How many calories are in an avocado depends mostly on size. A practical reference is about 160 calories for 100 g, around 320 calories for one medium whole avocado, and closer to 400 calories for a larger one. Avocados are nutrient-dense rather than low-calorie, so they are usually best understood by portion, not by assuming all avocados are the same size.

Part 1. Avocado Calories by Portion

Half a medium avocado is often about 160 calories. One medium whole avocado is roughly 320 calories, while a larger avocado can reach around 400 calories. That is why avocado toast, salads, and bowls often vary more than expected.

Per 100 g, avocado provides about 2 g protein, 8.5 g carbs, 6.7 g fiber, 15 g fat, and useful potassium, folate, vitamin K, and vitamin C. The fat content is high, but it is one reason avocado is so filling.

Part 3. Are Avocados Good for Weight Loss

Avocados can work well in weight-loss plans because they are satisfying and rich in fiber and healthy fats. The main thing to watch is portion size. A quarter to half an avocado often fits more easily into daily calorie targets than a full large fruit.
