I’m Kristin Uppal, founder of Vitaliat and a Certified Holistic Health Practitioner, Metabolic Balance® Coach, and Wellness Educator with over 20 years of experience in fitness, nutrition, and health coaching. My own health journey taught me that true wellness goes far beyond calories and exercise — it requires addressing the whole person: mind, body, and lifestyle. That’s exactly why I created Vitaliat: to help people cut through the confusion, understand what’s actually happening in their bodies, and build sustainable habits that support vibrant health for life.
Understanding the Everyday Habits — and Hidden Hormonal Shifts — That May Be Depleting Your Energy
You slept. You had your coffee. You’re doing all the things you’re supposed to do. And yet — by 10am, you’re already running on empty.
If chronic fatigue has become your baseline, you’re far from alone. Persistent low energy is one of the most common concerns among adults over 35 — and one of the most frequently misunderstood.
Tiredness is too often dismissed as laziness, over-scheduling, or “just getting older.” But the truth is that fatigue is a signal. It’s your body communicating that something in your internal environment needs attention.
Here are 7 real, evidence-based reasons your energy may be draining — and what you can do about each one.
Energy Is a System, Not a Single Switch
Before diving in, it’s important to understand that energy is not produced by one organ or controlled by one hormone. It’s the result of multiple systems — nervous, endocrine, digestive, cardiovascular, and metabolic — working in coordination.
When even one of these systems is under strain, energy suffers. Often, it’s several at once.
7 Reasons You May Be Chronically Tired
1. Poor Sleep Quality (Not Just Quantity)
Most people focus on how many hours they sleep. But research increasingly shows that sleep quality matters as much — if not more — than sleep duration. Fragmented sleep, light sleep, or sleep disrupted by cortisol, blood sugar fluctuations, or hormonal changes may leave you exhausted despite spending 7–8 hours in bed.
For women in perimenopause and menopause, declining progesterone (which has a natural sedative effect) and night sweats frequently devastate sleep architecture. This is one of the primary reasons fatigue skyrockets during hormonal transitions.
What helps: Consistent sleep/wake times, reducing alcohol and caffeine after noon, managing blood sugar before bed, and addressing hormonal contributors if relevant.
2. Chronic Stress and Elevated Cortisol
Cortisol is your primary stress hormone — and it’s also deeply tied to your energy cycle. In healthy patterns, cortisol rises in the morning (giving you that get-up-and-go energy) and falls toward evening. Chronic stress disrupts this rhythm.
When you’re under persistent stress — whether from work, relationships, health concerns, financial pressure, or simply the relentless pace of modern life — cortisol patterns become dysregulated. The result: feeling “wired but tired,” difficulty falling asleep, fatigue that doesn’t respond to rest, and a reduced ability to handle even small stressors.
What helps: Identify your main stress sources. Build genuine recovery into your daily routine — not just passive scrolling, but actual nervous system regulation through sleep, movement, nature, breathwork, or social connection.
3. Blood Sugar Instability
One of the most common — and most overlooked — causes of chronic fatigue is blood sugar dysregulation. When you eat high-glycaemic meals, skip meals, or rely heavily on caffeine and sugar to get through the day, your blood glucose spikes and crashes repeatedly.
Each crash triggers a stress response (a small cortisol release), leaves you shaky and foggy, and signals the brain to demand more quick fuel. Over time, this pattern contributes to insulin resistance, increased inflammation, weight changes, and compounding fatigue.
What helps: Build every meal around protein, fiber, and healthy fats. Don’t skip meals, especially breakfast. Reduce reliance on caffeine and sugar as energy substitutes.
4. Inadequate Protein Intake
Protein is not just about muscle. It’s essential for neurotransmitter production (including serotonin and dopamine — your mood and motivation chemicals), immune function, hormone synthesis, blood sugar regulation, and cellular repair.
Many adults — particularly women — chronically under-consume protein. The commonly cited RDA of 0.8g/kg is widely considered insufficient for active adults or anyone over 40. Research now supports aiming for 1.6–2g per kg of body weight for metabolic, hormonal, and cognitive health.
What helps: Include a quality protein source at every meal. Eggs, Greek yogurt, fish, legumes, chicken, and high-quality protein supplements can all contribute. Spreading protein across meals matters more than any single high-protein meal.
5. Hormonal Shifts — Especially in Perimenopause and Menopause
If you’re a woman between roughly 35 and 55 and fatigue has crept in alongside other changes — irregular periods, sleep disruption, mood shifts, weight changes, or decreased libido — perimenopause may be a central factor.
Declining estrogen affects mitochondrial energy production, serotonin regulation, thyroid function, and insulin sensitivity. Declining progesterone affects sleep quality, anxiety levels, and nervous system regulation. The cumulative effect is profound fatigue that lifestyle changes alone may not fully resolve — but significantly improve.
What helps: Support your hormonal transition with targeted nutrition (especially protein and healthy fats), strategic movement (strength training is critical), stress management, and ideally, guidance from a practitioner who understands perimenopause well.
6. Dehydration and Low Electrolytes
Even mild dehydration — as little as 1–2% of body weight — has been shown to impair cognitive function, reduce physical performance, and increase perceived fatigue. Many people move through their days in a state of chronic mild dehydration, relying on coffee (a diuretic) as their primary fluid.
Electrolyte imbalances — particularly low sodium, magnesium, and potassium — can compound this, affecting nerve conduction, muscle function, and energy metabolism.
What helps: Drink water consistently throughout the day. Consider adding electrolytes, especially if you exercise or sweat significantly. Magnesium in particular (often depleted by stress) plays a key role in sleep and energy.
7. Insufficient or Wrong Type of Movement
Counterintuitively, both too little and too much exercise can cause fatigue. A sedentary lifestyle reduces circulation, impairs mood regulation (by limiting endorphin and BDNF release), disrupts sleep, and lowers energy capacity. But excessive high-intensity training without adequate recovery — particularly under chronic stress — can deplete your adrenal and immune reserves.
For adults over 35, the research strongly supports strength training as the highest-return movement investment: it improves insulin sensitivity, supports bone density, preserves muscle mass, boosts metabolism, and meaningfully improves energy and mood.
What helps: Move daily, but intelligently. Prioritize 2–3 strength sessions per week, supplement with walking, and honour recovery as part of your training — not an absence of it.
When Fatigue Signals Something More
Lifestyle optimization can achieve a great deal — but persistent, severe, or worsening fatigue should always be evaluated medically. Thyroid dysfunction, anaemia, sleep apnoea, autoimmune conditions, and other health factors can present as fatigue and require clinical assessment.
Don’t normalize exhaustion. Explore it.
Frequently Asked Questions
Sleep quality, blood sugar instability, chronic stress, hormonal imbalances, dehydration, and nutritional gaps can all cause fatigue despite adequate sleep hours. The cause is usually multifactorial and worth investigating systematically.
Yes. Hormonal changes during perimenopause — particularly declining estrogen and progesterone — directly affect sleep, energy metabolism, mood regulation, and mitochondrial function. Fatigue is one of the most reported symptoms of hormonal transition.
A whole-food diet centred on protein, fiber, healthy fats, and micronutrient-dense vegetables supports blood sugar stability, hormone production, and sustained energy. Specific nutrients — omega-3s, magnesium, B vitamins, iron, and vitamin D — are particularly relevant for energy metabolism.
Signs that stress is a primary fatigue driver include: feeling “wired but tired,” difficulty winding down, poor sleep quality, irritability, increased cravings, tension headaches, and fatigue that worsens with additional demands.
Yes. Protein is essential for neurotransmitter production, hormone synthesis, blood sugar regulation, and cellular repair — all of which affect energy levels. Chronically low protein intake is a common and underappreciated fatigue contributor.
