2. Sushi

On a diet, you can get away with about 6 pieces of maki with no mayo and taken with light soy sauce. Sushi is a delicious, light and wheat-free lunchtime meal, and made with tuna or salmon, it’s packed full of omega fatty acids and necessary proteins. If you’re keen on sashimi, you can pile your plate with a whole lot more since without the rice, sushi makes an even more effective slimming snack.
