Why does eating lots of fish rich in omega-3 fatty acids (salmon, herring, and tuna) help amp up metabolism? Omega-3s balance blood sugar and reduce inflammation, helping to regulate metabolism. They may also reduce resistance to the hormone leptin, which researchers have linked to how fast fat is burned. A study in Obesity Research found rats that ingested large doses of fish oil while exercising lost weight. Take omega-3 fatty acid supplements; Hyman recommends 1,000 to 2,000 milligrams per day. Hate the fishy after-burp? Try flaxseed oil, walnuts, or eggs fortified with omega-3s. Or check out supplements (by brands such as Nordic Naturals) that have no fishy taste. Real Reasons Why You Can't Lose Weight After 50
Want to see those numbers on the scale get smaller? Try adding some fish to your meal plan. Research published in Obesity reveals that adding some omega-3s to subjects’ diet helped them lose more weight, keep it off longer, and limit those nagging hunger pangs. For women over 40, omega-3-rich fish, like salmon and tuna, are a particularly good choice; studies suggest that adding them to your diet may reduce your risk of hot flashes, too.
