The United States is one of the world's fattest nations, but other countries are catching up. We'll go to South Africa, where diabetes is on the rise. We'll also learn about efforts to improve diet and fitness in Finland and Singapore. And we'll hear how the size acceptance movement is going global.

OBESITY IN THE DEVELOPING WORLD

Obesity is going global. Girths are spreading everywhere, no longer only in rich countries. In the developing world, a history of malnourishment puts many people at greater risk of dying from the diseases of obesity. The World's Patrick Cox reports from South Africa.

CHANGING PEOPLE'S EATING HABITS

No country has successfully reduced its adult obesity rate. But epidemiologists point to Finland as an example of what to do. In the 1970s, Finns were dying from heart disease in record numbers. Authorities reduced the incidence of heart disease by changing the national diet. The World's Patrick Cox reports from Finland.

STIGMATIZING THE OBESE

We continue our special program on global obesity, In Singapore, authorities have reduced the child obesity rate with a school program that separates out fat kids. The World's Patrick Cox reports from Singapore.

SIZE ACCEPTANCE IN FRANCE

The size acceptance movement began in the United States, but in recent years it has spread to many other countries. In France, "plus-size" models now regularly walk the runways. The World's Patrick Cox reports from Paris.

THE PHARMACEUTICAL OPTION

Just about every major pharmaceutical company is developing one or more anti-obesity drugs. The drugs are more powerful than their predecessors, but there are also more side effects. Analysts predict a multi-billion dollar future for the successful drugs. And many overweight people in the United States and abroad say they'll accept the risks of serious side effects. The World's Patrick Cox reports.
