disorder
Diets Do Not Necessarily Lead to Weight Loss
- Diets work only 5 to 10% of the time.
- Most dieters regain the weight within five years.
- Dieters who regain weight often weigh more after dieting then
before.
Why Dieting Does Not Lead to Lasting Weight Loss
- Research shows that weight is to a great degree, genetically
determined
- The goal of dieting is that the body uses its stored form of
energy to make up for the energy . This works in theory but not in practice
- The body defends against weight loss both physiologically and
psychologically
- The psychologically changes the occur when food intake is
decreased include preoccupation with food and feelings of deprivation accompionied by
intense food cravings.
- The compilation of psychological changes often leads to stopping
the diet or to an overeating episode or binge. As the body has decreased energy needs at
this time, the liklihood that the dieter will gain weight is high.
- Physiological defenses against weight loss, such as a lowering of
metabolic rate a slowing of gastric motility, and fatigue are aimed at decresing the bodys
need for energy and enhancing its ability to absorb energy from food.
- Dieting can lead to weight gin do to the reduced need for energy
and increased ability to absorb energy from food.
The Problem With Frequent dieting
- Frequent dieting attempts may further complicate weight management
- Research shows that regained weight is often fat
- If the dieter is attempting to weigh a particular number, the
increase in fat stores may be at the expence of muscle tissue, which is more metabolically
active than fat tissue
- As a result the metabolic needs of the frequent dieter decreases
over time due to the numerous dieting attempts and weight cycles.
Weight Management- An Alternative To Dieting
- Adopting more effective and reasonable approaches to weight
management offers the best out look for physical and psychological health
- Learning to reduce health risk by engaging in weight management,
not dieting , seems the most approiate course of action
- According to the american Dietetic Association, "weight
management" is defined as the adoption of healthfuland substantial eating and
exercise behaviors indicated for reduced disease risk and improved feelings of energy anf
well-being"
- In simpler terms, weight management is learning to eat and
exercise reasonably
- Modest changes regaurding eating and exercise habits can result in
a small, maintainable weight change
- these changes, when maintained over years, significantly reduce
the risk of many illnesses considered to be complicated by obesidy (e.g.,
cardiovascular disease, high blood pressure, adlut onset diabetes, gastrointestinal
disease, sleep apnea)
