In the quest for longevity, health hacking often presents a bewildering array of trends, tips, and opinions that can seem contradictory. From taking cold plunges to indulging in sauna sessions and striving for 10,000 daily steps, the advice can overwhelm anyone trying to navigate the best practices. Take Bryan Johnson, for example; the head of the Don’t Die regime, he consumes supplements like candy—though he avoids candy itself.
When it comes to diet, the stakes are equally high. The connection between what we eat and how long we live can be murky. Some advocate for high meat consumption, while others strongly oppose it. Walter Willett, a nutrition researcher at Harvard T.H. Chan School of Public Health, famously remarked that “meat is like radiation,” emphasizing that we don’t yet know the safe levels of consumption.
Walter Longo, the director of the Longevity Institute at the University of Southern California, presents a clearer path for those aiming to extend their lives. His website explicitly states, “Eat mostly vegan.” He recommends a low protein intake and suggests adhering to a fasting schedule, where all meals occur between 8 a.m. and 8 p.m.
This raises the question: how can we optimize our diets for better health and longevity?
Dr. Frank Hu, a Harvard professor specializing in nutrition and epidemiology, emphasizes that there is no universal diet suitable for everyone. However, various dietary patterns can effectively prevent chronic diseases and enhance longevity.
Keep It Real
The primary guideline for anyone looking to live a long, healthy life is to steer clear of ultraprocessed foods. Items such as packaged snacks, cookies, fast-food burgers, and soda are detrimental to your health, despite their immediate appeal.
“Ultraprocessed foods are pervasive and contribute to our daily diets; they are often laden with sugar, sodium, and unhealthy fats,” notes Dr. Hu.

The renowned Mediterranean Diet is often hailed as one of the most effective for preventing chronic illness and supporting heart health. It emphasizes reducing dairy intake while increasing fish and omega-3-rich foods, as detailed in this comprehensive guide.
Another essential aspect of the Mediterranean approach is being mindful of the types of fats and carbohydrates consumed rather than eliminating them entirely. Incorporating extra virgin olive oil is a hallmark of this diet. “It not only helps lower cholesterol but may also protect against chronic conditions like dementia and Alzheimer’s,” adds Hu.
Red meat does not need to be completely off-limits. If you enjoy a steak from time to time, opt for lean cuts like strip or flank, which provide vital nutrients such as zinc, heme iron, and B vitamins.
Go Blue
Regions known as Blue Zones—like Okinawa and Sardinia—are celebrated for the longevity of their residents. The people in these areas often engage in regular physical activity and maintain rich social connections, enabling them to live well past the age of 80. Their diets typically consist of a striking 95-5 ratio, with only 5 percent of their meals containing animal protein, while 95 percent are plant-based. In Loma Linda, California, home to the world’s highest population of centenarians, a vegetarian lifestyle predominates, and both alcohol and caffeine are minimized.
In conclusion, the path to a long and healthy life lies in mindful eating and lifestyle choices that prioritize well-being over fleeting indulgences. By embracing whole foods, reducing ultraprocessed items, and drawing inspiration from dietary patterns found in Blue Zones, individuals can enhance their chances of longevity.
