Bottlenose dolphins experience higher blood glucose levels when fasting overnight, entering a state similar to diabetes. Scientists believe studying this "diabetic switch" in dolphins could help develop a cure for human diabetes. Dolphins have a different diet and metabolism that allows their brains to remain nourished even when fasting for long periods, as they produce high glucose levels without needing to absorb carbohydrates. Researchers hope to identify a similar regulatory mechanism in humans that could control blood glucose levels independent of insulin.
