Some cooking oils and fats when consumed often or in large amounts increase body weight, fat accumulation, or metabolic problems. Below are six cooking oils and fats based on a study conducted by NIH associated with higher obesity and health risk potential. (Source: Photo by unsplash)

Soybean Oil: Frequent consumption of oils high in certain polyunsaturated fats like soybean oil may contribute to greater weight gain compared with other oils. Animal research suggests soybean oil diets led to more fat accumulation than other fats in comparable calorie diets. (Source: Photo by unsplash)

Butter and Margarine: Regular consumption of solid fats such as butter and margarine is associated with higher cardiometabolic risk and increased mortality which often correlates with obesity and its complications. (Source: Photo by unsplash)

Palm Oil: Palm oil is rich in saturated fats and palmitic acid. High intake of saturated fat oils such as palm oil has been linked to increased LDL (“bad”) cholesterol, and historically, saturated-fat heavy oils are associated with obesity and related metabolic problems.

Over use of Any High Calorie Oil: Even “healthy” oils contain a lot of calories. Regularly cooking or frying with large amounts of oil can lead to excessive calorie intake, which over time can contribute to weight gain, fat accumulation, and obesity, regardless of the type of oil. This is a general risk with oils and fats. (Source: Photo by unsplash)

Overuse of Refined Oil: A diet heavily based on refined oils or solid fats with minimal whole food healthy fats (nuts, seeds, fish, unprocessed oils) may shift fat balance unfavourably. Studies that compared different oils show that replacing saturated/solid fats with moderate unsaturated oils (or healthier fats) improved metabolic outcomes; implying overuse of the “wrong” oils may contribute to obesity risk.

Re-Heating or Deep Frying in Oils: Repeatedly heating oils (especially saturates or unstable oils) can produce harmful compounds and may impair metabolic health. While direct obesity data is complex, such practices are linked to inflammation and metabolic stress factors that can make weight regulation harder. (Source: Photo by unsplash)
