Researchers examining the relationship between alcohol consumption and food choices have identified a potentially important link: alcohol may influence hormonal signals that drive preferences for savory, high-fat foods.
A review published in Obesity Reviews analyzing data from interviews with more than 9,000 Australians found that people reporting alcohol consumption also reported eating significantly more savory foods and fewer sweet foods than non-drinkers. The research suggests that alcohol may increase levels of a hormone called FGF21, which increases preference for savory (umami) foods while reducing sweet preference.
The concern arises when this hormonal shift combines with access to ultra-processed savory foods. According to the analysis, people consuming alcohol alongside a diet rich in ultra-processed savory foods with low protein and high fat took in 40% more calories than the daily recommendation—before accounting for the alcohol itself. The researchers hypothesize that these ultra-processed foods act as “protein decoys,” failing to deliver adequate protein satisfaction despite tasting savory, leading people to consume more calories seeking satiation that never comes.
The researchers note their observations were limited to secondary analysis of survey data and did not directly measure FGF21 levels. They concluded that “advice to limit highly processed foods, including savory snack foods, may be even more critical than previously thought for reducing the risk of weight gain among adults who drink regularly.” A registered dietitian quoted in the reporting recommended eating a substantial meal containing protein, fiber-rich carbohydrates and healthy fats before drinking, and keeping minimally processed snacks readily available to reduce late-night convenience food consumption.
