It is estimated in a recent study that 42 percent of Americans are predicted to over weight or obese by 2030.

The CDC’s Weight of the Nation conference released it’s findings and will be highlighted in a four-part HBO documentary airing next week.

Cheap and easily available calorie dense food and sedentary lifestyles are largely to blame.

The stress on the health care system could be 550 billion dollars in additional medical expenditures.

Finkelstein and co-authors estimate that 11% of the population will be severely obese by 2030. Severe obesity is defined as a body mass index over 40 or being roughly 100 pounds overweight. Obese people have shorter life expectancies and greater lifetime medical costs, “suggesting that future healthcare costs may continue to increase even if obesity prevalence levels off,” wrote the authors.

“Those individuals have much greater risk of early mortality, diabetes, heart disease,” said Finkelstein. “They’re much, much more expensive and they’re on the rise, partly because 50 years ago, it was really, really hard to weigh that much. You’d have to eat all the time.”

Generic drugs are in high demand in growth markets in Europe and China and will quickly out pace the sale of name brand drugs.

One of the fastest growing markets will be for Type II diabetes medications as Western lifestyles and diseases encroach on the developing world.

Global sales growth of prescription drugs could be cut in half over the next five years as lucrative brands lose patent protection and cheaper generics and emerging markets become the only significant growth drivers, according to IMS Health.

Obesity is one of the biggest problems in this country, so people are searching for innovative ideas to attack the problem.

One possible approach is to tax sodas and other sugary drinks. It seems logical, but of course one has to deal with the food and beverage lobbyists. Also, some Americans hate the idea of the government dictating anything, though here it’s just a tax to cover the costs we as a society pay for these beverages.

A recent study, however, provides some ammunition for proponents of the soda tax.

Millions of people would lose about a pound or more a year if large taxes were tacked onto regular soda and other sugar-sweetened beverages such as sport drinks and fruit drinks, a new analysis shows.

A soda tax of 20% or 40% would generate about $1.5 billion to $2.5 billion in annual tax revenue. The 40% tax would cost the average household about $28 a year, the research shows.

“If the tax money was used to serve healthier foods in schools and build parks and recreation centers, it could lead to even more weight loss,” says the study’s lead researcher, Eric Finkelstein, a health economist and associate professor of health services at Duke-National University of Singapore Graduate Medical School.

The idea of a substantial tax on soda and other sugar-sweetened beverages has been the subject of hot debate in recent years among national, state and local policymakers. Public health advocates have been pushing for a hefty tax as a way to reduce consumption of these products to help people lose weight and become healthier.

Currently, two-thirds of people in this country are overweight or obese, which is linked to an increased risk of heart disease, diabetes, cancer and many other health problems. Obesity costs the country roughly $147 billion a year in increased medical expenses, according to another study by Finkelstein.

The soda tax seems like an obvious solution, and perhaps this study and others like it will start to tip the balance.
