Explain four challenges faced by those attempting to lose weight. what are four steps one can take to avoid obesity?

There are several challenges that a person has to face when they are trying to lose weight.

First, they need to face their health condition. They will feel so tired at the beginning, that most of the people quit almost immediately, their system is not able to perform well, their energy system doesn't function properly and it will demand too much oxygen, which the cardiorespiratory system cannot provide.

Second, the need to face a huge hunger feeling. When people try to lose weight, and they begin to exercise, their body start to demand food, and there is where they need a proper diet, because they could eat more than before.

Third, people have to face new nutritional habits. This is also a problem, because basically they don't know how to eat well, and when they do, they can't help it, because it's about too many restrictions in carbs and fats, which were part of the normal old bad nutritional habits.

Fourth, one the biggest challenges is to maintain motivated. All challenges explained before make people to feel low motivation, and they quit, thinking that the goal is to far away. So, keeping a good mind is one of the most important challenges people have to face to keep going, because it's so much harder to lose weight, than gain it.
