Why lifestyle changes still matter
Medicines such as Wegovy® and Mounjaro® can be highly effective, but they are not a “standalone” solution. In all the large medical studies, patients were advised to follow a reduced-calorie diet and increase their physical activity. Those who made these changes achieved the best results. Healthy lifestyle habits also make it easier to keep the weight off once treatment finishes, supporting long-term success.
Healthy eating habits that support weight loss
- Eat protein with every meal: Protein is important for protecting muscle while your body burns fat. It also helps keep you satisfied between meals. Good sources include lean meats, fish, eggs, beans, tofu, lentils, and yoghurt.
- Choose more fibre-rich foods: Vegetables, beans, lentils, whole grains, nuts, and seeds are filling, support healthy digestion, and help maintain steady blood sugar. Fibre also plays an important role in reducing cholesterol.
- Follow a Mediterranean-style diet: This way of eating is rich in vegetables, fruits, olive oil, whole grains, beans, nuts, and lean proteins such as fish and chicken. It has been shown in many studies to lower the risk of heart disease and high blood pressure, both of which are more common in people living with obesity.
- Stay hydrated: Drinking enough water supports digestion and reduces the chance of constipation, which can sometimes happen when starting treatment. Aim for regular sips of water throughout the day.
- Smaller, mindful portions: GLP-1 medicines slow digestion, which means you may feel full with less food. Eating slowly and paying attention to your body’s signals can help you stop when satisfied, reducing discomfort and avoiding overeating.
- Limit processed foods and sugary drinks: Foods high in added sugar, salt, or unhealthy fats can undermine progress and increase health risks. Replacing them with healthier choices supports both weight loss and heart health.
Extra health benefits
Adopting these eating habits alongside GLP-1 medicines does more than just reduce body weight:
- Lowers blood pressure and eases strain on the heart.
- Improves cholesterol levels, supporting healthier arteries.
- Reduces blood sugar and the risk of developing type 2 diabetes.
- Protects long-term health, reducing the risk of heart attacks, strokes, and other weight-related conditions.
