Research Methods
8-Week Program Details
The study implemented a lifestyle intervention delivered through a secure digital platform. This program was built around four main components:
Diet Protocol
Participants followed a plant-focused diet that included nutrient-rich animal proteins. Daily requirements were:
- 2 cups of dark leafy greens
- 2 cups of cruciferous vegetables
- 3 cups of colorful vegetables
- 6 ounces of grass-fed protein
Additionally, participants adhered to a time-restricted eating schedule, consuming all meals between 7 AM and 7 PM.
Exercise Requirements
Participants committed to 30 minutes of exercise, performed at 60-80% intensity, five days a week.
Stress Management
The program incorporated breathing exercises based on Dr. Herbert Benson's "Steps to Elicit the Relaxation Response." These exercises were practiced twice daily.
Sleep Optimization
Participants aimed for at least 7 hours of sleep each night to support overall health.
Study Participants
The research team carefully selected 43 healthy adult males who met the following criteria:
| Criterion | Requirement |
|---|---|
| Age Range | 50-72 years |
| Health Status | No history of recent or chronic disease |
| Location | Resided in the Portland, OR area |
| Commitment | Agreed to follow the study protocol |
The selected age range captured a period when age-related health changes are more likely to emerge. By focusing solely on male participants, the study avoided potential variability caused by hormonal differences [3].
Testing Methods
Advanced DNA methylation testing formed the backbone of the research:
Primary Testing Method
The study relied on Illumina Infinium methylation assays, capable of analyzing methylation at up to 850,000 sites [4]. This method was chosen for its broad coverage, efficiency, and cost-effectiveness.
Technical Process
- Bisulfite treatment was used to convert unmethylated cytosine into uracil, while methylated cytosines remained unchanged.
- By comparing treated and untreated samples, researchers identified methylation patterns.
Participant adherence to the program averaged 81.7%, with individual compliance ranging from 71.2% to 97.2% [5]. Weekly nutritional coaching in the first month, followed by bi-weekly sessions, played a key role in maintaining this high level of compliance [5].
These methods provided a solid foundation for analyzing how lifestyle choices influence DNA methylation patterns.
Aging: Clinical Trial on Potential reversal of Epigenetic Age using a Diet and Lifestyle
Lifestyle Factors Affecting DNA
Let’s dive into how specific lifestyle choices can directly influence DNA methylation and, in turn, impact biological aging.
Diet and Methylation
What you eat can play a significant role in shaping gene expression through DNA methylation. Research has shown that targeted dietary changes, particularly those rich in methyl donors, can reduce biological age by anywhere from 1.2 to 11 years in some individuals [6][7].
Here are some key foods and their effects on methylation:
| Nutrient Source | How It Supports Methylation |
|---|---|
| Dark Leafy Greens | Packed with folate, essential for methylation cycles |
| Cruciferous Vegetables | Provide methyl donors and natural anti-inflammatory compounds |
| Grass-Fed Protein | Rich in B vitamins, critical for methylation processes |
| Beets and Whole Grains | High in betaine, which supports methylation pathways |
| Eggs and Chickpeas | Excellent sources of choline, crucial for optimal methylation |
Exercise Effects
Physical activity doesn’t just boost your fitness - it also impacts your DNA. Studies reveal that endurance athletes exhibit significantly higher VO2 peak levels (67.0 ± 7.2 ml/min/kg compared to 36.2 ± 4.4 ml/min/kg in non-athletes), a marker of cardiovascular fitness. Strength training, on the other hand, has been linked to over 57,000 changes in DNA methylation [8][9]. These changes can influence everything from metabolism to muscle repair.
Stress and Sleep
Both stress and sleep quality are tightly connected to DNA methylation. Poor sleep, for instance, has been shown to result in widespread hypomethylation, with 78% of the affected DNA positions showing reduced methylation levels [10]. Additionally, a one-point increase on the sleep quality index was associated with a 15% rise in the risk of metabolic syndrome [11]. Stress management and restful sleep are particularly important for genes tied to brain health, such as those regulating neuroplasticity and neurodegeneration [10].
Taken together, these lifestyle factors highlight the powerful role of everyday habits in potentially slowing or even reversing biological aging.

Age Reversal Process
DNA Changes
In just eight weeks, the study revealed notable shifts in DNA methylation. Participants in the intervention group showed a reduction in biological age, becoming 3.23 years younger compared to the control group, which aged by 1.27 years during the same timeframe [3]. This treatment actively restored CpG methylation patterns typically seen in younger individuals [3]. These molecular adjustments laid the groundwork for improved cellular function.
Cell Health
The program brought measurable improvements in cellular health, reflected in several key biomarkers:
| Biomarker | Change |
|---|---|
| Triglycerides | 25% decrease (p=0.009) |
| 5-MTHF | 15% increase (p=0.004) |
| Program Adherence | 81.7% average (range: 71.2–97.2%) |
These findings, observed in otherwise healthy individuals, suggest the intervention targets core aging mechanisms rather than merely addressing aging linked to diseases.
Energy Production
Beyond structural improvements, better cell health translated into enhanced metabolic performance, particularly in energy production. NAD+ emerged as a critical player, with several striking observations:
- NAD-treated cells experienced an eightfold increase in NAD/NADH levels within 24 hours [12].
- DNA methylation in specific promoter regions dropped by 44% at 48 hours and 60% at 72 hours [12].
- Practices like regular exercise and calorie restriction also boosted NAD+ levels in mammalian cells [13].
"What is extremely exciting is that food and lifestyle practices, including specific nutrients and food compounds known to selectively alter DNA methylation, are able to have such an impact on those DNA methylation patterns we know predict aging and age-related disease." – Dr. Fitzgerald [2]
The treatment group showed an average reduction of 1.96 years in biological age from baseline (p=0.066) [3].

FAQs
What is DNA methylation, and how does reversing it impact aging?
DNA methylation is a natural mechanism that plays a key role in regulating gene activity and keeping our genome stable. As we age, these methylation patterns shift - generally decreasing overall but increasing in certain regions. These changes can interfere with normal gene function, potentially leading to issues like cancer or neurodegenerative disorders.
Reversing these shifts matters because it could help restore proper gene activity and enhance how cells function. Exciting new studies reveal that specific lifestyle changes can reverse DNA methylation patterns in as little as eight weeks. This not only suggests a reduction in biological age but also a potential decrease in the risk of age-related illnesses. It's a powerful reminder of how much impact our daily habits can have on longevity and health.
What lifestyle changes helped reverse biological aging in the study?
The study revealed that implementing specific lifestyle adjustments significantly reduced biological age. Over the course of an 8-week program, participants adhered to a health-oriented diet, maintained consistent physical activity, practiced stress-reducing methods such as mindfulness, and benefited from nutritional coaching. Together, these efforts resulted in an average reduction of 4.6 years in participants' biological age.
This research underscores how embracing a balanced lifestyle can profoundly influence health and extend longevity.
What are the potential risks or challenges of the lifestyle changes used in the study?
While the study highlights encouraging results in reversing DNA methylation and lowering biological age, there are some risks and challenges worth noting. How individuals respond to lifestyle changes can differ significantly due to factors like genetics, mental health, and environmental influences. This means the benefits observed may not be universal.
Another consideration is the study’s relatively short eight-week duration, which might not capture the long-term impact of these interventions. There’s also the chance that participants could slip back into old habits after the program ends, potentially diminishing or even canceling out the benefits over time. To truly understand how effective and sustainable these changes are, further research is essential.
