Do you often wake up feeling tired, struggle with persistent bloating, or find yourself more sensitive to stress than ever before? If you’re in your 40s or beyond, it’s easy to blame these symptoms on age or hormones alone. But as Dr. Betty Murray and functional medicine expert Laura Frontero revealed on a recent episode of the Menopause Mastery Podcast, the reality is far more complex. Midlife energy issues are rooted deep in the body’s “terrain”—a dynamic system shaped by gut health, mitochondrial function, detoxification, and nervous system balance.

Let’s explore what’s really going on within your cells, why classic advice may not always help, and the practical, step-by-step strategies to help you feel like yourself again.
It’s Not Just Your Hormones—Cellular Health is Key
Hormones are vital, especially during menopause and perimenopause, but as Dr. Murray explains, “hormones can only do so much.” The powerhouse behind your energy isn’t just your estrogen or thyroid—it’s your mitochondria, tiny structures within nearly every cell that generate energy from the foods you eat. Hormones influence how effectively these organelles function, but imbalances in your gut and buildup of toxins can cripple your body’s ability to maintain cellular energy.
Laura Frontero reminds us, fatigue is “the smoke signal from the body that your mitochondria are starting to decline.” This means those sluggish mornings, afternoon crashes, or total lack of motivation are more than missed sleep or stress: they’re often signs that the body’s energy factories—and the environment they exist in—need support.
Why Fixing The Gut Comes First
Gut health is foundational to overall wellness—and nowhere is this more obvious than in energy regulation. However, Frontero cautions that many people focus exclusively on “bad” bacteria rather than the bigger picture. Your digestive environment, or “terrain,” is what dictates which microbes thrive and which cause problems. If your immune system and digestive processes are out of balance, simply taking probiotics or attacking unwanted bugs with herbs rarely delivers lasting results. In Frontero’s words: “The bacteria… live there for a reason. And the reason is your terrain is screwed up.”
Restoring the gut’s integrity and function—especially making sure you’re eliminating waste regularly (yes, daily, healthy bowel movements!)—sets the stage for everything else. Only after this internal clean-up should you target stubborn bacteria or yeast with eradication protocols.
The Great Diet Debate: Why “One Size Fits All” Doesn’t Work
Midlife women are bombarded with stories of miraculous healing from extreme diets, whether carnivore, keto, or vegan. But, as both podcast experts emphasize, therapeutic diets are meant to heal a specific issue in the short-term, not serve as a lifelong template. The celebrated bacteria Akkermansia muciniphila—essential for gut health—thrives only in the presence of plant-derived polyphenols, which carnivore diets lack.
The solution? Eat for diversity and seasonality. Your optimal fuel source shifts with health status and genetics, and most women need a mix of animal and plant foods, especially as they age. Frontero sums it up: “The diet that heals you is not the diet that will sustain you.”
The Critical Link: Gut Health, Toxins, and Energy
One of the podcast’s most eye-opening revelations is the relationship between toxins, gut infections, and the immune system. Your gut isn’t just for digestion—it’s a crucial site of detoxification. Toxins from the environment (think heavy metals, plastics, and mold) encourage the growth of stubborn infections like Candida and H. pylori by providing them with a protective niche. When your system is overloaded, it can even “make a deal” with these bugs, letting them stay as long as they mop up dangerous toxins.
This means your “gut cleanse” will stall unless you also address the underlying toxin load. Regular detoxification, especially once you’ve restored healthy digestion and elimination, is essential for making lasting improvements in energy and resilience.
Mitochondrial Support: The Anti-Aging Foundation
Every beating heart, every clear thought, every cell repair relies on the energy produced by your mitochondria. With age, exposure to toxins, stress, and chronic gut issues, mitochondrial numbers and effectiveness plummet. This isn’t just about how you feel today—chronic depletion in these organelles underlies almost every serious age-related disease, from Alzheimer’s to heart disease.
Supporting mitochondrial health doesn’t just mean taking a supplement. It’s a daily practice that includes:
- Nutrient support: CoQ10, magnesium, B vitamins, and polyphenol-rich foods
- Detoxification: Regular binding and elimination of environmental toxins
- Movement: Gentle exercise and lymphatic flow (think dry brushing, walking, or rebounding)
- Hormone support: Restoring balanced hormones as needed to optimize cellular communication
The Right Sequence: Where to Start for Real Results
Jumping straight to an extreme diet or gut-killing protocol can backfire, often making people feel worse before better. Dr. Murray and Laura Frontero agree on a smarter order:
- Restore elimination. Regular, complete bowel movements—ideally producing 12-18 inches of stool daily—prevent recirculation of toxins and set the foundation for healing.
- Support liver and lymphatic detox. Use herbs and bitter foods (arugula, dandelion, quality coffee) to get these waste-removal pathways moving.
- Nourish mitochondria and balance the terrain. Build from the ground up using a mix of nutrition, gentle supplementation, stress management, and movement.
- Target infections and stubborn imbalances. Only once digestive flow and cellular health are restored should you address chronic infections directly.
Maintaining Your Progress: The Value of Ongoing Support
After healing the terrain, it’s critical to maintain your gains. Both Frontero and Murray practice daily mitochondrial support and periodic detoxification—not because they’re unwell, but because today’s world is more toxic than ever. Maintenance isn’t a failure; it’s the key to sustained energy, graceful aging, and protection from disease.
Reclaim Your Energy: What Next?
Feeling tired, sluggish, and overwhelmed isn’t inevitable in midlife—you can take action. As Laura Frontero shares, “right now is the time” to start supporting your mitochondria, your gut, and your hormonal health—no need to “earn” further intervention. For those seeking a deeper dive, Frontero’s robust free resource, The Midlife Energy Crisis, offers detailed explanations and actionable steps.
With the right approach, you can move from exhaustion to vibrant living, no matter your age, phase, or starting point. You don’t have to settle—your best energy years can still be ahead.
