I do believe that coconut oil can help you lose weight, but it will have to be a part of a balanced diet. Poor diet together with coconut oil isn't going to help in weight loss.
You can use coconut oil easily when cooking Indian or other "exotic" food. You can also add coconut oil to your coffee or smoothie! I always add it to my morning smoothie (=banana, frozen berries and 1 tbsp coconut oil). It keeps me nice and full until lunch.
