The iLet from Beta Bionics is unlike other insulin pumps else on the market. Instead of juggling carb ratios, correction factors, or long lists of settings, the iLet only requires one input when you start: your weight. From there, the pump uses its own algorithm to handle insulin delivery and learn the user, aiming to simplify diabetes management in a way that feels almost hands-off.

In my latest episode, I sat down with Dr. Mike Natter — an endocrinologist living with type 1 diabetes himself — to talk about what it’s really like to wear the iLet pump for two months. Dr. Natter has a unique perspective: not only does he understand the clinical side of diabetes care, but he also lives with the daily realities of the condition. That mix of professional and personal insight made this conversation especially valuable.

One of the biggest takeaways from Dr. Natter’s experience is how the iLet changes the way you think about bolusing insulin. The system doesn’t rely on traditional carb counting or complex manual adjustments. Instead, it works in the background, learning and adapting over time. For many users, this could mean less mental load and fewer day-to-day decisions — something people with diabetes often describe as “diabetes burnout.”

While other insulin pumps offer users more control through features like customizable profiles, the iLet’s strength lies in its simplicity. That tradeoff — control versus ease of use — is at the heart of whether the iLet will be a good fit for someone’s lifestyle.

Dr. Natter shared that while no device is perfect, the iLet offers something different: a system designed to take the burden off the user as much as possible. For those who find diabetes management overwhelming or want a more automated approach, that simplicity could be a game-changer.

This episode is not just about the specs of the pump — it’s about how technology like the iLet can fit into real life.
