Even though there are a lot of calories in avocados, they will not harm your diet. Actually, they are quite beneficial. They contain a large supply of healthy fats that your body actually needs. For some reason calories and fats are frowned upon, and most think the less they consume the better off they will be.
So How Many Calories Are in an Avocado?
A serving is 1/2 of an avocado and contains about 153 calories. One medium sized avocado contains roughly about 306 calories, and one large avocado contains about 322 calories.
Ninety-one percent of those calories come from fat. But don't let that scare you into not eating avocados--a whopping 63 percent of those fat calories come from monounsaturated fats, and 20 percent come from polyunsaturated fats. These are good fats which your body needs, and they will help to lower your bad cholesterol levels and keep your heart healthy.
Even though avocados contain a lot of calories, they also contain a lot of vitamins and minerals which will fill you up fast and keep you feeling full. You are better off to eat them rather than other foods with fewer calories because they will help you to reduce your cravings and calories for non-diet friendly foods in the long-run.
