Certain types of fish are high in omega-3 fatty acids, which promote fat loss by kicking your metabolism into high gear. The dietary action of omega-3 fatty acids is similar to that of protein – it forces your body to naturally burn more calories while helping you keep your appetite in check throughout the day. Fish is a great choice at lunchtime; the earlier in the day you eat it, the longer you will benefit from its appetite-regulating properties.
Fish also reduces your risk of heart disease, reduces cholesterol, and can help relieve arthritis and joint inflammation symptoms. A can of water-packed tuna has about 90 to 120 calories, which isn’t much considering its nutritive benefits. Salmon, mackerel and albacore tuna are all very high in omega-3 fatty acids, which may also help protect your brain and boost your cognitive capabilities. Just watch out for high mercury content; choose organic or sustainably sourced products rather than their mass-produced counterparts.
