6Overweight vs Obesity Perceptions vs Reality
- While theres no disputing the growth in the
populations girth, what people perceive in terms
of their own weight and health is a long way from
whats really going on. A new survey commissioned
by the National Consumer League of US adults
highlights the disconnect - 12 view themselves as obese while self-reported
height/weight measures indicate 34 (since
individuals tend to underreport weight, the
number is likely higher) - Of those who view themselves as just overweight,
82 are in fact obese. The discrepancy between
perceived and actual overweight-ness isnt
surprising when you consider the social stigma
associated with the term obesity

calories to lose 12 pounds per week. - Reduce dietary fat intake to less than 30 of

16Eat on the Defensive
- Do nothing else while eating just enjoy your
food. If you habitually watch TV while you eat,
you might be tempted to eat each time you turn on
the TV. - Stop eating when you are full. When you eat out,
you dont have to try to get your moneys worth
just because you are eating out. Take some home
in a doggy bag. - Dont eat everything on your plate (even though
your mother told you to). The last thing most of
us need is to load a plate with food and eat
everything on it.
17Eat on the Defensive
- When eating out, chose smaller portions or share
your meal with someone. A couple of appetizers
are just about as much food as an entrée. - Dont bring problem foods home. Out of sight, out
of mind. - You dont have to have dessert at every meal. If
you do need a dessert, have a small serving or
some fruit. - When you are done eating dinner, remove the
serving dishes from the table so you arent
tempted to keep eating.

consider when you try to adopt a healthy diet. - The trick is to find the healthy foods you like
and make them a regular part of your diet.

purchase food was spent on ready-to-eat foods
away from home. - Most fruits are also foods of convenience, but
they are not as highly promoted.

individuals) would be healthier with a lower BMI. - But many people with a BMI of 23-25 are not at
their healthiest weight. - The risk of heart disease, diabetes, and high
blood pressure begins to climb at BMIs of 22 or

source, and save your glycogen for the big hills. - a. During aerobic activities, keep your Heart
