Can Prediabetes Be Reversed? A Dietitian Explains How
Receiving a prediabetes diagnosis can feel scary, confusing, or even overwhelming. Many people immediately wonder: can prediabetes be reversed? Or does it always lead to type 2 diabetes?
The encouraging news is this: prediabetes can often be reversed or delayed, especially when the right lifestyle changes are in place. Decades of high-quality research show that targeted nutrition, movement, and behavior changes can significantly reduce diabetes risk- and in many cases, return blood sugar to normal levels.
In this blog, we’ll cover:
What “prediabetes reversal” actually means
What the research says about reversing prediabetes naturally
The most effective lifestyle changes for prediabetes
When medication may play a role
How a dietitian can help you create a sustainable plan
Let’s break it down.
First, What Does “Prediabetes Reversal” Mean?
When we talk about prediabetes reversal, we’re usually referring to one of two outcomes:
Blood sugar levels returning to the normal (non-prediabetes) range (A1c <5.7)
Preventing or significantly delaying progression to type 2 diabetes
So, can prediabetes go away? For many people, yes- especially with consistent lifestyle support. Studies show that 14-45% of individuals with prediabetes return to normal glucose levels within five years, depending on individual factors and the type of blood sugar elevation.
It’s also important to understand that prediabetes is best viewed as a chronic risk state rather than something that’s “cured.” Even when blood sugar levels return to the normal range, ongoing lifestyle support plays a key role in maintaining those improvements and reducing the risk of future progression.
Can Prediabetes Be Reversed With Lifestyle Changes?
Large randomized controlled trials demonstrate that intensive lifestyle interventions reduce the risk of developing type 2 diabetes by 58% over three years, and the benefits last. Follow-up studies show a 27–34% lower diabetes risk even 10–15 years later.
This is why lifestyle changes for prediabetes are considered first-line treatment by the American Diabetes Association and other major medical organizations.
The Most Effective Lifestyle Changes for Prediabetes
1. Physical Activity Matters- Even Without Weight Loss
One of the most empowering findings from the research is this:
Meeting the physical activity goal alone (≥150 minutes per week of moderate-intensity movement) reduced diabetes risk by 44%, even when weight loss goals weren’t fully met.
That means:
Walking
Strength training
Cycling
Swimming
Any movement you enjoy and can do consistently
This is a huge win for people who feel discouraged by weight-focused messaging.
2. Weight Loss Can Help- But Modest Changes Count
For individuals with overweight or obesity, research suggests that:
3–7% weight loss improves blood sugar control
7–10% weight loss further reduces progression risk
In the Finnish Diabetes Prevention Study:
A 5% weight loss led to a 74% reduction in diabetes risk
Exceeding exercise goals led to an 80% risk reduction
Those who met all lifestyle goals had zero progression to diabetes over 7 years
Importantly, this isn’t about perfection- it’s about realistic, supported change.
3. Nutrition for Prediabetes Should Be Personalized
There is no single “perfect” diet for prediabetes. The American Diabetes Association supports multiple eating patterns shown to reduce diabetes risk, including:
Mediterranean-style eating
Lower-carbohydrate approaches
When people ask can prediabetes be reversed, nutrition is often a central part of the conversation. What matters most is that nutrition for prediabetes is sustainable, adequate (not overly restrictive), and supportive of blood sugar stability over time. Reversal is not about following a rigid plan- it’s about consistency and flexibility.
This is where prediabetes dietitian advice becomes incredibly valuable. A registered dietitian can help you explore what actually works for your body, lifestyle, culture, schedule, and health history- while keeping the recommendations grounded in realistic, evidence-based care.

When Lifestyle Changes Aren’t Enough
In some cases, lifestyle changes alone may not fully normalize blood sugar. When this happens, medication such as metformin may be considered.
Research shows metformin:
Reduces diabetes incidence
Is most effective for individuals under 60, those with higher BMI, or those with a history of gestational diabetes
That said, lifestyle intervention provides greater overall benefit and remains the foundation of care- even if medication is added.
Benefits Go Beyond Blood Sugar
The Da Qing Study showed that diet and exercise interventions didn’t just reduce diabetes risk- they also:
Lowered cardiovascular events
Reduced long-term mortality
So when we talk about reversing prediabetes naturally, we’re also talking about protecting your heart, energy levels, and long-term health.
Can Prediabetes Be Reversed? Final Takeaways
Let’s bring it all together.
Yes, prediabetes can be reversed or delayed for many people
Physical activity alone makes a meaningful difference
Modest, supported changes are more powerful than extremes
Nutrition and lifestyle changes for prediabetes work best when individualized
There is no single “right” way- but there is a supportive, evidence-based path forward. And remember, instead of viewing prediabetes as “cured”, it’s best to continue ongoing lifestyle support.
