Does Weight Loss Get Harder With Age?

Written by Andrew Le, MD

UpdatedMarch 4, 2024

As we grow older, losing weight can become more difficult due to our metabolism slowing down naturally. Researchers and health enthusiasts have conducted many studies to understand the connection between age and weight loss.

One study in the Journal of the American Medical Association discovered that after age 25, metabolism decreases by about 2-4% per decade. This decline in metabolism can make it challenging to maintain a healthy weight as we age.

Still, with the right strategies and lifestyle adjustments, overcoming these obstacles and achieving successful weight loss is possible.

In this article, you'll discover why weight loss becomes more challenging as you age and explore lifestyle changes that can assist older adults in shedding those extra pounds.

🔑 Key Takeaways

  • Your Basal Metabolic Rate (BMR) decreases as you age, making it harder to burn calories at rest. Loss of muscle mass, known as sarcopenia, further reduces your metabolic rate, making weight loss more challenging.
  • Changes in growth hormones, sex hormones, thyroid hormones, estrogen, and cortisol can affect metabolism and fat distribution, making weight management more complex as you age.
  • Declining physical activity, often due to mobility issues, chronic conditions, or lifestyle changes, can lead to muscle loss and a decreased metabolic rate, making weight loss harder.
  • Chronic conditions can impact appetite, metabolism, and energy expenditure, affecting weight management. Conditions like gastrointestinal disorders, cancer, and neurological issues may lead to unintended weight changes.
  • Social isolation, emotional eating, financial constraints, cultural norms, depression, and anxiety can influence eating behaviors and contribute to weight gain or loss in older adults.
  • Medications commonly used by older adults can have side effects that affect appetite, metabolism, and weight, making weight loss more challenging.

Why Does Weight Loss Get Harder As You Age?

As you enter your 30s, your body typically requires less energy, which means you may not be able to eat as much as you did in your 20s. As you reach middle age (around 40 and beyond), changes in muscle composition, hormonal fluctuations, and metabolic adjustments collectively pose greater challenges to maintaining a healthy weight.

Here are the factors contributing to harder weight loss as you age:

1. Metabolic Changes

Weight loss can be challenging due to various metabolic changes accompanying the aging process. These changes include:

  • Basal Metabolic Rate (BMR) Decrease: BMR, which measures the energy expended by the body at rest to maintain essential physiological functions, tends to decrease with age. This is partly due to a decrease in muscle mass and a decrease in the efficiency of cellular processes.
  • Loss of Muscle Mass (Sarcopenia): Aging is associated with a gradual loss of muscle mass, occurring at a rate of 3-8% per decade. Since muscles burn more calories than fat, reduced muscle mass can contribute to a decrease in metabolic rate, making weight loss more difficult.

2. Hormonal Changes

Hormonal changes accompanying the aging process can significantly impact body composition and metabolism, posing additional challenges to weight loss. Key hormonal changes include:

  • Growth Hormones: These hormones regulate metabolism, muscle maintenance, and fat utilization. As their levels diminish with age, the body's ability to efficiently burn calories and maintain muscle mass is compromised.
  • Sex Hormones: Hormones like estrogen and testosterone play a role in influencing body composition and the distribution of fat. Changes in these hormone levels can increase fat tissue accumulation, especially in the abdominal area.
  • Thyroid Hormones: Thyroid hormones influence metabolic rate, affecting calorie-burning efficiency. Imbalances in thyroid hormones can contribute to weight gain or difficulty losing weight.
  • Estrogen: Low levels of estrogen, typically seen with aging, perimenopause, and menopause, may affect body weight and body fat distribution, often leading to central obesity, an accumulation of weight around the body's trunk.
  • Cortisol: Cortisol, the stress hormone, can influence weight gain or loss. Chronic stress and high cortisol levels can boost appetite, unhealthy food cravings, and abdominal fat.

3. Reduced Physical Activity

Creating a calorie deficit necessary for effective weight loss becomes more challenging when fewer calories are burned through movement. Reduced physical activity can contribute to muscle loss and decrease overall metabolic rate, making weight loss more demanding. This decline in physical activity may result from various factors:

  • Decreased Mobility: Older adults may experience limitations in mobility due to age-related changes, chronic conditions, or joint discomfort, which can reduce overall physical activity.
  • Chronic Conditions: Chronic health conditions, such as arthritis, cardiovascular issues, or respiratory problems, can impact an individual's ability to engage in regular physical activity. These conditions may necessitate lifestyle adjustments and limit the range of activities an older adult can participate in.
  • Lifestyle Changes: People's priorities and daily routines may evolve as they age. Retirement, changes in daily responsibilities, and shifts in social interactions can influence the amount of physical activity incorporated into daily life, sometimes leading to decreased physical movement and calorie expenditure.

4. Chronic Health Conditions

Chronic health conditions can influence weight management in the following ways:

Appetite Changes

Chronic health conditions can impact appetite and result in unintentional weight loss or gain. Among the chronic health conditions that can cause these effects are:

These conditions can lead to changes in appetite. Some conditions may cause a loss of appetite, leading to unintended weight loss, while others might result in increased appetite or altered taste preferences, contributing to weight gain. Appetite changes can disrupt the balance of calorie intake and expenditure, making it challenging to maintain a healthy weight.

Metabolic Effects

Chronic health conditions can impact the body's metabolism. For instance, conditions like thyroid disorders or hormonal imbalances can affect the rate at which the body burns calories, leading to variations in energy expenditure and potentially resulting in weight gain or loss.

5. Psychosocial Factors

Psychosocial factors can influence weight management in the following ways:

  • Social Isolation: Individuals may be more inclined to eat emotionally or out of boredom when socially isolated. Moreover, reduced social interactions can lead to fewer opportunities for engaging in group activities or exercise, contributing to a more sedentary lifestyle.
  • Emotional Eating: Emotional factors such as stress, anxiety, and loneliness can lead to emotional eating, characterized by consuming calorie-dense comfort foods to cope with negative emotions. This habit can result in weight gain over time.
  • Financial Constraints: Limited finances can lead to compromises in food choices. Healthy foods may seem expensive, pushing individuals toward cheaper, calorie-dense options. This can encourage diets rich in processed foods and lacking in nutrients, complicating weight management.
  • Cultural and Social Norms: Cultural norms, family traditions, and societal expectations influence eating habits. Special occasions and gatherings often feature calorie-rich foods, making weight management more challenging.
  • Depression and Anxiety: Conditions like depression and anxiety can impact appetite and motivation. Some may experience weight loss due to reduced appetite, while others may turn to food for comfort, causing weight gain.
  • Body Image and Self-Esteem: Body image concerns and low self-esteem impact eating behaviors. Some resort to restrictive eating or extreme diets to achieve a desired body size, while others may experience emotional distress due to body dissatisfaction.

6. Medication Side Effects

Weight loss can be challenging for older adults who frequently take multiple medications, as the side effects may complicate their efforts. Some medications can impact appetite, metabolism, or weight, making it harder to achieve desired weight goals.

What Are Some Lifestyle Changes That Can Help Older Adults Lose Weight?

Lifestyle changes can significantly prevent or manage common chronic conditions in older adults, such as diabetes, high blood pressure, and heart disease. These changes can also contribute to healthier living.

Here are some lifestyle changes that can help older adults lose weight:

  • Balanced Diet: Prioritize a well-rounded diet that includes a variety of nutrient-rich foods. Emphasize lean proteins, whole grains, fruits, vegetables, and healthy fats while limiting processed foods, sugary snacks, and high-calorie beverages.
  • Portion Control: Practice portion control to avoid overeating. Smaller plates and bowls can help with portion control and prevent mindless eating.
  • Mindful Eating: Eat slowly and mindfully, focusing on hunger and fullness cues. This can prevent overeating and promote better digestion.
  • Stay Hydrated: Drink plenty of water throughout the day to avoid mistaking thirst for hunger.
  • Regular Exercise: Include regular aerobic exercises like walking, swimming, cycling, and strength training. Consult a fitness professional to create a safe and effective exercise plan.
  • Strength Training: Strength training can build muscle mass, enhancing metabolism and body composition. Include resistance exercises using body weight, resistance bands, or weights.
  • Flexibility and Balance: Activities like yoga and tai chi can improve flexibility, balance, and coordination, which become increasingly important with age.
  • Consistency: Establish a consistent exercise routine and make it a part of your daily or weekly schedule. Consistency is crucial for achieving and sustaining weight loss.
  • Sleep Quality: Prioritize getting sufficient, high-quality sleep, as poor sleep can impact metabolism and make weight loss more challenging.
  • Stress Management: Incorporate stress-reduction methods such as deep breathing, meditation, or engaging in enjoyable hobbies. Chronic stress can contribute to weight gain.
  • Consult a Professional: Before making major diet or exercise changes, especially if you have underlying health issues or take medications, consult your healthcare provider. They can provide customized advice tailored to your medical history.


Losing weight is a journey that demands patience, unwavering dedication, and a well-rounded approach. Prioritizing your overall health and wellness should take precedence over fixating solely on the numbers on the scale.


Losing weight can become more challenging as you age due to metabolic changes, muscle loss, and various psychosocial factors. Your body's resting energy expenditure decreases, which means you burn fewer calories at rest, and the loss of muscle mass further diminishes your calorie expenditure.

Hormonal changes can result in increased fat storage, while reduced physical activity and chronic health conditions can hinder your efforts to manage your weight as you age.

However, there are ways to overcome these challenges. Prioritizing a balanced diet, engaging in regular physical activity, and addressing emotional and social factors related to eating can all help you achieve healthier and sustainable weight loss.
