Animal fats and vegetable oils are fats and they all have 9 calories in every gram of oil. A tablespoon of olive oil has 13 ½ grams of fat so every tablespoon contains 120 calories. If you are overweight and trying to lose weight and you are eating olive oil then you are not going to lose weight. The olive oil myth came into being because of the Mediterranean diet.
Studies were done on obese patients living in a Mediterranean country. Their usual diet is low in carbohydrates (35%) and high in fats (43%), 55% of the latter being monounsaturated fatty acids (MUFAs), especially olive oil.
The reality is olive oil is the most calorie dense food containing 4000 calories in every pound. Olive oil has a poor ratio of omega-6 to omega-3. Accepted health goal of saturated fat is less than 7% but this oil has 14% saturated fat. There is a misconception that pouring olive oil on salad make it heart healthy. The green salads are already heart healthy without the oil. Every time you eat a fatty meal a wave of fat goes through your bloodstream. Olive oil is not friendly to the arteries. Excessive saturated fats stiffen the walls of the arteries and make them less responsive to Nitric Oxide which dilates the vessels and increases blood flow to the organs. This has been documented by Dr. Vogel,

This study investigated the postprandial effect of components of the Mediterranean diet on endothelial function, which may be an atherogenic factor.
Olive oil decreased blood flow to tissues after blood pressure cuff inflated and released.
In terms of their postprandial effect on endothelial function, the beneficial components of the Mediterranean and Lyon Diet Heart Study diets appear to be antioxidant-rich foods, including vegetables, fruits, and their derivatives…
Pouring any oil on your food is not healthy. So salad dressings without any oil are filling and healthy. You can add fruits like avocado with almonds and walnuts. Oils only provide taste, they are not health foods.
Any oil including olive oil is not good for your heart and certainly not good for your arteries.
