Why Obesity is a Problem
The prevalence of obesity in the U.S. has doubled in the past two decades. Obesity raises the risk for premature death, type 2 diabetes, high blood pressure, stroke, heart disease, gall bladder disease, gout, osteoarthritis, and some types of cancers.
Causes of Weight Gain
There are many possible causes of weight gain in older adults. The major cause is being less physically active. Other possible causes are burning fewer calories with age due to a slower metabolism; having an underactive thyroid or other medical disorder; or taking medications with a side effect of promoting weight gain.
Achieving an Optimal Body Weight
Ideally, adults should achieve and maintain a body weight that is good for their health. For obese adults, even losing as little as 10 pounds provides health benefits. Reducing caloric intake by as little as 50 to 100 calories per day may help prevent weight gain. Eating 500 fewer calories per day is a common goal in weight-loss programs. Strategies to reduce calories include serving smaller portion sizes, and serving foods with fewer calories, such as low-fat foods and foods without added sugars.
Treating Obesity
Treating obesity requires the advice and supervision of a participant’s health care providers (doctor, registered dietitian, and nurse). It may involve a supervised program of diet and exercise.
