Myth: A low-fat diet can help obese adults lose weight.
Truth: This is false.
While a diet high in glycemic load (refined carbohydrates and starches) could have a negative effect on carbohydrate metabolism, a high-fat diet and egg protein has been found to reverse high LDL cholesterol levels. Low-density lipoproteins (LDLs) are known as the ‘bad’ cholesterol due to their associations with obesity, metabolic syndrome, and diabetes. As such, this study has shown adults who have once consumed refined carbohydrates can actually reduce their LDL cholesterol levels through the consumption of unsaturated fats and egg protein.
Many individuals that are eager to lose weight often avoid incorporating fats into their diets. In the Journal of Nutrition, egg protein and unsaturated fatty acids replaced refined carbohydrates to see if there were changes in insulin sensitivity and triglyceride levels. The EP/UFA group showed a larger reduction in triglyceride levels and very low-density lipoprotein (VLDL) cholesterol levels. This study illustrates that a macronutrient diet that is supplemented with unsaturated fatty acids, such as avocados, and egg protein have beneficial cardiovascular health benefits.
