GLP-1 Use and Protein Demand Create Growth Opening for Dairy Products

Weight-management drugs reshape grocery demand

Growing use of GLP-1 medicines for weight management is creating a potential growth channel for milk and other dairy products as consumers place greater emphasis on protein and nutrition. The shift could benefit processors of yogurt, cottage cheese, whole milk and dairy proteins, even as the medicines reduce overall household food spending.

According to figures cited by Merca2.0, Gallup estimates that 11% of US adults currently take a GLP-1 medicine to lose weight. KFF puts usage at 12% when all medical purposes are included. The drug category includes semaglutide, sold under the Ozempic brand, while Mounjaro contains tirzepatide and acts on two receptors.

A study by Cornell University and Numerator, published in the Journal of Marketing Research, found that household grocery spending falls by an average of 5.3% during the first six months of GLP-1 treatment. The decline exceeds 8% among higher-income households. Spending on snacks falls by about 10%, while purchases of bread, meat and eggs also decrease. Yogurt is one of the categories that records growth.

The findings suggest that GLP-1 adoption is doing more than reducing the volume of food consumed. It is also changing the mix of products in shopping baskets. For dairy businesses, the commercial opportunity therefore appears concentrated in products associated with protein, satiety and portion-controlled nutrition rather than across the entire category.

Yogurt and cottage cheese lead dairy growth

US production and retail data cited by Merca2.0 indicate that the demand shift is already visible. The National Milk Producers Federation reported that yogurt production increased by nearly 6% in the first half of 2026, while cottage cheese output rose 12%. Retail sales of whole milk increased by around 4% over the same period.

These gains are encouraging dairy companies to reposition products that were traditionally marketed primarily to children and families. Yogurt, Greek yogurt and cottage cheese can instead be presented to adults seeking convenient sources of protein and nutrition. Milk is consequently attracting more commercial attention at a time when demand for some snack foods and alcoholic beverages is weakening.

Gallup data cited by Merca2.0 show that 54% of US adults consume alcohol, the lowest share since 1939. Among people aged 18 to 34, the rate has fallen to 50%, down 22 percentage points from two decades earlier. Milk is not necessarily replacing beer directly, but the parallel trends may redirect marketing budgets and product development toward non-alcoholic, nutrition-focused beverages.

Trade tensions could affect dairy suppliers

The opportunity is emerging alongside renewed friction in dairy trade. Merca2.0 reported that Canada announced retaliatory tariffs on August 25, 2026, including a 50% duty on powdered milk, powdered cream and dairy proteins. Cheddar, mozzarella and Parmesan were assigned a 25% tariff.

The United States purchased $780 million of Canadian dairy products in the previous year, according to the publication. The measures could therefore affect suppliers and buyers on both sides of the border, particularly in processed dairy ingredients and cheese. In Mexico, the National Milk Producers Federation is also pressing its position under the US-Mexico-Canada Agreement over cheese names.

No comparable GLP-1 purchasing data were provided for Mexico, and Merca2.0 characterized a similar shift there as an expectation rather than an established trend. Access to the medicines may also limit the size of the affected consumer group. Producers and investors will need to distinguish sustained changes in dairy consumption from short-term marketing momentum while monitoring drug adoption, retail volumes and trade policy.
