1. Why We Are Fat: An Evolutionary View
Our bodies have evolved very little from those of our hunter-gather ancestors, who survived by eating all they could of whatever fruits and berries were in season and whatever prey was at hand. What happens when such a creature, relieved of the need to do physical labor, is let loose in the all-you-can-eat buffet? How does an evolutionary perspective help us understand the current situation? What does it suggest about the best ways to adapt to today's environment?

2. Basic Facts about Childhood Obesity
The next generation of Americans may be the first to have a shorter lifespan than their parents, chiefly because of their growing weight and sedentary lifestyles. The statistics are frightening:

•  Fifteen percent of U.S. children ages 5 to 19 are overweight, triple the rate of 20 years ago
•  Overweight adolescents have a 70% to 80% chance of becoming overweight adults
•  The annual costs to hospitals for caring for children with obesity-related ailments were $127 million a year from 1997 to 1999, compared with only $35 million a year from 1979 to 1981—a 263% increase in 20 years

What are the implications of these trends? What can be done to reverse them?

1. How Much Exercise Do I Need?

Walk 30 minutes every day. No, walk 20 minutes every day. No, walk 30 minutes four times a week. Lift weights. Stretch. Do yoga. Pilates. Aerobics. Isometrics. Burning off calories is as effective as reducing their intake, but there are nearly as many exercise fads to choose from as there are fad diets. What does the latest research tell us about how much physical activity one needs to get healthy? To stay healthy? How do our needs change as our weight — or our age — changes?

2. The Long-Term Implications: Latest from the CDC Obesity contributes substantially to the prevalence of other chronic diseases, such as cardiovascular disease, type II diabetes, and cancer. The rapid increases in obesity have already led to increased rates of diabetes, and may shortly begin to arrest the gains achieved over the last 30 years in the reduction of cardiovascular disease. A population based approach that integrates innovative medical interventions with environmental changes in schools, worksites, and communities will be essential to reverse obesity and its associated chronic diseases.
