As our bodies change with age, so can our weight, either with unwanted weight gain, or unexpected weight loss. Maintaining a constant healthy weight can be challenging as we navigate new normals in our metabolism, activity levels, sleep patterns, food preferences and more.
Being overweight in older age can increase your risk for health conditions like heart disease, diabetes and stroke. There are also links between obesity and dementia. However, being underweight is not ideal either. A lower BMI can increase risk for osteoporosis and anemia, and it can be more difficult to recover from illness, according to the National Institute on Aging. It can also increase risk of fractures. Sudden unintended weight loss can be a sign of a serious medical problem.

What a healthy weight range is can be different for older adults as well. Where you are carrying your weight can be more important than what the number on the scale says, and factors such as mobility, stamina and life goals must be factored in. It’s important to talk with your doctor about your weight maintenance and lifestyle goals.
This science-based guide can help you on your healthy weight goal journey, whether you are seeking to determine the ideal weight for you, to lose a few pounds in your belly, or to add some bulk as you get older.
What is your healthy weight?
Finding a healthy weight for yourself can be complicated. Health care providers have long relied on body mass index (BMI), which is a mathematical formula in which your weight in kilograms is divided by your height in meters squared. But BMI doesn't tell the whole story. It won’t measure whether your weight is carried in your legs, hips, arms or in the more dangerous area of your belly. That knowledge is key to assessing your risk for illnesses like high blood pressure and cardiovascular disease.
To get a full picture of your weight and health, many health care providers will consider BMI along with age, body fat percentage, waist circumference and whether you have any weight-related health conditions. Age, gender, race and ethnicity can also be factors in the definition of healthy weights.
