Divine Wisdom in Fuel Flexibility
"Whether you eat or drink or whatever you do, do it all for the glory of God." (1 Corinthians 10:31)
When God created our bodies, He embedded within us remarkable metabolic flexibility—the ability to derive energy from multiple fuel sources. This divine design reflects His provision and wisdom, particularly evident in the body's capacity to produce and utilize ketone bodies. Recent groundbreaking research reveals that this ancient metabolic pathway, activated through ketogenic eating, holds extraordinary promise for cognitive health, particularly in the fight against Alzheimer's disease and age-related cognitive decline.
Understanding Ketones: Alternative Fuel for the Brain
Ketone bodies—including beta-hydroxybutyrate (BHB), acetoacetate, and acetone—are molecules produced when the body shifts from burning glucose to metabolizing fats for energy. This metabolic state, called ketosis, occurs naturally during fasting, extended prayer and fasting periods, or when following a ketogenic diet characterized by high healthy fats, moderate protein, and very low carbohydrates.
As the Psalmist declares, "I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well" (Psalm 139:14). The brain's ability to seamlessly transition between glucose and ketones demonstrates this wonderful design—a backup system that ensures our most vital organ never lacks fuel.
Breakthrough Research: Ketones and Alzheimer's Disease
The Glucose Crisis in Alzheimer's
One of the earliest hallmarks of Alzheimer's disease (AD) is the brain's declining ability to utilize glucose effectively. Researchers have observed that even before symptoms appear, certain brain regions show reduced glucose metabolism. This "energy crisis" contributes to the cognitive decline that characterizes the disease.
However, groundbreaking research from the University of Kansas published in 2024 reveals a remarkable finding: while the brain's ability to use glucose declines in Alzheimer's disease, its ability to use ketones remains intact. This discovery opens an entirely new therapeutic pathway.
The KDRAFT Study: Cognitive Improvement Through Ketosis
In the Ketogenic Diet Retention and Feasibility Trial (KDRAFT), led by Dr. Russell Swerdlow and Dr. Debra Sullivan, researchers followed ten participants with mild Alzheimer's disease who adopted a ketogenic diet for three months. The results were striking:
- Cognitive scores significantly improved after the three-month intervention
- Improvements were seen across multiple cognitive assessments including the Mini-Mental State Examination (MMSE) and Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog)
- When participants returned to their normal diet for one month, test scores returned to baseline, suggesting the ketogenic intervention was directly responsible for the improvements
Meta-Analysis Confirms Cognitive Benefits
A comprehensive 2024 meta-analysis published in the Journal of Nutrition, Health & Aging reviewed 10 randomized controlled trials involving 691 Alzheimer's patients. The research demonstrated that ketogenic diets could:
- Improve mental state scores by 7.56 points on average
- Enhance MMSE scores by 1.25 points (a clinically meaningful improvement)
- Reduce ADAS-Cog scores by 3.43 points (indicating better cognitive function)
- Elevate beta-hydroxybutyrate levels by an average of 118.84 μmol/L
The researchers concluded: "Research conducted has indicated that the KD can enhance the mental state and cognitive function of those with AD... the good intervention effect and safety of KD are worthy of promotion and application in clinical treatment of AD."
The BHB Breakthrough
In March 2024, researchers at UC Davis published findings in Communications Biology showing that beta-hydroxybutyrate (BHB) plays a pivotal role in preventing early memory decline. Their study in mice demonstrated:
- BHB levels increased almost seven-fold on the ketogenic diet
- The ketogenic diet significantly delayed early-stage memory loss comparable to mild cognitive impairment
- BHB improved the function of synapses—the critical connections between nerve cells
- Better-connected neurons resulted in improved memory function
Dr. Gino Cortopassi, co-author of the study, stated: "The data support the idea that the ketogenic diet in general, and BHB specifically, delays mild cognitive impairment and it may delay full blown Alzheimer's disease."
Exogenous Ketones: Promising Support
A September 2025 systematic review and meta-analysis published in medRxiv examined the effects of exogenous ketone supplementation (ketones consumed as supplements rather than produced through diet alone). The findings suggest that exogenous ketones could be "a promising adjunctive strategy in dementia management, offering potential benefits even in patients who maintain sufficient carbohydrate intake."
This is particularly encouraging for those who may find strict ketogenic diets challenging to maintain long-term.
Gender and Genetic Considerations
Recent research from the University of Missouri published in October 2025 reveals that the benefits of ketogenic eating may be particularly pronounced in women carrying the APOE4 gene—the strongest known genetic risk factor for late-onset Alzheimer's disease.
Female mice with the APOE4 gene showed:
- Improved gut microbiome composition
- Higher brain energy levels on ketogenic diets compared to high-carbohydrate diets
- Protection against the energy metabolism problems that typically plague APOE4 carriers
As researcher Kira Ivanich explained: "When we eat carbs, our brains convert the glucose into fuel for our brains, but those with the APOE4 gene—particularly females—struggle to convert the glucose into brain energy, and this can lead to cognitive decline down the road."
Beyond Alzheimer's: Comprehensive Health Benefits of Ketosis
Mitochondrial Renewal and Longevity
"Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God?" (1 Corinthians 6:19)
Caring for these temples extends to supporting the tiny powerhouses within our cells—the mitochondria. Research demonstrates that ketogenic diets profoundly improve mitochondrial function:
Increased Lifespan and Healthspan
A landmark 2017 study by Roberts and colleagues found that mice on ketogenic diets lived 13.6% longer with significantly increased skeletal muscle mitochondrial mass and enzyme activity in late life. The diet essentially turned back the clock on age-related mitochondrial decline.
Enhanced Mitochondrial Efficiency
A 2020 study published in the American Journal of Physiology followed 29 physically active adults through a 12-week exercise program. Those on ketogenic diets showed:
- Greater mitochondrial capacity and efficiency, particularly for fat oxidation
- Increased total ATP production (cellular energy)
- Improved ATP production per unit of oxygen consumed
- Reduced reactive oxygen species (damaging free radicals)
Researchers concluded: "The ketogenic diet improved metabolic health markers and resolved indicators of insulin resistance in conjunction with weight loss and exercise, implying that alteration of mitochondrial function is worthy of consideration as a mechanism through which ketogenic diets exert therapeutic benefits."
Mitohormesis: Stress That Strengthens
The ketogenic diet induces a phenomenon called "mitohormesis"—where moderate mitochondrial stress triggers protective adaptations including:
- Upregulation of endogenous antioxidant defenses
- Enhanced resistance to oxidative damage
- Improved mitochondrial quality control
- Increased production of protective proteins
As 2 Corinthians 12:10 reminds us: "For when I am weak, then I am strong." This principle applies even at the cellular level—strategic metabolic stress strengthens our mitochondria.
Metabolic Health and Insulin Sensitivity
Multiple studies demonstrate that ketogenic diets improve markers of metabolic health:
- Decreased fasting insulin and improved insulin sensitivity
- Reduced insulin resistance (HOMA-IR scores)
- Increased whole-body fat oxidation at rest
- Improved glucose regulation
- Reduction in visceral (abdominal) fat
- Decreased inflammation (lower C-reactive protein)
A 2024 study in Clinical Nutrition found that ketogenic diets, along with intermittent fasting and calorie restriction, improved mitochondrial function in immune cells while reducing systemic inflammation—particularly by decreasing lipopolysaccharide signaling from the gut.
Neuroprotection Beyond Alzheimer's
The ketogenic diet's neurological benefits extend far beyond Alzheimer's disease:
- Epilepsy: The most established use, reducing seizure frequency in drug-resistant cases
- Parkinson's Disease: Preliminary studies show improvements in motor symptoms and oxidative stress
- Traumatic Brain Injury: Enhanced neuroprotection and recovery
- Multiple Sclerosis: Reduced inflammation and improved energy metabolism
- General Cognitive Enhancement: Improved mental clarity, focus, and executive function
Liver Health and MASLD
Recent 2025 research published in Nutrition & Diabetes demonstrates that even a short 2-week ketogenic intervention can:
- Partially alleviate lipid deposition in the liver
- Restore mitochondrial dynamics balance
- Improve mitochondrial function in cases of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly called NAFLD)
Biblical Foundations for Fasting and Metabolic Flexibility
Throughout Scripture, we see patterns of fasting that naturally induce ketosis—a metabolic state our ancestors regularly experienced:
- Moses fasted for 40 days on Mount Sinai (Exodus 34:28)
- Elijah journeyed 40 days in the strength of miraculous provision (1 Kings 19:8)
- Jesus fasted 40 days in the wilderness before beginning His ministry (Matthew 4:2)
- Daniel practiced partial fasting, abstaining from choice foods (Daniel 10:3)
- The early church regularly incorporated fasting with prayer (Acts 13:2-3)
These periods of abstinence from regular food would have naturally elevated ketone production, potentially sharpening mental clarity and spiritual discernment. God designed our bodies to thrive—not merely survive—during these fasting periods.
As Isaiah 58:8 promises regarding proper fasting: "Then your light will break forth like the dawn, and your healing will quickly appear."
Supporting Ketogenic Metabolism with God's Pharmacy
While dietary changes form the foundation of ketogenic living, certain herbs and medicinal mushrooms can support and enhance the metabolic transition and cognitive benefits:
Turkey Tail Mushroom (Trametes versicolor)
Found in Forage Healing's HARMONY tincture, Turkey Tail has been extensively studied for its immune-supporting properties through polysaccharide-K (PSK) and polysaccharopeptide (PSP). Research published in Frontiers in Immunology demonstrates Turkey Tail's ability to modulate immune function and support gut health—crucial considerations since ketogenic diets significantly impact the microbiome.
A healthy gut microbiome is essential for optimal ketone metabolism and cognitive health. Studies show that the gut-brain axis plays a critical role in Alzheimer's disease progression, making Turkey Tail's prebiotic effects particularly valuable.
Artist's Conk/Birch Polypore (Ganoderma applanatum/Fomes fomentarius)
Featured in HARMONY and Birch Polypore Forage tinctures, these bracket fungi have been used medicinally for millennia. Ötzi the Iceman carried birch polypore 5,300 years ago, likely for its anti-inflammatory and antimicrobial properties.
Research indicates polypore mushrooms contain:
- Triterpenes with neuroprotective properties
- Beta-glucans that support immune function and reduce neuroinflammation
- Antioxidant compounds that protect against oxidative stress
The anti-inflammatory effects are particularly relevant for Alzheimer's disease, as chronic neuroinflammation is a key driver of cognitive decline.
Reishi Mushroom (Ganoderma lucidum)
Reishi, the "mushroom of immortality" in traditional Chinese medicine, offers profound support for both cognitive and metabolic health. Research published in journals including Bioorganic & Medicinal Chemistry and Evidence-Based Complementary and Alternative Medicine demonstrates:
- Neuroprotective effects through reduction of amyloid-beta plaques
- Enhanced nerve growth factor (NGF) production
- Improved mitochondrial function and reduced oxidative stress
- Modulation of neuroinflammation
- Support for insulin sensitivity and glucose metabolism
A 2017 study in International Journal of Molecular Sciences found that Reishi polysaccharides protected against cognitive impairment in animal models by reducing oxidative damage and supporting antioxidant enzyme activity.
Available in the Forage REST tincture.
Gotu Kola (Centella asiatica)
Gotu Kola has been revered in Ayurvedic medicine as a "brain tonic" for thousands of years. Modern research, including studies in Journal of Alzheimer's Disease and Evidence-Based Complementary and Alternative Medicine, validates this traditional wisdom:
- Enhances cognitive function and memory
- Protects neurons from oxidative stress and excitotoxicity
- Improves mitochondrial function in brain cells
- Reduces amyloid-beta accumulation
- Supports cerebral circulation and oxygenation
- Promotes neurite outgrowth and dendrite development
A 2016 systematic review found that Gotu Kola improved cognitive domains including memory, executive function, and processing speed. Its synergy with ketogenic metabolism makes it an ideal companion for cognitive health protocols.
Available in the Forage CLARITY tincture.
Practical Implementation: Making the Transition
Understanding the Ketogenic Approach
A well-formulated ketogenic diet typically consists of:
- 70-80% calories from healthy fats: avocados, olive oil, coconut oil, nuts, seeds, wild-caught fatty fish
- 15-20% from quality protein: grass-fed meat, pastured poultry and eggs, wild fish
- 5-10% from low-glycemic vegetables: leafy greens, cruciferous vegetables, non-starchy vegetables
The Importance of Clean, Organic Foods
"So whether you eat or drink or whatever you do, do it all for the glory of God." (1 Corinthians 10:31)
When pursuing ketogenic eating for health restoration, quality matters immensely:
Choose organic whenever possible to minimize exposure to pesticides, herbicides, and other toxins that burden the liver and disrupt hormonal balance. Prioritize Kosher, grass-fed and pastured animal products, which provide superior omega-3 to omega-6 ratios and lack the antibiotics and hormones found in conventional products. Select wild-caught fish over farmed to avoid contaminants and obtain optimal fatty acid profiles. Emphasize non-starchy organic vegetables to provide fiber, minerals, and phytonutrients that support the microbiome and reduce inflammation.
Key Nutrients to Monitor
While following a ketogenic diet, pay attention to:
- Sodium, potassium, and magnesium: Increased need during keto-adaptation
- Omega-3 fatty acids: Essential for brain health
- B vitamins: Support energy metabolism
- Vitamin D: Critical for cognitive and immune function
- Fiber: From non-starchy vegetables and supplements to support gut health
The Transition Period ("Keto-Adaptation")
The first 2-4 weeks of ketogenic eating involve adaptation as your body shifts metabolic gears:
- You may experience temporary fatigue, brain fog, or irritability ("keto flu")
- Adequate electrolytes and hydration minimize these symptoms
- After adaptation, most people report enhanced mental clarity and stable energy
Monitoring Ketone Levels
To ensure therapeutic ketone levels for cognitive benefit:
- Blood ketone meters provide the most accurate readings
- Aim for beta-hydroxybutyrate levels of 0.5-3.0 mmol/L
- Levels of 1.0-2.0 mmol/L are often optimal for cognitive benefits
- Consistency matters more than achieving very high levels
Combination Approaches
The research suggests that combining strategies may be most effective:
- Ketogenic diet + intermittent fasting: Enhances autophagy and mitochondrial renewal
- Ketogenic eating + regular exercise: Amplifies metabolic benefits
- Dietary ketosis + targeted supplementation: Herbs and mushrooms provide synergistic neuroprotection
- Nutritional ketosis + adequate sleep: Essential for clearance of brain metabolic waste products
The Spiritual Dimension of Metabolic Healing
Our approach to food and health is ultimately a spiritual matter. As we nourish our bodies in accordance with their God-given design, we honor the Creator:
"For you created my inmost being; you knit me together in my mother's womb." (Psalm 139:13)
Ketogenic eating, supported by herbs and mushrooms from God's pharmacy, represents a return to metabolic flexibility—a state our ancestors knew well through natural periods of feast and famine, seasonal eating patterns, and spiritual fasting.
The remarkable research on ketones and Alzheimer's disease reveals that even in the face of neurodegenerative disease, hope remains. The brain's preserved ability to utilize ketones demonstrates God's merciful provision—a backdoor fuel source that bypasses the glucose metabolism problems plaguing Alzheimer's patients.
Prayer and Fasting in New Light
Understanding ketosis also gives us fresh appreciation for the spiritual disciplines of fasting and prayer. When we fast:
- Our bodies naturally produce ketones
- Our brains function on an alternative, perhaps cleaner, fuel source
- We may experience enhanced mental clarity and spiritual sensitivity
- We participate in a practice that unites physical and spiritual renewal
As Jesus taught in Matthew 6:16-18, fasting should be done with joy and in secret—and now we understand that this practice also triggers profound metabolic benefits, demonstrating once again the integration of physical and spiritual health in God's design.
Hope for the Future: Emerging Research Directions
The scientific community continues to explore ketogenic interventions for cognitive health:
- Personalized ketogenic protocols based on genetic profiles (particularly APOE status)
- Combination therapies pairing ketogenic diets with other interventions
- Long-term studies examining sustained cognitive benefits over years
- Preventative applications for those at genetic risk
- Refined exogenous ketone formulations for easier implementation
- Microbiome-targeted strategies to enhance ketogenic adaptation
Conclusion: Healing Through Creation
"The earth is the LORD's, and everything in it, the world, and all who live in it." (Psalm 24:1)
God has provided everything we need for health and healing within His creation—from the metabolic flexibility encoded in our cells to the medicinal plants and fungi that grow in forests and fields. The emerging science on ketones and cognitive health reveals a truth that traditional healers have long understood: working with our bodies' innate design, rather than against it, unlocks remarkable healing potential.
The research is clear and compelling: ketogenic metabolism offers hope for those facing Alzheimer's disease and cognitive decline. Beta-hydroxybutyrate and other ketone bodies act as superior fuel for the brain, enhancing mitochondrial function, reducing inflammation, protecting synapses, and improving cognitive performance even in the face of disease.
As we combine this metabolic approach with the wisdom of herbal and mushroom medicine—the Turkey Tail, Reishi, Artist's Conk, Gotu Kola, and countless other gifts from God's pharmacy—we access a comprehensive strategy for cognitive health that honors both ancient wisdom and modern science.
"He makes grass grow for the cattle, and plants for people to cultivate—bringing forth food from the earth: wine that gladdens human hearts, oil to make their faces shine, and bread that sustains their hearts." (Psalm 104:14-15)
Let us remember that our Creator provided not just bread for sustenance, but a diverse array of plants, herbs, and fungi—each with specific healing properties. As we learn to work with our metabolism through ketogenic eating and support this journey with botanical allies, we participate in the restoration God desires for every aspect of our being—body, mind, and spirit.
May your journey toward cognitive health and metabolic wellness be blessed with wisdom, perseverance, and the profound healing that comes from aligning with your Creator's design.
