What is prediabetes and can you reverse it?

Prediabetes affects 96 million American adults — and most don't know they have it.

Diagnostic numbers

• Fasting glucose: 100–125 mg/dL
• 2-hour post-meal glucose: 140–199 mg/dL
• HbA1c: 5.7%–6.4%

Any one of these triggers a prediabetes diagnosis.

What happens without intervention

• 70% will progress to type 2 diabetes within 10 years
• Cardiovascular risk is already elevated
• Kidney function may already be declining

What reverses it

### The Diabetes Prevention Program (DPP) results

• 7% weight loss + 150 min/week walking: 58% reduction in diabetes progression over 3 years
• Metformin: 31% reduction (less effective than lifestyle)
• Combined: maximum benefit

### The most powerful single interventions

1. **Lose 7% of body weight** (15 lbs for a 200-lb person)
2. **Walk 30 minutes/day** — even split into chunks
3. **Cut refined carbs and sugar** — keep total carbs under 130g/day
4. **Strength train twice weekly** — builds glucose-burning muscle
5. **Sleep 7+ hours** — non-negotiable
6. **Manage stress** — chronic cortisol matters

What to track

• Fasting glucose monthly
• HbA1c every 3–6 months
• Waist circumference
• Triglyceride/HDL ratio (under 2.0 is ideal)

The good news

Prediabetes is the most reversible point in the diabetes timeline. Many people return to normal glucose within 6 months of serious lifestyle changes. Acting now is far easier than managing diabetes later.
