Questão de Língua Inglesa

1 As anyone who has begun an exercise program knows,
the relationships between exercise, appetite, weight control and
hunger are complex and often counterintuitive. The arithmetic
4 involved seems straightforward. You burn calories during
exercise and, over time, should drop kilos. Yet the reality is
more annoying. In both scientific studies and the world
7 inhabited by the rest of us, most people who start exercising
lose fewer pounds than would be expected.
The problem with exercise as a weight-loss strategy
10 seems to be in large part that it can make you hungry, and many
of us wind up consuming more calories after a workout than we
torched during it.
13 In any case, doctors point out that we should exercise,
whether or not the activity makes us thin. There are many other
reasons, irrespective of the effects on appetite, why exercise
16 benefits health.
