The ketogenic diet is a low-carb, high-fat diet that encourages the body to enter a state of ketosis. In this metabolic state, the body burns fat for fuel instead of glucose, which can lead to rapid weight loss. When you limit your intake of carbohydrates, your body starts to use stored fat for energy, reducing body fat. But how long does it take to lose weight on keto?

Weight loss from keto varies from person to person. Generally, if you maintain a daily caloric deficit of around 500-700 calories, you can expect noticeable weight loss after anywhere from 10 to 21 days. However, remember that weight loss is not linear and some may see results sooner.
