Marshall Medical Group • May 19, 2025

Here are 10 evidence-based ways to add healthy decades to your life—focusing not just on longevity, but also on quality of life:

1. Eat a Whole-Food, Plant-Forward Diet

  • Prioritize fruits, vegetables, whole grains, legumes, nuts, and seeds.


  • Limit processed foods, red meats, and added sugars.


  • Diets like the Mediterranean or Blue Zones diet are linked to long, healthy lives.

2. Exercise Regularly

  • Aim for 150–300 minutes of moderate aerobic activity or 75–150 minutes of vigorous activity per week.


  • Include strength training at least twice weekly.



  • Movement helps reduce risk of heart disease, diabetes, cancer, and dementia.

3. Get Quality Sleep

  • Strive for 7–9 hours of restorative sleep per night.



  • Poor sleep is linked to obesity, heart disease, and shorter lifespan.

4. Manage Stress

  • Chronic stress harms heart, immune function, and mental health.


  • Practices like meditation, deep breathing, yoga, and time in nature are effective.


5. Maintain Strong Social Connections

  • Loneliness increases mortality risk as much as smoking or obesity.



  • Prioritize relationships with friends, family, and community.

6. Avoid Tobacco and Excess Alcohol Intake. 

  • Smoking is a leading cause of preventable death.


  • If you drink, do so in moderation: up to 1 drink/day for women, 2 for men.

7. Stay Mentally Active

  • Engage in lifelong learning, reading, puzzles, or creative activities.



  • Cognitive stimulation helps protect against dementia and cognitive decline.

8. Maintain a Healthy Weight

  • Obesity increases risk for heart disease, cancer, and diabetes.



  • Focus on sustainable habits, not crash diets.

9. Get Regular Health Screenings
