The keto diet is a low-carb, high-fat, and moderate-protein diet that aims to limit carbohydrate intake to fewer than 50 grams per day. This leads to ketosis, where the body uses ketone bodies as its primary energy source instead of glucose. As a result, keto-friendly foods tend to be low in carbohydrates and high in fat. Shiitake mushrooms are keto-friendly as they are low in carbohydrates and fats, with 4.9 grams of net carbs and 2.6 grams of fat per serving. They are also a good source of fibre, protein, niacin, selenium, and various antioxidants. However, they should be consumed in moderation on keto due to their carb content.
