Think of it like this: What words come to mind when you picture a movie theater? Popcorn? That's because you've linked the movie theater with eating popcorn. Eating to satisfy hunger is an appropriate reason to eat, while eating just because you're in a movie theater (or a room in your house) is not. These habits can seriously derail your weight loss efforts.
Being the first day, it is always the hardest. Try to keep yourself away from all kinds of cravings as you will be consuming only fruits. You can consume all the fruits, excluding grapes, bananas, litchi and mangoes. You can have them in any quantity you like. It is suggested that you consume more watermelon, lime, oranges, apples, pomegranates, strawberries and melons. You can eat 20 times a day, but you should eat only fruits.
I am on day four and I am very discouraged. I don't feel as if I am losing any weight at all. I encourage you to complete the seven days. Don't be too disappointed if you don't lose all ten pounds. Everybody and metabolism is different. Do be careful, however, to follow the diet exactly. Don't eat less food than is recommended in your effort to lose weight as that will throw off the diet's chemistry.
