Eating fish oil and olive oil for fitness will not make you fat
Oil is an important substance for nerve conduction, cell membranes and vitamin transmission in the body. Too little oil can cause many problems such as poor mental health, autonomic nervous system disorders, etc. So don’t avoid taking oil because you are afraid of getting fat, and it will make people obese. They are trans fats (like margarine), oxidized oils (frying, deep-frying oils), etc.
If you can take in natural fish oil and olive oil, it is actually helpful to the human body.
