This "Healthy" Fat May Secretly Be Fueling ObesityScienceDaily · June 11, 2025 Olive oil's main fat may secretly drive obesity by creating more fat-storing cells. Credit: Shutterstock Eating a high-fat diet containing a large amount of oleic acid - a type of fatty acid commonly found in olive oil - could drive obesity more than other types of dietary fats, according to a study published in the journal Cell Reports. The study found that oleic acid, a monounsaturated fat associated with obesity, causes the body to make more fat cells. By boosting a signaling protein called AKT2 and reducing the activity of a regulating protein called LXR, high levels of oleic acid resulted in faster growth of the precursor cells that form new fat cells. "We know that the types of fat that people eat have changed during the obesity epidemic. We wanted to know whether simply overeating a diet rich in fat causes obesity, or whether the composition of these fatty acids that make up the oils in the diet is important. Do specific fat molecules trigger responses in the cells?" said Michael Rudolph, Ph.D., assistant professor of biochemistry and physiology at the University of Oklahoma College of Medicine and member of OU Health Harold Hamm Diabetes Center. Rudolph and his team, including Matthew Rodeheffer, Ph.D., of Yale University School of Medicine and other collaborators at Yale and New York University School of Medicine, fed mice a variety of specialized diets enriched in specific individual fatty acids, including those found in coconut oil, peanut oil, milk, lard and soybean oil. Oleic acid was the only one that caused the precursor cells that give rise to fat cells to proliferate more than other fatty acids. "You can think of the fat cells as an army," Rudolph said. "When you give oleic acid, it initially increases the number of 'fat cell soldiers' in the army, which creates a larger capacity to store excess dietary nutrients. Over time, if the excess nutrients overtake the number of fat cells, obesity can occur, which can then lead to cardiovascular disease or diabetes if not controlled." Unfortunately, it's not quite so easy to isolate different fatty acids in a human diet. People generally consume a complex mixture if they have cream in their coffee, a salad for lunch and meat and pasta for dinner. However, Rudolph said, there are increasing levels of oleic acid in the food supply, particularly when access to food variety is limited and fast food is an affordable option. "I think the take-home message is moderation and to consume fats from a variety of different sources," he said. "Relatively balanced levels of oleic acid seem to be beneficial, but higher and prolonged levels may be detrimental. If someone is at risk for heart disease, high levels of oleic acid may not be a good idea." ARTICLE SOURCE: https://www.sciencedaily.com/releases/2025/06/250611084111.htm

SUMMARY:
In this blog post, Douglas Schorr, a 75-year-old carnivore diet advocate, shares his journey from obesity to health, attributing his transformation to a near-exclusive meat-based diet. He recounts gaining significant weight (120 kg) during his Rhodesian National Service in the 1970s due to inactivity and a sugar-heavy diet. Three years ago, Schorr adopted a carnivore diet, dropping to 97 kg and stabilizing at 102–104 kg with added muscle. He claims this diet eliminated his sugar cravings and restored his strength and agility.
Schorr argues that obesity, affecting 42% of Americans and rising globally, is not primarily genetic but a result of modern diets high in sugar and refined carbohydrates. He likens these foods to addictive substances, citing their impact on dopamine pathways and the food industry’s role in engineering addictive products. He dismisses the calorie-centric view, emphasizing hormonal responses—insulin surges from carbs lead to fat storage.
He critiques the "Big 5 Profit Maximisers" (religion, government, food industry, pharma, and medicine) for promoting the Standard American Diet (SAD), which prioritizes carbs and sugars, fueling a cycle of obesity, diabetes, and profit. Schorr highlights the high cost of diabetes care ($237 billion annually in the U.S.) and the societal toll, including childhood obesity and diminished potential. He contrasts the slow digestion of meat (14–17 hours) with fast-digesting carbs, which leave people hungry and prone to overeating. A meat-based diet, he argues, aligns with human biology, restoring satiety and health.
The post frames obesity as a manufactured crisis, preventable through dietary change, and a rejection of the profit-driven food system.
