Dr. Kumar’s Take:
This long-term study gives us something very simple and powerful: just walking faster or being a little more active in your free time could lower your risk of dying from heart disease—especially if you have type 2 diabetes or prediabetes. The more physically active you are, the better your chances of living longer and healthier. If you’re managing diabetes, building in physical activity isn’t just good advice—it might be life-saving.
Key Takeaways:
✔ Men with diabetes or prediabetes who walked faster had a much lower risk of death from heart disease.
✔ Leisure-time physical activity also reduced risk—but not as strongly as walking pace.
✔ The benefits of physical activity were even greater in men with diabetes or impaired glucose tolerance compared to healthy men.
Actionable tip:
If you have diabetes or prediabetes, start by walking a little faster each day or adding simple physical activities like gardening or swimming to your weekly routine. Even modest increases in activity may help you live longer.
Brief Summary:
This 25-year observational study followed 6,408 British male civil servants. It compared men with normal blood sugar to those with type 2 diabetes or impaired glucose tolerance. The study found that men who walked faster or were more active during their free time were less likely to die from heart disease or other causes. The benefits of physical activity were especially strong in those with diabetes or impaired glucose tolerance.
Study Design:
The Whitehall study enrolled 18,403 men aged 40–64 between 1967–1969. This analysis included 6,408 men who had complete health and physical activity data. Researchers assessed walking pace and leisure activity through questionnaires. Participants were followed for 25 years, and death records were analyzed for cause-specific mortality such as coronary heart disease (CHD) and other cardiovascular disease (CVD).
Results:
- Men with diabetes or impaired glucose tolerance who walked slowly had more than 5 times the risk of dying from CHD than those who walked fast.
- Leisure activity was also protective, though the effect was smaller than walking pace.
- These patterns remained significant even after adjusting for other risk factors like smoking, cholesterol, and blood pressure.
- The protective effect of physical activity was stronger in men with diabetes/impaired glucose tolerance than in those with normal blood sugar.
Why Walking Speed Matters:
Walking faster is a simple but powerful sign of better heart and lung function. This study suggests that walking speed is not just a symptom of health but may directly influence longevity—especially in those at higher risk due to diabetes or prediabetes.

Frequently Asked Questions
How much walking is enough?
While the study didn’t measure exact step counts, simply walking at a brisker pace than usual showed benefits. Aim for walks where you feel slightly out of breath but can still talk.
Is this advice just for men?
This study looked only at men, but other research suggests women with diabetes benefit from physical activity too. More studies are needed, but staying active is good advice for everyone.
What if I have complications from diabetes?
If you have heart problems, foot ulcers, or other complications, talk with your doctor before starting any new exercise routine. But in most cases, regular physical activity is encouraged.
Do I need a gym membership?
Not at all. Walking, gardening, home chores, or dancing all count. What matters is doing something consistently.
Conclusion
For men with type 2 diabetes or impaired glucose tolerance, physical activity—especially walking at a faster pace—was strongly linked with a lower risk of death, particularly from heart disease. These findings suggest that simply moving more can make a big difference, especially for those managing blood sugar issues.
If you’re living with diabetes, get moving. It could save your life.
