While there is some research to suggest that coconut oil can reduces waist size, as of 2015 there is not enough evidence to suggest that people who eat it experience significant weight loss, notes Mayo Clinic. Healthy eating and exercise are the best ways to lose weight.
Though people who eat small amounts of coconut oil will not harm themselves, there is no medical evidence they lose weight, states Mayo Clinic. Coconut oil is high in calories and has more saturated fat than lard, and there isn't enough research to make a connection between coconut oil use and heart health. While the body may not convert coconut oil directly to fat, the high calories it provides may lead the body to convert other foods to fat.
