Sneak peak in Oakland of HBO "Weight of the Nation" series Wednesday

U.S. citizens stubbornly remain obese despite decades of efforts by movie stars, fitness gurus, educators and even religious leaders to get Americans into shape. Instead of becoming healthier, obesity has increased dramatically over the past 30 years, according to the Centers for Disease Control and Prevention.

The rate has tripled for children, especially among low-income youths who have few options about the quality of food they eat and the safety of the open spaces they can play in.

Now HBO is taking a shot at the obesity problem with a multipart series and public health campaign called "The Weight of the Nation."

A sneak preview will be shown Wednesday at the Oakland Museum of California.

The invitation-only event begins at 5:30 p.m. with "A Celebration of Local Food Heroes" accompanied by healthful cooking tips and free samples for attendees. "Mosswood Cookbook" author Mollie Katzen - one of the first to popularize vegetarian meals - will demonstrate techniques for meat-free menus.

At 7 p.m., the museum will show the fourth installment of the "Weight of the Nation" series, "Challenges."

Overweight and obese individuals are at increased risk for many diseases and health chronic conditions, including the following:

Hypertension (high blood pressure)
Osteoarthritis (a degeneration of cartilage and its underlying bone within a joint)
Dyslipidemia (for example, high total cholesterol or high levels of triglycerides)
Type 2 diabetes
Heart disease
Stroke
Gallbladder disease
Sleep apnea and respiratory problems
Some cancers (pancreas, kidney, prostate, endometrial, breast, and colon)

A panel of experts, including Katzen, will convene at 8 p.m. to discuss tips for healthy living and answer questions.

Katzen's fellow panelists include Anthony Iton, former director of the Alameda County Public Health Department. He now serves as an executive for the California Endowment's Healthy Communities program.

There also will be activities at a mock farmers market.

About 60 million adults, or 30% of the adult population, are now obese. • Similarly since 1980, overweight rates have doubled among children and tripled among adolescents – increasing the number of years they are exposed to the health risks of obesity.
