New research from IFF suggests the GLP-1 boom is doing more than shrinking portion sizes on Indian plates — it’s reshaping how consumers relate to food altogether, from the sensory experience of eating to the discomfort of skipping second helpings at a family gathering.

The study, “Inside the India GLP-1 Consumer Journey,” was unveiled at IFF’s Eat Smart Asia: The GLP-1 Shift symposium in New Delhi and builds on the company’s 2025 GLP-1 Consumer Opportunity Outlook. It draws on research conducted among GLP-1 users in Delhi, Mumbai and Bengaluru, tracking how changing appetites are influencing food choices, sensory expectations, shopping habits and social eating occasions.

“We are seeing that a change in appetite can lead to a broader change in the relationship people have with food, from how much consumers eat to how they choose, experience and participate in eating occasions,” said Harsch Koshti, regional marketing director, IFF Taste for Greater Asia. “For the food industry, this is a critical opportunity to listen closely to these emerging behaviours and think about how innovation can address these needs.”

Smaller portions, higher stakes

The report documents striking shifts in everyday portion sizes: consumers moving from three or four chapatis to one or two, from five or six idlis to two, and from 2.5 bowls of rice to half a bowl. But the research is careful to note that eating less doesn’t mean caring less — if anything, the opposite. When consumers eat smaller amounts, every bite is expected to work harder, raising the bar on nutrient density, taste, texture and overall satisfaction.

That pressure shows up clearly in the data on sensory perception: 90% of respondents reported changes in how food tastes or feels, 50% said they now prefer soft, easy-to-digest textures, and 69% said they want to balance flavour impact. For product developers, the findings point toward an opening for formulations that deliver concentrated nutrition and sensory payoff within a much smaller footprint.

The social dimension of eating is shifting too. Nearly two-thirds of respondents — 64% — said they experience social eating discomfort at least occasionally. Yet the report suggests most consumers still want to stay engaged in shared food occasions rather than opt out of them, which points to demand for products and formats that help people participate normally even as their own consumption patterns change.

A more deliberate shopper — but not always at home

Label scrutiny has intensified sharply: 74% of respondents said they now read food labels more carefully than before starting GLP-1 medication, with attention extending well beyond calorie counts to protein content, ingredient lists and natural or preservative-free claims. That raises the bar for how brands communicate nutrition and ingredient value on pack.

Household purchasing, however, tells a more complicated story. Despite the shift in individual eating habits, 78% of respondents said they continue buying biscuits for their households, 71% continue buying packaged sweets and full-fat dairy, and 63% continue buying fried snacks. In other words, personal consumption is evolving faster than the family shopping basket — a gap that complicates any assumption that brands simply need to launch “GLP-1-friendly” products. Food choices, the report notes, remain deeply embedded in household and family routines that don’t shift as quickly as individual appetites do.

Hydration gets a wellness upgrade

The GLP-1 effect extends to beverages as well. Some 74% of respondents said they now view hydration as a daily wellness goal, with many gravitating toward coconut water — chosen by 69% as part of their hydration habits — and electrolyte-based drinks. IFF points to this as evidence of growing demand for beverages that combine functionality, hydration and sensory appeal.

Consumption shifts

IFF frames the opportunity here as extending well beyond weight management itself: as appetites, portion expectations and sensory needs continue to evolve among GLP-1 users, food and beverage companies may need to rethink how they deliver nutrition, enjoyment and value across eating occasions — not just in dedicated diet categories, but across the mainstream products already sitting in Indian shopping baskets. Variables to watch include how quickly household purchasing habits catch up with individual consumption shifts, whether manufacturers reformulate mainstream lines for smaller, more nutrient-dense portions, and how the social-eating discomfort documented in the report translates into demand for new formats built around participation rather than restriction.
