Do Fatty Acids in Olive Oil Help With Weight Loss?

Do you ever feel hungry after eating a meal? Do you ever end up eating more after a meal because it wasn’t satiating enough? Well, there’s a simple solution to make your meals more satiating, mitigate your hunger, and manage your food intake. It’s fat – more specifically, healthy fatty acids! Fatty acids are components that have been shown to increase satiety and promote weight management. And they’re found in abundance in extra virgin olive oil (EVOO). Let’s dig deeper into what fatty acids are and how they affect weight loss.

Fatty Acids, Satiety, and Weight

EVOO is a great source of healthy fats and fatty acids. And don’t let the name “fatty acids” fool you, because many of these acids actually aid in fat loss, weight loss, and decreased hunger. These acids are created after our bodies consume, digest, and break down fats. The main types of fatty acids are saturated, polyunsaturated, and monounsaturated. In an article by Shatha Hammand and Peter Jones, they stated that “different fatty acids (FA) may vary in their obesity-inducing effect by directing the metabolism toward a pathway of either oxidation or storage...as well as by influencing satiety and appetite sensations” (2). Fatty acids have been proven to increase satiety levels or fullness, which leads to decreased appetite and food intake. These factors are significant in reducing weight and promoting weight loss. In another article by P. Casas-Agustench et. al, authors mentioned an experiment by Burton-Freeman et. al where researchers “assessed the satiating effect of three test meals containing 30% fat energy (derived from almonds, almond oil or a mixture of safflower and corn oil) in healthy subjects. Participants experienced greater satiety after almond oil (rich in MUFA and PUFA) [monounsaturated fatty acids and polyunsaturated fatty acids] and PUFA oil meals compared to the whole almond meal”(1). Based on this study, monounsaturated and polyunsaturated fatty acids have been shown to lead to greater satiation and appetite control.

Key Takeaway:

If consumed, certain Fatty Acids can increase satiety after meals, leading to Increased Weight Control.

Weight Loss Inducing Fatty Acids in Olive Oil

So, does EVOO contain the specific fatty acids that may increase satiety and promote weight loss? Well, it turns out that the fatty acids in extra virgin olive oil’s (EVOO) are very significant in increasing fullness and weight management. This is due to the fact that the majority of fatty acids in extra virgin olive oil (EVOO) are monounsaturated. According to the article by P. Casas-Agustench et. al, “although rich in fat, [nuts and olive oil] have a low content of saturated fatty acids (SFA) but a high content of unsaturated fatty acids, mainly...monounsaturated fatty acids (MUFA) in olive oil” (1). Monounsaturated fats are significant because they are one of the fatty acids that contribute the most to weight loss. According to the article by Hammand and Jones, “[t]he consumption of long-chain saturated FA (SFA) and trans-FA has been linked to obesity and specifically to abdominal fat accumulation... while unsaturated FA, polyunsaturated FA (PUFA) and monounsaturated FA (MUFA), have been found to suppress appetite as well as increase energy expenditure and fat oxidation rate, therefore, induce favorable effects on regional and total fat mass, as compared to the former two types” (2). Since monounsaturated fatty acids are the most present type of fatty acids in olive oil, they contribute to greater results in weight management. In a study mentioned in the article by P. Casas-Agustench et. al, two groups were given different meals; one group consumed high amounts of fat from dairy, while the other group consumed high amounts of walnuts and olive oil. Results of the study showed that the group that was given meals high in walnuts and olive oil showed an increase in thermogenesis (the production of heat and burning of calories). The study suggested that “[t]he fact that MUFA [monounsaturated fatty acids] and PUFA [polyunsaturated fatty acids] are more effective in stimulating PPARa [peroxisome proliferator-activated receptor-alpha, a type of protein] than SFA38 [saturated fatty acids] could explain why after consumption of walnut and olive oil-rich meals like Mediterranean Diet Snacks thermogenesis increased more than after consumption of a meal rich in dairy fat” (1). Overall, many factors of monounsaturated fatty acids, which extra virgin olive oil (EVOO) contains, lead to increased calories burned and weight lost.

Key Takeaway:

Extra virgin olive oil (EVOO) contains a high amount of monounsaturated fatty acids, which have been shown to increase thermogenesis, which helps with weight management and weight loss.
