A new study has found that plant-based diets may offer a powerful tool in managing Type 2 diabetes, adding to the growing list of health benefits linked to plant-based eating.
The study, published in the American Journal of Lifestyle Medicine, followed participants who joined a 12-week online program led by physicians. The program provided guidance on adopting a plant-based diet and helped participants stay accountable throughout the process.
While past research has already linked plant-based diets to heart health and improved metabolism, many doctors have been slow to recommend them. According to Vegconomist, this is partly due to limited nutrition training in medical education, short appointment times, and lack of insurance support.
However, this study suggests that virtual programs can overcome those barriers. By offering expert support online, patients receive credible nutrition advice in a more flexible and accessible way.
Among the 58 participants who completed the program, many saw significant improvements in their health. On average, they lost weight and lowered both their cholesterol and A1C levels — a key marker for blood sugar. Nearly 25% of participants were able to reduce their insulin doses. The cost of the program, according to Vegconomist, was similar to a typical doctor’s visit copay.
This research comes at a critical time. Experts warn that the global diabetes crisis is accelerating, with over 1 billion people projected to have the condition by 2050.
Plant-based diets may also lower the risk of other serious health problems, such as heart disease, while supporting better digestion and metabolism. In addition to personal health benefits, eating fewer animal products can also help reduce greenhouse gas emissions. According to the United Nations Food and Agriculture Organization, meat and dairy production is responsible for over 14% of global climate pollution.
“If more people adopt plant-based diets,” the study’s lead author said, “we could improve health outcomes and reduce environmental damage at the same time.”
This online approach could make it easier for healthcare professionals to recommend sustainable, science-backed lifestyle changes to their patients—potentially changing how chronic conditions like diabetes are managed in the future.
