Researchers from the Physicians Committee for Responsible Medicine have discovered that adopting a low‑fat, plant‑based diet—without cutting calories or carbs—can help individuals with type 1 diabetes rely on less insulin and spend less on the medication.
Insulin is the hormone that transports glucose from the blood into muscle and liver cells for energy. Because people with type 1 diabetes produce little or no insulin, they must inject it daily. Some also develop insulin resistance, where cells ignore the hormone, leaving glucose stranded in the bloodstream. Dietary fat is a key driver of this resistance.
Study Finds 28% Reduction in Daily Insulin Dose
Lower insulin needs likely stem from improved insulin sensitivity, meaning the body responded more efficiently to the hormone. The same group also experienced a 27% drop in insulin‑related expenses, saving roughly $1.08 each day.
Additional Health Gains
Beyond insulin savings, the vegan cohort shed an average of 11 pounds, showed better blood‑sugar control, and enjoyed healthier cholesterol and kidney‑function markers. These outcomes suggest broader metabolic benefits from a plant‑centric diet.
Why It Matters Amid Rising Insulin Prices
Insulin costs in the United States have surged dramatically, with national spending reaching $22.3 billion in 2022—three times higher than a decade earlier. Prices, after inflation adjustment, rose 24 % between 2017 and 2022. Strategies that reduce daily dosage could therefore translate into substantial savings for patients.
