How Bliss Works - Clinically-Guided Weight Loss
A smarter approach to weight loss: prescription treatment from UK-registered clinicians, paired with 1:1 nutrition coaching and support at every step. Real experts offering real guidance for real change you can maintain.
How much weight could you lose?
Clinical trials for prescription weight loss medication show significant, sustained results for eligible adults. On average, patients in published studies lost between 14% and 21% of their body weight over 12 to 18 months — that's the equivalent of 12–18kg for someone who weighs 85kg.
Your individual results will depend on your starting weight, the treatment your clinician recommends, and how closely you follow your programme. Use the calculator below to see an estimate based on your details.
BMI is a predictive indicator of weight range. For a more in-depth understanding of your weight and available medical solutions, start an online consultation with a bliss doctor today.
Your Weight Loss Timeline
See what could be possible in just 12 months with Bliss. A year of expert-led support, a lifetime of healthier habits.
Kickstart your journey
Complete a short online health assessment — it takes around five minutes. A UK-registered Bliss clinician reviews your answers, confirms your eligibility and recommends a weight loss treatment plan tailored to your BMI and health profile. Your first prescription is dispensed by our GPhC-registered pharmacy and delivered directly to your door.
Healthy, sustainable weight loss
Your treatment dose increases gradually — this is intentional. It gives your body time to adjust and helps minimise side effects. Most Bliss members begin to see consistent, measurable weight loss within 4–8 weeks. Your Bliss dietitian keeps your nutrition on track throughout, ensuring your weight loss is fat loss — not muscle.
Long-term results
For eligible members, the goal is sustained, clinically meaningful weight loss — typically 10–20% of body weight over 12 months. Unlike fad diets, a medically supervised weight loss programme is designed to produce results that last. Ongoing Bliss support ensures your progress is maintained, not reversed.
