Weight loss tablets work by blocking the absorption of some of the fat in your diet. As a result, your body absorbs fewer calories from the fat you eat, which can help you lose weight over time. Injectable GLP-1 treatments, like Wegovy® and Mounjaro®, are more effective as they help control your appetite. They mimic a natural hormone in your body called GLP-1, which signals to your brain that you’re full and should stop eating. By increasing this signal, GLP-1s can regulate your blood sugar and keep you feeling fuller for longer. Both oral and injectable treatments are designed to be used as part of a weight loss plan that includes a healthy diet and regular exercise.

Injectable GLP-1s treatments can be six times more effective than diet and exercise alone, and nearly double your weight loss compared to other popular medications like weight loss tablets. Mounjaro® stands out as the most effective dual acting GIP + GLP-1. Studies show that pairing the highest dose with healthy lifestyle changes leads to an average weight loss of up to 20.9% in 36 weeks and up to 25.3% in 88 weeks. In comparison, Wegovy® users report an average weight loss of up to 15% after a year.

Oral weight loss treatments, like orlistat, are clinically proven to help you lose 50% more weight than just dieting alone. In clinical trials, almost twice as many people lost 10% or more of their body weight in one year when taking orlistat, compared to those who were dieting without treatment. Alli is designed to be used alongside a support programme. For every 2kg your efforts help you lose, Alli can help you lose 1kg more. It works by blocking 25% of the fat you eat from being absorbed, so it makes your healthy choices even healthier.

Mounjaro® and Wegovy® are injectable pens you use once a week. They’re easy to use and give you the right dose without needing measurements or syringes. You can inject them into your arm, leg, or abdomen. The pens have a small, fine needle for a nearly painless injection just under the skin surface. They come with clear instructions and links to video demonstrations.

Take one pill with a drink at each main meal that contains fat. You should take Orlistat (Alli®) up to three times a day alongside a reduced-calorie diet. Each time you take it, your meal should contain no more than around 30% of calories from fat.

GLP-1s, or glucagon-like peptide-1 receptor agonists, are among the most effective medications available for weight loss. They work by mimicking the effects of a natural hormone called GLP-1 in your body. This hormone helps regulate your appetite, slows down digestion, and promotes a feeling of fullness after eating. By stimulating GLP-1 receptors, these medications can help you feel more satisfied with smaller portions of food, leading to reduced calorie intake and gradual weight loss over time. They are a main ingredient in injectable pens like Mounjaro® and Wegovy®, which are often prescribed alongside a balanced diet and regular exercise to achieve the most effective results in managing weight.
