📚 Introduction

In the pursuit of a longer, healthier life, there are various factors to consider, including aging, healthspan, and personalized diets. This blog post explores the fascinating world of continuous glucose monitors, the biology of aging, the Dog Aging Project, the potential of rapamycin, and the importance of nutrition and exercise. It also delves into the influence of NAD levels, the effectiveness of treatments for aging, and the uncertain reality of resveratrol as an anti-aging therapy.

🔍 Wisdom Unpacked

Delving deeper into the key ideas.

1. CGMs and personalized diet apps can enhance health and well-being.

Continuous glucose monitors (CGMs) provide valuable insights into glucose levels, helping with blood sugar stability, chronic conditions, mood, energy levels, and weight management. The levels app interprets glucose data and offers a personalized diet based on individual responses to food. Healthspan, a concept of good health, is becoming popular but is difficult to quantify. Element, a sugar-free electrolyte drink mix, can help with electrolyte needs, hormone imbalances, and hunger cramps. Personalized diet apps like levels can help understand how different foods affect you and develop a personalized diet.

2. Understanding and addressing aging biology can increase lifespan and healthspan.

The biology of aging is a complex and fascinating field that is significantly underfunded compared to cancer research. However, with the right investment, this field has the potential to increase lifespan and maximize healthspan by addressing multiple diseases simultaneously. The field is actively exploring solutions to address the infrastructure and therapist requirements. A dedicated marketing plan and investment in clinical trials are crucial to highlight the significance of this research and its biology. Scientists can also fall for hype and be misled by the way data is presented, so it's important to read the paper and not just the abstract. There is a positive publication bias in science, which can lead to a focus on shiny new objects and a lack of replication. To address this, it is important to develop the best model possible for what is being studied, and then identify the weaknesses and design experiments to break the model. This approach allows for progress and a closer understanding of reality. Despite the noise and hype in the field, there is a lot of reason to be optimistic about the biology and potential therapeutics.

3. Dog aging study explores interventions to extend lifespan, with potential insights for humans.

The Dog Aging Project is a longitudinal study of aging in companion dogs, aiming to understand the factors that influence aging and develop diseases. The study consists of a longitudinal study and a clinical trial, with the latter testing a drug called rapamycin to slow or reverse aging in companion dogs. The study's goal is to help dogs live longer, healthier lives. When considering interventions to extend lifespan in dogs, it's beneficial to start with interventions that have been shown to extend lifespan in mice. These interventions include caloric restriction, pharmacological interventions like intermittent fasting, and small molecules like rapamycin, carbose, 17 alpha estradiol, NDGA, metformin, and NAD precursors. However, it's crucial to consider the safety and potential harm to the dogs. While intermittent fasting for increasing lifespan is still largely unknown territory, a study found that dogs fed once a day had fewer disease diagnoses compared to those fed more than once a day. However, more research is needed to understand the direct connection between once a day feeding and health outcomes.

4. Rapamycin, a drug for transplant rejection, shows promise in aging reversal.

Rapamycin, a drug commonly used to prevent organ transplant rejection, has shown significant benefits for aging in mice studies. It can reverse functional declines in the immune system, heart, and oral cavity, and may have similar effects on other tissues. It is believed to reduce chronic inflammation, allowing stem cells to function properly. However, continuous use of rapamycin may not be preferred, and intermittent cycles are being explored. Rapamycin has also been shown to improve cognitive function in mice and maintain muscle function in old animals. It is being explored for rejuvenating ovarian function in women with premature ovarian failure and for the treatment of periodontal disease. However, the optimal dosage and frequency of rapamycin are still unknown, and the potential side effects associated with long-term use need to be considered.

5. Influence aging with interventions, nutrition, exercise, and sleep.

The aging process can be influenced by various interventions, including caloric restriction and rapamycin, which have been shown to extend lifespan and healthspan in mammals. Nutrition, particularly a low simple carbohydrate diet, and resistance exercise are also crucial for maintaining health and potentially extending lifespan. Sleep is also important, although it can be challenging to control. Physicians need to change their mindset and consider the risk of doing nothing to maintain health, as potential interventions like rapamycin may increase healthy lifespan by 10%. However, there is a fear of liability and defensive medicine, which can be addressed by educating medical students about the modifiability of aging biology.

6. NAD boosters, natural products, and pharmacological autophagy boosters can extend lifespan.

The aging process is influenced by various factors, including the decline of NAD levels, which can negatively impact metabolism. Boosting NAD levels can have beneficial effects on metabolism, and NAD precursors, such as NAD and NADH, play a significant role in central metabolism. Alpha-ketoglutarate, oleithin a, and spermidine are natural products that can extend lifespan in mice, with spermidine working by enhancing autophagy. Depronil, a substance with cognitive benefits and effects on libido, has been shown to have lifespan-extending effects in rodents and dogs. However, the research on it has stalled. NAD precursors, when taken intravenously, can boost NAD levels in cells, but there are controversies and open questions surrounding their use.

7. Effective aging treatments consider individual conditions and potential risks.

The effectiveness of treatments for aging is influenced by the condition and comorbidities of the group being treated. For instance, metformin may not be beneficial for individuals with a healthy lifestyle. Similarly, NAD, often discussed in relation to aging, can have uncomfortable side effects. It's crucial to consider the potential benefits and risks of any treatment, including the risk-reward ratio and the consequences of doing nothing. Two strategies are being taken to target aging: the Metformin trial, which focuses on the frequency of age-related disease diagnoses, and the second approach, which considers age-related indications with a shorter time frame, such as functional measures of aging like immune function.

8. Resveratrol, while having biological activities, is not a reliable anti-aging therapy.

Resveratrol, a compound found in red wine, gained popularity for its potential health benefits, including anti-aging effects. However, its effectiveness as an anti-aging therapy is still uncertain. Resveratrol was believed to activate sirtuins, a family of proteins that decline with age, but studies have shown that it does not activate sirtuins in the same way as previously thought. While resveratrol has biological activities, it is not a reliable anti-aging therapy. It's important to approach any intervention, including resveratrol, with a critical mindset and consider its potential side effects.

💡 Actionable Wisdom

Transformative tips to apply and remember.

To improve your health and potentially extend your lifespan, consider using a continuous glucose monitor to gain insights into your glucose levels and make informed dietary choices. Incorporate regular exercise, prioritize a low simple carbohydrate diet, and ensure adequate sleep. Stay informed about the latest research on aging and potential interventions, but approach them with a critical mindset and consult with healthcare professionals before making any significant changes. Remember, personalized approaches based on individual responses to food and lifestyle factors are key to optimizing health and well-being.
