Avocados are considered to be one of the best superfoods for anyone following a ketogenic diet. This fruit is considered unusual as it is high in fat, which means it contains a higher number of calories than other vegetables and fruit. The average amount of calories of a whole avocado comes in at 300 kcal, and when compared to the same amount of other vegetables such as broccoli, they only come in around 40 kcal. However, the fat found in avocados is considered to be good fats as they are mainly unsaturated. They are low in carbs, have almost no sodium or cholesterol, and most importantly, are full of nutrients. As your body goes into ketosis, it will look for fat to burn, and avocados help with that process perfectly.
