Reversed pre-diabetes diagnosis at 58 through lifestyle changes, avoiding medication for 4 years

I was told I was pre-diabetic at 58. I'm a retired school counselor, not a doctor. Rather than go straight to medication, I worked with my physician to try lifestyle interventions first — and it worked. I share what the research says about chronic disease prevention and senior health, verified against NIH and AHA data. This is general information only. Always work with your physician before changing your treatment plan — especially for chronic conditions.

As a retired school counselor, I've always believed that prevention is key when it comes to chronic diseases. Now, at 70, I'm living proof that lifestyle interventions can work miracles. According to the CDC, nearly 90% of adults with diabetes have prediabetes, and more than 80% of adults with heart disease don't have symptoms (CDC, 2024). That's why I'm excited to share the latest research on Zone 2 Cardio, a low-intensity training that's gaining traction among doctors.

What the Latest Research Shows

Zone 2 Cardio is a type of exercise that involves working at a moderate intensity for an extended period. Recent studies have shown that this type of training can be just as effective as high-intensity interval training (HIIT) for improving cardiovascular health (Harvard T.H. Chan School of Public Health, 2025). In fact, a study published in the Journal of the American College of Cardiology found that Zone 2 Cardio can help reduce inflammation and improve insulin sensitivity in individuals with type 2 diabetes (NIH, 2024).

Many of us believe that high-intensity exercise is the only way to get fit and healthy. However, the data suggests that low-intensity training can be just as effective, and even more sustainable, for many people (World Health Organization, 2025). According to the American Heart Association, exercising at moderate intensity for at least 150 minutes per week can help reduce the risk of heart disease and stroke (AHA, 2024).
