Olive Oil and Weight Regain: What Studies Show
Struggling with weight regain after losing it? Olive oil might help. Despite being calorie-dense, extra virgin olive oil (EVOO) has been linked to better weight maintenance and smaller waistlines. Studies show that consuming about two tablespoons of EVOO daily can improve insulin sensitivity, reduce inflammation, and even curb appetite. Here's a quick breakdown:
- Long-term studies: EVOO users gained less weight over decades compared to those using butter or other oils.
- Hormonal benefits: Olive oil boosts satiety hormones like GLP-1, helping you feel fuller longer.
- Metabolic effects: Improves fat burning and reduces abdominal fat storage.
- Key research: The PREDIMED study found EVOO supports weight stability better than low-fat diets.
Switching to high-quality EVOO in your meals - like drizzling it on salads or replacing butter - can be a simple, effective way to manage weight over time.

What Research Shows About Olive Oil and Weight Regain
PREDIMED Study: Olive Oil and Weight Stability
The PREDIMED trial followed 7,447 adults, aged 55–80 and at high cardiovascular risk, over a median of 4.8 years to explore how olive oil impacts weight management. Participants were divided into three groups: a Mediterranean diet enriched with extra virgin olive oil (EVOO), a Mediterranean diet with mixed nuts, and a low-fat control diet.
The findings challenged the notion that high-fat foods inherently lead to weight gain. Those in the EVOO group showed better weight stability and smaller increases in waist circumference compared to the low-fat control group. Interestingly, participants on the Mediterranean diets, including the EVOO group, lost slightly more weight overall.
"In the PREDIMED study, those exposed to MedDiet lost slightly more weight and gained less in WC [waist circumference] than subjects on control diet." - PREDIMED Study Researchers
A smaller sub-study of 187 participants revealed another layer of insight. It found that individuals with higher plasma antioxidant levels - associated with olive oil consumption - experienced an average reduction of 1.31 kg in weight gain.
These results provide long-term evidence supporting olive oil's role in promoting weight stability and maintenance.
Long-Term Studies on Olive Oil and Weight Maintenance
Additional long-term studies further highlight olive oil's role in managing weight. Data from 121,119 adults across the NHS, NHS II, and HPFS cohorts, spanning 20–24 years, revealed that adding just 7 grams of olive oil daily (about half a tablespoon) was linked to 0.09 kg less weight gain over four years. Substituting half a tablespoon of butter with olive oil daily reduced weight gain by 0.52 kg over the same period, while similar increases in butter or other vegetable oils led to weight gains of 0.37 kg and 0.16 kg, respectively.
The SUN Project, a large Mediterranean cohort study, echoed these findings. Participants who consumed the highest amounts of olive oil (median 46 g per day, roughly 3 tablespoons) gained 0.16 kg less weight compared to those with the lowest intake (median 6 g per day). Notably, higher olive oil consumption in this real-world study was not linked to an increased risk of overweight or obesity.
"Our study, carried out in a sample of free-living people, shows that a high amount of olive oil consumption is not associated with higher weight gain or a significantly higher risk of developing overweight or obesity in the context of the Mediterranean food pattern." - SUN Project Investigators

How Olive Oil Supports Weight Management
Olive oil isn't just a flavorful addition to your meals - it can also play a key role in maintaining a healthy weight. Let’s break down how this dietary staple supports weight management.
Increased Fullness and Reduced Appetite
One of olive oil's standout features is its high oleic acid content, which makes up 49% to 83% of its total fatty acids. When consumed, the small intestine converts oleic acid into a compound called oleoylethanolamide (OEA). This compound acts as a messenger, signaling to your brain that you're full and helping to naturally curb your appetite.
Olive oil also promotes the release of satiety hormones like Peptide YY (PYY) and Glucagon-like peptide-1 (GLP-1). These hormones extend the feeling of fullness after eating, making it easier to avoid overeating. Additionally, olive oil consumption is linked to higher levels of serotonin, a neurotransmitter that can further enhance feelings of satisfaction. Its monounsaturated fats also help stabilize blood sugar levels by slowing glucose absorption and improving insulin sensitivity. This prevents the blood sugar spikes and crashes that often lead to hunger and cravings.
In one clinical study involving women with excess body fat, participants who included extra virgin olive oil (EVOO) in an energy-restricted diet lost significantly more weight - about 2.4 kg (5.3 lb) - compared to those using soybean oil, who lost only 1.3 kg (2.9 lb) over nine weeks.
These appetite-suppressing effects work hand-in-hand with olive oil's metabolic benefits to help prevent fat accumulation.
Better Insulin Response and Fat Burning
Extra virgin olive oil doesn’t just help you eat less - it also supports your body in burning fat more efficiently. It improves insulin sensitivity by activating the AKT signaling pathway and increasing the expression of glucose transporter 2 (GLUT2) in the liver. This improvement in insulin response is crucial for reducing the risk of abdominal fat storage. In fact, irregular consumption of EVOO (less than six days a week) has been associated with a 5.1-fold increase in the likelihood of abdominal obesity.
Olive oil also enhances fat metabolism by up-regulating genes like PPAR-α and Cd36, which are responsible for breaking down fats to use as energy rather than storing them. It protects pancreatic β-cells, ensuring better insulin secretion when blood sugar levels rise. On top of that, the polyphenols found in high-quality EVOO combat systemic inflammation and oxidative stress - two factors that can lead to metabolic issues and weight regain.
"EVOO exerts a dual role in metabolic health, both mediating and independently enhancing the relationship between chrono-Mediterranean diet adherence and reduced abdominal obesity." - Antonio Moschetta, Department of Interdisciplinary Medicine, University of Bari "Aldo Moro"

Adding Quality Olive Oil to Your Daily Diet
Now that you know how olive oil can help with weight management, it’s time to make it a regular part of your meals. The trick isn’t just using it here and there - it’s about weaving it into your routine and picking the right kind to get the most out of it.
Choosing the Right Extra Virgin Olive Oil
Look for extra virgin olive oil (EVOO) with at least 250 mg/kg of polyphenols. These natural compounds, like hydroxytyrosol and oleocanthal, are known for their anti-inflammatory effects and their role in supporting fat metabolism.
One standout option is Big Horn Olive Oil's Ultra Premium EVOO. It’s cold-pressed within two hours and bottled fresh (within three months), which helps retain its high polyphenol levels. Research shows that consuming about 2.5 tablespoons daily for two months can significantly reduce body weight and even improve fatty liver. If you’re looking for specific varieties, Picual and Coratina are particularly rich in these beneficial compounds.
And here’s a tip: incorporating olive oil into your meals is far more effective for improving fat distribution than taking it in capsule form.
