Olives, a savory Mediterranean fruit, are often cured and eaten whole as a tangy, salty snack. Many people also enjoy them on pizzas and salads or processed into oil or tapenade.
They’re known for being rich in beneficial fats and are included in the popular Mediterranean diet, so you may wonder whether olives can help you lose weight.
This article explains whether olives aid weight loss.
Olives may affect your weight in a variety of ways.
Olives have a notably low calorie density.
Calorie density is a measure of the number of calories in a food relative to the food’s weight or volume (in grams). In general, any food with a calorie density of 4 or more is considered high.
Whole black or green olives have a calorie density of 1–1.5.
Olives also boast healthy unsaturated fats, which differ from saturated and trans fats due to their chemical structure. All fats contain the same amount of calories, but unsaturated fats affect your body beneficially (
A 60-day study in 32 women compared diets high monounsaturated and polyunsaturated fats with normal diets. The diet high in monounsaturated fats resulted in weight loss of up to 4.2 pounds (1.9 kg), plus lower fat mass, body mass index (BMI), and waist circumference (
Furthermore, a large review of low calorie diets revealed that high fat eating patterns more often lead to weight loss than low fat ones (
The Mediterranean diet, which emphasizes whole foods and seafood while limiting processed foods, may boost weight loss. Olives, olive oil, and other healthy fats are a key component of this diet (

Although olives have a low calorie density and may aid weight loss in several ways, it’s best to enjoy them in moderation due to their high salt content, as well as their overall fat content.
Furthermore, if you don’t closely monitor portion sizes, olives’ calorie count can add up quickly.
To keep your saturated fat intake within the recommended guidelines, it’s best to limit your intake to 2–3 ounces (56–84 grams) — about 16–24 small- to medium-sized olives — per day.
Though olives may aid weight loss, they’re high in salt and fat — and eating too many of them may offset your weight loss success. As such, you should moderate your intake, limiting yourself to a few ounces at most per day.
