Are People Always Completely to Blame For Their Obesity?
Is Having Negative Genetic Factors a Life Sentence of Overweight or Obesity?
What We Know: |
What We Don�t Know: |
Pharmaceutical companies are using genetic approaches (pharmacogenomics) to develop new drug strategies to
treat obesity |
Will pharmacologic approaches
benefit most people affected with obesity?� Will these drugs be accessible to
most people?� |
The tendency to store energy
in the form of fat is believed to result from thousands of years of evolution in
an environment characterized by tenuous food supplies.� In other words, those
who could store energy in times of plenty, were more likely to survive periods
of famine and to pass this tendency to their offspring.� |
How can thousands of years of
evolutionary pressure be countered?� Can specific factors in the modern
environment (other than the obvious) be identified and controlled to more
effectively counter these tendencies?� |
What It Means For You
- For people who are genetically predisposed to gain weight,
preventing obesity is the best course.� Predisposed persons may require
individualized interventions and greater support to be successful in maintaining
a healthy weight.
- Obesity
is a chronic lifelong condition that is the result of
an environment of caloric abundance and relative physical inactivity modulated
by a susceptible genotype.� For those who are predisposed, preventing weight
gain is the best course of action.
- Genes
are not destiny.� Obesity can be prevented or can be
managed in many cases with a combination of diet, physical activity, and
medication.�
- People who are affected with overweight and obesity are often victims of stigmatization and discrimination.
It is time to stop blaming the victim.� Many obesity researchers believe that people who struggle with their weight are
pushing against thousands of years of evolution that has selected for storing
energy as fat in times of plenty for use in times of scarcity.� It is time to
recognize their struggle, understand their challenges and support their need for
lifelong efforts to achieve better health.
