Weight Loss in Elderly Must Be Stopped

Weight Loss in Elderly Must Be Stopped

Let’s talk about unintended weight loss in older adults. It’s a big deal. It robs older adults of their independence. It impacts their quality of life and increases the risk of death and disability. Weight loss in elderly must be stopped.

Why is Unintentional Weight Loss in Elderly Such a Big Deal?

When an older adult loses weight unintentionally, they are losing muscle. And think about what we use muscle for- everything! We need muscle to get dressed, walk, bath, cook. We need muscle to have independence. Without muscle we must rely on others to care for us.

This image is meant to represent a cross section of a leg. You can Google actual scans of a cross section of the leg- it’s quite interesting! The white dot is meant to represent the bone. The red is muscle. The cream color is body fat.

From the outside both of these legs would look the same size. But since we are looking at the inside, we see that what’s inside looks quite different. The older adult has significantly less muscle.

Now of course there are exceptions. There are older adults in excellent shape and younger adults who are bed bound and very sick. But this graphic illustrates what sarcopenia looks like on the inside.

Different ages, same weight/size, but the older adults have significantly less muscle.

What if They Are Overweight- Isn’t Weight Loss Good?

First off, losing muscle is NEVER a good thing- regardless of weight. Second, Body Mass Index (BMI) reference ranges are DIFFERENT for seniors. BMI is typically used to classify weight status. A BMI of 24.9 – 29.9 is considered overweight and a score greater than 30 and above is obese (1).

BMI and risk of Death in Adults Age 65 and OverHowever, good and solid research has shown us that BMI reference ranges are different for older adults. In fact, BMI of 24 – 30 is associated with the lowest rates of death in older adults (2). And yes, you read that right. This range is considered “overweight”. But that’s OK.

This graphic is a u-shaped curve that represents BMI and risk of death. Risk increases on both end of the spectrum (too low or too high). The lowest spot on the curve, the sweet spot, is BMI between 27.0 – 27.9. These BMI are associate with the lowest risk of death.

A BMI of up to 30.9 is still good. Even up to 33 there is still no significantly increased risk of death. And we’re in the “obese” range. But again, it’s OK. We don’t see a significantly increased risk until BMI hits 37.0 – 38.0.

However, things get a lot worse when weight decreases. A BMI of 24 is still considered good. But, a BMI or 20.0 or less is associated with a 28% higher risk of death. Yikes. Because of this, we consider a BMI <23 as underweight for older adults. Remember, BMI guidelines are different for older adults.

How Should Weight Be Addressed for Older Adults

We want to be sure we provide the very best care for older adults. So, how should weight be addressed?

  1. Consult a Registered Dietitian Nutritionist with an expertise in geriatrics.
  2. Focus on weight stability. No big GAINS. No big LOSSES.
  3. If weight loss is intended, consult a medical provider and be sure to get enough dietary protein and resistance exercise to protect muscle.

If unintended weight loss starts, make sure that high calories foods are provided to stop the loss and save muscle! You can learn more at High Calories Smoothies: Stopping Unintended Weight Loss in Older Adults and High Calorie Smoothies for Weight Gains.
