues for our circadian rhythms and support hormonal balance.
Conclusion: Respecting Nature's Design
Our health is intricately linked to the rhythms of nature. By understanding and respecting these natural cycles, particularly in winter, we can optimize our metabolic health. As we marvel at the divine intricacy of our bodies, let's commit to aligning with the seasons for our well-being.
Remember, health is more than just diet and exercise. It's about understanding and honoring the complex interplay between our bodies and the environment.
I hope this exploration of Winter Metabolic Strategies has provided you with valuable insights. Embrace these natural rhythms and thrive in harmony with creation's design!
