Olive oil is not easy to gain weight in life. Although olive oil is more expensive, rapeseed oil and olive oil are basically similar in composition and are relatively healthy to eat. You can't just lose weight by eating oil that doesn't grow meat. If you want to lose weight, you should exercise more, and have a balanced diet. Don't eat too much greasy food, and it is best to give priority to light food, eat more vegetables and fruits, high-calorie and high-protein food, and don't eat it at the end during weight loss. Making a reasonable plan every day is good for losing weight.
