Monounsaturated Fats in Olive Oil: Weight Loss Benefits
Want to lose weight while improving your health? Olive oil might be the key. Research shows that olive oil, rich in monounsaturated fats (MUFAs), can support weight loss by improving fat burning, controlling hunger, and reducing abdominal fat. Here's why it works and how to use it:
- Boosts fat burning: MUFAs, especially oleic acid in olive oil, increase fat oxidation after meals.
- Curbs hunger: Oleic acid produces OEA, a compound that reduces appetite and keeps you full longer.
- Improves fat distribution: Promotes loss of harmful belly fat while preserving healthy subcutaneous fat.

Research on Olive Oil and Weight Management
Olive Oil in Controlled Diet Studies
A randomized trial involving 41 overweight women revealed that consuming 25 mL of extra virgin olive oil daily, as part of a calorie-restricted diet, led to an 80% greater fat loss compared to soybean oil consumption. Specifically, participants lost an average of 2.4 kg versus 1.3 kg in the soybean oil group (P = 0.037). Other studies have shown that swapping saturated fats for monounsaturated fats, like those in olive oil, can lead to modest weight loss in men. In fact, adding just 7 grams (about half a tablespoon) of olive oil daily has been linked to a 0.09 kg reduction in body weight.
While these findings are short-term, they provide a foundation for understanding the long-term effects of olive oil in Mediterranean-style diets.
Long-Term Results in Mediterranean Diets
The EPIC-PANACEA project, which followed 373,803 Europeans, found that sticking closely to a Mediterranean diet was associated with a 5-year weight change of –0.16 kg and a 10% lower risk of becoming overweight or obese. Additionally, for every unit increase in adherence to a Mediterranean diet, participants gained 0.04 kg less over five years. A meta-analysis of cohort studies further supported this, showing a 9% lower risk of developing overweight or obesity with greater adherence to the Mediterranean diet.
Another study published in the American Journal of Clinical Nutrition found that consuming seven grams of olive oil daily was linked to reduced weight gain over time. A two-year intervention in Alicante, Spain, also demonstrated that older adults following a Mediterranean diet experienced notable reductions in body weight, fat mass, BMI, and waist circumference compared to a control group that only received written nutritional guidance.
Flynn and Reinert reported even more striking results: 80% of women on a plant-based olive oil diet (PBOO) lost at least 5% of their body weight, compared to just 31% of women on a reduced-fat diet, despite the PBOO diet being higher in calories. As they explained:
"Both the lower‐fat diet recommended by the NCI and the PBOO diet produced weight loss, but significantly more women (80%) lost at least 5% of their baseline weight when their first 8 weeks of weight loss diet were on the PBOO diet than when their first diet was the NCI (31%)".

How Monounsaturated Fats Support Weight Loss
Olive oil does more than just balance calories - it plays a key role in supporting weight loss, thanks to its monounsaturated fats, particularly oleic acid. These healthy fats aid in burning fat, managing hunger, and even influencing how body fat is distributed.
Boosting Fat Burning
Monounsaturated fats in olive oil are more efficiently oxidized than saturated fats. For instance, research highlights that oleic acid (a key fat in olive oil) is burned at a higher rate than stearic acid, a saturated fat. Studies show that consuming extra virgin olive oil leads to increased fat oxidation and calorie burning after meals, especially in individuals with larger waistlines . In fact, meals rich in olive oil have been found to enhance post-meal calorie expenditure and improve appetite regulation.
Controlling Hunger
Monounsaturated fats also help curb hunger. When your body processes oleic acid, it produces oleoylethanolamide (OEA), a compound linked to reduced appetite and lower food intake. Research has shown that diets containing high-oleic oils, such as virgin olive oil, significantly reduce energy intake at subsequent meals, keeping you fuller for longer . This dual benefit of appetite control and satiety makes olive oil an excellent dietary addition for weight management.
Shaping Body Fat Distribution
The benefits of olive oil extend to how fat is stored in the body. Studies reveal that a diet rich in monounsaturated fats can lead to better fat loss compared to diets high in saturated fats. For example, one study found that participants on a MUFA-rich diet lost 1.7 kg of fat, while those on a saturated fat diet gained about 1 kg. In people with metabolic syndrome, daily consumption of extra virgin olive oil over two months resulted in reductions in body weight, waist size, and BMI. Additionally, the study noted healthier fat distribution, with a decrease in visceral fat and an increase in subcutaneous fat. This shift supports overall health and reduces risks tied to abdominal fat.
| Benefits of Replacing Saturated Fats with Monounsaturated Fats |
|---|
| Increased weight and fat loss |
| Better muscle and lean tissue preservation |
| Lower blood pressure |
| Greater post-meal fat burning (instead of carbohydrate burning) |
| Reduced post-meal triglycerides |
| Higher post-meal HDL (good cholesterol) |
These findings highlight the importance of choosing the right type of fat in your diet. Replacing saturated fats with monounsaturated fats can lead to reduced body fat, particularly around the abdomen, even without changing overall calorie or fat intake. By improving fat burning, appetite control, and fat distribution, monounsaturated fats offer a well-rounded approach to weight loss.

How to Use Olive Oil for Weight Loss
Science-backed tips can help you weave olive oil into your weight loss plan effectively. When paired with smart swaps, portion awareness, and mindful calorie choices, olive oil can support your efforts.
Replacing Other Fats with Olive Oil
One of the easiest ways to make olive oil part of your weight loss strategy is by swapping it for less healthy fats like butter or margarine. Extra virgin olive oil (EVOO) is especially recommended because it contains more antioxidants and beneficial compounds. Use EVOO in salad dressings or marinades, and regular olive oil for moderate-heat cooking. Interestingly, research suggests that consuming a tablespoon of olive oil before meals can help you feel fuller and reduce overall calorie intake.
However, while olive oil has its perks, keeping an eye on portions is essential to avoid overloading on calories.
Portion Control and Calories
Olive oil is calorie-dense, so moderation is crucial. Just one tablespoon (15 mL) packs 119 calories and 13.5 grams of fat. Experts suggest sticking to 1–2 tablespoons per day, with 1 tablespoon being ideal for those aiming to lose weight. Programs like Weight Watchers also emphasize tracking olive oil consumption due to its calorie content. For the best results, combine olive oil use with a balanced diet and regular physical activity.
This mindful approach ensures olive oil supports your goals without derailing them.
Olive Oil vs Other Common Fats
When compared to other fats, olive oil stands out as a healthier option. Here's how it measures up:
| Fat Type | Calories (per tbsp) | Saturated Fat | Key Benefits |
|---|---|---|---|
| Extra Virgin Olive Oil | 120 | 2g | High in monounsaturated fats and polyphenols; supports weight management |
| Butter | 102 | 7.2g | High in saturated fat, which can raise LDL cholesterol |
| Margarine | ~100 | 2–3g | Often processed; may contain harmful trans fats |
The American Heart Association advises limiting saturated fat intake to no more than 6% of your daily calories, making olive oil a better choice over butter or margarine. Research also shows that replacing these fats with olive oil can help minimize weight gain over time. Additionally, the polyphenols in olive oil act as antioxidants - something butter lacks - which may further aid in weight control and overall health.
Conclusion: Olive Oil for Weight Loss
Research highlights how the monounsaturated fats in olive oil play a role in effective weight management. Studies repeatedly show that swapping out saturated fats for olive oil can lead to noticeable fat loss. For instance, one study revealed that participants on a diet rich in monounsaturated fats lost 3.75 pounds (1.7 kg) of fat, while those consuming saturated fats gained weight, particularly around the abdomen.
The benefits stem from olive oil's ability to boost fat oxidation, increase metabolic rate, and keep you feeling fuller for longer. In fact, long-term research involving over 400,000 participants in Spain found that higher olive oil consumption was linked to a lower risk of early mortality. These metabolic advantages make choosing high-quality olive oil crucial for achieving the best results.
Choosing Quality Olive Oil for Best Results
The quality of olive oil can significantly impact its effectiveness. Studies show that olive oil with a phenol content above 366 mg/kg delivers better weight loss outcomes compared to refined olive oil with just 2.7 mg/kg of phenols.
"It could be labeled 'extra virgin,' but you wouldn't know if it had phenols, which account for the health benefits of extra virgin olive oil." - Mary Flynn, Nutrition Researcher at Brown University
Premium options, like Ultra Premium Extra Virgin Olive Oils from Big Horn Olive Oil, are minimally processed and carefully sourced, ensuring they retain the highest levels of beneficial compounds. These oils typically contain 70–85% monounsaturated fatty acids, with oleic acid being the key component that supports weight management.
Key Points for Health-Focused Readers
Incorporating olive oil into your weight management plan is both practical and effective. Research suggests that increasing olive oil intake by just ½ tablespoon (7 g) daily is linked to a slight reduction in body weight, with participants averaging a 0.09 kg decrease.
For best results, focus on substitutions rather than simply adding more calories. Replace butter, margarine, or other vegetable oils with olive oil to reap the benefits without increasing your overall calorie intake.
Consistency matters. Aim for 1–2 tablespoons of olive oil daily, stick to extra virgin varieties with high phenolic content, and pair this habit with regular exercise for optimal results. Adopting the Mediterranean approach - making olive oil your primary fat source - not only supports effective weight management but also promotes long-term health.
