Can You Reverse Prediabetes? 10 Evidence-Based Steps

Can you reverse prediabetes? Many people can return their A1C or glucose results below the prediabetes range. However, reversal is not guaranteed, and a normal follow-up result does not mean that the future risk of prediabetes or Type 2 diabetes has permanently disappeared.

The strongest evidence supports a structured approach involving balanced eating, regular physical activity, weight management when appropriate, adequate sleep, smoking cessation, cardiovascular-risk management, and repeat laboratory testing.

Prediabetes is not a personal failure or a guaranteed path to Type 2 diabetes. It is an opportunity to identify rising glucose early and build habits that can substantially reduce future risk.

This article provides 10 evidence-based steps that can help improve glucose control without promising a quick fix, restrictive diet, supplement cure, or universal timeline.

What Does It Mean to Reverse Prediabetes?

Prediabetes means that blood glucose is above the normal range but has not reached the diagnostic range for diabetes.

Reversal generally means that an appropriate follow-up laboratory test returns below the prediabetes threshold.

This may include:

• A1C below 5.7%
• Fasting plasma glucose below 100 mg/dL
• Two-hour oral glucose-tolerance result below 140 mg/dL

A person does not necessarily need all three tests. The healthcare professional will decide which test is appropriate to diagnose and monitor the condition.

Reversal Is Not the Same as a Permanent Cure

Normal-range follow-up results do not guarantee that insulin resistance, genetic risk, or future diabetes risk has permanently disappeared.

The more accurate message is:

Prediabetes can often return below the diagnostic range, but continued habits and follow-up testing are needed to maintain the improvement.

Prediabetes Diagnostic Ranges

Prediabetes is diagnosed with laboratory blood tests—not symptoms, a smartwatch, a consumer wellness application, or one home-meter result.

What Does A1C Measure?

A1C estimates average glucose exposure over approximately the previous two to three months.

It does not show every daily high or low and may be less reliable with:

• Some types of anemia
• Hemoglobin variants
• Recent blood loss
• Blood transfusion
• Pregnancy
• Kidney disease
• Conditions that alter red-blood-cell lifespan

A clinician may use fasting glucose or another accepted test when A1C may be misleading.

Does an Abnormal Test Need Confirmation?

When clear diabetes symptoms are absent, an abnormal diagnostic result may be repeated on a different day or confirmed using another accepted test.

Read Prediabetes Information and FAQs for a broader overview of risk factors and screening.

Why Prediabetes Reversal Is Not Guaranteed

Glucose is influenced by more than motivation or food choices.

Factors may include:

• Genetics
• Age
• Body-fat distribution
• Muscle mass
• Physical activity
• Sleep
• Pregnancy history
• Polycystic ovary syndrome
• Sleep apnea
• Liver disease
• Medicines that raise glucose
• Food access
• Income and work schedules
• Chronic stress
• Other medical conditions

Two people following similar plans may experience different laboratory changes.

Prediabetes Is Not a Personal Failure

Use laboratory results as health information—not as a judgment about discipline, character, or body size.

A supportive and realistic plan is more useful than fear, shame, or an extreme diet.

What Does the 58% Diabetes-Prevention Statistic Mean?

The Diabetes Prevention Program was a major randomized clinical trial involving adults at high risk of Type 2 diabetes.

The intensive lifestyle intervention focused on:

• Reducing calorie intake
• Improving eating habits
• Completing at least 150 minutes of moderate physical activity each week
• Losing approximately 5% to 7% of starting body weight when appropriate

The lifestyle intervention reduced the incidence of Type 2 diabetes by 58% compared with placebo during the original study period.

For participants aged 60 or older, the reduction was 71%.

What the 58% Figure Does Not Mean

It does not mean:

• 58% of participants were permanently cured
• Every participant returned to normal A1C
• Every person who loses weight will reverse prediabetes
• Diet and exercise work identically for everyone

It means the structured program significantly reduced progression to Type 2 diabetes.

Step 1: Confirm the Diagnosis and Know Your Numbers

Begin with the exact test and result.

Ask:

• Was the abnormal test A1C, fasting glucose, or an oral glucose-tolerance test?
• What was the exact number?
• How close is it to the diabetes range?
• Does the result need confirmation?
• Could anemia, pregnancy, kidney disease, or another factor affect A1C?

Review Related Health Risks

A clinician may also assess:

• Blood pressure
• Cholesterol and triglycerides
• Family history
• Gestational-diabetes history
• Polycystic ovary syndrome
• Sleep-apnea symptoms
• Liver health
• Medicines that can raise glucose

Create a Retesting Plan

People with prediabetes are generally monitored at least yearly. A clinician may recommend retesting sooner—sometimes within three to six months—when:

• The result is close to the diabetes threshold
• Symptoms develop
• A major treatment or lifestyle change begins
• Pregnancy is planned
• A medicine affecting glucose is started

Step 2: Join a Structured Diabetes-Prevention Program

A structured lifestyle-change program offers more support than general advice to “eat better and move more.”

A CDC-recognized National Diabetes Prevention Program may provide:

• A trained lifestyle coach
• An evidence-based curriculum
• Peer or group support
• Food and activity planning
• Problem-solving skills
• Stress-management strategies
• Online or in-person participation
• Long-term follow-up rather than a short challenge

Why Structured Support Helps

Behavior change becomes easier when a program helps with:

• Setting specific goals
• Tracking progress
• Managing setbacks
• Planning for travel and social events
• Finding affordable food options
• Building activity gradually

Finding a Program

In the United States, ask about:

• A CDC-recognized National DPP provider
• A health-system diabetes-prevention service
• Employer or insurance-supported programs
• Community or pharmacy programs
• Recognized online programs

Outside the United States, ask whether your healthcare system offers an evidence-based diabetes-prevention program.

Step 3: Replace Sugar-Sweetened Drinks

Replacing sugary drinks is one of the clearest, most practical changes because liquid sugar can add a large amount of carbohydrate without creating lasting fullness.

Drinks to Limit More Often

• Regular soda
• Sweetened tea
• Energy drinks
• Fruit drinks
• Large sweetened coffees
• Frequent juice servings

Possible Alternatives

• Water
• Sparkling water without added sugar
• Unsweetened tea
• Coffee with little or no added sugar
• Water flavored with lemon, lime, mint, or cucumber

Whole Fruit Versus Juice

Whole fruit provides fiber, water, and chewing, while juice delivers carbohydrate more quickly and is easier to consume in a large amount.

Whole fruit can fit into a prediabetes eating pattern. Portion and the complete meal still matter.

Start With One Replacement

Replacing one regular sugary drink each day may be more sustainable than attempting to change every meal immediately.

Step 4: Build Balanced, Higher-Fiber Meals

There is no single required prediabetes diet.

A useful eating pattern should be:

• Nutritionally adequate
• Culturally appropriate
• Affordable
• Realistic for the household
• Compatible with health conditions and medicines
• Sustainable over time

Use the Plate Method

Using a nine-inch plate as a general visual guide:

• Half: Non-starchy vegetables
• One quarter: Protein
• One quarter: A quality carbohydrate
• Drink: Water or another suitable low-sugar beverage

Helpful Food Groups

• Leafy greens and other non-starchy vegetables
• Beans and lentils
• Whole fruit
• Oats, barley, and higher-fiber grains
• Fish
• Eggs
• Chicken or other suitable lean proteins
• Tofu and tempeh
• Plain Greek yogurt
• Nuts and seeds
• Avocado and olive oil

Choose Higher-Fiber Carbohydrates More Often

Examples include:

• Beans
• Lentils
• Oats
• Barley
• Whole-grain bread
• Brown rice
• Quinoa
• Whole fruit
• Starchy vegetables in suitable portions

Whole grains and fruit still contain carbohydrate and can raise glucose. Their amount and the complete meal remain important.

Pair Carbohydrates With Protein or Unsaturated Fat

Examples include:

• Berries with plain yogurt
• An apple with peanut butter
• Oatmeal with nuts and seeds
• Whole-grain toast with eggs
• Beans with vegetables and avocado

Pairing may slow digestion, but it does not make the carbohydrate unlimited.

Foods to Limit Without Creating Fear

Foods that may need more planning include:

• Sugar-sweetened drinks
• Large desserts
• Oversized refined-grain portions
• Frequently eaten refined snack foods
• Processed meats
• Frequent deep-fried meals

Frozen vegetables, canned beans, plain yogurt, whole-grain bread, and tinned fish are also technically processed. “Processed” does not automatically mean unhealthy.

Read the Prediabetes Diet Guide for more detailed food and meal-planning information.

Step 5: Work Toward 150 Minutes of Weekly Activity

Physical activity helps muscles use glucose and can improve insulin sensitivity, fitness, blood pressure, mobility, sleep, and mood.

A widely used diabetes-prevention goal is at least 150 minutes of moderate-intensity activity per week.

What Counts as Moderate Activity?

Moderate activity makes you breathe faster while still allowing you to speak in short sentences.

Examples include:

• Brisk walking
• Cycling
• Swimming
• Dancing
• Active household work
• Low-impact fitness classes

You Do Not Need to Start at 150 Minutes

If you are currently inactive, begin with an amount that feels safe and realistic.

Examples:

• A five-minute walk
• A ten-minute walk after one meal
• Walking during part of a lunch break
• Dancing to two songs
• Using a stationary bicycle for several minutes

Increase time or intensity gradually.

Walking After Meals

A brief walk after a meal may be a practical way to add activity and reduce long periods of sitting.

It should complement the weekly activity plan rather than act as a guaranteed glucose-lowering treatment.

Ask for Medical Guidance Before Increasing Activity If You Have:

• Chest pain
• Severe shortness of breath
• Unexplained dizziness or fainting
• Significant heart disease
• Serious joint problems
• Active foot wounds
• Major balance limitations
• Recent surgery or serious illness

Read Best Exercises for Prediabetes for walking, aerobic, strength, and beginner movement options.

Step 6: Add Strength Training and Break Up Sitting

Aerobic activity is important, but muscle-strengthening activity also supports glucose use, mobility, bone health, and long-term function.

Possible Strength Activities

• Chair squats
• Wall push-ups
• Resistance-band rows
• Light dumbbell exercises
• Calf raises
• Body-weight movements

Many adults aim to include muscle-strengthening activity on at least two days each week when medically appropriate.

Start With Technique, Not Heavy Weight

Choose controlled movements and a resistance that allows safe form.

Stop and seek advice if exercise causes:

• Chest pain
• Faintness
• Severe shortness of breath
• Sharp joint pain
• New neurologic symptoms

Break Up Prolonged Sitting

Short movement breaks can complement planned exercise.

Try:

• Standing during a phone call
• Walking for two or three minutes
• Doing gentle chair-supported movements
• Stretching between work tasks

The CDC PreventT2 curriculum includes brief fitness breaks as a strategy for reducing prolonged inactivity.

Step 7: Manage Weight When Appropriate

For people with overweight or obesity, losing approximately 5% to 7% of starting weight can significantly lower the risk of Type 2 diabetes.

For a person weighing 200 pounds, 5% to 7% equals approximately 10 to 14 pounds.

This is an example—not a required target for every reader.

Not Everyone Needs to Lose Weight

Prediabetes can occur in people of any body size.

Some readers may need to:

• Maintain their current weight
• Build muscle
• Increase physical activity
• Improve meal quality
• Treat sleep apnea
• Review glucose-raising medicines

Use a Sustainable Approach

Possible strategies include:

• Reducing sugary drinks
• Building balanced meals
• Planning portions
• Increasing everyday movement
• Strength training
• Improving sleep
• Receiving behavioral or psychological support
• Using medical weight-management treatment when appropriate

Avoid Crash Diets

Very-low-calorie or highly restrictive plans can contribute to:

• Muscle loss
• Nutrient deficiencies
• Fatigue
• Gallstones
• Food anxiety
• Weight regain

Read Natural Weight Loss for a sustainable approach that does not rely on detoxes or extreme restriction.

Step 8: Improve Sleep and Address Possible Sleep Apnea

Sleep affects appetite, energy, activity, stress, food choices, and metabolic health.

Practical Sleep Habits

• Keep a reasonably consistent sleep schedule
• Reduce bright-screen exposure before bed
• Limit late caffeine
• Keep the bedroom dark, quiet, and comfortable
• Create a short wind-down routine
• Avoid using alcohol as a sleep treatment

Possible Sleep-Apnea Signs

Ask for medical assessment if you experience:

• Loud snoring
• Breathing pauses during sleep
• Gasping or choking during sleep
• Morning headaches
• Severe daytime sleepiness
• Unrefreshing sleep

Sleep improvement supports the complete plan but does not replace food, activity, laboratory testing, or medication when needed.

Step 9: Address Cardiovascular and Lifestyle Risks

Prediabetes is not only about glucose. It often occurs with other cardiovascular and metabolic risks.

Review Blood Pressure and Cholesterol

Ask whether you need:

• Blood-pressure measurement
• Cholesterol testing
• Triglyceride testing
• Liver-health evaluation
• Cardiovascular-risk assessment

Stop Smoking

Smoking increases cardiovascular risk and can worsen overall metabolic health.

Evidence-based support may include:

• Behavioral counseling
• Nicotine-replacement therapy
• Prescription treatment
• Telephone or digital stop-smoking services

Manage Stress Without Blaming Stress for Everything

Stress does not single-handedly cause prediabetes, but it can affect:

• Sleep
• Food choices
• Physical activity
• Smoking
• Alcohol use
• Medication routines

Helpful approaches may include:

• Slow breathing
• Walking
• Mindfulness
• Counseling
• Social support
• Enjoyable hobbies
• Reducing unrealistic goals

Alcohol

Alcohol can affect calories, sleep, appetite, liver health, triglycerides, and medicine safety.

People who do not drink do not need to begin for health reasons. People who drink should ask whether alcohol is safe with their medicines and health conditions.

Step 10: Repeat Laboratory Testing and Discuss Medication

Only repeat laboratory testing can confirm whether glucose has improved or returned below the prediabetes range.

How Often Should Testing Occur?

People with prediabetes are generally tested for diabetes at least yearly.

Earlier testing may be appropriate when:

• A1C is close to 6.5%
• Fasting glucose is close to 126 mg/dL
• Symptoms develop
• Pregnancy is planned
• A glucose-raising medicine is started
• A major treatment plan begins

Does Everyone Need Home Glucose Monitoring?

No.

Routine home monitoring is not automatically necessary for every person with prediabetes.

It may be useful in selected situations when recommended by a healthcare professional, such as:

• Symptoms of high or low glucose
• Pregnancy
• A medicine that may cause hypoglycemia
• A structured review of food or activity
• Progression toward the diabetes range

For more information about monitoring versus diagnosis, read Home Diabetes Test: How to Check Blood Sugar Safely.

Can Metformin Help?

Metformin has the strongest long-term evidence among medicines used to prevent or delay Type 2 diabetes.

The American Diabetes Association’s 2026 Standards say metformin should be considered in adults at high risk, particularly people who:

• Are aged 25–59
• Have a BMI of at least 35 kg/m²
• Have fasting glucose of approximately 110 mg/dL or higher
• Have A1C of approximately 6.0% or higher
• Have a history of gestational diabetes

These factors do not automatically mean that metformin is required. A clinician must weigh benefits, contraindications, kidney function, pregnancy plans, side effects, and personal preferences.

Medication Is Not Failure

Prediabetes is influenced by biology, genetics, health conditions, medicines, environment, and lifestyle.

Using metformin or another medically appropriate treatment does not mean that someone failed to eat or exercise correctly.

Long-Term Metformin Monitoring

Long-term metformin use may be associated with vitamin B12 deficiency in some people. A clinician may consider periodic B12 assessment, especially when anemia or neuropathy symptoms develop.

Can Prediabetes Improve Without Weight Loss?

Yes.

Weight loss can be highly effective for people with excess weight, but improvement may also occur through:

• Increased physical activity
• Improved cardiorespiratory fitness
• Strength training and greater muscle mass
• Reduced sugary-drink intake
• Improved carbohydrate quality
• Better sleep
• Treatment of sleep apnea
• Review of glucose-raising medicines

Other Signs of Progress

• Lower A1C or fasting glucose
• Improved blood pressure
• Improved triglycerides
• Greater walking endurance
• Improved strength
• Better sleep
• Reduced sugary-drink intake

Scale weight is only one measure of progress.

How Long Does It Take to Reverse Prediabetes?

There is no universal timeline.

A1C reflects approximately two to three months of glucose exposure, so improvement may become visible within several months.

Some people need longer because of:

• A higher starting result
• Genetic risk
• Medicines that raise glucose
• Sleep apnea
• Other medical conditions
• Difficulty accessing food, care, or safe activity
• Limited social support

Avoid 30-Day Cure Promises

A short challenge may help establish a few habits, but it cannot guarantee a normal A1C or permanent reversal.

Only repeat testing can show whether glucose has returned below the prediabetes range.

Use Process Goals

Examples include:

• Walk after dinner four days this week
• Replace five sugary drinks this week
• Add vegetables to one meal daily
• Complete two strength sessions
• Attend a prevention-program session

Process goals remain useful even when laboratory changes take longer.

Can Prediabetes Return After a Normal A1C?

Yes.

Glucose may rise again because of:

• Reduced activity
• Weight regain
• Aging
• Pregnancy
• Illness
• Sleep disruption
• Medicine changes
• Progression of insulin resistance

Continue the Habits That Helped

A normal result is encouraging, but it is not a reason to stop all follow-up.

Continue:

• Periodic blood testing
• Regular activity
• Balanced meals
• Blood-pressure care
• Cholesterol management
• Sleep and smoking support

Can Apple Cider Vinegar, Cinnamon, or Supplements Reverse Prediabetes?

No supplement, spice, detox, or drink has been proven to reverse prediabetes reliably.

Apple Cider Vinegar

Small studies have examined vinegar and post-meal glucose, but evidence is insufficient to use it as a prediabetes treatment.

Regular or concentrated use may cause:

• Tooth-enamel damage
• Throat irritation
• Digestive symptoms
• Medicine interactions
• Low potassium in selected situations

Cinnamon

Cinnamon can be used as a culinary spice, but evidence does not support presenting it as a reliable reversal treatment.

High-dose cinnamon supplements may cause medicine interactions or liver concerns, depending on the product and amount.

Green Tea

Unsweetened green tea may fit into a healthy beverage pattern, but it is not a substitute for lifestyle support, testing, or medication.

General Supplement Safety

Products marketed for glucose control may:

• Interact with medicines
• Affect the liver or kidneys
• Contain undeclared ingredients
• Cause low glucose when combined with medicine
• Delay effective medical care

Discuss supplements with a pharmacist or qualified healthcare professional.

A Practical Four-Week Prediabetes Starter Plan

This general plan provides a gradual starting structure. It is not a personalized medical prescription.

Do Not Change Everything at Once

Choose one or two actions that are realistic enough to repeat.

A small habit practiced consistently is more useful than an extreme plan abandoned after several days.

How to Track Prediabetes Progress

Track behaviors and health measures that support the goal.

Possible Behavior Measures

• Weekly activity minutes
• Strength sessions
• Sugary drinks replaced
• Meals using the Plate Method
• Sleep schedule consistency
• Prevention-program attendance

Possible Health Measures

• A1C
• Fasting glucose
• Blood pressure
• Cholesterol and triglycerides
• Weight when relevant
• Waist measurement when professionally recommended
• Fitness and strength

Do Not Let Tracking Become Punishment

Tracking should provide useful information—not create fear, guilt, or obsessive checking.

Reduce or change tracking methods if they worsen anxiety, disordered eating, or body-image concerns.

Common Prediabetes-Reversal Mistakes

1. Expecting a Guaranteed Cure

Lifestyle changes can greatly reduce risk, but they do not guarantee a normal result for every person.

2. Treating All Carbohydrates as Harmful

Beans, lentils, whole fruit, milk, yogurt, and whole grains contain carbohydrates and can still be part of a balanced plan.

3. Depending on Supplements

Supplements do not replace structured eating, activity, sleep, testing, and medical treatment.

4. Exercising Too Hard Too Soon

A sudden intense routine can cause injury and make consistency more difficult.

5. Using Shame as Motivation

Prediabetes is not proof of laziness or a lack of willpower.

6. Ignoring Sleep and Cardiovascular Risk

Blood pressure, cholesterol, smoking, sleep apnea, and liver health also matter.

7. Relying on Home Readings for Diagnosis

A glucose meter or CGM cannot confirm prediabetes reversal by itself.

8. Stopping Medication After One Improved Result

Discuss any medicine change with the prescribing clinician.

9. Following an Extreme Diet

Detoxes, severe fasting, and very-low-calorie diets can create medical and nutritional risks.

10. Giving Up After One Setback

A meal, missed workout, illness, holiday, or stressful week does not erase long-term progress.

Questions to Ask Your Healthcare Team

• Which test showed that I have prediabetes?
• What was the exact result?
• Could anything make my A1C inaccurate?
• When should the test be repeated?
• How close am I to the diabetes range?
• Should I join a structured diabetes-prevention program?
• Would a registered dietitian help?
• What physical activity is safe for me?
• Would losing 5% to 7% of my weight be appropriate?
• Can I improve my risk without losing weight?
• Should I consider metformin?
• Do any of my medicines raise glucose?
• Should I be assessed for sleep apnea?
• Do I need blood-pressure or cholesterol treatment?
• Would home glucose monitoring provide useful information?
• What symptoms suggest progression to Type 2 diabetes?
• What result would indicate reversal?

Key Takeaway

Prediabetes can often be reversed, but no diet, workout, supplement, medication, or timeline guarantees the result.

The best-supported approach includes:

• Confirming the diagnosis
• Joining a structured prevention program
• Replacing sugary drinks
• Building balanced, higher-fiber meals
• Working toward 150 minutes of weekly moderate activity
• Adding strength training and movement breaks
• Managing weight when appropriate
• Improving sleep
• Addressing smoking and cardiovascular risks
• Repeating laboratory testing and considering metformin when appropriate

The Diabetes Prevention Program’s 58% result refers to reduced progression to Type 2 diabetes—not a guaranteed cure rate.

Recommended next step: Record your exact A1C or glucose result, confirm when it should be repeated, and choose one food habit and one movement habit that you can begin safely this week.
