Canola oil, derived from the seeds of a plant in the broccoli family, has a near-perfect 2.5:1 ratio of omega-6 to omega-3 fats. According to a study review published last year in Experimental Biology and Medicine, people who achieve a dietary ratio similar to this have been able to battle cancer, arthritis, and asthma more effectively. The neutral oil is also rich in alpha-linolenic acid (ALA), an essential omega-3 fatty acid that may play a role in weight maintenance, according to a recent study.
Out of all the fish in the sea, tuna is one of the highest sources of docosahexaenoic acid (DHA), an omega-3 fatty acid. Canned light tuna is one of the best and most affordable fish for weight loss, especially from your belly! One study in the Journal of Lipid Research showed that omega 3 fatty acid supplementation had the profound ability to turn off abdominal fat genes. And while you’ll find two types of fatty acids in cold water fish and fish oils—DHA and eicosapentaenoic acid (EPA)—researchers say DHA can be 40 to 70 percent more effective than EPA at regulating fat genes in the abdomen, preventing belly fat cells from expanding in size.
