Pre-diabetes Action Plan

Yes. The DPP showed that lifestyle changes reduced the risk of developing type 2 diabetes by 58% — more effective than metformin alone. Key interventions: losing 5–7% of body weight, exercising 150 min/week and improving diet. Many people return to normal blood sugar within 1–3 years of consistent lifestyle changes.

Many people see measurable improvements in blood sugar within 8–12 weeks of consistent lifestyle changes. Full reversal (HbA1c below 5.7%) can take 3–12 months. Get your HbA1c tested every 3–6 months to track progress.

The most effective approach: significantly reduce refined carbohydrates, sugar and sweetened drinks; increase non-starchy vegetables, legumes and whole grains; choose low glycemic index foods; eat regular portion-controlled meals. The Mediterranean diet and low-GI diet both have strong evidence.

The DPP recommends at least 150 minutes of moderate-intensity aerobic exercise per week — 30 minutes of brisk walking, 5 days a week. Adding resistance training 2–3 days per week provides additional benefit. Even a 10-minute walk after each meal significantly reduces post-meal blood sugar.

For most people, lifestyle changes are the first-line treatment and more effective than medication. Some doctors prescribe metformin for high-risk cases. Medication does not replace lifestyle changes. Discuss with your doctor whether medication is right for you.
