GLP-1: The Hormone That’s Redefining Eating Habits and Big Food

For decades, Big Food has successfully marketed ultraprocessed products to consumers whose biological and psychological cravings drove overconsumption. From sugary cereals to savory snacks, these products were designed to exploit the brain’s reward system, often bypassing natural satiety signals and encouraging addictive eating patterns. Now, the landscape is shifting dramatically with the rise of GLP-1 receptor agonists such as Ozempic, Wegovy, and Zepbound, which directly target these mechanisms, fundamentally altering the way people experience hunger, cravings, and fullness.


The Science of GLP-1: How It Works

The active ingredient in these medications mimics glucagon-like peptide-1 (GLP-1), a natural hormone produced in the intestines. GLP-1 serves multiple critical functions:

  1. Slowing Digestion: By reducing the rate at which food moves through the stomach, GLP-1 helps people feel full for longer periods, decreasing the likelihood of overeating.
  2. Signaling Fullness to the Brain: GLP-1 communicates directly with the hypothalamus, the brain’s hunger-regulation center, helping to suppress appetite.
  3. Regulating Dopamine: By moderating the brain’s dopamine reward system, GLP-1 reduces the emotional pull of high-calorie, ultraprocessed foods, which are engineered to be highly rewarding.

In essence, GLP-1 acts as a biological reset for people with compulsive eating tendencies, rebalancing their relationship with food.


How GLP-1 Is Disrupting Big Food

For decades, the food industry capitalized on products that exploit sensory-specific satiety (the tendency to lose interest in a strongly flavored food after consuming it) and engineered cravings. Products like chips, cookies, and sugary beverages are often formulated with precise ratios of sugar, salt, and fat to hit the “bliss point”—the level of flavor intensity that keeps consumers eating more without realizing they’re full.

A Sudden Shift in Consumer Behavior

GLP-1 receptor agonists are turning this strategy on its head by fundamentally altering how individuals respond to food:

  1. Less Food, Fewer Calories: On GLP-1 drugs, people consume fewer calories—sometimes as little as 1,000 per day—half the minimum recommended intake for men.
  2. Preference for Whole Foods: Many GLP-1 users report losing their taste for ultraprocessed snacks and sugary treats, opting instead for fruits, vegetables, lean proteins, and other whole foods.
  3. Aversion to Junk Food: Anecdotal evidence and focus groups reveal that former junk food enthusiasts now find these products overly sweet, artificial, or “plasticky.”

The Implications for Big Food

Declining Sales

Big Food is already feeling the effects. Sales of sweet baked goods and ultraprocessed snacks are declining, as noted by Walmart’s U.S. Chief Executive, John Furner, who reported that customers using GLP-1 medications are putting fewer processed foods in their carts.

Fewer New Products

Market research indicates that food-and-drink innovation hit an all-time low in 2024, with fewer new ultraprocessed products entering the market. Instead, companies are pivoting to smaller portion sizes, higher protein content, and nutrient-enriched offerings to cater to this new demographic.


GLP-1 and Consumer Psychology

Unlike traditional diets that rely on willpower, GLP-1 drugs change the underlying biology of food consumption. By reducing the dopamine hit from junk food, these medications appear to “rewire” taste preferences, breaking the cycle of addiction that has fueled the ultraprocessed food industry for decades.

From Cravings to Clarity

Many GLP-1 users describe rediscovering the natural flavors of whole foods. A carrot tastes like a carrot, and celery is appreciated for its own flavor profile, not as a vehicle for dips or dressings. This newfound clarity in taste preferences has profound implications for the future of food marketing, which must now appeal to a population that values simplicity over excess.


Adapting to the GLP-1 Era: Big Food’s Next Move

Major food companies are scrambling to stay relevant:

  1. Smaller Portions: Nestlé’s new Vital Pursuit line targets GLP-1 users with reduced-calorie frozen meals like pizza and chicken bowls.
  2. High-Protein Snacks: Products like Fairlife’s sweet protein shakes, owned by Coca-Cola, are thriving among GLP-1 users who prioritize protein intake for muscle maintenance.
  3. Fresh and Whole Foods: With consumers gravitating towards produce, companies may find opportunities in fresh, minimally processed food offerings.

Risks of Overengineering

However, experts warn of the potential for the food industry to counteract GLP-1 drugs’ effects by engineering new hyper-rewarding compounds. Such innovations could dilute the benefits of these medications, reigniting addictive eating behaviors.


GLP-1 and Broader Health Implications

The effects of GLP-1 drugs extend beyond appetite suppression and caloric reduction. Preliminary research suggests potential benefits in reducing the risks of conditions like:

  • Alzheimer’s Disease and Dementia: GLP-1 receptor agonists may protect against cognitive decline by improving brain glucose metabolism and reducing inflammation.
  • Stroke and Cardiovascular Disease: These medications lower inflammation, improve insulin sensitivity, and may reduce stroke risk.
  • Addiction: GLP-1’s regulation of the dopamine reward system shows promise in treating dependencies on alcohol, nicotine, and drugs.

The Future of Food in a GLP-1 World

As GLP-1 drugs reshape consumer habits, the food industry faces an inflection point. The era of engineering food to exploit cravings may give way to a focus on simplicity, nutrition, and functionality. However, this transition will require companies to prioritize public health over short-term profits—a challenge given the history of food marketing.

A Question of Ethics

Can Big Food align with the health-focused priorities of GLP-1 users without resorting to strategies that undermine the drugs’ effectiveness? This question will shape the next decade of food innovation.


Conclusion

GLP-1 receptor agonists represent a seismic shift in how we eat and what we value in food. By altering the biology of hunger and cravings, these drugs are challenging decades of Big Food’s dominance in ultraprocessed products. The future of the food industry depends on its ability to adapt, innovate, and prioritize consumer health in an era where less truly is more.
