Can a Low Carb Diet Lead to Diabetes?

Research has found that a ketogenic diet can prevent the body from using insulin properly, leading to insulin resistance and an increased risk of type 2 diabetes. Studies have shown that people with type 2 diabetes can lose weight, reduce their need for medication, and lower their A1c levels when following a ketogenic diet for a year. Most studies have compared a low-carb or very low-carb diet, which is less than 26% or 10% of daily calories from carbohydrates, to low-fat diets. The ketogenic diet may be a good option for people with type 2 diabetes because it helps to control carbohydrates.

Studies have shown that metabolic processes are changed when people eat a diet high in fat and low in carbohydrates. The ketogenic diet, also known as the “ketogenic diet” or simply “keto”, was originally created in the 1920s as a treatment for epilepsy and emphasizes fats and proteins while severely limiting carbohydrates and sugars. It is important to note that the distinction between a “ketogenic diet” and the Atkins diet does not make sense because the Atkins diet is also a KD. Researchers found that mice fed the ketogenic diet began to show signs of insulin resistance, which can lead to type 2 diabetes, after just a few days of being on the diet.

Grandl and colleagues compared a high-fat diet to a ketogenic diet in mice by feeding them specific foods and then conducting tests to understand how their bodies reacted to the diets. Several publications have warned that the ketogenic diet (KD) or low-carb, high-fat (LC-HF) diet can have detrimental metabolic effects that lead to the development of diabetes. The study showed that compared to mice on a high-fat diet, those on a low-carb, high-fat ketogenic diet appeared healthier while on the ketogenic diet but they also began to rapidly develop insulin resistance, meaning their livers were less able to respond to insulin and regulate blood sugar levels. High-fiber and low-fat diets have been shown in many studies to be just as effective or more effective than low-carb plans for achieving weight loss and reducing glucose intolerance.
