Unlimited feeding diets don’t work – because you can’t eat as much dead animal and fat as you want, and expect to lose weight. You also can’t cheat for 1 hour a day (as is popular on some diets), and expect to lose weight. Biggest thing that doesn’t work is juicing – way too many calories, way to fast – not to mention the protein calorie deficiency you can develop. Most patients gain weight when they buy a juicer. If you eat a bag of carrots, it takes 2 hours, and you feel sick. You can drink 400 calories of carrot juice in a minute.
