Obesity Weight Management

Weight Loss in Older Overweight and Obese Adults: Is It Appropriate?

Edna proudly tells you that without even trying her weight is down from 170 to 155 lbs in just three months. At age 76 and 5’ 1” tall her BMI was in the obese category, but now it’s in the overweight category—and Edna wants to lose more weight. So do you cheer her on? Or do you worry that she may experience some serious health repercussions?

More than 33% of people over age 65 are obese, so it’s likely you’ll see more people like Edna in your practice.1 Research indicates that intentional weight loss in older persons can be beneficial, especially if regular physical activity is included, but the health implications of weight loss in overweight and obese older adults is complicated.2

The “Obesity Paradox”

The Obesity Paradox describes the phenomenon that obesity appears to be protective from disease and death in some, but not all, individuals. A growing body of evidence shows that overweight and obese older adults aren’t at greater mortality risk than their normal weight counterparts.3,4 In acute and chronic heart failure, overweight and mild-to-moderate obesity is associated with improved survival.5 Moreover, obesity can appear protective among individuals with cardiovascular disease (CVD),6 and normal weight adults have higher mortality risk than obese patients with type 2 diabetes.7

In older adults, there may be other protective effects associated with being slightly overweight, such as better survival of acute illness, improved ability to handle stress, and recover more quickly from traumas.

 In some cases, maintaining an older adult’s usual body weight is more appropriate than initiating weight loss. For example, weight management in older people with CVD should aim to improve and maintain physical function and quality of life rather than prevent medical problems associated with obesity.8

There’s strong evidence that unintended weight loss leads to increased morbidity and mortality, so RDs should carefully weigh the risks vs benefits of weight loss for each individual.9 The safety of weight reduction must be the priority to avoid the potential for malnutrition and other possible complications such as bone loss, weakness, and falls.

Should Edna Lose More Weight?

Although formerly exercising daily on her stationary bike and using her resistance bands for strength training, Edna has stopped her routine due to pain from progressive arthritis. In her case, this unintended weight loss should send major red flags to you as her RD. She’s likely experiencing sarcopenia with her unintended weight loss, and this may be the beginning of a downward spiral of health issues.

You will want to ask several questions about Edna’s current eating and activity habits so you can complete an accurate nutrition assessment with appropriate nutrition diagnosis, interventions, and a monitoring/evaluation plan. A nutrition-focused physical assessment along with application of the Academy of Nutrition and Dietetics criteria may indicate that Edna has chronic disease-related malnutrition. Her unintended weight loss may have led to muscle weakness, which in turn may lead to decreased abilities to perform daily activities (such as shopping and cooking), falls, and other health problems.

As you assess Edna or any of your obese older patients, many questions must be answered before determining whether weight loss is appropriate: Will weight loss reduce risk factors for other complications? Will weight loss prolong life for the individual? What are the risks associated with obesity treatment? Will a diet that restricts calories reduce the individual’s ability to consume adequate nutrients to maintain health?10 Only after answering these questions can RDs determine the best approaches for clients.

  1. Thank you for this advice. I have believed this and after many years of practice agree that weight loss diets are not the answer for our elderly. Good food choices and a healthful diet are the key!

  2. I appreciate the advice given on weight loss in the elderly. There has been so much publicity about the obesity epidemic that some dietitians forget that weight loss isn’t necessarily a good thing in the aged. This article presents a thoughtful and careful approach to weight management in older adults.
