Why is it so hard for people to lose weight?

There are several reasons why people find it such a struggle to lose weight. One is the lies that make you fat. The misleading and the misinformed opinions about how to lose weight, much of which is given to us by innocent well meaning people.
The other is our subconscious need for a protection mechanism because of our fear of being vulnerable. Weight does work as a protective mechanism. For security, big bouncers are employed to ensure that there is no fighting or trouble at social functions. Even though some of those big guys couldn't fight their way out of a wet paper bag, nobody ever attempts to fight them because of their size. And rarely does anybody fight in their presence.
However our fear of vulnerability may be totally unfounded. It is wise to really deal with fear. If you are fearful, you are far more likely to attract the very thing that you fear. Often our fears are unfounded. They may just be based on something that happened in childhood when we truly were more vulnerable, yet if we were to face that same situation today, we would have the knowledge and the strength to easily deal with the situation. On the other hand if there really is a threat to personal safety, it may be far more healthy to deal with that risk rather than carrying around all that extra weight.
