Type 2 Diabetes Remission in 90 Days? Here’s What Actually Works

In this video, Dr. Columbus Batiste, an interventional cardiologist, breaks down what “reversing” type 2 diabetes really means in medical terms—remission defined as an A1C below 6.5% for at least three months without glucose-lowering medications—and explains how intensive lifestyle and plant-predominant, low-saturated-fat, high-fiber eating patterns can rapidly improve insulin resistance and A1C within about 90 days in some patients, based on randomized trials and meta-analyses rather than hype.

He walks through the biology of intramyocellular fat and insulin signaling, why some low-carb approaches lower glucose without fixing tolerance to whole-food carbohydrates, what large cohorts like Adventist Health suggest about long-term diabetes risk, and why even partial improvements in A1C, weight, inflammation, and medication intensity can substantially reduce heart attack and complication risk—even when full remission isn’t possible—framing food as a powerful, supervised treatment tool alongside standard care.
