Title: A Global Battle Against Obesity
1A Global Battle Against Obesity
- World Health Organization will decide whether to
adopt an aggressive plan outlining ways nations
can combat obesity. Suggestions include limiting
food advertising aimed at children, offering tax
breaks and subsidies to lower prices of healthful
foods, improving food labels and trying to curb
added sugars to just 10 of daily calories. The
plan also calls on food and beverage companies to
reduce the fat, salt and sugar content in their
products. - The proposal has generated intense criticism from
the U.S. government, and from the sugar industry,
grocers, soft-drink makers and big food
companies, claiming the proposal isn't supported
by science. But if the World Health Organization
approves the plan, consumers will see a
world-wide push to help them improve their diets,
including international efforts to regulate food
marketing, pricing and production.

35ADAs What to Ask
- Promise a quick fix?
- Encourage or require you to stop eating certain
foods, food groups or products? - Rely on a single study as the basis for its
recommendations? - Contradict recommendations of reputable health
organizations? - Identify good and bad foods?
- Just sound too good to be true?
36Appropriate Weight Loss Techniques
- A diet that is
- individually planned to help create a deficit of
500 to 1,000 kcal/day should be an intregal part
of any program - aimed at achieving a weight loss of 1 to 2 pounds
per week. - Physical activity should be part of a
comprehensive weight loss therapy and weight
control program because it - modestly contributes to weight loss in overweight
and obese adults - may decrease abdominal fat
- increases cardiorespiratory fitness
- may help with maintenance of weight loss.
37Appropriate Weight Loss Techniques
- Physical activity as an integral part of weight
loss therapy and weight maintenance. Initially, - moderate levels of physical activity for 30 to 45
minutes - 3 to 5 days a week, should be encouraged
- accumulate at least 30 minutes or more of
moderate-intensity physical activity on most, and
preferably all, days of the week. - Reduced calorie diet and increased physical
activity is recommended since it produces weight
loss that may result in lower abdominal fat and
increases in cardiorespiratory fitness.
