Deep dives
Understanding the Ketogenic Diet
The ketogenic diet is characterized by a significant reduction in carbohydrate intake, which forces the body to burn fat for fuel instead of sugar. Originally developed in the 1920s as a treatment for epilepsy, this diet has gained popularity for weight loss and managing type 2 diabetes. Daily meal examples include low-carb foods like omelets, fatty meats, and non-starchy vegetables, highlighting the restrictive nature of this diet. Although some people thrive on keto, adhering to it can be challenging, especially for vegetarians due to limited food options such as avocados and nuts.
