Harvard Genetics Professor David Sinclair has discovered a lifestyle approach that he believes has made his body function as though it is decades younger than his actual age.
At the core of his methodology are five key dietary practices that he meticulously avoids, alongside adopting a healthy diet, regular exercise, and specific supplements, all of which contribute to his claim of having a body that is “younger and healthier” than ever before.

Dr. Sinclair, a Professor of Genetics at Harvard Medical School, has experienced significant changes in his physical health and appearance over the years.
He attributes these changes to alterations in his diet and lifestyle, emphasizing the importance of exercise, eating habits, and the consumption of certain foods and supplements. His approach is based on scientific research, including the examination of his own blood biochemistry, which indicates improvements in health markers typically associated with youth.
The Role of Exercise
One of the pillars of Sinclair’s regimen is exercise, specifically the type that increases the body’s oxygen demand. He advises exercising to the point of breathlessness for about 10 minutes, three times a week, to stimulate the body’s stress response, which can lead to improved muscle build, better blood flow, and a slowed aging process.
Eating Less Frequently
The professor stresses the importance of eating less frequently, pointing out that constant eating accelerates the aging process. He practices time-restricted feeding, aiming to eat within a six-hour window each day. This approach is not only about what to eat but also when to eat, highlighting the benefits of fasting on the body’s defenses against aging and disease.
Plant Based Foods
Sinclair’s diet focuses on plant-based foods, particularly those he describes as “stress plants,” which are believed to activate the body’s cellular stress response, potentially leading to improved lifespan and fitness. He emphasizes the consumption of foods rich in plant polyphenols, like green tea, spinach, and olive oil, and follows a Mediterranean or Okinawan diet, rich in vegetables, fruits, and healthy fats.
Supplements
In terms of supplements, Sinclair mentions resveratrol, NMN (a form of vitamin B3), and metformin, though he does not endorse any specific brand or product. He highlights the importance of these supplements in maintaining levels of NAD, a critical molecule for life, and supporting the function of sirtuins, a family of proteins that play a key role in aging and longevity.
Dietary Exclusions
Dr. Sinclair has made significant dietary exclusions for longevity, notably cutting out sugar, bread, meat, dairy, and alcohol.
He points out the detrimental effects of high sugar intake, the benefits of reducing carbohydrate consumption, and the advantages of a plant-based diet over one that includes meat and dairy. While he acknowledges the enjoyment derived from certain foods and beverages, Sinclair advocates for moderation and choosing healthier alternatives to support a long and healthy life.
Overall, David Sinclair’s approach to achieving a younger and healthier body combines scientific research with practical lifestyle changes, emphasizing the importance of diet, exercise, and supplements in slowing the aging process and enhancing overall well-being.
5 Key Takeaways
Exercise Regularly: Engage in high-intensity exercise that leads to breathlessness for about 10 minutes, three times a week, to stimulate the body’s stress response and promote muscle growth, better blood flow, and slowed aging.
Practice Time-Restricted Feeding: Eat less frequently, preferably within a six-hour window each day, to enhance the body’s defense mechanisms against aging and support weight loss and longevity.
Focus on a Plant-Based Diet: Consume foods rich in plant polyphenols, such as green tea, spinach, and olive oil, and adhere to a Mediterranean or Okinawan diet, emphasizing the benefits of vegetables, fruits, and healthy fats.
Supplement Wisely: Include supplements like resveratrol, NMN (a form of vitamin B3), and metformin (with medical consultation) to support cellular health, maintain NAD levels, and activate longevity genes.
Eliminate Certain Foods: Avoid sugar, bread, meat, dairy, and alcohol to improve metabolic health markers, reduce inflammation, and minimize the risk of diseases associated with aging.
