Says a 2010 study in the ‘American Journal of Clinical Nutrition’, consumption of MCT oil as part of a weight-loss plan improves weight loss compared with olive oil and can thus be successfully included in a weight-loss diet. Small changes in the quality of fat intake can therefore be useful to enhance weight loss. MCT stands for medium chain triglycerides, and occurs naturally in coconut oil. When you add MCT oils to your diet, it has a thermogenic effect – so you burn more number of calories. When you use up more calories, you store less as fat, which helps to reduce body fat levels.
