A recent study from Harvard suggests that humans might be nearing the limits of their life expectancy. However, many people are still eager to explore ways to extend their lives. A poll indicated that 81% of people are "somewhat or very willing" to invest money for a longer life, although many feel uncertain about where to begin.
Dr. Sajad Zalzala, a physician and co-founder of AgelessRx in Detroit, Michigan, is passionate about helping individuals lead not only longer lives but healthier ones as well. His background in functional medicine allows him to focus on the underlying causes of health issues, which has driven him to address the challenges of aging.
In 2019, Zalzala launched AgelessRx to tackle what he describes as "the puzzle of aging." He has shared insights on aging and the essential elements of living a longer, healthier life during discussions with various media outlets.
Understanding the Aging Process
Aging manifests differently in each individual, yet researchers have found common characteristics associated with the aging process. Dr. Zalzala discussed some of these aging markers:
- Genomic Instability: Damaged DNA can lead to illnesses like cancer and reduce the body’s healing capacity.
- Telomere Attrition: Shorter telomeres are linked to visible aging symptoms, like wrinkles, and slower cell regeneration.
- Epigenetic Alterations: Changes in gene function due to environmental factors can speed up aging and lead to metabolic issues.
- Loss of Proteostasis: Misfolded proteins are involved in age-related diseases such as Alzheimer’s.
- Mitochondrial Dysfunction: As energy production declines, people may experience fatigue and muscle weakness.
- Deregulated Nutrient Sensing: Problems with metabolism regulation contribute to aging.
- Cellular Senescence: Aging cells can stop dividing, leading to thinner skin and age spots.
- Stem Cell Exhaustion: Fewer stem cells can result in changes like gray hair and slower recovery.
- Altered Intercellular Communication: Poor cell communication impacts tissue health and the immune system.
- Disabled Macroautophagy: This refers to a slowdown in processes that provide cells with energy.
- Chronic Inflammation: Increased inflammation in older individuals is tied to many age-related diseases.
- Dysbiosis: An imbalance in gut microorganisms can negatively affect health.
Dr. Zalzala emphasizes that many of these aging traits can be managed with positive lifestyle changes. He believes that factors like diet, exercise, and overall health can significantly influence the aging process.
Key Aspects of Healthy Living
Dr. Zalzala outlines several healthy habits he follows under five main categories:
-
Healthy Eating: He follows a "Paleo-like" diet, focusing on whole foods such as vegetables, low-glycemic fruits, and lean proteins. Zalzala generally avoids highly processed foods and sugars, as well as high-glycemic fruits like bananas and grapes, preferring berries and cherries.
-
Staying Active: While he admits to not being a big exercise enthusiast, Dr. Zalzala values physical activity in the fight against aging. He uses a walking desk and practices martial arts with his son. He also engages in brief cardio and weight training sessions.
-
Careful Medication Use: Dr. Zalzala believes in tailoring medications to individual health objectives. He regularly takes metformin, a drug commonly used for diabetes, which some studies suggest may also promote longevity. He has also started taking rapamycin and occasionally uses medicines to help manage blood sugar and cholesterol.
-
Supplementing Wisely: He is a proponent of using supplements to enhance health, including vitamin D, DHEA, and Coenzyme Q10. He believes they can offer various benefits, depending on individual health needs.
- Improving Sleep Quality: Lastly, Dr. Zalzala stresses the importance of good sleep hygiene. He underscores that poor sleep can disrupt metabolism and hormonal balance, making it critical to monitor sleep patterns and address any disorders with a healthcare provider.
As people continue to search for ways to live longer and healthier lives, lifestyle choices play a significant role in how we age. Dr. Zalzala’s insights provide a practical roadmap for those looking to enhance their well-being as they grow older.
