    Fasting-Mimicking Diet May Reverse Diabetes

    The fasting-like diet promotes the growth of new insulin-producing pancreatic cells that reduce symptoms of type 1 and type 2 diabetes in mice, according to the study on mice and human cells led by Valter Longo, director of the Longevity Institute at the USC Leonard Davis School of Gerontology.

    Cycles of a fasting-mimicking diet and a normal diet essentially reprogrammed non-insulin-producing cells into insulin-producing cells. By activating the regeneration of pancreatic cells, the researchers were able to rescue mice from late-stage type 1 and type 2 diabetes. They also reactivated insulin production in human pancreatic cells from type 1 diabetes patients.

    The reprogrammed adult cells and organs prompted a regeneration in which damaged cells were replaced with new functional ones.

    In type 1 and late-stage type 2 diabetes, the pancreas loses insulin-producing beta cells, increasing instability in blood sugar levels.

    The study showed a remarkable reversal of diabetes in mice placed on the fasting-mimicking diet for four days each week. They regained healthy insulin production, reduced insulin resistance and demonstrated more stable levels of blood glucose. This was the case even for mice in the later stages of the disease.

    The diet cycles switched on genes in the adult mice that are normally active only in the developing pancreases of fetal mice. The genes set off production of a protein, neurogenin-3 (Ngn3); thus, generating new, healthy insulin-producing beta cells.

    Longo and his team also examined pancreatic cell cultures from human donors and found that, in cells from type 1 diabetes patients, fasting also increased expression of the Ngn3 protein and accelerated insulin production. The results suggest that a fasting-mimicking diet could alleviate diabetes in humans.

    Longo and his research team have amassed evidence indicating several health benefits of the fasting-mimicking diet. Their study demonstrated that the fasting-mimicking diet reduced risks for cancer, diabetes, heart disease and other age-related diseases in human study participants who followed the special diet for five days each month in a three-month span.

    Prior studies on the diet have shown potential for alleviating symptoms of the neurodegenerative disease multiple sclerosis, increasing the efficacy of chemotherapy for cancer treatments, and decreasing visceral fat. (Tasnim News Agency)
