Diabetes isn’t just about eating too much sugar. It’s about your body’s intricate dance with insulin, your genetic blueprint, and how stress literally changes your blood chemistry. The woman whose A1C dropped from 7.4 to 4.9 through lifestyle changes isn’t “cured” in the way we think of curing a cold—she’s managed to reset her system, but the underlying tendency remains. This isn’t a failure of willpower; it’s the complex reality of a disease that affects over 37 million Americans.
When a 5'1" man loses 70 pounds and gets off diabetes medication, it’s not magic—it’s metabolic rebalancing. The Penn Jillette story isn’t an exception; it’s evidence of how powerful lifestyle changes can be when you understand what’s really happening in your body. But most doctors don’t have time to explain these nuances during a 15-minute appointment.
Can You Actually “Cure” Diabetes or Is It Just Management?
The evidence suggests diabetes exists on a spectrum, not as a binary condition. What we can verify is that type 1 diabetes involves autoimmune destruction of insulin-producing cells—a permanent condition where the body attacks itself. Type 2 diabetes, however, involves insulin resistance and eventual beta-cell exhaustion. This remains unconfirmed but some research indicates these cells can recover if given sufficient rest through significant weight loss or other interventions.
Think of it like a muscle that’s been overworked. You can rest it, strengthen it, and make it function better, but the underlying tendency to fatigue remains. The line between “diabetes” and “not diabetes” isn’t a wall but a gradient. When someone with type 2 diabetes achieves an A1C below 6.5% through lifestyle changes, they’ve essentially moved back across that line—but the line itself is still there.
Why Your A1C Level Doesn’t Tell the Whole Story
What we can verify is that A1C measures average blood sugar over three months, not moment-to-moment fluctuations. This remains unconfirmed but many patients experience periods of high blood sugar without experiencing acute symptoms that would send them to the emergency room. The evidence suggests that consistently elevated glucose levels, even if not causing immediate symptoms, create long-term damage to blood vessels, nerves, and organs.
Consider the case of someone with an A1C of 18—hospitalization was necessary not because of a single spike, but because their system had been operating in crisis mode for months. The woman who maintained an A1C of 4.9 for two years but is still classified as diabetic illustrates this perfectly. Her body has achieved normal function through intervention, but the underlying tendency remains.
How Genetics and Hormones Create Unfair Disadvantages
The evidence suggests genetics plays a significant role in diabetes susceptibility. What we can verify is that conditions like PCOS correlate strongly with type 2 diabetes development. This remains unconfirmed but estrogen appears to offer protective effects—explaining why women often develop type 2 diabetes after menopause when estrogen levels decline.
When scientists removed estrogen receptors from endothelial cells in mice or removed ovaries from female mice, type 2 diabetes developed at higher rates. For women in perimenopause experiencing irregular periods, intense cravings, and night sweats, managing diabetes becomes exponentially more challenging. Stress compounds these challenges—many patients report clear correlations between major life stressors and spikes in their blood sugar levels.
The Double Standard in Weight and Health Perception
What we can verify is that weight plays a crucial role in diabetes development and management. The evidence suggests that being 40 pounds overweight places many individuals in a range they perceive as “healthy” when it’s not. Penn Jillette’s experience—losing over 100 pounds to reverse his pre-diabetes—demonstrates how substantial weight loss can dramatically improve metabolic function.
When a 5'1" man loses 70 pounds, that’s not just weight loss—it’s a 40% reduction in body mass. His subsequent ability to stop diabetes medication isn’t miraculous; it’s metabolic rebalancing. The issue becomes complex when we consider access—patients with long COVID, limited income, or chronic fatigue may lack the means to implement these changes, creating a health equity crisis.
Why “Remission” Isn’t the Same as “Cured”
The evidence suggests that achieving diabetes remission requires sustained lifestyle changes. What we can verify is that remission means your blood sugar levels have returned to normal without medication, but the underlying tendency remains. This remains unconfirmed but maintaining remission typically requires ongoing vigilance—what worked to achieve remission may not be sufficient to maintain it.
Think of it like learning to ride a bike. Once you’ve mastered it, you don’t forget how—but if you stop practicing, you might wobble when you start again. The same principle applies to metabolic health. The person who brings their A1C down from 6.4 to 5.4 through diet isn’t “cured” in the traditional sense; they’ve reset their system but must maintain those changes to stay in remission.
The Role of Stress in Blood Sugar Fluctuations
What we can verify is that stress hormones like cortisol directly impact blood sugar levels. The evidence suggests that major life stressors—like house purchases, grief, or chronic work pressure—cause measurable increases in blood glucose. This remains unconfirmed but many patients report their diabetes management becomes significantly more challenging during high-stress periods.
For someone diagnosed during a particularly stressful time, distinguishing between stress-induced glucose spikes and underlying diabetes can be difficult. The key difference lies in consistency—diabetes causes persistent metabolic changes, while stress typically causes temporary fluctuations. However, chronic stress can precipitate or worsen diabetes, creating a feedback loop that’s hard to break.
Why Some Patients Need Medication Despite Lifestyle Changes
The evidence suggests that diabetes progression varies significantly between individuals. What we can verify is that some patients achieve excellent blood sugar control through lifestyle changes alone, while others require medication regardless of their efforts. This remains unconfirmed but genetic factors likely explain much of this variability.
When primary care doctors recommend diet and exercise, they’re acknowledging these are foundational—but they’re also aware that these interventions don’t work equally for everyone. Factors like income, time availability, and access to healthy food dramatically impact a patient’s ability to implement these changes. For some, medication becomes necessary not because of failure, but because of biological necessity.
The Emerging Science of Islet Cell Transplantation
What we can verify is that research into diabetes cures is advancing rapidly. The evidence suggests that islet cell transplantation, particularly when combined with immune-modulating drugs like Tegopurbart, may offer functional cures for some patients. This remains unconfirmed but early studies showing 12 people achieving functional cures are promising.
The Eledon study represents a significant breakthrough—not by regenerating lost cells, but by protecting transplanted cells from immune rejection. For patients with type 1 diabetes who’ve lost their insulin-producing cells, this approach offers hope of normal metabolic function without the need for lifelong insulin therapy. Phase 2 trials including adults with kidney problems suggest broader applicability.
The Danger of “Double Diabetes”
The evidence suggests that some individuals develop characteristics of both type 1 and type 2 diabetes. What we can verify is that this condition, sometimes called “double diabetes,” occurs when someone with type 1 diabetes develops insulin resistance typical of type 2 diabetes. This remains unconfirmed but appears to be increasingly common, possibly related to rising obesity rates even among type 1 diabetes patients.
In type 1 diabetes, the immune system destroys insulin-producing beta cells—these cells are gone for good. In type 2 diabetes, beta cells don’t necessarily die but become exhausted and dysfunctional. The overlap creates a complex condition that requires careful management of both autoimmune and metabolic aspects.
Why Some Patients Develop Diabetes as Adults
The evidence suggests that type 1 diabetes can develop at any age, not just in childhood. What we can verify is that adult-onset type 1 diabetes often progresses differently than childhood onset, sometimes developing more gradually and being initially misdiagnosed as type 2 diabetes. This remains unconfirmed but appears to be increasing in prevalence.
For the father who developed type 1 diabetes in his mid-50s, the diagnostic journey highlights how many medical professionals still associate type 1 diabetes exclusively with children. This misperception can lead to delayed diagnosis and inappropriate treatment approaches. The autoimmune nature of type 1 diabetes means it can emerge decades after initial immune changes begin.
How the Definition of Diabetes Creates Confusion
The evidence suggests that diabetes exists on a continuous spectrum rather than as a discrete condition. What we can verify is that the diagnostic threshold of A1C 6.5% creates an artificial boundary that doesn’t reflect biological reality. This remains unconfirmed but many patients function perfectly with A1Cs just below this threshold while others struggle with levels just above it.
Think of it like temperature—there’s no magical point where water suddenly becomes “hot.” Similarly, the transition to diabetes occurs gradually. The arbitrary nature of diagnostic thresholds explains why some patients with “normal” A1Cs still experience diabetes-related complications, while others with slightly elevated levels remain asymptomatic.
The Critical Role of Social and Economic Factors
What we can verify is that diabetes management is heavily influenced by social determinants of health. The evidence suggests that factors like income, access to healthy food, transportation to medical appointments, and time for exercise dramatically impact outcomes. This remains unconfirmed but the disparities in diabetes prevalence and outcomes between socioeconomic groups are stark.
For patients with long COVID experiencing post-exertional malaise, or those relying on food banks, diabetes management becomes exponentially more challenging. The woman whose medication caused rapid weight gain illustrates how treatment itself can create new obstacles. These systemic barriers mean that while individual responsibility plays a role, it’s far from the whole story.
What “Remission” Really Means for Your Future Health
The evidence suggests that achieving diabetes remission significantly reduces long-term health risks. What we can verify is that remission means your body has regained normal metabolic function, but you remain at higher risk than someone who never had diabetes. This remains unconfirmed but statistical data shows that even after years in remission, former diabetes patients experience higher rates of cardiovascular disease and other complications.
Think of it like scarring—a healed wound isn’t identical to untouched skin. Similarly, a body that has recovered from diabetes retains some metabolic memory. The key difference between remission and cure lies in permanence—remission requires ongoing maintenance, while a true cure would eliminate the underlying tendency forever. Current science suggests we’re closer to effective management than true cures, but research continues to advance.
