Does the evidence show GLP-1s actually cut alcohol cravings?
Yes, and the strongest direct evidence comes from a study that compared GLP-1 users to non-users using data from the All of Us Research Program. GLP-1 users drank significantly fewer drinks per day (p=0.0042), drank less frequently (p<0.0001), and had fewer heavy drinking episodes (p<0.0001) [2]. These are not small effects—they are statistically robust, meaning they are unlikely to be due to chance. Importantly, the benefit held regardless of the person's body mass index (BMI), suggesting the effect on alcohol craving is separate from weight loss [2]. However, this study was limited by a small sample size and a single point in time, so we cannot yet say how long the effect lasts.
What about cravings for addictive, ultra-processed foods?
The food-purchasing data is striking and comes from larger, more detailed studies. Households with a GLP-1 user reduced total grocery spending by 5.3% within six months, but the cuts were far bigger for the kinds of foods people often crave: savory snacks dropped 10.1%, and spending at fast-food chains and coffee shops fell 8.0% [1]. Another study using household scanner data found that GLP-1 adoption led to a systematic shift away from ultra-processed foods and toward minimally processed foods, with total food spending dropping by about $56 per month [4]. This is not just about eating less—it is about changing what you reach for. The largest reductions hit calorie-dense, processed categories, which are the ones most linked to addictive eating patterns [1][3].
What is the catch? Do these effects last?
The effects are real but not permanent for everyone. One study tracked households over a full year and found that the reductions in food spending and shifts away from junk food persisted through the first year, but they began to fade after six months [1]. Even more telling: when people stopped taking GLP-1s, their grocery spending bounced back and their baskets actually became slightly less healthy than before they started [1]. This means the medication suppresses cravings while you are on it, but it does not rewire your brain permanently. Also, the strongest effects were seen in higher-income households—they cut grocery spending by 8.2% compared to 5.3% overall—suggesting that access and affordability play a role in how well these medications work in practice [1].

EXPRESS: The No-Hunger Games: How GLP-1 Medication Adoption is Changing Consumer Food Demand
Using survey and transaction data from a U.S. household panel, this study found that GLP-1 adoption led to a 5.3% reduction in grocery spending within six months, with the largest declines in savory snacks (-10.1%) and fast food (-8.0%); effects faded after six months and reversed upon discontinuation.
THE EFFECTIVENESS OF GLP-1 MEDICATIONS IN REDUCING ALCOHOL CONSUMPTION
Comparing GLP-1 users to non-users in the All of Us Research Program, this study found statistically significant reductions in drinks per day (p=0.0042), drinking frequency (p<0.0001), and heavy drinking episodes (p<0.0001), with no difference by BMI.
Shrinking appetites: Will GLP-1 adoption in high-income countries accelerate Big Food's push into low- and middle-income countries?
Reviewing early retail data, this paper reports that U.S. households with a GLP-1 user cut grocery spending by about 5% within six months, with larger declines in energy-dense snacks, and warns that food companies may shift marketing toward low- and middle-income countries as a result.
GLP-1 Medication Adoption and Household Demand for Ultra-Processed Foods
Using household scanner data and a staggered-adoption difference-in-differences design, this study found that GLP-1 adoption caused a $56/month reduction in total food spending and a systematic reallocation away from ultra-processed foods toward minimally processed foods.
GLP-1 Medications: Redefining Food Choices and Industry Trends
This synthesis of medical, behavioral, and economic evidence describes how GLP-1s suppress appetite, shift food preferences, and reduce grocery spending, and notes that food companies are responding with smaller portions and 'GLP-1 companion' products.
