Keeping calories under control is simple, if your first choice is shellfish (shrimp, crab, lobster, clams, mussels) at 20-30 calories per ounce. Your next choice is fish (salmon, tuna, cod, halibut, etc.) at 30-40 calories per ounce, because of the added fat calories during preparation. You next choice is poultry (chicken, turkey) at 40 calories per ounce, if you don’t eat the skin. You next choice is lean beef at 50 calories an ounce (sirlon, filet mignon), don’t eat the fat. Salt, pepper and mustard are your friends, because they are virtually calorie and sugar-free. Ketchup and cocktail sauce are not, because they contain way too many calories and way too much sugar. Soy sauce, Worcestershire sauce and Bragg’s Liquid Aminos are also essentially calorie free and high in salt, which is a good thing. The second most common side effect on low carb diets is sodium depletion. Your body automatically dumps salt when you don’t eat carbs. The most common side effect on low carb diets is dehydration, so drink your weight in ounces of water every day, or at least a gallon (128 ounces) of non-caloric fluid. If you drink below 80 ounces of non-caloric fluid a day on a low carb diet, and you can get in trouble from dehydration.
