Prediabetes Reversal: Evidence-Based Strategies

Prediabetes reversal — bringing blood sugar back into the normal range — is achievable for many adults, and the strongest evidence supports a combination of modest weight loss, regular physical activity, better sleep and, for some higher-risk patients, medication. In the landmark Diabetes Prevention Program, a structured lifestyle program reduced progression to type 2 diabetes by 58% over about three years. The earlier prediabetes is identified and addressed, the better the odds.

What Is Prediabetes?

Prediabetes means blood sugar is higher than normal but not yet in the diabetes range. It is diagnosed by any of these tests:

• Fasting plasma glucose: 100–125 mg/dL
• Hemoglobin A1c (HbA1c): 5.7%–6.4%
• Two-hour oral glucose tolerance test: 140–199 mg/dL

According to the CDC, roughly one in three American adults has prediabetes, and most do not know it. That is a missed opportunity, because prediabetes is not just a "pre" condition. Insulin resistance — the underlying problem — is linked to fatty liver disease, high triglycerides, high blood pressure and cardiovascular risk, often years before glucose reaches the diabetes range.

Why Prediabetes Happens

The core issue is insulin resistance. Muscle, liver and fat cells respond less efficiently to insulin, so the pancreas produces more to keep glucose normal. For a time, it succeeds. Eventually, insulin output can't keep up and blood sugar begins to climb.

Common contributors include:

• Excess visceral (abdominal) fat and fat stored in the liver
• Physical inactivity and loss of muscle mass
• Poor or short sleep and untreated sleep apnea
• Chronic stress and elevated cortisol
• Certain medications, such as steroids
• Genetics and family history

Evidence-Based Strategies for Prediabetes Reversal

1. Modest, sustained weight loss

The Diabetes Prevention Program targeted a 7% reduction in body weight. For someone weighing 220 pounds, that is about 15 pounds. Losing liver and visceral fat improves insulin sensitivity disproportionately, which is why modest weight loss works so well.

2. Regular physical activity — both kinds

The DPP target was about 150 minutes per week of moderate activity, such as brisk walking. I encourage patients to combine:

• Aerobic training, including steady, conversational-pace work like the approach described in Zone 2 Cardio: The Longevity Exercise Protocol
• Resistance training two to three times per week, because muscle is the body's largest glucose "sink"
• Short walks after meals, which can blunt post-meal glucose spikes

3. A sustainable eating pattern

No single diet is required. What matters most is a pattern you can maintain: fewer refined carbohydrates and sugary drinks, more fiber, vegetables, legumes and minimally processed foods, adequate protein, and an overall calorie level that supports gradual weight loss.

4. Sleep and stress

Even a few nights of short sleep measurably worsen insulin sensitivity. Screening for sleep apnea is especially important in people with prediabetes, snoring or daytime fatigue.

5. Limit alcohol and review medications

Alcohol adds calories and can worsen fatty liver and triglycerides. Some medications raise glucose; a physician review can identify alternatives when appropriate.

What "Reversal" Really Means

I use the word reversal carefully. It means your glucose and A1c have returned to the normal range — not that the underlying tendency has disappeared. Insulin resistance can return if weight, activity or sleep slip back to old patterns, and genetics still matter. In long-term follow-up of the Diabetes Prevention Program, participants who returned to normal glucose regulation, even temporarily, had a lower subsequent risk of developing diabetes than those who did not. That is a strong reason to act early and to keep checking labs once or twice a year after you reach your goals, rather than treating a single normal result as the finish line.

When Medication Has a Role

Lifestyle change is first-line. Medication is considered for patients at higher risk or those who have not improved despite real effort.

• Metformin reduced diabetes incidence by 31% in the Diabetes Prevention Program — less than the lifestyle program, but meaningful, especially in younger adults with higher BMI.
• GLP-1–based medications such as semaglutide and tirzepatide are FDA-approved for chronic weight management in adults with obesity, or overweight with weight-related conditions. They are not approved specifically for prediabetes, but when obesity is present they can produce substantial weight loss and improvements in glucose. I discuss them further in GLP-1 Medications and Longevity: A Physician Perspective.

Medications work best alongside — not instead of — the foundations above, including resistance training to protect muscle during weight loss.

Labs Worth Tracking

A standard glucose or A1c result is a start, but a fuller picture helps guide treatment and track progress:

• Fasting glucose and HbA1c
• Fasting insulin (to estimate insulin resistance)
• Lipid panel, including triglycerides and HDL, and often apolipoprotein B
• Liver enzymes, as a clue to fatty liver
• Kidney function and urine albumin
• Blood pressure and waist circumference

How We Approach Prediabetes Reversal at Laeeq M.D.

At Laeeq M.D., prediabetes care is rooted in internal medicine: identifying the drivers specific to you, setting realistic targets, and rechecking labs to confirm progress. Longer visits make room for the conversations about sleep, training, nutrition and stress that a rushed appointment rarely allows. I serve patients from our office in Reston, VA, and virtually across several states.
