How much fat is in an avocado?
About 5 g of fat in an ounce, which is about a fifth of a California avocado. Most of it is monounsaturated, the same kind that makes up most of olive oil, and only 0.7 g is saturated. A whole avocado has about five times that, around 25 g of fat and 250 calories.
Avocados get it from both sides. Some people skip them as a high-fat food, and others treat them as a free food you can pile on. The fat in an avocado is mostly the kind that lowers LDL when it replaces saturated fat, and it still has 9 calories a gram like any fat.
What we’d do: eat them. Half an avocado is about 12 g of fat and 1.8 g of saturated fat, which fits easily into any day. They’re at their best in place of something, like cheese on a sandwich or butter on toast.
What’s in it
| California avocado (USDA) | Fat | Saturated | Mono | Poly | Calories |
|---|---|---|---|---|---|
| 1 oz (about a fifth) | 5 g | 0.7 g | 3.2 g | 0.6 g | 50 |
| A whole one (about 5 oz) | about 25 g | about 3.5 g | about 16 g | about 3 g | about 250 |
The whole-avocado row is five times the 1 oz row, so it’s rounded. Florida avocados are leaner, with 3 g of fat and 32 calories in an ounce.
For scale, a tablespoon of olive oil has 14 g of fat, so a whole avocado holds close to two tablespoons of olive oil’s worth of fat. Avocado oil is built almost the same way as the fruit’s fat. A tablespoon has 1.6 g saturated, 9.9 g monounsaturated and 1.9 g polyunsaturated.
Where it does the most good
The 2020 to 2025 US guidelines suggest avocado, nuts or seeds in place of cheese in a dish as a way to cut saturated fat. Two ounces of avocado on a sandwich has 1.4 g of saturated fat, and the ounce of cheddar it replaces has 6.0 g, so the sandwich drops 4.6 g.
The 2026 guidelines list avocados among the whole foods where healthy fats are plentiful. If you’re watching calories, a whole avocado every day is 250 of them, about an eighth of a 2,000 calorie day, and fat makes you fat has the longer answer on fat and weight. The scorer below splits an avocado, or a whole day around one, into its four fats.
