There is no scientific evidence to show that consuming coconut oil helps people lose weight. But there is one recent study, however, using MCT oil, which suggests coconut oil may work in the same way. Even if coconut oil does help people lose weight, few nutrition experts recommend it, since coconut oil is loaded with saturated fat: 12 grams in 1 tablespoon versus 7 grams in a tablespoon of butter.
Theoretically if you consume 500 calorie meal and replace butter with coconut oil , your metabolism will speed up and burn more like 15% or 75 calories
Not the question you should be asking, you can lose weight eating anything. However your body of course will not burn body fat while it has dietary fat to burn.
It's more about timing and quantity.
