The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet that can help your body enter a state of ketosis. In this state, your body burns fat for fuel instead of glucose, resulting in weight loss and potential health benefits such as improved blood sugar control, increased energy levels, and reduced inflammation. While the diet may not be right for everyone, it can be a sustainable and effective way to achieve weight loss and improve overall health when followed properly.
