The Fasting Mimicking Diet (FMD) shows promise in treating diabetes, with some participants able to reduce medication after the diet, according to a 12-month study. However, the diet alone is insufficient for diabetes reversal, as significant weight loss is required. The study suggests that for optimal results, one must also adopt lasting dietary changes in conjunction with FMD to achieve substantial weight loss and potentially reverse diabetes. This approach is advocated over simply managing the disease with medication and moderate health changes.
