The fresh oysters, shrimp kebab, boiled lobster and boiled crab are great and keep the waistline in check. At Arigato, Azuma, Kyoto and other sushi bars, order sashimi, salad and miso soup. It all conforms to the diet and is very satisfying. Coffee is good and if you must sweeten them use artificial sweeteners. There are many good bottled waters and you can find a good selection at Lazy Acres.
Trinity is particularly good.
If you get bored with bottled water then try some diet soft drinks. Diet Coke seems palatable with a squeeze of lemon of lime in it. With a little low fat cottage cheese, it is a real textural treat. Sugar-free chewing gum can help over come a craving. Many would say exercise.
