The most well established way for an overweight individual is to lose
weight is by focusing on diet and curbing the calories. As populations become more
urban and incomes rise, diets high in sugar, fat and animal products replace
more traditional diets that were high in complex carbohydrates and fibre.
Ethnic cuisine and unique traditional food habits are being replaced by
westernised fast foods, soft drinks and increased meat consumption.
Homogenisation and westernisation of the global diet has increased the energy
density and this is particularly a problem for the poor in all countries who
are at risk of both obesity and micronutrient deficiencies.
