Give your Diet a Japanese Boost
The science is very consistent when it comes to diets that improve longevity and prevent disease, the Mediterranean diet, and the Japanese/Okinawan dietTrusted Source are the best. While they might seem worlds apart in terms of culture and geography, both emphasize similar dietary patterns. They are heavy on fish as a source of protein, which is rich in brain-boosting and heart-healthy fatsTrusted Source. They also include plenty of whole vegetables (fresh or fermented) and limit heavily processed foods and sugar.
As we approach the new year, know that no one quick fix diet” will be impactful. When we think about longevity, we must consider dietary patterns and changes that will provide long-lasting impact and, most importantly, are sustainable!” said Alyssa Kwan, MS, RD, Clinical Dietitian in Cardiology, Stanford Medicine.
If you want to start changing your diet to better align with these practices but aren’t sure where to start, here are some simple tips.
“Focus on one component at a time and make sure it’s something that fits within your personal, religious, and/or cultural preferences. For example, if you enjoy lentils, use them instead of white rice in veggie bowls. But if you dislike fish, then focus on other sources of protein,” said Kristin Kirkpatrick, MS, RD, a nutritionist at the Cleveland Clinic, and co-author of Regenerative Health.

Shed those Excess Pounds
Obesity is linked to numerous chronic illnessesTrusted Source, including cardiovascular disease and diabetes, and yes, even a shorter lifespan. For many adult Americans, shedding a few excess pounds can be tremendously beneficial to longevity and overall health.
But rather than just trying to lose weight, learn about the ideal body weight for your age, sex, and height. Losing even 5% of your body weightTrusted Source can significantly impact everything from blood sugar to blood pressure.
“Maintaining a healthy weight across life stages is critical for healthy aging and for improving both lifespan and healthspan,” said Frank B. Hu, MD, PhD, professor and chair of the Department of Nutrition, Harvard T.H. Chan School of Public Health.
“Clinical trials have shown that weight loss achieved through lifestyle changes, medications such as GLP-1 agonists, or weight loss surgeries is associated with a reduced risk of chronic diseases, including diabetes, cardiovascular disease (CVD), and certain cancers, and premature death,” said Hu.
Cut Down on Sitting
There’s a good chance that you are sitting far more than is good for your health. That’s likely no fault of your own you sit when you use a computer, watch TV, or meet friends at a coffee shop. But as our lives have become more sedentary, science has homed in on the negative effects that can have on longevity and disease risk.
“Sedentary behavior, such as prolonged TV watching, has been associated with an increased risk of chronic diseases, including diabetes, cardiovascular disease (CVD), and premature death. This heightened risk is primarily attributed to increased obesity and the displacement of physical activity,” said Hu.
Even if you exercise regularly, sedentary behavior has serious health risks associated with it. So don’t just think about trying to offset lazy days with a hard gym session. Think about ways to increase physical activity throughout the day, even if it just means taking a walk around your house or office, even if you are still exercising regularly.
Exercise: The More, the Better
Regular exercise is one of the best things you can do for your health. And it’s not just about your body either. The benefits extend to brain health and cognitionTrusted Source, too.
New research published in December 2024 found that among older adults, cardiorespiratory fitness was an excellent indicator of brain health across multiple domains of cognition, including memory.
Finding ways to increase physical activity and cut down on sedentary time in a manner that is enjoyable is key to making the habit sustainable. As a starting point, the CDC recommendsTrusted Source that adults get a minimum of 150 minutes per week of moderate-intensity physical activity.
“The two things in older adults that we see as a result of aging that lead to decreases in their quality of life are changes in cognition, and functionality, staying up on your feet. Exercise is far and away the thing that impacts both of them,” Katherine T. Ward, MD, clinical section chief of geriatrics at Stanford Medicine, told Healthline.
Boyce adds that establishing habits that can reduce sedentary behaviors and increase activity at the same time is a great place to start. You can also build physical activity into your everyday life. For instance, get off the train one stop early and walk or bundle behaviors like only watching TV while you’re exercising, she said.
Stop smoking
Yes, you’ve heard it before, but the science is as firm as ever: stop smoking, and you will live longer. Period.
In a study led by Frank Hu and published in 2018Trusted Source, researchers found that “never” smoking was one of five key factors for prolonging life expectancy. The others were:
- maintaining a healthy weight
- regular physical activity
- healthy diet
- only consuming a moderate amount of alcohol
Cigarette smoking is associated with roughly one of every five deaths in the United States each year, amounting to more than 480,000 deaths annually.
Why is smoking so deadly? It is linked to everything from cancer and heart disease to diabetes and COPD. Stopping smoking not only lowers your risk of all these diseases but can addTrusted Source as much as ten years to life expectancy.
