Does oyster make you fat and how it affect your weight?

Very hight count of calories in oyster puts this product at the top of hight calorific seafood. If you are on diet and you are looking for low-calorific seafood, oyster seems to be a bad choice. It is easy to find something better among other seafood.

It is hard to find product with higher calories count in seafood. Similar energy amount have only such products as squid, shrimp or scallops.

You should consider that not only calories are important when you are on a diet. If oyster contains nutrition you need than maybe you should add it to your daily menu anyway?
