Understanding Weight Loss Treatments

Losing weight is a journey that requires a holistic approach—balancing calories consumed with calories burned. While diet and exercise are essential, medical treatments can provide an important boost. Our portfolio includes clinically proven options like Mounjaro, Wegovy, Mysimba, Saxenda, Orlistat, and Alli.

Mounjaro

Mounjaro is the latest of the weight-loss injection pens and has shown the highest effectiveness in clinical trials, with an average body-weight loss of ~22.5%. This compares to ~10% with Saxenda, and ~15% with Wegovy and Ozempic.

Active ingredient: Tirzepatide.

  • Start at the lowest dose and titrate up to minimise side effects.
  • Starting dose: 2.5 mg; highest maintenance dose: 15 mg.
  • Administration: once weekly injection.

Wegovy

A once-weekly weight-loss injection from Novo Nordisk that helps regulate appetite and metabolism. Clinically proven for sustainable weight management.

Mysimba

Combines naltrexone and bupropion. Most effective with a low-calorie diet and regular exercise; acts on brain pathways linked to appetite, energy balance, and cravings.

Saxenda

An injectable prescription medicine (liraglutide) for adults with obesity or weight-related conditions. Mimics a natural hormone to help regulate appetite and food intake—used when lifestyle changes alone aren’t enough.

Orlistat

Blocks a portion of dietary fat from being absorbed so it passes undigested. Best used alongside a reduced-calorie diet, exercise, and behaviour change.

Alli (60mg)

The over-the-counter, lower-dose version of Orlistat. Helps prevent fat absorption and supports a low-fat, reduced-calorie diet for overweight adults.

Ozempic

Ozempic is widely known but isn’t licensed for weight loss in the UK—it’s licensed for diabetes treatment. Many doctors do prescribe it off-licence for weight management and it can be effective.

Active ingredient: Semaglutide (same as Wegovy).

Because Ozempic is primarily used in diabetes, we choose not to prescribe it in order to avoid impacting supply for diabetic patients.
