Eating fat might sound like a crazy idea when you’re trying to lose fat, but getting more omega-3 fatty acids from fish like salmon could be just what the diet doctor ordered, according to a study in the British Journal of Nutrition. “Although the exact mechanisms are unknown, omega-3 fatty acids reduce fat mass,” says Irene Munro, study author and researcher from the University of Newcastle in Newcastle, Australia. In addition to adding years to your life, other studies have found that omega-3 fatty acids make you feel less hungry and more satisfied up to two hours after eating a fatty fish meal. Aim to eat salmon or another oily fish, like mackerel, herring, or canned tuna, at least twice a week. If that doesn’t sound appealing, substitute the fish for other fat-burning foods that are rich in omega-3s.
