Protecting Your Cognitive Health: Understanding the Hidden Impacts of Eating Disorders

When we think of eating disorders, we tend to think of physical symptoms—restrictive eating, for example, or rapid weight loss. These symptoms are often indicators of a deeper problem and can be incredibly disruptive to our day-to-day functioning.

But we can also experience mental and cognitive symptoms that fly under the radar at first. The connection between what we eat–or don’t eat–and how our brains function is well-documented.¹

Yet we often overlook the impact of eating disorders on mental health and cognitive function.

The Impact of Eating Disorders on Mental Health

High-performing professionals and athletes, who must rely on a clear mind, are particularly vulnerable to the cognitive decline that can result from disordered eating… It can lead to significant setbacks in career and performance.

So how does this happen?

Eating disorders can lead to malnutrition,² and when the body is deprived of essential nutrients, the brain cannot operate at full capacity. The nutrient deficiencies impair several cognitive processes, like memory, concentration, and decision making.

Obviously, these are all critical functions for high-performing people.

Think about memory, for example, one of the first cognitive functions to be impacted by malnutrition. Someone with an eating disorder may have difficulty recalling information, forget important tasks, or struggle to retain new knowledge. They may have trouble with concentration, struggling to stay focused during important tasks or maintaining mental clarity in high-pressure situations.

Decision-making, a key skill for high-performing people, can be compromised–since both memory and concentration are critical components–leading to poor choices and an increased risk of errors in judgment.

The impact of these cognitive impairments isn’t limited to individual performance, either. In team settings, the inability to focus, remember details, or make sound decisions can disrupt group dynamics and result in setbacks for everyone involved.

Eating disorders are dangerous for many reasons, and when they impair cognitive ability, the consequences can be severe–and long-lasting, if not treated properly.³ It’s crucial for high-achievers to understand the toll an eating disorder can take in order to preserve both mental health and long-term performance.

Recognizing the Signs of An Eating Disorder on Mental Health

Recognizing an eating disorder begins with identifying key behaviors that often go unnoticed in high-performing individuals–like restrictive eating, excessive exercise, overzealous calorie counting, or purging, for example.

These actions aren’t simply about controlling food intake. They reflect a deeper struggle that can lead to significant physical, mental, and social changes.

If you or a loved one is struggling with an eating disorder that’s impacting mental health and cognitive function, signs and symptoms may include:

Weight fluctuations: Rapid weight loss, often explained away as working toward fitness or health goals;

Chronic fatigue: Persistent tiredness from malnutrition, even with sufficient rest;

Social withdrawal: Avoiding social interactions, particularly those involving food, or becoming more isolated in general;

Irritability: Increased mood swings or crankiness, especially related to eating or exercise routines;

Mental fog: Difficulty concentrating, remembering details, or staying focused on tasks; or

Heightened anxiety or depression: Worsening mental health symptoms, often linked to food, body images, or performance pressures.

These behaviors and warning signs are often rationalized by high performers as mere stress or burnout. After all, professional aspirations tend to be elevated for high-achieving people already, and they often don’t follow average patterns.

Red flags can go unrecognized or even become normalized as the “cost” of success. But early recognition and intervention are crucial to preventing long-term harm and sustaining mental and physical well-being.

Strategies for Addressing the Impact of Eating Disorders on Mental Health and Cognitive Impairment

Addressing the cognitive and mental health impacts of eating disorders requires a comprehensive, evidence-based approach that targets both mind and body. High-performing professionals and athletes have to prioritize both mental and physical health to maintain peak performance and overall well-being.

Seek Professional Help
First, let’s be very clear: eating disorders are serious things that cannot and should not be taken lightly. So the first and most important step to addressing them is to consult with a healthcare professional who specializes in eating disorders. This might be a clinical psychologist, a nutritionist, or a psychiatrist who can provide an accurate diagnosis and create an appropriate, tailored treatment plan.

Early intervention is critical. By addressing an eating disorder head-on, you can prevent further harm–including mental health impacts and cognitive issues–and begin the process of recovery.

Restore Nutritional Balance
Alongside mental health treatment, restoring proper nutrition will be essential to reversing cognitive impairments. Malnutrition deprives the brain of the energy it needs to function optimally. You’ll need a balanced eating plan that provides the necessary nutrients for cognitive recovery.

A nutritionist or other professional will help you focus on:

Regular, balanced meals: Ensure that each meal contains a mix of macronutrients (carbs, proteins, and fats) and micronutrients (vitamins and minerals);

A consistent eating schedule: Avoid long gaps between meals to maintain stable blood sugar levels, which will help with cognitive function; and

Hydration: The ultimate “adult drink,” after all! Adequate water intake is essential for mental clarity and overall health.

Nutritional recovery is a gradual process, but with consistency and guidance from an experienced professional, you can rebuild cognitive function and improve your overall wellbeing.

Incorporate Mindfulness Practices
Mindfulness practices like meditation and deep breathing can be beneficial exercises for any high-performer–but they can be especially helpful in reducing the stress and anxiety that often go hand-in-hand with eating disorders.⁴

Regular mindfulness practice has been shown to improve focus, reduce mental fog, and support overall cognitive health.⁵ Ultimately, these practices promote mental clarity and emotional regulation, making it easier to manage the kind of dysregulated thoughts and behaviors that underlie eating disorders.

Consider integrating mindfulness into your daily routine, even if only for a few minutes each day.

Build a Support System
Our mental health can always benefit from a strong support system, and recovery isn’t a journey you should try to take alone. Building a social network that includes healthcare professionals, family, friends, and peer groups can be a great source of the encouragement and emotional support you’ll need to thrive.

In-person or virtual support groups where you can share experiences and gain insight from others who get it can be empowering, motivating, and calming.

Eating Disorders, Mental Health, and Long-Term Recovery

Eating disorders can profoundly impact mental health and cognitive function, and addressing these issues requires a comprehensive, holistic approach that extends even beyond initial recovery.

High-performing individuals need to understand that mental and physical health are inseparable–both contribute equally to long-term success and wellbeing. By taking proactive steps to address an eating disorder and the mental health impact it has, you can protect your cognitive abilities, sustain your performance, and get back on track.

If you’re struggling with an eating disorder–or suspect you may be–the time to act is now. Reach out for a consultation.
