Calories 120 kcal 120 kcal
Total Fat 14 g 14 g
Monounsaturated Fat 10 g 10 g
Polyunsaturated Fat 1.5 g 2 g
Saturated Fat 2 g 2 g
Oleic Acid (%) 55–83% 60–70%

One slight difference is avocado oil's 2 grams of polyunsaturated fat per tablespoon, compared to olive oil's 1.5 grams. While small, this variation could offer added cholesterol management perks. However, in terms of fat loss, the oils remain comparable due to their similar monounsaturated fat content.

Both oils also deliver vitamin E, an antioxidant that plays a role in maintaining metabolic health. That said, extra virgin olive oil (EVOO) holds a distinct advantage with its rich supply of polyphenols. These compounds provide antioxidant and anti-inflammatory benefits, which indirectly support fat loss by enhancing metabolic function. For instance, Big Horn Olive Oil's Ultra Premium Extra Virgin Olive Oil boasts higher levels of biophenols than standard EVOO, making it a standout choice for those prioritizing weight management. These subtle differences highlight how each oil contributes uniquely to overall health and fat loss strategies.

Fat Loss and Metabolism Research

Recent studies highlight how olive and avocado oils contribute to metabolic health, adding to their well-known nutrient profiles. Research shows that both oils play a role in supporting metabolism and overall fat loss efforts.

Olive oil’s benefits have been extensively studied, especially in the context of the Mediterranean diet. However, newer research suggests that avocado oil may offer comparable advantages. For instance, studies on sucrose-fed rats showed that avocado oil positively influenced glucose, cholesterol, triglycerides, and α-amylase levels in ways similar to olive oil’s effects. Since liver health is closely tied to efficient fat metabolism, these findings are particularly noteworthy.

The monounsaturated fats in olive oil are known to increase fat oxidation after meals and enhance the thermic effect of food, which can boost energy expenditure.

Both olive and avocado oils also play a role in balancing cholesterol levels, a key factor in preventing metabolic syndrome. In animal studies, diets including olive oil or centrifuged avocado oil significantly improved liver health markers, such as direct bilirubin levels. Notably, centrifuged avocado oil reduced direct bilirubin levels by 63%, compared to a 50% reduction observed with solvent-extracted avocado oil.

Here’s a breakdown of how these oils compare in metabolic research:
