A large-scale change in appetite doesn't just affect calories. It can alter package size, frequency, household waste, shopping basket composition, indulgence categories, and the economics of the aisles.

The Problem Behind the Number
The managerial risk is importing conclusions from the United States as if they were a ready-made forecast for Brazil. Penetration, income, access, food culture, and relative prices are different. There is international evidence of change; however, a Brazilian series capable of isolating the effects of medication, inflation, and income is still lacking.
THE NUMBER THAT MATTERS

- Circana projects that GLP-1 users could account for 35% of food and beverage sales in the US by 2030. Source: Circana, 2024.

The numbers above are not interchangeable: each source works with its own period, panel, and methodology. They serve as converging or contrasting signals, not as a single statistical series.
Proven Fact, Observed Trend, and Hypothesis
Proven facts. These are the data attributed to the indicated sources and years. They describe the samples and periods studied.
Observed trend. A combined reading points to a change in basket composition, greater pressure on productivity, and the need to manage price, volume, mix, and availability separately. A trend is not destiny: format, region, and audience may behave differently.
Author's hypothesis. My hypothesis is that GLP-1s will accelerate existing trends—smaller portions, higher nutritional density, and selectivity—more than they will create an entirely new consumer. The advantage will go to those who measure early without labeling people.
Impact on Operations
IMPACT ON OPERATIONS
Every change in consumption culminates in concrete decisions about purchasing, inventory, pricing, planograms, scale, production, supply, and customer service. If an indicator doesn't reach these routines, it hasn't yet become management.
- Create anonymous cohorts for basket changes, without inferring individual health conditions.
- Track units, grams, and frequency for proteins, fresh produce, indulgence items, and beverages.
- Test smaller portions without confusing size reduction with a disguised price increase.
- Review the display and supply of nutritionally dense categories.
Opportunities for Operators
The most consistent response is not an opportunistic shelf 'for users.' It is to improve what should already be working: clear information, appropriate portions, freshness, protein, convenience, loss prevention, and mission-driven assortment.
Implementation should start small: select comparable stores, define a hypothesis, record a baseline, test for a sufficient period, and measure the total effect—including item cannibalization, waste, availability, and additional labor. Scaling without this design turns opinion into cost.
WHAT I WOULD TRACK
Revenue, volume, units per receipt, frequency, contribution margin after losses, availability of critical items, and operational productivity. The priority changes by topic, but none of these indicators should be read in isolation.
Questions for Managers
QUESTION FOR THE MANAGER
- Which categories change in units and which only in value?
- Does the chain know how to measure grams per basket and not just items?
- How to avoid making health promises while still responding to new shopping missions?
Conclusion
The transformation of food retail doesn't just happen in strategic presentations. It shows up on the loading dock, in the stockroom, on the shelf, in the price, at the checkout line, and in the shopping cart. The role of leadership is to distinguish noise from structural change and convert insights into operational routine.
