If you hate fish, substitute hots dogs or hamburgers on the Cat Food Diet. Go as long as you can without eating. When you can’t stand it any more, eat 2 hot dogs. No bun. The only thing you can put on your hot dogs is yellow mustard. Go as long as you can without eating again. When you can’t stand it any more, eat 2 more hot dogs. Repeat the process. Most patients eat 4-6 hot dogs a day. Make sure you drink at least a gallon of non-caloric fluid every day and drink 2-4 bouillon cubes in water. After at least 2 days on hot dogs, switch to hamburgers – no bun, same drill. Keep drinking your fluid and bouillon. You’ll lose 5-10 pounds a week.
