The Process
How Our Medical Weight Loss Programme Works
Our doctor-led weight loss programme at London Blood Tests follows a structured, medical approach designed to deliver safe, measurable, and sustainable results. Every stage is supervised by healthcare professionals to ensure your body responds correctly and your progress remains steady and healthy.
Initial GP Consultation & Health Evaluation
Your journey begins with a full medical consultation with one of our experienced GPs. This session includes a detailed health and medical history review, discussion of symptoms and weight concerns, and assessment of underlying causes that may affect weight (hormonal, metabolic, nutritional).
The aim is to understand your body, identify potential barriers, and create a safe plan tailored specifically to you.
Advanced Blood Testing & Biomarker Review
We perform targeted blood tests to assess key markers linked to weight gain and metabolism, such as:
- Thyroid function
- Blood glucose and insulin
- Cortisol
- Vitamin deficiencies
- Liver and kidney function
- Hormonal balance
Understanding these biomarkers allows us to design a treatment plan that works for your physiology rather than relying on generic approaches.
Personalised Treatment Plan
Based on your results, our medical team creates a bespoke weight loss protocol. This may include:
- Clinically approved weight loss injections
- Peptide therapy to boost fat metabolism, regulate appetite, and improve energy balance
- Supplement recommendations based on deficiencies
- Lifestyle and nutrition guidance aligned with your medical results
Your plan is designed to be safe, structured, and fully medically supervised.
Weekly or Monthly Injections / Peptide Administration
Depending on your programme, you will receive:
- Weekly injections administered by our medical team or provided for self-administration (where appropriate)
- Daily or cyclical peptide therapy, tailored for fat loss, muscle preservation, or metabolic support
These therapies work on deeper biological pathways, helping regulate appetite, stabilise blood sugar, and enhance fat metabolism.
Monthly Assessment, Tracking & Adjustments
Every month, you will have a progress review, which includes:
- Weight tracking
- Body composition analysis
- Symptom monitoring
- Side-effect check
- Blood pressure or relevant vitals
- Review of appetite, energy, and mood
Your GP or clinician will adjust dosages, add peptides if needed, or modify your lifestyle plan to ensure continued progress.
Continuous Medical Monitoring
Throughout your programme, our team monitors your response to treatment. This includes:
- Regular communication
- Safety checks
- Adjustment of medications/peptides based on results
- Ensuring your progress is healthy and sustainable
You are never left to "figure it out alone", all changes are guided by a medical professional.
Long-Term Maintenance & Support
Once your goal is achieved, we help you transition into a maintenance phase to prevent rebound weight gain. This may include lighter peptide cycles, lifestyle optimisation, nutritional and metabolic support, and periodic check-ins or blood tests.
Our focus is not just helping you lose weight, but keeping it off long term.

Safe, Doctor-Led Weight Loss
Every step is overseen by medical professionals. Your GP evaluates your health, monitors progress, and adjusts your plan based on real biomarkers, ensuring your weight loss is safe, controlled, and medically appropriate.
Personalised Plan Based on Bloodwork
We don't guess, we test. Your treatment plan is created using your hormonal, metabolic and nutritional markers, providing a customised approach that targets the exact causes of weight gain.
Effective Weight Loss Injections
We use clinically approved weight loss injections to help regulate appetite, stabilise blood sugar, and increase fat metabolism. This enhances results while reducing cravings and overeating.
Peptide Therapy for Metabolic Support
Peptides support fat burning, hormonal balance, insulin sensitivity, muscle preservation, and better sleep and energy. This makes weight loss more effective and easier to maintain long term.
Monthly Tracking & Adjustments
You're monitored closely with monthly reviews, body composition tracking, symptom and side-effect checks, dose adjustments, and lifestyle recommendations. Continuous monitoring ensures steady progress.
Faster, More Sustainable Results
By combining injections, peptides, testing, and lifestyle guidance, our programme accelerates fat loss while maintaining muscle mass, improving long-term success.
Reduces the Risk of Weight Regain
Once you reach your goal, we help you stabilise your results with lighter peptide cycles, maintenance guidelines, periodic check-ins, and continued metabolic support. You don't simply lose weight, you learn to maintain it safely.
Ideal for Stubborn or Hormone-Linked Weight
Our programme is particularly effective for weight gain linked to thyroid issues, insulin resistance, post-pregnancy changes, perimenopause or menopause, and chronic stress or cortisol imbalance. Because we treat the root cause, not just the symptoms.
