GLP-1 weight-loss medications are changing how people approach food and drink. By reducing appetite and increasing feelings of fullness, GLP-1 diets naturally shift focus towards lower calorie density and fewer “empty” calories. As a result, drinks that once felt insignificant can have a bigger impact on overall intake.
One of the most common questions people ask is what they can drink on a GLP-1 diet. While there are no strict rules, the most suitable drinks tend to be simple, lower in calories and free from unnecessary sugars or additives.|
TL;DR // On a GLP-1 diet, drinks with fewer calories and less sugar are generally better suited when appetite and portion sizes are reduced.
Why Drinks Matter More on a GLP-1 Diet
When appetite is reduced, people naturally consume less food overall. This makes the calorie contribution of drinks more noticeable. Sugary drinks, creamy coffees and calorie-heavy smoothies can quickly take up a disproportionate share of daily intake without providing lasting satisfaction. GLP-1 users often report greater sensitivity to sweetness and heaviness, making lighter drinks easier to tolerate and more enjoyable.
Best Drinks to Choose on a GLP-1 Diet
Water and Sparkling Water
Water remains the most important drink on a GLP-1 diet. Still or sparkling water provides hydration without calories, sugar or digestive burden, and helps support overall wellbeing.
Tea and Herbal Infusions
Unsweetened tea and herbal infusions are naturally low in calories and can be comforting when appetite is low. Avoid adding sugar or syrups where possible.
Coffee (Black or Lightened)
Black coffee contains virtually no calories. For those who prefer milk, using a lighter, low-calorie option helps keep overall intake balanced.
Low-Calorie Plant-Based Milks
Not all plant-based milks are equal. Lower-calorie, low-sugar options without added oils are generally better suited to GLP-1 diets. MYOM is a good example of a lower-calorie oat milk brand designed to reduce sugar, fat and unnecessary additives compared to typical carton oat milks.
Drinks to Limit on a GLP-1 Diet
Sugary soft drinks, fruit juices and heavily sweetened smoothies can deliver large amounts of sugar quickly, which may feel overwhelming when appetite is reduced. Alcohol can also be harder to tolerate on GLP-1 medications and adds calories without nutritional value.
Best Milk Choices for Coffee and Tea on GLP-1
Milk is often added without much thought, but on a GLP-1 diet it can significantly affect calorie intake. Many carton oat milks contain higher sugars and additives to improve texture. Choosing a lighter milk with fewer calories and less sugar helps keep everyday drinks aligned with GLP-1 eating patterns, without giving up taste or routine.
Final Takeaway
There is no single “perfect” drink on a GLP-1 diet, but simpler choices tend to work best. Drinks that are lower in calories, lower in sugar and minimally processed are easier to enjoy when eating less overall. GLP-1 diets are encouraging a broader shift towards precision rather than restriction. Choosing drinks that earn their place fits naturally into that change.
