1.5oz Grilled Salmon With Lemon & Rocket Salad = 90kcals

Oily fish like salmon contains higher amounts of fat than cod, but don't let that put you off. Omega 3 and 6 fats are essential, and are not used by the body to synthesise fat molecules. Instead, Omega fats contribute to a healthy metabolism (the rate at which your body uses energy and burns calories), a strong heart and a fully-functioning nervous system. Not bad for less than 90 calories.
