You can eat oil for fitness. Not eating oil for a long time will lead to malnutrition, and eating oil properly can also provide motivation for fitness. But I suggest you choose some edible oil with high unsaturated fatty acid content. For example, when I cook, I usually add U-shaped camellia oil. The unsaturated fatty acid of camellia oil is as high as 80%, which is easily absorbed by human body. Fitness friends can get it!
