If you need a quick fix but also something tasty and you find pizza as a very pleasing convenience, try a thin-crust at Domino's with ham and pineapple instead of pepperoni. That will be around 200 calories you'll have just saved from entering your body.
One must also not disregard the joy of quenching thirst with a massively-calorie-ridden milkshake! It tastes amazingly good but thankfully they are offered at different sizes which means despite the fact that you can still enjoy your favorite milkshake, you can also go for a smaller sized cup. For example, a triple-thick strawberry shake at the king size goes for over 1000 calories! A small-size goes for 420 calories. If you need your shake, go for the small size. If you want to trim your waistline then discard the shake and order an orange juice!
