While they may seem similar, there are some key differences between LCHF and the ketogenic diet (keto). Both emphasize reducing carbohydrate intake and increasing healthy fats, but keto is typically much more restrictive with only about 5-10% of calories coming from carbs (7).
Additionally, keto often involves tracking macronutrient ratios closely in order to achieve a state called ketosis, where the body burns fat for energy instead of carbohydrates. LCHF does not require strict macronutrient tracking and is often more flexible in terms of carb intake.
