Almost every low carb diet book tells you that you can eat as much protein (and some say protein and fat) as you want.. Don’t believe it for a second. You cannot eat 1-2 whole chickens a day, with skin or without, and expect to lose weight. You can’t start your day with a dozen eggs in butter, and expect to lose weight. You can’t eat a 2 pound ribeye steak, and expect to lose weight. You’ve got to learn how to count protein calories, if you want to lose weight and not just spin your wheels. The good news is that dead animal calories are easy to count. In general, fish and shellfish is 20 calories an ounce. Chicken is 30 calories an ounce. Pork is 40 calories an ounce. Filet mignon or sirloin is 50 calories an ounce. A 4 ounce portion of dead animule is about the size of a deck of card or the size of a fast food burger. There’s a reason McDonald’s calls them quarter pounders.
