What is the difference between being "curvy" and being "overweight'?

Fatness is seen in some cultures as a sign of health. Especially, in these places where many people don't have many to eat. I remember once when I saw a docummentary. I think it was located in Africa. The thing is the fatter the woman was, the more attractive she was considered by men.

Now, in our society, is viewed just the opposite.

Conclusion: How imbalance this world is. Half world dying for food and the other half on diets.
