The calories that we consume need to
balance with the energy that we expend. If there is not a balance of calories
in matching calories out, then we either gain or lose weight. In addition to
diet, physical activity also plays a large role in weight management. “Energy
expenditure through physical activity is an important part of the energy
balance equation that determines body weight” (WHO, 2003). A cultural downfall
in American culture is the rise in value of labor-savers and ease (such as
automobiles, elevators, and get thin quick diets). We are busier than ever, but
move much less than ever before. “A decrease in energy expenditure through decreased
physical activity is likely to be one of the major factors contributing to the
global epidemic of overweight and obesity” (WHO, 2003). In addition, food is
considered a source of pleasure, not really as a source of energy. We, as a
nation, typically have grown to like rich, sugary, and high fattening foods. These
lend no nutritional value, but an abundance of unneeded calories. “Over past
decades, the abundance of food has increased enormously while the daily demand
for physical activity for survival has all but disappeared” (Sizer, 2011). This
has largely contributed to the obesity crisis that is growing in America. But,
this is not the only problem that is creeping into our society, underweight
individuals are on the rise, most likely due to the overemphasis on
unattainable images in pop culture and fashion. “Over the past
few years it has become clear that weight is an important health issue. Some
people who need to lose weight for their health don't recognize it, while
others who don't need to lose weight want to get thinner for cosmetic reasons”
(National Heart, Lung and Blood Institute, 2012). Being underweight is defined
as being below a healthy weight, typically a BMI below of 18.5. Someone may
become underweight by not consuming enough energy to make up for energy lost. Being
underweight leaves an individual with a risk of wasting (the body diminishing
in proper function), diminished immune system, and the restriction of energy
flow. Disease and malnutrition may also contribute to weight lose. Being
overweight, however, is having a body weight that is technically above a health
range (a BMI of 25-29.9). This state can occur by consuming more energy than
that which is expended. So, it is caused by both eating too much and moving too
little.
Even
being slightly overweight can negatively affect your health. It adds extra
stress to the body and its systems in which should be avoided for optimal
health. Being obese is also considered overfat, as opposed to being overweight.
Obesity is considered having a BMI 30 or higher, and increases risks for health
complications such as abdominal hernias, arthritis, kidney stones, sleeping
disorders, skin issues, varicose veins, and respiratory problems. Obesity also
contributes to various diseases, including diabetes, heart disease,
hypertension, gallbladder stones, stroke, and even some types of cancers. “Obesity
triples a person’s risk of developing diabetes, and even modest weight gain
raises the risk” (Sizer, 2011). A healthy diet alone can help diminish a
chronic disease and even reverse it. Providing the body with healthy foods supplies
it with proper energy, nourishes it, and can even heal it. As stated in
previous posts, we need a balanced variety of nutrients, and make sure that
once a healthy weight is attained we only eat the amount of energy that we need
to replace the energy we expend. Eating the right foods, coupled with exercise,
will help to maintain a proper body weight. Also, avoiding excess amounts of
refined and processed foods, while consuming proper proportions the six vital
nutrients, will additionally help maintain a healthy body weight. It is about
balance and attitude. Basically, “the best way for most people to attain a
healthy body composition boils down to control in three areas: dies, physical
activity, and behavior change” (Sizer, 2011).
