Answer to Question 1

Table C8-2 lists risk factors for osteoporosis. Both smoking and low body weight are considered modifiable risk factors for osteoporosis. If she is not eating enough to maintain her weight, she is also not likely getting enough vitamins and minerals to support the health of her bones. She could also use weight-bearing exercise to keep her bones strong while avoiding gaining body fat.

Answer to Question 2

When offered a delicious smorgasbord,people overeat, often without awareness. They are responding toexternal cues. With around-the-clock access to rich, palatable foods, we eat more andmore often than in decades pastand energy intakes have risen accordingly.Overeat ing also accompanies complex human sensations such as loneliness,yearning, craving, addiction, and compulsion. Any kind of prolonged stress can alsocause overeating and weight gain. People who are overweight or obese may be especially responsive to such influences. People may also overeat in responselarge portions of food. In a classic study,moviegoers ate proportionately more popcorn from large buckets than from small bags. The effect may also generalize to children, who askedfor bigger portions of cereal when given bigger bowls than when given smaller bowls;they ate more and wasted more from bigger bowls, too.
