“…adding 1 oz of a sugar-sweetened beverage and
walking 1 minute less per day creates a temporary
energy surplus of about 13 kcal/d, leading to a
weight gain of 0.6 kg (1.4 lb). Repeating changes
in diet and physical activity of this magnitude on an
annual basis for 28 years would produce the 370
kcal/d “energy gap” and 16-kg (35-lb) weight gain.”

Bariatric surgery makes people live longer
• 24% reduction in mortality (N Engl J Med 2007)
• 53% reduction in fatal heart attacks (JAMA 2012)

But…
• Increased suicidality (Am J Med 2010)• Possibly increased alcohol abuse (JAMA 2012)• Decreased bone mineral density (BMJ 2012)• Postoperative care is complicated
Hospitalizations roughly doubled (7.9% vs 3.9%) over six years (JAMA 2012)

It’s not like we’re not trying…
40 percent of obese Americans say they’ve lost >5% of their weight in the last year
Most successful weight losers 1) exercised more, 2) intentionally ate fewer calories, and 3) used prescription diet medications
Those who lost the most joined a formal weight-loss program
People who tried to lose weight by eating diet foods and products were the most likely to gain weight
American Journal of Preventive Medicine 2012

Children are less active today than at any other time in American history, spending 7.5 hours a day watching TV, playing video games or simply involved in efforts that don't require movement

“…27% to 30% of the daily caloric intake of American children and adults is comprised of low nutrient density food
“…with sweeteners and desserts contributing 18% to 24% of the total”
