Discover the scientific truth about reversing type 2 diabetes through nutrition, complete remission studies, the role of weight loss, and realistic expectations with Dr. Mai Obeid

Quick Answer

Yes, type 2 diabetes can be reversed and complete remission achieved in many patients, especially in early stages, through significant weight loss (10-15% of body weight), very low-calorie diets, and radical lifestyle changes. However, this requires long-term commitment and isn't a quick fix, and not all patients achieve the same results. Complete remission means returning blood sugar to normal without medications for at least 3 months.

What Does Reversing Diabetes or Complete Remission Mean?

Before diving into details, it's important to clarify terminology. When we talk about "reversing diabetes" or "complete remission," we don't mean a permanent cure in the traditional sense, but rather achieving normal blood sugar levels without diabetes medications for an extended period.

Medical Definition of Complete Remission:

According to the American Diabetes Association (ADA) and updated 2025 global standards, a patient is considered in complete remission if:

  • HbA1c level below 6.5% (or below 6% in some definitions)
  • Fasting blood glucose below 126 mg/dL
  • Maintaining these levels for at least 3 months without any diabetes medications
  • No return to medications or insulin

It's important to emphasize that this doesn't mean the disease has completely disappeared, but rather that the body has become capable of managing blood sugar normally without pharmacological intervention.

Scientific Evidence: Can Diabetes Really Be Reversed?

In recent years, several major scientific studies have provided strong evidence for the possibility of reversing type 2 diabetes. Let's review the most important studies:

DiRECT Study (2017-2025):

The British DiRECT study is one of the most important studies in this field. Its updated results published in The Lancet in 2025 included over 300 patients followed for 8 years.

Key Findings:

  • 46% of participants achieved complete remission after one year
  • 36% were still in remission after two years
  • 27% maintained remission after 5 years
  • The key was losing 15 kg or more
  • 70% of those who lost 15+ kg achieved complete remission

The program followed was a very low-calorie diet (800-850 calories daily) for 3-5 months, followed by gradual food reintroduction with continuous weight management support.

DIADEM-I Study (2024):

A groundbreaking African study published in The Lancet in 2024, the first of its kind in sub-Saharan Africa. It showed remarkable results:

  • 47% of participants achieved complete remission after 12 weeks
  • The program used a very low-calorie diet (800 calories daily) for 8 weeks
  • Average weight loss was 14.3 kg
  • Significant improvement in insulin sensitivity and pancreatic function

Look AHEAD Study (2013-2025):

A major American study involving over 5000 patients over 12 years. It showed that:

  • Intensive lifestyle interventions (nutrition + exercise) led to partial or complete remission in 11.5% of participants
  • Patients who lost more than 10% of their weight had 3 times higher chances
  • Health benefits persisted even without achieving complete remission

How Does Nutrition Work to Reverse Diabetes?

To understand how to reverse diabetes, we first need to understand what happens in the body when type 2 diabetes develops.

The Pathological Mechanism:

Type 2 diabetes occurs due to:

  1. Insulin Resistance: Cells become less responsive to insulin
  2. Fat Accumulation in Organs: Fat buildup in liver and pancreas affects their function
  3. Beta Cell Exhaustion: Insulin-producing cells in the pancreas weaken
  4. Chronic Inflammation: Obesity and visceral fat cause chronic inflammation

How Does Nutrition Reverse This Process?

When following a very low-calorie diet and achieving significant weight loss, the following occurs:

  1. Liver Fat Burning: In the first days, the body starts burning accumulated fat in the liver, rapidly improving insulin sensitivity
  2. Reducing Pancreatic Fat: Within weeks, pancreatic fat decreases, allowing beta cells to function more efficiently
  3. Improving Insulin Sensitivity: Weight loss reduces insulin resistance in muscles and tissues
  4. Reducing Inflammation: Loss of visceral fat reduces chronic inflammation
  5. Restoring Beta Cell Function: In early disease stages, beta cells can recover and return to producing insulin normally

A study published in Cell Metabolism in 2026 showed that most blood sugar improvement occurs within the first eight weeks of the diet, with significant improvement in liver and pancreatic function.

Very Low-Calorie Diet (VLCD): The Most Effective Program

The Very Low-Calorie Diet (VLCD) is the cornerstone of most successful diabetes reversal programs.

What is a Very Low-Calorie Diet?

A diet containing 800-1000 calories daily, usually in the form of:

  • Specially prepared meal replacements
  • Specified amounts of non-starchy vegetables
  • Adequate protein to maintain muscle mass
  • Vitamin and mineral supplements
  • Adequate fluid intake

Program Phases:Phase 1: Strict Diet (8-12 weeks)

In this phase, the patient follows an 800-850 calorie daily diet. Most calories come from balanced meal replacements containing:

  • 59 grams protein daily
  • Very limited carbohydrates
  • Small amount of healthy fats
  • All necessary vitamins and minerals

Expected Results:

  • Loss of 10-15 kg
  • Rapid blood sugar decrease within days
  • Significant HbA1c improvement within 8 weeks
  • Decrease in blood pressure and cholesterol

After the first phase, normal food is gradually reintroduced:

  • Increase calories by 200 per week
  • Gradually add food groups: vegetables, protein, whole grains, fruits
  • Teach the patient portion control
  • Develop sustainable healthy eating habits

This is the most important and most difficult phase:

  • Follow a balanced and sustainable diet
  • Monitor weight weekly
  • Immediate intervention if weight increases by 2-3 kg
  • Regular exercise
  • Regular follow-up with nutritionist

Is the Very Low-Calorie Diet Safe?

Yes, under specialized medical and nutritional supervision. Studies have shown it's safe for most patients, but it's necessary to:

  • Not follow it without specialized supervision
  • Exclude cases where it's unsuitable (pregnancy, acute heart disease, eating disorders)
  • Regular follow-up to adjust diabetes medications and avoid hypoglycemia
  • Use balanced meal replacements, not just starvation
  • Take necessary supplements

The Role of Weight Loss: How Many Kilos Should You Lose?

Weight loss is the most important factor in reversing diabetes. But how many kilos should you lose to achieve remission?

Scientific Evidence:

  • 10-15 kg: This is the effective minimum for most patients, especially those with BMI above 30
  • 10-15% of body weight: Generally, losing 10-15% of initial weight is associated with highest remission chances
  • More is better: DiRECT study showed each additional 5 kg increases remission chances

Relationship Between Weight Loss and Remission:

According to DiRECT study:

  • 0-5 kg loss: 7% remission rate
  • 5-10 kg loss: 34% remission rate
  • 10-15 kg loss: 57% remission rate
  • 15+ kg loss: 86% remission rate

These results confirm the importance of significant, not symbolic, weight loss to achieve remission.

Why is Weight Loss So Important?

  1. Reducing Organ Fat: Excess weight means fat accumulation in liver, pancreas, and muscles
  2. Improving Insulin Sensitivity: Visceral fat secretes hormones that increase insulin resistance
  3. Reducing Inflammation: Excess fat causes chronic inflammation that increases insulin resistance
  4. Restoring Pancreatic Function: Reducing fat around pancreas allows beta cells to function efficiently

Other Nutrition Patterns: Do They Work?

Besides the very low-calorie diet, other nutrition patterns have shown positive results:

1. Low-Carb Diet

Many studies have shown the effectiveness of low-carb diets (less than 130 grams daily) in:

  • Significantly lowering blood sugar
  • Reducing medication needs
  • Notable weight loss
  • Improving blood lipid levels

A study in Diabetes Therapy in 2025 showed 17% of patients who followed a low-carb diet (20-50 grams daily) for one year achieved complete remission.

2. Ketogenic Diet

A very high-fat, extremely low-carb diet (less than 20-50 grams daily). Showed good results in:

  • Very rapid blood sugar reduction
  • Significant reduction in required insulin
  • Fast initial weight loss

But challenges include difficulty maintaining long-term and potential side effects.

3. Intermittent Fasting

Different patterns like 16:8 or 5:2 showed benefits in:

  • Improving insulin sensitivity
  • Moderate weight loss
  • Reducing inflammation

A study in Cell Metabolism in 2026 showed significant HbA1c improvement of 0.5-1% within 12 weeks.

4. Mediterranean Diet

A balanced diet rich in vegetables, whole grains, legumes, fish, and olive oil. Studies showed it:

  • Reduces diabetes risk by 20-30%
  • Improves control of existing diabetes
  • Protects cardiovascular health

But its effectiveness in reversing diabetes is less than the very low-calorie diet.

Who Can Achieve Complete Remission? Influencing Factors

Not all diabetes patients can achieve complete remission. There are factors that increase or decrease success chances:

Factors That Increase Remission Chances:

  • Short Disease Duration: Less than 6 years (the more recent the diagnosis, the better the chances)
  • No Insulin Use: Patients not requiring insulin have higher chances
  • Good Pancreatic Function: Good C-peptide level indicates pancreatic insulin production ability
  • Higher BMI at Diagnosis: Patients with significant excess weight benefit more from weight loss
  • Younger Age: Younger patients have better recovery capacity
  • No Advanced Complications: Absence of kidney or nerve complications

Factors That Decrease Remission Chances:

  • Long Disease Duration: More than 10 years (beta cells have deteriorated significantly)
  • Insulin Use: Indicates significant pancreatic function weakness
  • Advanced Complications: Advanced nephropathy or retinopathy
  • Normal Weight or Thinness at Diagnosis: Diabetes may be closer to type 1
  • Presence of Autoantibodies: May be LADA (latent autoimmune diabetes)

What If You Can't Achieve Complete Remission?

Even if you don't achieve complete remission, weight loss and dietary changes offer tremendous benefits:

  • Reducing medication doses
  • Improving blood sugar control and reducing HbA1c
  • Reducing complication risk
  • Improving quality of life
  • Improving cardiovascular health
  • Increasing energy and activity

Essential Lifestyle Changes

Nutrition alone isn't enough. Reversing diabetes requires comprehensive lifestyle changes:

1. Regular Physical Activity

Exercise is essential for:

  • Increasing insulin sensitivity
  • Burning calories and maintaining weight loss
  • Building muscle mass that consumes sugar
  • Improving cardiovascular health

Recommendations:

  • 150 minutes weekly of moderate exercise (brisk walking)
  • Or 75 minutes of vigorous exercise (running, swimming)
  • Resistance training (weights) 2-3 times weekly
  • Reducing prolonged sitting and moving throughout the day

2. Adequate Sleep and Quality

Sleep deprivation increases insulin resistance and appetite. Studies show sleeping less than 6 hours increases diabetes risk by 28%.

Tips for Better Sleep:

  • 7-9 hours sleep daily
  • Regular night sleep (same times)
  • Dark and cool room
  • Avoid screens one hour before sleep
  • Avoid caffeine after noon

3. Stress and Psychological Pressure Management

Chronic stress raises cortisol hormone which increases blood sugar and insulin resistance.

Stress Management Strategies:

  • Meditation and breathing exercises (10 minutes daily)
  • Yoga or tai chi
  • Spending time in nature
  • Hobbies and favorite activities
  • Social support and positive relationships
  • Psychological therapy if necessary

4. Smoking Cessation

Smoking increases insulin resistance and doubles diabetes complication risk.

5. Alcohol Reduction

Alcohol affects blood sugar and may cause dangerous hypoglycemia, especially with diabetes medications.

Realistic Expectations: What You Should Know

It's very important to set realistic expectations about reversing diabetes:

Important Facts:

  1. Not a Quick Magic Cure: Requires strict commitment for months and years, not weeks
  2. Not for Everyone: Only about 30-50% of patients can achieve complete remission even with intensive programs
  3. Maintenance is the Biggest Challenge: Most who achieve remission return to diabetes within 5 years if they don't maintain changes
  4. Requires Continuous Support: Success requires regular follow-up with specialists
  5. Diabetes May Return: Even after remission, returning to old weight or bad habits will bring back diabetes
  6. Not a Failure If You Don't Achieve Complete Remission: Any improvement is success with major health benefits

When Should You Be Cautious?

Don't try to reverse diabetes yourself if:

  • You're using insulin or strong medications (risk of severe hypoglycemia)
  • You have advanced complications in kidneys or heart
  • You have a history of eating disorders
  • You're pregnant or breastfeeding
  • You have other serious diseases

In these cases, work with a comprehensive medical team.

Frequently Asked Questions

Can type 2 diabetes really be completely reversed?

Yes, "complete remission" of type 2 diabetes can be achieved, meaning blood sugar returns to normal without medications for at least 3 months. Recent scientific studies like DiRECT and DIADEM-I showed that 30-50% of patients can achieve this, especially in early stages and with significant weight loss (10-15 kg or more). However, this requires long-term commitment to dietary changes and lifestyle, not a quick fix.

How many kilos should I lose to reverse diabetes?

Research shows that losing 10-15 kilograms or 10-15% of initial body weight is the effective minimum for most patients. DiRECT study showed that 86% of those who lost 15+ kg achieved complete remission, compared to only 7% of those who lost less than 5 kg. The relationship is clear: the more weight loss, the higher the remission chances. But the key isn't just losing weight, but maintaining it long-term.

What is a very low-calorie diet (VLCD) and is it safe?

A Very Low-Calorie Diet (VLCD) is a diet containing 800-1000 calories daily, usually in the form of balanced meal replacements containing all necessary nutrients. Used for 8-12 weeks under specialized medical and nutritional supervision. Yes, it's safe under proper supervision, and studies have shown its high effectiveness in reversing diabetes. But you must not follow it yourself without specialized monitoring, and there are cases where it's unsuitable such as pregnancy or acute heart disease.

Can I reverse diabetes if I'm using insulin?

Insulin use reduces reversal chances but doesn't completely prevent it. Patients using insulin usually have greater pancreatic function weakness, making complete remission more difficult. However, weight loss and dietary changes may allow reducing insulin dose or even stopping it in some cases. But this requires very precise medical monitoring to avoid dangerous hypoglycemia. Consult your doctor before any changes.

How long does it take to reverse diabetes?

Blood sugar improvement starts within days of beginning the very low-calorie diet, and within 8 weeks there's significant decrease in HbA1c and liver and pancreatic fat. But to achieve official "complete remission," blood sugar must remain normal without medications for at least 3 months. Most studies evaluate results after 12 months. But most importantly, this isn't a short-term program - maintaining results requires lifelong commitment to healthy habits.

Will diabetes return after reversing it?

Yes, there's a risk of diabetes returning if you return to old weight and bad habits. DiRECT study showed only 27% of patients maintained remission after 5 years, while most others gradually returned to diabetes. The key is maintaining weight loss and healthy habits for life. This is why successful programs focus heavily on the maintenance and continuous follow-up phase, not just the weight loss phase. Reversing diabetes isn't a permanent "cure," but a condition that must be maintained.

Can I reverse diabetes without losing weight?

For the vast majority of type 2 diabetes patients who are overweight, weight loss is the fundamental and most important factor in reversal. That's because excess weight and fat accumulated in organs (liver and pancreas) are the main cause of the disease. If you're normal weight or thin at diagnosis, your diabetes may be different (perhaps LADA or closer to type 1) and reversal may not be possible. In this case, consult your doctor to reassess the diagnosis.

What is the best diet for reversing diabetes?

The very low-calorie diet (800-1000 calories daily) for 8-12 weeks is the most effective according to scientific evidence, achieving the highest remission rates in major studies (DiRECT and DIADEM-I). Low-carb and ketogenic diets also showed good results but with lower remission rates. More important than the type of diet is achieving significant weight loss (10-15+ kg) and maintaining it. The best diet is one you can commit to long-term under specialized supervision.

Important Medical Disclaimer: The information in this article is for educational purposes only. Reversing diabetes must be done under specialized medical and nutritional supervision. Don't try to apply a very low-calorie diet or modify diabetes medications yourself. This may lead to dangerous hypoglycemia or serious complications. Always consult your doctor and nutritionist before starting any diabetes reversal program. Results vary from person to person based on many factors.
