Some people find it hard to stick to diets and consistently fail to lose weight. They try nearly every kind of new dieting idea that comes along hoping that one of them would finally work, but the miracle never happens. Naturally, these people tend to overlook their own mistakes and fail to understand what prevents them from losing weight. The human brain displays a remarkable ability of ignoring the things it does not want to face, so it's not hard to understand why some people eat all manner of things and still claim they haven't touched anything but salad for a whole week.
Since eating and drinking are, for the most part, acts that bypass rational thinking you should try to bring them out of the twilight zone. So every time you reach out for a drink or some food, stop and ask yourself "Why am I doing this?". You may be thirsty, hungry, bored, lonely, depressed, tired or stressed, but out of this list of reasons only thirst and hunger are legitimate. Put the bottle down if you're not thirsty. Put the food back on the shelf or on the table if you're not hungry. Do you crave sweets because you're tired? Get some sleep instead. Do you feel the need to eat because you're lonely and depressed? Go to the cinema or visit a friend. Read a book, watch a movie or listen to some music. There are options.
Don't try to banish your favorite foods completely because you will only sap your own willingness to stick to a diet. The key to dieting is moderation, not denial. Do you like ice cream? Well, have a couple of spoonfuls of ice cream every Sunday. Take a break from whatever it is you're doing and enjoy this special treat. Don't feel like you're cheating on the diet and keep any guilt pangs away. You're just dieting, not preparing for admission to a convent or monastery. So have a bit of forbidden food every five days or so and enjoy the moment.
