Body Weight Set Point: When the Shoe Fits…

What does our body weight and our shoe size have in common?

The "shoe size analogy" is an illustrative concept used to help individuals understand that just as our feet have a unique, natural size, so too does our body have a weight range that is healthy and natural for us. This analogy can be especially helpful in eating disorder recovery, body image struggles, and the fight against societal pressure to conform to unrealistic beauty standards. It emphasizes that weight, like shoe size, isn’t something to be “fixed” or “changed” based on external expectations; instead, it’s something that is largely determined by our genetics and body structure.  Our bodies have a weight set point.

The Concept of a "Natural Weight Range"

Just as everyone has a different shoe size, everyone has a different weight range that is natural and healthy for their body type. Among the population, feet come in a wide range of shapes and sizes. You wouldn’t expect someone with very large feet to wear a size 5 shoe, just as you wouldn’t expect someone with very small feet to wear a size 11. Similarly, your body has a weight range that is suited to your unique biological makeup and forcing it into a weight that falls outside of that range is just as uncomfortable and harmful as trying to squeeze into a pair of shoes that are too tight. Our weight or set point is not something that can be easily manipulated.

Genetics and the "Set Point" Theory

Our natural weight range is largely influenced by genetics, just as our foot size is. “Set point theory" suggests that every person’s body has a natural weight it is inclined to maintain over time, like how your feet have a natural size. This weight range is influenced by factors like body composition, bone structure, metabolism, and genetics. Some people may naturally carry more muscle mass, while others may have a naturally higher percentage of body fat. This is perfectly normal and reflects the body’s biological diversity.

Just as trying to force your feet into shoes that are too small would be uncomfortable and unsustainable, trying to force your body to maintain a weight that falls outside its natural set point can lead to physical discomfort and long-term health problems. While people often attempt extreme diets or exercise regimens to achieve a certain body weight, the body will typically fight to maintain its natural set point. This is because the body is constantly trying to protect its internal systems, just like it protects your feet by ensuring they’re in shoes that fit.

The Risks of Trying to Achieve an "Ideal" Weight

Society often pushes the notion that there is a specific "ideal" weight or body type that everyone should aim for. This one-size-fits-all approach doesn’t reflect the reality of human diversity. Trying to fit into a body typethat is not in alignment with your natural size is not only unnatural but also detrimental to both physical and mental health.  A healthy body weight is not about meeting a societal standard or fitting into an external mold, but about what is right for your individual body. Just as you wouldn’t try to wear shoes that are too small to conform to someone else’s idea of beauty, you shouldn’t try to force your body to conform to an arbitrary weight number or body shape that isn’t right for you.

The Discomfort and Damage of Restriction

When someone restricts their food intake to lose weight or maintain a size that is not natural for their body, they are essentially doing the same thing as wearing shoes that are too tight—causing discomfort, pain, and eventual damage. In the case of weight, extreme calorie restriction can lead to malnutrition, loss of muscle mass, bone density loss, weakened immune function, and hormone imbalances. This can result in fatigue, depression, anxiety, and a range of other physical and psychological issues.

With ill-fitting shoes and with weight pushed outside its natural limits, the body is forced into a position that doesn’t suit its natural shape, causing it to resist and fight back. In anorexia recovery, for instance, part of the healing process involves accepting a weight that supports the body’s natural function and allows the person to thrive physically, mentally, and emotionally.

The Importance of Weight Restoration in Eating Disorder Recovery

The shoe size analogy is particularly useful in the context of eating disorder recovery, where weight restoration is often a central focus. For individuals with anorexia or other restrictive eating disorders, gaining weight may feel like a personal failure or a loss of control. However, achieving a healthy weight is an essential part of recovery. Full weight restoration supports physical healing, helps balance hormones, improves brain function, and allows individuals to regain energy, muscle mass, and vitality.

Just as putting on the right shoe size brings comfort and stability to your feet, reaching a healthy weight for your body can restore balance and function to your physical and emotional well-being. It allows the body to feel secure, nourished, and capable of engaging in life fully. The key point here is that achieving a weight that is naturally suited to your body is not a “defeat,” but rather a vital part of returning to a state of health and self-acceptance.

Embracing Body Diversity and Acceptance

The shoe size analogy also encourages a shift in perspective toward body acceptance. Just as we understand that feet come in all shapes and sizes, so do bodies. There is no one “right” shoe size or body size; there is only the size that fits you. Embracing the idea that your body has a natural weight range, much like your feet have a natural shoe size, helps to counteract harmful societal pressures and encourages self-acceptance.

Instead of trying to fit into a standard or a "desired" weight, the goal should be to focus on feeling healthy, strong, and comfortable in your own body, whatever that size may be. Just as wearing shoes that fit properly supports your feet and helps you walk comfortably, finding a weight that suits your body will support overall health and well-being.

Understanding and Respecting Your Body’s Needs

Weight, like shoe size, is not something that can be manipulated or controlled based on external pressures. It’s about finding a weight range that supports your individual health and well-being, just as finding the right shoe size supports your feet. Weight restoration, especially in the context of eating disorder recovery, is not about achieving a certain aesthetic or conforming to societal standards; it’s about giving your body the nourishment and support it needs to function at its best.

By shifting the focus from weight loss or body shape to self-acceptance and health, the shoe size analogy helps people embrace the idea that their body’s natural weight is something to be honored and cared for—just as we honor the natural size of our feet. Ultimately, this mindset can lead to a healthier relationship with food, body image, and overall well-being.
