Obesity
Obesity is a disease in which excess body fat has accumulated to such an extent that health may be negatively affected.[1] It is commonly defined as a body mass index (weight divided by height squared) of 30 kg/m2 or higher.[1] This distinguishes it from being overweight as defined by a BMI of between 25-29.9.[1] Many studies show an association between excessive body weight and various diseases, particularly cardiovascular diseases, diabetes mellitus type 2, sleep apnea, certain types of cancer, and osteoarthritis.The two surveys also show increases in overweight among children and teens. For children aged 2–5 years, the prevalence of overweight increased from 5.0% to 13.9%; for those aged 6–11 years, prevalence increased from 6.5% to 18.8%; and for those aged 12–19 years, prevalence increased from 5.0% to 17.4%.
Genetics. A person is more likely to develop obesity if one or both parents are obese. Genetics also affect hormones involved in fat regulation. For example, one genetic cause of obesity is leptin deficiency. Leptin is a hormone produced in fat cells, and also in the placenta. Genes: Obesity tends to run in families. This is caused both by genes and by shared diet and lifestyle habits. Having obese relatives does not guarantee that you will be obese.
The goal of obesity treatment is to achieve and maintain a healthier weight. The amount of weight you need to lose to improve your health may be much less than what you feel you need to lose.Using the food diary technique you can cut out 500 calories per day from what you are eating. Keeping a diary may help to reveal particular times when you overeat, or certain types of food that you are more inclined to binge on.Try to find other activities to do rather than snacking, such as reading a magazine. Also, be careful not to buy foods that will tempt you, such as high calorie snacks, as this is an obvious way to cut out 500 calories. You should find that you are still able to enjoy a wide range of tasty options, but in moderation (restraining yourself and avoiding excess).
