Causes of Obesity
Obesity is usually caused by lifestyle. People generally consume too much food and expend too little energy. The only way to gain weight is to consume more calories than you burn. What causes people to do this, however, is caused by different things and varies from person to person. Genetic, environmental and psychological factors contribute.
Genes don't definitively cast someone to a lifetime of obesity. Lifestyle plays a huge factor. Americans have high-fat diets consisting of processed, high-calorie, fast food, with a lack of physical activity.
Sometimes, all people have to do to lose weight is cut out fast food or excercise.
Obesity usually runs in families. Despite the fact that families share the same diets and children learn, studies show that obesity is still highly related to genetics.
Studies show that adults adobpted as children had weights closer to their biological parents than their adoptive parents.
Many people overeat because of boredom, sadness or frustration.
Most overweight people have no more psychological problems than people of average; however, their coping mechanism often revolves around binge eating.
People with the most severe binge eating problems usually have depression and low self-esteem.
Obesity Causing Diseases
Many people believe that all people can control their weight, which in fact is not true. Many totally separate diseases can cause obesity.
- Hypothyroidism - The thyroid doesn't produce enough hormones. The body uses energy (food) much more slowly than in other people.
- Cushing's syndrome - The adrenal glands excrete too much cortisol. One of cortisol's tasts is balancing the effects of insulin and regulating the metabolism of proteins, and carbohydrates and fats. When there is such an imbalance, these tasks don't occur properly.
- Prader-Willi syndrome - A chromosomal abnormality. Individuals with this disorder have a disordered appetite/satiety function. No matter how much they eat, they never feel full and always feel hungry. The urge to eat is incredible. Eating is not a choice, biologically
- Hypoglycemia - The sugar producing mechanism doesn't work properly. People continuously eat to keep a steady flow of sugar going through their blood and avoid going into a hypoglycemic attack.
