Understanding the Effectiveness of Therapeutic Carbohydrate Reduction (TCR) in Type 1 Diabetes Management

Managing Type 1 Diabetes (T1D) is a complex, life-long endeavor that requires balancing insulin administration, blood glucose monitoring, and dietary choices. In a groundbreaking Low Carb USA podcast episode, Beth McNally and Matt Miernik shared their transformative journey of adopting Therapeutic Carbohydrate Reduction (TCR) for their son Lachlan, diagnosed with T1D at the age of 9. This episode highlighted the incredible potential of TCR in achieving stable blood glucose levels and improving quality of life for individuals with T1D. Let’s explore how TCR works, the science behind it, and its impact on families living with T1D.

How TCR Works to Stabilize Blood Glucose Levels and Reduce Insulin Needs

Type 1 Diabetes is characterized by the body’s inability to produce insulin, necessitating external insulin administration to regulate blood sugar. Conventional management strategies often include a high-carbohydrate diet paired with large insulin doses. However, this approach frequently results in blood sugar fluctuations, which can lead to long-term complications and an exhausting cycle of highs and lows.

TCR flips this approach on its head. By reducing carbohydrate intake, the amount of glucose entering the bloodstream decreases, which means less insulin is required. As Matt explained in the podcast, this is akin to removing logs from a fire—the smaller the fire (or glucose load), the less water (or insulin) needed to control it.

Beth and Matt’s son Lachlan experienced this transformation firsthand. Within a day of switching to a TCR diet, his blood glucose levels stabilized, and his energy returned. As Beth poignantly described, “We saw our son come back to life again.” This immediate improvement underscores the effectiveness of TCR in managing T1D.

TCR not only stabilizes blood sugar but also reduces the burden of managing complex insulin regimens. With fewer carbohydrates in the diet, insulin dosing becomes more predictable and less prone to errors, creating a safer and more manageable approach to daily T1D care.

Scientific Findings Supporting TCR in T1D Management

Scientific research increasingly supports the role of TCR in achieving superior glycemic control and reducing insulin dependency for individuals with T1D. The recently published position paper by the Society of Metabolic Health Practitioners (SMHP) on TCR for T1D is a landmark document advocating for this approach. The paper highlights key benefits of TCR, including:

Improved Glycemic Control: Studies, such as the 2018 Lennerz et al. research, show that individuals on low-carb diets maintain an average HbA1c of 5.67%, significantly lower than the 7% target recommended by the American Diabetes Association (ADA).

Reduced Insulin Requirements: By minimizing carbohydrate intake, insulin doses can be reduced, leading to more stable blood glucose levels and fewer hypoglycemic episodes.

Lower Risk of Complications: Consistently maintaining blood glucose levels within a near-normal range reduces the risk of long-term complications such as kidney disease, neuropathy, and retinopathy.

The SMHP’s position paper not only provides a comprehensive evidence-based framework but also serves as a valuable resource for clinicians and families exploring TCR as a viable option.

Additionally, the podcast highlighted the groundbreaking Diabetes Control and Complications Trial (DCCT), which showed that tighter glycemic control significantly reduces the risk of complications. TCR offers a practical method to achieve this level of control by addressing blood glucose variability at its root—dietary carbohydrate intake.

Real-World Success Stories

Beth and Matt’s journey with TCR has been nothing short of transformative. Since adopting this approach, Lachlan has thrived. Now 18 years old, he is a high-performing athlete who has qualified for national swimming competitions—a testament to the effectiveness of TCR in supporting both metabolic health and physical performance.

The family’s experience is not unique. The podcast featured discussions about other families and individuals who have successfully implemented TCR, including stories shared during the January 2024 Low Carb USA Boca Raton Symposium for Metabolic Health. This dedicated Type 1 Day event brought together experts like Dr. Ian Lake and Dr. Suzanne Schneider, who shared insights on how TCR can revolutionize T1D care. Many attendees, including healthcare professionals, admitted they gained more insight into T1D management during the event than they had in their entire careers.

During the event, a parent panel featuring Beth McNally and Lester Hightower offered a deeply personal glimpse into the challenges and successes of managing T1D through TCR. The panel underscored the importance of community, collaboration, and evidence-based approaches in overcoming the complexities of T1D.

Addressing Misconceptions and Double Diabetes

A key topic discussed in the podcast was the phenomenon of “double diabetes,” where individuals with T1D develop insulin resistance akin to Type 2 Diabetes. This condition often arises from conventional high-carb, high-insulin management strategies, which can lead to metabolic stress and increased health risks.

TCR helps mitigate the risk of double diabetes by reducing the need for large insulin doses, thereby minimizing insulin resistance. As Matt emphasized, “You are effectively carbohydrate intolerant. Reducing carbs makes it easier to manage the condition and prevents insulin resistance from developing.”

Double diabetes poses significant health risks, including an increased likelihood of cardiovascular disease, obesity, and further complications associated with insulin resistance. The podcast highlighted how TCR addresses these risks by focusing on a low-carbohydrate, high-protein nutritional strategy that supports metabolic health while reducing the stress on insulin-dependent systems.

Empowering Patients and Clinicians with Knowledge and Resources

The SMHP’s position paper is a game-changer in the T1D community. It advocates for open access and clinical support for patients choosing TCR, emphasizing the importance of informed decision-making. By equipping clinicians with evidence-based guidelines, the paper aims to foster a collaborative approach to care, where families and healthcare providers work together to optimize outcomes.

The podcast highlighted the need for greater education among clinicians. Many healthcare providers lack training in nutrition and are hesitant to support TCR due to outdated guidelines and misconceptions. The SMHP paper and resources like the free Low Carb USA YouTube Type 1 diabetes videos aim to bridge this gap, empowering clinicians to confidently support TCR as an option for their patients.

Beth and Matt encouraged families to share the SMHP position paper with their healthcare providers to initiate informed discussions about TCR. They emphasized that TCR is not a one-size-fits-all solution but a personalized approach that requires collaboration and support from a knowledgeable medical team.
