From booze to betting to fitness: How GLP-1s are changing behavior – CNN

You’re reading about a class of medicines that started in the clinic for diabetes and ended up in headlines about weight, glamour, and lifestyle. The conversation isn’t just clinical anymore; it’s cultural. You’re being invited — sometimes forcefully, sometimes subtly — to consider how a biochemical nudge can alter what you drink, how you gamble, and whether you lace up your shoes.

What are GLP-1s?

You should think of GLP-1s as molecules that talk to several parts of your body at once. GLP-1 stands for glucagon-like peptide-1, a hormone your gut releases after you eat that signals fullness and helps manage blood sugar.

These medications are GLP-1 receptor agonists, which means they mimic the hormone’s effects for longer and stronger than your body usually does. They were developed to treat type 2 diabetes and later found to produce meaningful weight loss, which propelled them into mainstream attention.

The biology in plain language

If you want a simple mental model, imagine GLP-1s as an internal messenger who both quiets the stomach’s hunger signals and talks to your brain’s reward center. That conversation changes how you experience food and other pleasurable behaviors. You feel satisfied more quickly, and some of the hedonic pull of certain rewards is reduced.

Molecules in your brain, like dopamine, carry the sense of reward. GLP-1s don’t directly change dopamine levels in the simplistic sense, but they interact with brain circuits that shape craving, reinforcement, and the urge to seek out behaviors that once felt irresistible.

Common GLP-1 drugs and how they’re used

Pharmaceuticals in this space include drugs you may have heard about: semaglutide, liraglutide, exenatide, and tirzepatide (which acts on two hormones). Some are clearly labeled for diabetes, others for chronic weight management, and some are prescribed off-label for weight with mounting demand.

Below is a concise table to orient you around the main players, their branded names, and the typical uses and side effects you should know.

You deserve to know that while these medications can be transformative for some people, they’re not inert. They change how your body registers hunger and pleasure, and that has ripple effects beyond the scale.

How GLP-1s change appetite and weight

When you take a GLP-1 agonist, you’re shifting both physiological and psychological determinants of eating. Your stomach signals fullness earlier; your brain interprets food as less urgently rewarding. That’s a powerful combination for weight reduction.

But weight loss is multifactorial. The medication provides leverage by changing internal drivers, and many people pair it with lifestyle change, therapy, or simply a different relationship to food. You can’t think of the drug as magic that replaces context, but it can be a formidable aid.

Appetite suppression vs metabolic change

You should separate appetite suppression — the felt decrease in hunger — from changes in metabolism or energy expenditure. GLP-1s mainly work by reducing what you want to eat and by slowing gastric emptying. They’re not primarily thermogenic; they don’t make you burn calories just by existing.

That distinction matters because it shapes expectations. If you expect to eat the same amount and maintain your previous activity, you’re missing the point. The medication reduces intake and lets other behavioral changes become more sustainable.

What research shows about weight loss

Clinical trials show that semaglutide and tirzepatide can produce significant weight loss for many people, sometimes rivaling results from bariatric surgery. You should note these are averages across study populations; individual responses vary widely. The sustained benefit often requires continued treatment — stop the medication and weight often returns.

You must also know that these trials usually include behavioral support and structured programs. The medication’s effect is amplified by counseling, dietary changes, and physical activity. Researchers are still working to untangle how much of the improvement is medication versus the combined package.

Alcohol and GLP-1s: less desire, real results?

You might be surprised to learn that gut hormones influence addictive behaviors. Animal studies have repeatedly shown that GLP-1 receptor agonists reduce alcohol intake in rodents. That finding has provoked questions about whether these drugs could help people reduce problematic drinking.

Early human research is promising but preliminary. Some small trials and observational studies suggest reductions in alcohol intake among people taking GLP-1 agonists. But the evidence is not yet robust enough for GLP-1s to be standard treatment for alcohol use disorder.

Animal studies and early human data

In experiments with rodents, GLP-1 agonists reduce the preference for alcohol and decrease consumption. These models help scientists map the brain circuitry involved in reward-seeking, showing GLP-1’s influence in regions linked to addiction.

Human data is sparser. Small-scale studies and patient reports highlight decreases in alcohol cravings and intake, but sample sizes are limited and confounding factors abound. You should treat early human evidence as hypothesis-generating rather than conclusive.

How GLP-1s might reduce drinking

The most plausible mechanism is that GLP-1s dampen the reward value of alcohol. If drinking becomes less rewarding, you’re less likely to seek it. Additionally, slower gastric emptying and the uncomfortable GI side effects some people experience can make drinking less pleasant, providing a behavioral deterrent.

But you must recognize that addiction is not only about reward; it’s also about coping, sociality, and conditioned cues. A pill that changes reward valuation may not address the social triggers or psychological needs that sustain heavy drinking.

Clinical implications and caveats

If you’re using GLP-1s and notice decreased drinking, that may be beneficial, but it’s no substitute for addiction treatment when dependence exists. Sudden changes in drinking behavior can also have medical consequences; if you stop heavy drinking abruptly, you need medical supervision.

And remember, correlation is not causation. People who start GLP-1s often change diet, lifestyle, and social habits in ways that reduce drinking. Some patients report substituting one behavior for another — eating less yet spending more time online or finding other rewards. Watch for behavioral shifts that trade one coping strategy for another.

Gambling, impulse control, and reward

You might imagine GLP-1s as affecting only food and drink, but reward circuits are shared across many behaviors, including gambling and other forms of impulsivity. Early animal models suggest GLP-1 receptor activation can reduce the pursuit of non-food rewards, which opens a window into how these drugs might affect gambling or compulsive behaviors.

Scientific evidence in humans is still emergent. There are sparse case reports and exploratory studies suggesting reduced impulsivity and decreased pathological gambling behaviors among some people taking GLP-1 analogs. The data are intriguing but not definitive.

Evidence linking GLP-1 to reduced impulsive behaviors

Researchers have observed lower compulsive-seeking behavior in rodents treated with GLP-1 agonists when those rodents are offered drugs or sucrose. Those same neural pathways underpin aspects of gambling: reward expectation, reinforcement, and risk-taking.

For you, that may mean a medication could lessen the urge to place that compulsive bet or check the odds compulsively. But the clinical translation requires larger, controlled human studies to confirm safety and efficacy for impulse-control disorders.

Mechanisms: reward circuits and dopamine

GLP-1 receptors are expressed in brain regions tied to reward processing, including the ventral tegmental area (VTA) and nucleus accumbens. By modifying signaling in these areas, GLP-1s can change how enticing a reward feels. That doesn’t mean dopamine is simply turned down; rather, the relationship between cue and reward is altered.

You should be cautious about overinterpreting this: altering reward sensitivity broadly could reduce harmful behaviors but might also blunt positive motivation for healthy pursuits. The subtleties of these effects require careful, person-centered attention.

Fitness and movement: motivation, capacity, and side effects

When you lose weight, movement often becomes easier. GLP-1s can facilitate that process by reducing the physical burden of excess weight and improving glycemic control or joint pain. Many people report feeling more able to exercise, and with greater comfort, which can set off a positive feedback loop improving fitness.

Yet the drugs can also produce side effects that interfere with activity: nausea, gastrointestinal discomfort, and fatigue. You may not immediately feel energized, and exercise tolerance can vary week to week as your body adjusts.

Physical changes that support activity

As you lose weight, biomechanics change: joints bear less load, breathing may become easier, and small physical tasks require less exertion. That can motivate you to try new forms of movement, or to stick with walks and strength training that were previously painful.

These gains are meaningful because sustainable physical activity is often what maintains weight and improves cardiometabolic health. The medication can give you the physical headspace to re-learn movement as pleasurable rather than punishing.

Fatigue, nausea, and exercise: practical concerns

You should expect a period of adjustment. Early on, nausea and reduced energy can make a workout feel worse, not better. For some people, taking the medication at a time of day that minimizes GI effects, adjusting intensity, and focusing on low-impact activities helps.

Communicate with your clinician if side effects interfere with movement. Small adjustments — hydration, meal timing, and a slower ramp into exercise — can make a difference so that the benefits of weight loss aren’t overshadowed by short-term discomfort.

Mental health, eating disorders, and identity

You’re not just a body; you’re a person with an identity shaped by food, body, and culture. GLP-1s can alter the relationship you have with eating, and that can be liberating for some and destabilizing for others. People with histories of disordered eating need particularly close monitoring, because hunger cues and control narratives can be affected in complicated ways.

Beyond eating disorders, mood changes can occur. Some people report improvements in self-esteem with weight loss, while others notice anxiety or low mood as aspects of their identity shift. Medication can disrupt narratives you’ve used to understand yourself; that’s not a trivial side effect.

Risks for people with disordered eating

If you have a history of anorexia nervosa, bulimia, or binge-eating disorder, be careful. GLP-1s can mask binge-eating by reducing appetite, but they don’t treat the psychological drivers of disordered eating. Conversely, restricting intake because of medication effects can appear like remission but may conceal ongoing issues.

You should have a treatment team that includes a clinician familiar with eating disorders if you’re considering GLP-1s with that history. The medication may be contraindicated or require close psychological oversight.

Mood effects and suicidality signals

Clinical trials track mood outcomes and rare signals like suicidality. The overall evidence hasn’t shown a clear, consistent increase in suicide risk attributable to GLP-1s, but individual cases and the emotional consequences of rapid body changes warrant attention. You should monitor mood changes and report them promptly.

If weight loss significantly alters how others treat you — socially or professionally — that social feedback can impact mental health in ways medication doesn’t address. Your emotional world deserves as much attention as your body’s metabolic state.

Social and cultural consequences

You’re living in a moment where medication is a quick fix for structural problems that didn’t appear overnight. GLP-1s intersect with culture: the way we value thinness, productivity, and self-control. Broad adoption of these drugs will have ripple effects across workplaces, social life, and public opinion.

Expect shifts in stigma. People who once felt moralized for their bodies may find relief, but new norms may emerge that judge those who choose not to take medication. Society’s appetite for quick solutions can obscure the deeper causes of poor health — poverty, food environments, trauma, and stress.

Weight stigma, access, and inequality

If you have resources, a prescriber, and insurance, you may get access to these medications. Many others won’t. That inequality exacerbates existing health disparities: those least responsible for structural drivers of poor metabolic health may be least able to obtain the pharmacological tools others use to change bodies.

This unequal access creates a new axis of social advantage. Employers, insurers, and clinicians will need ethical guidelines that consider fairness, not just efficacy.

Commercialization and cosmetic use

You should notice how the conversation around GLP-1s has been shaped by celebrity narratives and direct-to-consumer hype. The drugs are medical, but they’re profitable. Prescribing patterns sometimes follow demand for cosmetic weight loss rather than clinical need.

That commercialization risks medicalizing non-pathological body diversity and redirecting resources away from public health approaches that would have broader benefit.

The ethics of behavior-altering medication

You likely think of medication as a clinical intervention, not a moral arbiter. But when a drug changes how you make choices, ethical questions multiply. Who decides whether it’s appropriate for someone to use medication that shifts their impulses? How does consent look when social pressure to conform is high?

There’s no simple answer. Ethical prescribing requires transparency about benefits and limits, attention to structural drivers of behavior, and respect for individual autonomy.

Autonomy, consent, and medicalization

Your autonomy matters. You deserve full information about how GLP-1s might alter your cravings, mood, and identity. Consent is meaningful only when you understand the social context and potential long-term dependence on the medication for weight maintenance.

You should resist framing non-use as failure. Medicalization can delegitimize other valid approaches to health and well-being, and clinicians must avoid coercive messaging that treats medication as the only acceptable path.

Where should policy focus?

Policy should prioritize equitable access, long-term safety monitoring, and protections against employment or insurance discrimination based on medication use. Public health investments in the food environment, access to mental health care, and social supports should not be supplanted by a pill as the main solution.

Regulatory agencies should mandate clear labeling about behavioral effects and encourage research into consequences beyond weight loss — including mood, addiction, and impulse control.

What you should know if you’re considering GLP-1s

If you’re thinking about starting a GLP-1, ask questions and set realistic expectations. This medication can be a tool, not a totalizing answer. You are deserving of a plan that addresses both biology and context.

Be prepared for early side effects and a variable emotional experience. Your clinician should help you set goals that aren’t solely weight-centric and should monitor mental health and eating behaviors proactively.

Questions to ask your clinician

• What is your primary goal for prescribing this medication, and how will we measure success?
• How long should I expect to take the medication, and what happens if I stop?
• What are the risks specific to my medical and psychiatric history?
• How will we monitor mood changes, eating behaviors, and substance use?
• What behavioral supports (nutrition counseling, therapy, physical activity programs) do you recommend alongside medication?
• How does this medication interact with any other drugs or supplements I take?
• What are the financial costs, and is there support for access if insurance denies coverage?

You should leave the appointment with clear, written expectations and a safety plan for side effects or mood changes.

Practical monitoring and lifestyle pairing

Pair the medication with behavioral strategies. Track mood and craving changes in a journal. Keep regular follow-ups with your clinician for the first months. If you have a history of problematic alcohol use or gambling, involve specialists early.

Small, sustainable changes in activity and sleep will amplify the medication’s benefits. Think of the drug as lowering resistance so you can rewire habits, not as the habit rewiring itself automatically.

Gaps in research and what to watch for

You deserve clarity about the unknowns. Long-term effects of GLP-1 use — beyond five years — are not fully understood in large, diverse populations. The behavioral consequences, particularly when used for non-diabetic weight loss in younger or psychiatric populations, need more study.

Additionally, research needs to examine who benefits most and who is at risk for adverse psychological outcomes. The heterogeneity of response is significant and underexplored.

Long-term outcomes we need

We need studies that track weight, metabolic health, mental health, addiction-related outcomes, and quality of life for many years. You want to know not just that you lost weight, but whether the medication improved your life in ways that mattered to you and whether those improvements persist.

We also need research that includes people from varied racial, socioeconomic, and gender backgrounds. Without that, conclusions will be biased and potentially harmful.

Regulatory and societal monitoring

Regulators should require post-marketing surveillance that includes behavioral endpoints. You should be able to access transparent reports about adverse events and long-term trends in use. Societal monitoring should include how these drugs affect labor markets, insurance practice, and social norms around bodies.

Civil society and clinicians should push for policies that protect patients from discrimination and that reinvest some of the profits into community health programs.

Final thoughts

If you choose to take a GLP-1 medication, do so with eyes open. This is not a story solely about pharmacology; it’s about how a society with limited patience for structural change reaches for biomedical solutions that change not just bodies but choices. The drug can be a liberation from hunger and a bridge to healthful habits, or it can be a cosmetic fix that deepens inequities and masks deeper needs.

You deserve care that treats you as a whole person — your biology, your history, your relationships, your context. Ask hard questions, insist on humane and comprehensive care, and remember that medication should expand your options rather than narrow them. The conversation about GLP-1s is too important to leave to headlines and advertisements. Be part of shaping it with curiosity, skepticism, and compassion.
