Insights on mind & metabolic health

If you've opened a magazine, scrolled through social media, or talked to a friend in the last two years, you've probably heard about GLP-1 medications — Ozempic, Wegovy, Mounjaro. The hype is real. So is the confusion.

As a psychiatric mental health nurse practitioner with a specialty in obesity medicine, I see patients every week who come in with either sky-high expectations or serious misconceptions about these medications. My goal here is to give you the clearest, most honest picture I can.

What is a GLP-1, exactly?

GLP-1 stands for glucagon-like peptide-1 — a hormone your gut naturally releases after you eat. It signals your pancreas to release insulin, tells your liver to slow glucose production, and most importantly for weight, it travels to your brain and says: you're full, slow down.

GLP-1 receptor agonists (semaglutide, liraglutide, tirzepatide) mimic and amplify this signal. They slow gastric emptying, reduce appetite, and over time, help recalibrate the brain's reward response to food.

The mental health connection most people miss

Here's what the headlines rarely cover: GLP-1 receptors aren't only in your gut — they're throughout your brain. Emerging research suggests these medications may reduce addictive behaviors, lower anxiety, and improve mood in some patients. Conversely, a subset of patients — particularly those with a history of depression or disordered eating — may experience worsening mood, nausea-driven restriction, or what I call "GLP-1 induced undereating."

This is why a psychiatric assessment before or during GLP-1 therapy is not optional — it's essential. The medication doesn't work in a vacuum. It works in a person.

Who is a good candidate?

GLP-1 medications are generally indicated for adults with a BMI ≥30, or ≥27 with at least one weight-related condition (type 2 diabetes, hypertension, sleep apnea, etc.). But clinical eligibility is just the starting point. In my practice, I also look at:

• History of eating disorders (binge eating, restriction, purging) — requires careful monitoring
• Current psychiatric medications that affect weight or appetite
• Past trauma around food, body image, or weight stigma
• Support systems and behavioral readiness
• Thyroid history (personal or family history of medullary thyroid carcinoma is a contraindication)

What GLP-1s are not

They are not a cure. They are not a replacement for behavioral and psychological work. And they are not equally effective for everyone. Research shows that approximately 10–15% of patients are "non-responders" — they experience little to no weight loss. We don't yet fully understand why, but emerging evidence points to gut microbiome differences, genetic variants in GLP-1 receptor expression, and baseline insulin sensitivity.

Stopping the medication without a maintenance plan is also a real concern. The STEP 4 trial found that patients who discontinued semaglutide regained two-thirds of their lost weight within a year. This isn't a failure of willpower — it reflects the biological nature of obesity as a chronic condition.

My approach at Clarity

When I work with patients on GLP-1 therapy, I integrate psychiatric evaluation, metabolic monitoring, and behavioral support from the beginning. We talk about what the medication can and can't do. We identify any underlying anxiety, depression, or eating patterns that could interfere — or be made worse. And we build a plan that supports you beyond the prescription.

If you're curious about whether GLP-1 therapy might be right for you, I'd love to talk. A single consultation can help clarify a lot.

I've sat across from dozens of patients who have tried everything — tracked every calorie, completed every program, seen every nutritionist — and still can't make lasting progress with their eating or weight. When I dig a little deeper, anxiety is almost always part of the picture.

Not the "I'm nervous before a presentation" kind of anxiety. The low-grade, always-on, never-fully-at-rest kind that lives in your chest and never quite turns off. That kind of anxiety has profound effects on your metabolism and your relationship with food — and most of the time, nobody has connected those dots for you.

The cortisol-appetite loop

When you're anxious, your body activates its stress response. The hypothalamic-pituitary-adrenal (HPA) axis releases cortisol — the primary stress hormone — which does several things relevant to eating:

• Increases cravings for high-calorie, high-fat, high-sugar foods (the brain wants fast fuel)
• Promotes fat storage, especially in the abdomen
• Disrupts leptin and ghrelin — the hormones that regulate hunger and fullness signals
• Impairs the prefrontal cortex, making it harder to make intentional food choices

In other words: when you're chronically anxious, your biology is working against your best intentions at the dinner table.

The restrict-binge cycle in anxious eaters

Many anxious people develop what I call a compensatory eating pattern: they restrict during the day (anxiety suppresses appetite acutely) and overeat at night when the cortisol finally drops and the brain demands what it's been denied. This isn't a lack of willpower — it's neurobiology.

Restriction triggers anxiety. Anxiety disrupts hunger cues. Evening overeating follows. Guilt about overeating increases anxiety. The cycle repeats. Without addressing the anxiety itself, no eating plan will break this loop long-term.

Anxiety and metabolic health

Chronic anxiety is associated with insulin resistance, elevated fasting glucose, and increased inflammatory markers — independent of diet and exercise. A 2019 meta-analysis found that anxiety disorders were associated with a 37% increased risk of developing type 2 diabetes.

What actually helps

Treating anxiety — with therapy, medication, or both — often produces metabolic improvements that no diet alone can achieve. In my practice, I commonly see:

• Improved sleep (which directly lowers cortisol and normalizes appetite hormones)
• Reduced nighttime eating and cravings
• Greater ability to make intentional food choices
• More consistent energy and blood sugar throughout the day

We also work on nervous system regulation — breathing practices, routine, sleep hygiene — because the body can't distinguish between psychological anxiety and physiological stress. Calming one calms the other.

If you've been struggling with eating patterns and nobody has asked you about your anxiety level, that conversation is overdue.

One of the most common things I hear from patients is some version of: "I know I should eat better and exercise, but I just can't make myself do it." They're frustrated with themselves. They've internalized the message that this is a motivation problem, a character problem.

It's not. When depression is present, the brain's reward and motivation circuitry is literally impaired. This isn't metaphorical — it's neurological. And the relationship between depression and weight is a two-way street in ways that most people — and even many clinicians — don't fully appreciate.

The bidirectional relationship

Depression increases the risk of obesity. Obesity increases the risk of depression. Both share common underlying mechanisms — and treating one without addressing the other is like fixing half a circuit.

Shared biology: inflammation, dopamine, and HPA dysregulation

Three biological pathways link depression and weight in ways that make separating them nearly impossible:

1. Inflammation. Both obesity and depression are associated with elevated inflammatory markers. Inflammatory cytokines cross the blood-brain barrier and directly impair serotonin and dopamine synthesis — the neurotransmitters most disrupted in depression. Treating metabolic inflammation can meaningfully improve mood.

2. Dopamine dysregulation. Depression blunts the brain's reward response (anhedonia). Food — especially high-fat, high-sugar food — temporarily activates dopamine pathways. This is why comfort eating is so common in depression: it's the brain seeking relief, not a lack of willpower.

3. HPA axis dysregulation. Just like anxiety, depression disrupts the stress-hormone axis. Elevated cortisol promotes fat storage, disrupts sleep, and worsens insulin resistance — creating a metabolic environment that makes weight loss biochemically harder.

The medication question

Many patients worry — rightly — about antidepressants and weight. Some SSRIs, particularly paroxetine, are associated with weight gain over time. Others, like bupropion, are weight-neutral or may support modest weight loss. SNRIs vary. This is an important conversation to have explicitly with your prescriber.

In my practice, I consider both the psychiatric and the metabolic profile when choosing medications. There is no universal answer, but there are almost always options that serve both goals.

What integrated treatment looks like

In my experience, the patients who make the most sustainable progress are the ones whose depression is treated alongside their metabolic goals — not sequentially, but simultaneously. This means:

• Psychiatric medication thoughtfully chosen with metabolic considerations in mind
• Behavioral activation (structured, gentle movement as a mood and metabolic intervention)
• Sleep treatment — often the highest-leverage intervention in both depression and weight
• Nutritional psychiatry — using food quality, not just quantity, as part of mood treatment

You don't have to wait until your depression is "fixed" to work on your weight. And you don't have to tackle your weight alone while struggling with depression. Both deserve attention at the same time.

Almost every patient I see who struggles with emotional eating has, at some point, been told some version of "just don't eat when you're not hungry." As if the problem is simply not having noticed that advice before.

Emotional eating is not a knowledge problem. It's not a discipline problem. It is a nervous system regulation problem — and it has a neurobiological explanation that deserves to be understood, not moralized about.

What emotional eating actually is

Emotional eating is using food to manage internal states — stress, boredom, loneliness, anxiety, overwhelm — rather than physical hunger. It works, at least temporarily, because food activates the brain's reward and soothing systems:

• Carbohydrates briefly increase serotonin (the calming neurotransmitter)
• Fat and sugar activate dopamine (the reward neurotransmitter)
• The act of eating itself can activate the parasympathetic ("rest and digest") nervous system

In other words: your brain learned that food helps you feel better when you're dysregulated. That's not a character flaw — it's a learned coping mechanism. The problem is that it creates a cycle: emotional distress → eating → temporary relief → guilt or shame → more distress → more eating.

The binge eating connection

Binge Eating Disorder (BED) is the most common eating disorder in the United States — more prevalent than anorexia and bulimia combined — yet it is dramatically underdiagnosed. BED is characterized by recurrent episodes of eating large amounts of food, often rapidly and to the point of discomfort, accompanied by feelings of loss of control and significant distress.

BED is not a lifestyle issue. It is a psychiatric condition with established treatments, including specific forms of therapy (CBT, DBT) and FDA-approved medication (lisdexamfetamine/Vyvanse). Many patients have been living with it for years without ever receiving a proper diagnosis.

What actually changes the pattern

Restriction doesn't fix emotional eating — it makes it worse. Restriction increases the biological drive to eat, heightens the reward value of food, and adds shame to an already emotionally loaded behavior. The approach that actually works addresses the underlying emotion regulation deficit:

• Identifying triggers — what emotional states precede eating episodes?
• Building a regulation toolkit — alternative ways to address distress that your nervous system will actually accept
• Reducing food shame — neutralizing the moral weight placed on food and eating
• Treating underlying conditions — anxiety, depression, ADHD, and trauma are all common drivers
• Structured eating rhythms — regular meals reduce the biological vulnerability to emotional eating

This is nuanced work. It doesn't happen through a meal plan or an app. It happens in a therapeutic relationship where you feel safe enough to look at what's actually going on.

ADHD and eating disorders are linked far more often than either patients or clinicians realize. In my practice, I see this combination constantly — and yet most patients have never had anyone connect those dots for them. They've been told they "lack self-control" around food without anyone asking why, neurologically, self-control around food is so much harder for them.

ADHD is fundamentally a disorder of dopamine regulation. And food — especially high-reward, high-stimulation food — is one of the most reliable dopamine hits available. Understanding that connection changes everything.

How ADHD affects eating behavior

ADHD affects eating through multiple overlapping pathways:

1. Dopamine-seeking behavior. The ADHD brain is chronically understimulated in its reward circuitry. Food — particularly sweet, salty, fatty, or highly processed food — provides rapid dopamine stimulation. This is why many adults with ADHD gravitate toward highly palatable foods and struggle to feel satisfied by less stimulating options.

2. Impulsivity. Impulsive eating — eating before hunger registers, making food decisions without deliberate thought, difficulty stopping once started — is a direct expression of ADHD's core impulsivity symptoms. This is not a lack of caring about health. It's an executive function deficit.

3. Disrupted interoception. Many people with ADHD have difficulty detecting and interpreting internal body signals — including hunger and fullness. They may forget to eat for hours (hyperfocus), then overeat rapidly when they finally do. Or they may eat reactively, out of boredom or sensory-seeking, rather than hunger.

4. Emotional dysregulation. ADHD is strongly associated with emotional dysregulation — rapid, intense emotional responses that are harder to manage. Emotional eating (discussed in another post) is extremely common in this population as a result.

ADHD, weight, and the underdiagnosis problem

Adults with ADHD have higher rates of overweight and obesity than the general population. A large Danish cohort study found that adults with ADHD were approximately 1.5 times more likely to be obese — not because of laziness, but because of the neurobiological eating patterns described above.

What's particularly problematic is how often ADHD goes undiagnosed in adults — especially in women, who are historically underdiagnosed. Many of my patients with longstanding eating struggles turn out to have undiagnosed ADHD that has been driving their relationship with food for decades.

The treatment question: does ADHD medication help?

Stimulant medications (amphetamines, methylphenidate) used to treat ADHD are appetite suppressants — this is well established. For some patients, ADHD treatment has the secondary benefit of reducing impulsive eating and improving self-regulation around food. For others, medication-induced appetite suppression creates new problems: undereating during the day, then overeating at night when the medication wears off.

This is an individualized conversation. Non-stimulant options like atomoxetine or viloxazine may be more appropriate for patients where eating patterns are a significant concern. The key is that ADHD treatment and eating behavior should be considered together, not in isolation.

What I recommend for patients with ADHD and eating concerns

• Structured meal timing to counter hyperfocus-driven fasting and reactive eating
• Reducing decision fatigue around food (simplified, planned meals)
• Addressing emotional dysregulation as a core treatment target
• Considering whether stimulant timing interacts with eating patterns
• Screening for binge eating disorder, which requires specific treatment

If you've struggled with your relationship with food and also have (or suspect) ADHD, you're not alone — and there is a coherent explanation for what's been happening. Clarity is here for exactly this kind of integrated picture.
