"Is 'I Can't Eat as Much as I Used To' a Sign of Aging?—Reasons for Quiet Changes in Appetite and Real Voices Spreading on Social Media"

When I was younger, I could handle late-night ramen, large servings of pasta, and extra orders of grilled meat without any issues. However, since entering my 60s, I find myself feeling "that's enough" in front of my usual plate. I want to eat, but my stomach doesn't keep up. I've been leaving half of my meals at restaurants and find that two meals a day at home are sufficient.

Many people are puzzled by such changes. In a health advice article by The New York Times titled "Why Can’t I Eat as Much as I Used To?", multiple factors such as hormones, taste and smell, muscle mass, and dining environment are discussed as reasons for changes in appetite and satiety with age. In conclusion, "I can't eat as much as I used to" is not uncommon. However, whether it should simply be dismissed as "due to age" depends on the situation.

Appetite is Driven by Body Signals, Not Willpower

When it comes to appetite, it's often thought of as a matter of "wanting to eat" or "whether one can resist." However, in reality, it's a complex bodily system involving the brain, gastrointestinal tract, hormones, muscles, sensory organs, and living environment.

For example, ghrelin, known as the hunger hormone, is secreted when the stomach is empty and sends a signal to the brain to "want to eat." On the other hand, there are hormones like leptin and cholecystokinin that enhance the feeling of fullness. As we age, the secretion of these hormones and the body's sensitivity to them may change.

As a result, the amount that once felt like "I can still eat" now leads to feeling full sooner. It's easier to understand if you think of it as a change in how the hunger and fullness switches are activated, rather than a weakening of appetite.

When Muscle Mass Decreases, the Required Energy Changes

Another significant factor is the decline in muscle mass. Muscles consume energy even when at rest. If muscle mass decreases compared to when you were younger, the calories your body needs in a day also decrease.

Therefore, if someone with reduced activity and muscle mass tries to eat the same amount as when they were younger, it may be too much for their body. Conversely, there are cases where the body naturally reduces appetite to match the required amount.

On social media, there are many voices that resonate with this feeling. In Reddit communities for middle-aged and older adults, posts like "Having breakfast makes me get by with just a light snack for lunch," "Eating late-night snacks like before gives me indigestion," and "A single serving at a restaurant feels like two meals" can be found. While some express concern about decreased appetite, others take it positively, saying, "Eating less has made my body feel better," or "I've started listening to my body's signals."

When Taste and Smell Weaken, the Appeal of Meals Also Weakens

Appetite is not determined solely by nutritional needs. The aroma of freshly baked bread, the steam from miso soup, the tang of lemon, the savory scent of grilled fish—these sensations evoke the desire to eat.

However, as we age, taste and smell tend to weaken. When flavors and aromas become vague, food doesn't seem as appealing as it once did. As a result, the amount eaten decreases.

This point also garners empathy on social media. Comments like "Food doesn't taste as good as it used to," "I now prefer simple and light dishes over rich ones," and "Eating has become more about nutrition than entertainment" are common. This is not just a change in preference but a change in sensory perception that may alter one's eating habits.

It's particularly important to note that a decline in taste and smell can also occur due to illness or medication. If taste and smell don't return after COVID-19, if appetite decreases after changing medication, or if there are issues like dry mouth or difficulty chewing, it's better not to attribute it solely to aging.

"Eating Alone" Can Further Reduce the Amount Eaten

Appetite is influenced not only by internal changes but also by who you eat with.

When people eat alone, meal times tend to be shorter. Without conversation, there's less time to put down utensils, and meals are finished more quickly. Conversely, eating with family or friends extends meal times with conversation, naturally increasing the amount eaten.

As people age, factors like retirement, the death of a spouse, children becoming independent, and fewer opportunities to go out increase the time spent eating alone. This can be an unseen cause of decreased appetite and nutritional deficiencies.

On social media, caregivers express concerns like "Since my parent started living alone, they've been eating less," "Even when I bring their favorite foods, they don't eat much," and "Trying to make them eat only makes them resist." For the person themselves, it's just "not feeling hungry," but for their family, it feels like they're "suddenly weakening," which can lead to stress within the family.

Distinguishing Between "Common Occurrences" and "Dangerous Signs"

What's important here is to differentiate between natural changes due to aging and changes that require medical attention.

For example, if changes like "eating less at one time than before," "finding greasy foods heavy," or "feeling restaurant portions are large" occur gradually and there's no significant drop in weight or physical strength, there's room to adjust eating habits to fit one's lifestyle.

On the other hand, if a decrease in appetite starts suddenly, if there's unintentional weight loss, fatigue, loss of interest in previously enjoyed foods, nausea, difficulty swallowing, or persistent low mood, caution is needed. These could be signs of illness, side effects of medication, dental or oral issues, depression, dementia, or thyroid abnormalities.

In Reddit caregiving communities, posts about "elderly parents barely eating" receive responses like "It's not uncommon, but it shouldn't be left as unavoidable aging" and "You should inform a doctor." This highlights an important perspective. While decreased appetite in the elderly is common, "common" doesn't mean "no problem."

Keys to Regaining Appetite: "Exercise," "Small Portions," "Aroma," "People"

So, what can be done when you feel your appetite has decreased?

First, exercise is crucial, particularly strength training. Using muscles prompts the body to seek nutrients for repair and maintenance. Increasing muscle mass raises the required energy, making it easier to regain appetite. Exercise guidelines for the elderly recommend at least two days of muscle-strengthening activities per week. It doesn't have to be heavy barbells; light dumbbells, resistance bands, standing up from a chair, stairs, and wall push-ups are all effective.

Second, don't be too fixated on three meals a day. If having three large meals is difficult, divide them into four or five smaller ones. In older age, focusing on the total daily nutritional intake rather than the amount per meal can be helpful.

Third, pay attention to protein and nutrient density. The less you eat, the more important the nutritional value per bite becomes. Combine eggs, fish, chicken, soy products, yogurt, legumes, nuts, whole grains, vegetables, and fruits in a manageable way. For those with a small appetite, it's crucial to make meals "meaningful even in small amounts" rather than just increasing quantity.

Fourth, enhance aroma and flavor. Lemon, vinegar, ginger, garlic, shiso, green onions, herbs, spices, dashi, yuzu kosho, and shichimi can stimulate appetite even in small amounts. They also help create a sense of satisfaction without increasing salt content too much.

Fifth, reconnect meals with people. Eat at the same time as family, have lunch with friends, use community meal gatherings, or eat while on an online call. Even if not every day, creating "days to eat with someone" can impact not only nutrition but also mood.

Changes in Appetite Reflected in Social Media Reactions Are Also Changes in Lifestyle

What's striking about the social media reactions to this topic is not just the interest in health information but also how changes in appetite are discussed as changes in life perspective.

One person writes, "I feel a bit sad that I can't eat like I used to." Eating is associated with youth, freedom, family meals, travel, and the enjoyment of dining out. Therefore, a decrease in appetite brings a sense of loss beyond just a reduced stomach capacity.

Another person says, "I eat less, but I've become more selective about what I eat." This is a positive change. In the past, satisfaction came from eating until full, but now it's about savoring small amounts, not upsetting the next day's condition, and choosing what suits the body.

In posts from caregivers, more urgent voices stand out. When the person says "I don't want it," should that be respected, or should they be encouraged to prevent nutritional deficiencies? The family, worried only about the amount eaten, and the person for whom meals have become a burden—between them, the dining table can sometimes become a place of tension.

What's needed here is not to solve appetite issues with "willpower." Instead of blaming the person for not eating, explore why they don't want to eat. Is it because it doesn't taste good, is hard to chew, difficult to swallow, due to constipation, medication effects, boredom from eating alone, or depression? The solution varies entirely depending on the cause.

Future Meals Should Focus on "Design" Rather Than "Quantity"

Changes in appetite with age are not necessarily evidence of a deteriorating body but rather a sign that the body's conditions have changed. Not being able to eat as before doesn't necessarily mean you should be pessimistic. Rather, it's time to think about meals not in terms of quantity but in terms of design.

Even with small amounts, include protein. Stimulate appetite with aroma and acidity. Use muscles to remind the body that "nutrition is needed." If days of eating alone continue, plan opportunities to eat with someone. Instead of focusing on finishing a large plate, aim to maintain strength, retain enjoyment, and find a sustainable way of eating.

"I can't eat as much as I used to" is a change many people go through. However, within this change, there are important messages from the body. By not overlooking them, not being overly fearful, and observing your own appetite, meals in older age can become more peaceful and better suited to you.
