This is another major area of difference between the low-carb high-fat advocates and the high-carb low-fat vegans. The one thing they do agree on is that the “bad” fats include commercial hydrogenated fats (like Crisco and margarine) and trans fats that come from high-heat commercially produced vegetable oils like corn, soy, safflower, and canola oil. Some of the low-fat vegan advocates will permit a small amount of olive oil and other cold expeller-pressed oils but not coconut oil and certainly not butter! Low-carb high-fat vegetarians recommend not only olive oil but coconut oil and butter, along with avocados, olives, and nuts that are high in fat but low in carbs.
