|Environment |
|Our environment doesn't support healthy lifestyle habits; in fact, it encourages obesity. Some reasons include: |
|Lack of neighborhood sidewalks and safe places for recreation. Not having area parks, trails, sidewalks, and affordable gyms ||makes it hard for people to be physically active. |
|Work schedules. People often say that they don't have time to be physically active because of long work hours and time spent |
|commuting. ||Oversized food portions. Americans are surrounded by huge food portions in restaurants, fast food places, gas stations, movie |
|theaters, supermarkets, and even home. Some of these meals and snacks can feed two or more people. Eating large portions means |
|too much energy IN. Over time, this will cause weight gain if it isn't balanced with physical activity. |
|Lack ofaccess to healthy foods. Some people don't live in neighborhoods that have supermarkets that sell healthy foods, such as|
|fresh fruits and vegetables. Or, for some people, these healthy foods are too costly. |
|Food advertising. Americans are surrounded by ads from food companies. Often children are the targets of advertising for |
|high-calorie,high-fat snacks and sugary drinks. The goal of these ads is to sway people to buy these high-calorie foods, and |
|often they do. |
|Genes and Family History |
|Studies ofidentical twins who have been raised apart show that genes have a strong influence on a person's weight. Overweight |
|and obesity tend to run in families. Your chances of being overweight are greater if one or both of your parents are overweight |
|or obese. |
|Your genes also mayaffect the amount of fat you store in your body and where on your body you carry the extra fat. Because |
|families also share food and physical activity habits, a link exists between genes and the environment. |
|Children adopt the habits of their parents. A child who has overweight parents who eat high-calorie foods and are inactive will |
|likely become overweighttoo. However, if the family adopts healthy food and physical activity habits, the child's chance of |
|being overweight or obese is reduced. |
|Health Conditions |
|Some hormone problems maycause overweight and obesity, such as underactive thyroid (hypothyroidism), Cushing's syndrome, and |
|polycystic ovarian syndrome (PCOS). |
|Underactive thyroid is a condition in which the thyroid gland doesn't make enough thyroid hormone. Lack of thyroid hormone will |
|slow down your metabolism andcause weight gain. You'll also feel tired and weak. |
|Cushing's syndrome is a condition in which the body's adrenal glands make too much of the hormone cortisol. Cushing's syndrome |
|also can develop if a person takes high doses of certain medicines, such as prednisone, for long periods. |
|People who have Cushing's syndrome...
