what to eat the first week of atkins diet
Tuna, flounder, herring, sardines, cod and halibut are additional types of fish you can eat during the first week of the Atkins Diet. Shellfish, such as clams, crab, squid, lobster and shrimp, are also permitted during the first week of the Atkins Diet. Oysters and mussels are also allowed, though they contain more carbs than other shellfish, so you're encouraged to eat 4 ounces or less each day, according to the Atkins website.
