Your appetite isn’t static. Rather, it’s shaped by hormones, brain signals, and digestive processes that shift at every stage of life.
From the picky eating years of childhood to the natural appetite decline that comes with ageing, these changes can affect what you crave, how much you eat, and how your body uses the fuel it gets.
“Hunger is your body’s way of telling you it needs fuel to function and feel its best,” says Jamie Baham, RDN, a registered dietitian-nutritionist and the owner of Ladybug Nutrition in Oklahoma City, Oklahoma. By understanding the biological shifts behind these changes, you can better navigate your nutritional needs and make smarter choices at any age.
Here’s how appetite typically evolves from childhood through your golden years. Keep in mind that every person is different, so these are general patterns and may not reflect your individual experience.
In Childhood
Children are born with the ability to self-regulate their eating based on hunger cues. But psychological factors such as stress, and social factors such as a parent’s influence, also shape eating behaviour.
Growth begins to slow between ages 1 and 3, so children don’t need as many calories – and picky eating often emerges. Picky eating usually resolves by age 6, so introducing a variety of foods early can help children become more accepting of new flavours and textures.
But there’s a fine line between offering new foods and pressuring a child to eat – the latter can actually backfire, leading the child to eat less overall.
Parents can try adding healthy options alongside familiar favourites, and modeling good nutrition habits helps a lot too. Further, if a child has a negative reaction to a particular food, try experimenting with different textures or preparations.
In Teenage Years
The preteen and teenage years bring growth spurts, hormonal shifts, and developmental changes that can all affect appetite.
Puberty triggers rapid growth and development changes that increase calorie and nutrient needs, so this is when teens will require more calories than they did as children.
At the same time, changes to the brain’s prefrontal cortex (the brain region responsible for impulse control and decision-making) is still developing during adolescence, which can make teens more impulsive about food and more drawn to foods high in sugar, fat, or salt.
To help, encourage teens to tune in to their hunger cues and minimise distractions while eating. “For example, they could have a pre-portioned snack when they sit down to watch TV rather than bringing a ‘party-size’ bag to the couch,” Baham says.
Keeping protein-rich snacks on-hand and serving dinner early can also keep teens from loading up on unhealthy snacks after school.
During Your 20s and 30s
People in their twenties and thirties may experience greater career and family stress, which can affect appetite. “Stress can rewire how one relates to food,” says Nneoma Oparaji, MD, a board-certified lifestyle and obesity medicine physician based in Fulshear, Texas. “Some people lose their appetite completely while others reach for comfort food.”
“Stress often triggers cravings for high-sugar, high-fat comfort foods,” Dr. Oparaji says. And since metabolism slows during these years while food intake tends to remain the same, you may experience what’s known as the ‘middle-age spread,’ which is when an extra 10 to 25 pounds (lb) creeps in between your twenties and forties.
“Some health conditions common in your twenties or thirties can also alter appetite,” Oparaji says. These include anxiety and depression, thyroid disorders, sleep disorders, polycystic ovary syndrome (PCOS), inflammatory bowel diseases like Crohn’s and ulcerative colitis (UC), and autoimmune conditions such as coeliac disease and lupus. Pregnancy can reduce hunger and introduce aversions or increase hunger and food cravings.
If you find yourself reaching for food to manage stress, consider keeping a food diary to spot patterns between eating and mood, and explore healthier ways to de-stress, such as yoga.
If stress leaves you with no appetite, think of food as fuel and consider setting reminders to eat. “This can help ensure you’re still getting consistent nourishment, even when hunger cues so faint you can hardly hear them,” Baham says.
During Your 40s
“Our forties can be a tipping point where biological systems that regulate appetite begin to change,” Oparaji says. “Women commonly enter perimenopause where oestrogen and progesterone fluctuate, which leads to increased cravings for carbohydrates,” she says.
Meanwhile, men begin to experience a decline in testosterone, which affects metabolism and fat distribution.
“Insulin resistance, a condition in which the body’s cells don’t respond as well to insulin, making it harder to regulate blood sugar, can also emerge during this decade, further driving carbohydrate cravings and raising the risk of prediabetes and type 2 diabetes,” Oparaji says.
To help manage weight in your forties, aim for 25 daily grams (g) of fibre for women, and 38 g for men from sources like berries, whole grains and nuts to increase satiety.
Prioritising protein is also key, as muscle loss typically begins during this decade, and affects women at a faster rate than men.
During Your 50s
For women, this decade typically includes menopause or postmenopausal years. “Decreased oestrogen levels in menopause often increases carbohydrate and sweet cravings while blunting fullness cues,” Oparaji says.
These shifts make proper nutrition especially important, as it can help reduce the risk of conditions diagnosed during these years, including obesity and metabolic syndrome – a cluster of conditions that includes high blood pressure, high blood sugar, excess abdominal fat and abnormal cholesterol levels, cardiovascular diseases, and osteoporosis.
“I typically recommend that menopausal women focus on nutritious foods high in plant protein, fibre, whole grains, and healthy fats,” Oparaji says. Women in their fifties should also prioritise bone-building nutrients, such as vitamins B, C, and D, as well as calcium.
“Men may run into similar issues that were introduced in the previous decade, including a drop in testosterone and emerging insulin resistance, which can alter appetite,” Oparaji says.
During Your 60s and 70s
Appetite often decreases in your sixties and seventies, whether because of chronic conditions (such as Parkinson’s disease, heart disease and cancer), a slowing digestive system, medication side effects, and hormonal changes.
To make sure you’re still getting essential nutrients, prioritise whole foods, try eating smaller meals more frequently, and mix up your menu to keep meals interesting.
Energy expenditure also begins to decline after age 60, meaning your body needs fewer calories while nutrient needs stay the same.
And since muscle loss accelerates after age 65, increasing protein intake through diet or supplements is especially important.
The 80s and Beyond
The decrease in appetite you may have experienced in your sixties and seventies tends to become more pronounced the older you get as risk factors accumulate, including medication side effects (over 250 medications can reduce appetite), poor oral health, changes in social circumstances (such as living alone), and conditions like dementia or depression.
“It’s important for older adults and their families to stay attentive to nutrition,” Baham says, since low body mass index increases the risk of falls and early death.
“Our body needs more nutritious foods that are high in protein and fibre as this makes every bite of food truly nourish our body,” Oparaji says.
It also helps to cut down on saturated fat, added sugars, and salt; stay hydrated by drinking water at each meal; softening food textures if dental issues make chewing or swallowing difficult; and asking your doctor about supplements to fill nutritional gaps.
In addition, if you have limited mobility, consider pre-made meals from a delivery service or the supermarket to make food preparation easier. And continue following the healthy habits from earlier decades, such as aiming for three small meals and two or three snacks each day to ensure adequate nutrition even when appetite is low.
