Sometimes overweight people, who may be pre-determined to spend their lives overweight by fate or genetics or simply because of their past habits, will spend their lives hopping from one diet to the next because they have been lead to believe that being fat is not acceptable, that they must make excuses for their weight, and they must be constantly doing something to change it. And they may be happy with themselves no matter what. And, sometimes overweight people live out their lives indifferent to what size their body is, and for the same reason. They are happy with themselves and if other people don't like it, it simply isn't their problem. These people are strong - and lucky.
Many people are constanlty insecure, unhappy, and have low self esteem.
And these people are incredibly diverse. They all look very different from one another, they are from different countries, different faiths, speak different languages. Their bodies, whether beautiful or not do not determine whether they have low self esteem or are overflowing with confidence. Their bodies do not determine if they are intelligent, or friendly, outgoing or shy. Or if they are likely to be successful, get married, be criminals, or sell cars.
