Preventing Type 2 Diabetes: Practical Steps

Understanding Prediabetes

Prediabetes affects 1 in 3 adults, with fasting glucose levels between 100-125 mg/dL indicating increased risk. Without intervention, 70% of prediabetics develop type 2 diabetes. Early identification through routine screening allows for timely lifestyle interventions that can prevent or delay progression.

Dietary Strategies

Mediterranean and low-glycemic index diets show particular promise for diabetes prevention. Emphasizing whole foods, healthy fats, and fiber while minimizing processed carbohydrates helps stabilize blood sugar. Even modest weight loss (5-7% of body weight) can reduce diabetes risk by 58% in high-risk individuals.

Physical Activity Benefits

Both aerobic exercise and resistance training improve insulin sensitivity. Aim for 150 minutes weekly of moderate activity, plus 2-3 strength sessions. Simple strategies like walking after meals can significantly blunt postprandial glucose spikes.

Monitoring and Maintenance

Annual glucose testing helps track progress in high-risk individuals. Stress management and quality sleep also contribute to metabolic health. These lifestyle changes prove most effective when incorporated as permanent habits rather than temporary measures.

When Medication May Help

For some high-risk patients, metformin may be considered alongside lifestyle changes. Recent studies show GLP-1 receptor agonists can reduce progression risk by up to 80%, though lifestyle modification remains first-line for most patients.
