The Best Weight Loss Drinks to Complement Mounjaro or Wegovy

If you are taking Mounjaro or Wegovy for weight loss, you are likely already thinking carefully about what you eat. But what you drink matters just as much. Certain drinks can support your progress, help manage side effects, and complement the appetite-reducing effects of your medication. Others can quietly undermine your results without you realising.

This guide covers the best drinks to include while on GLP-1 or GIP and GLP-1 based weight loss treatment, and which ones are best kept to a minimum.

Why What You Drink Matters on Weight Loss Medication

Mounjaro (tirzepatide) and Wegovy (semaglutide) work by reducing appetite and slowing gastric emptying. This means you will likely feel full more quickly and for longer. However, liquid calories are processed differently to solid food and can bypass the satiety signals these medications help to strengthen.

Drinks high in sugar, alcohol, or calories can add significant energy intake without triggering the fullness response that your medication supports with food. Being mindful of your choices is a straightforward way to make your treatment work harder for you.

Water: The Most Important Drink of All

Water is the single most important drink to prioritise during weight loss treatment. Both Mounjaro and Wegovy can cause gastrointestinal side effects including nausea, vomiting, and diarrhoea, particularly in the early weeks. Staying well hydrated helps manage these symptoms and supports overall health.

Aim to drink regularly throughout the day rather than in large amounts in one sitting, which can worsen nausea. If plain water feels unappealing, adding slices of cucumber, lemon, or mint can make it more palatable without adding meaningful calories.

Sparkling Water

Unsweetened sparkling water is a good alternative to still water and can help satisfy the craving for something more interesting without adding calories or sugar. Some patients find it useful as a replacement for fizzy drinks during treatment.

One consideration worth noting: sparkling water may worsen bloating or nausea in some patients, particularly early in treatment when gastrointestinal side effects are more common. If you notice this, sticking to still water during those early weeks may be more comfortable.

Green Tea

Unsweetened green tea is a useful addition to a weight loss-focused routine. It contains a modest amount of caffeine and antioxidants, and some research suggests it may support metabolism and fat oxidation to a small degree. While the effect on its own is not dramatic, it complements an already calorie-conscious approach without adding any calories.

Green tea is best consumed without added sugar or milk to keep it calorie-free. If you are sensitive to caffeine, be mindful of how much you consume, particularly later in the day.

Black Coffee

Black coffee, consumed without sugar or high-calorie additions, is low in calories and can help manage appetite between meals. Caffeine has a mild appetite-suppressing effect that can be a useful complement to the hunger-reducing properties of your medication.

However, coffee consumed on an empty stomach can worsen nausea, which is already a common early side effect of both Mounjaro and Wegovy. If you find this is an issue, having coffee with or after a small amount of food may help. Avoid adding syrups, flavoured creamers, or large amounts of milk, which can add a significant number of hidden calories.

Protein Shakes

On weight loss medication, patients often eat considerably less than before. This can make it harder to meet daily protein requirements, particularly as the medication reduces overall appetite. Adequate protein intake is important for preserving muscle mass during weight loss.

A low-sugar, high-protein shake can be a practical way to maintain protein intake on days when eating feels difficult. Look for options with minimal added sugar and a straightforward ingredient list. These are best used to supplement a balanced diet rather than replace meals entirely.

Drinks to Limit or Avoid

Some drinks are worth reducing significantly during weight loss treatment:

• Alcohol: Alcohol is high in calories, lowers inhibitions around food choices, and can worsen side effects such as nausea and dizziness. It also interacts poorly with the reduced calorie intake that typically accompanies treatment, increasing the risk of hypoglycaemia in patients with diabetes. Limiting alcohol is strongly advisable.
• Sugary fizzy drinks: These deliver a high calorie load with no nutritional value and no satiety benefit, which directly conflicts with the goals of weight loss treatment.
• Fruit juices: Even 100 percent fruit juice is high in natural sugars and calories. Eating whole fruit is a significantly better option as it provides fibre and triggers satiety more effectively.
• Sweetened coffees and teas: Large flavoured coffees from high street chains can contain several hundred calories per serving. These are worth checking and replacing with lower-calorie alternatives where possible.

A Simple Guide to the Best and Worst Choices

Small Choices, Meaningful Differences

Weight loss medication does a significant amount of work in reducing appetite and supporting a calorie deficit. But the lifestyle choices you make around treatment, including what you drink every day, contribute to how effective that treatment ultimately is.

Prioritising hydration, avoiding liquid calories where possible, and being mindful of alcohol are straightforward steps that require no dramatic changes to your routine but can meaningfully support your results.
