Common questions
Can’t find your answer? Get in touch and we’ll help.
What makes STW different from other meal replacements?
We’re the only meal replacement brand certified as a Medical Device under UK regulations — not just a food product. Our range of 60+ products across 7 categories means you’ll never get diet fatigue. And at from £1.85 per meal, we’re significantly more affordable than consultant-based alternatives.
Do I need a consultant or appointments?
No. You buy directly online, choose your own plan, and start immediately. No appointments, no waiting lists, no ongoing consultant fees.
Which plan should I choose?
Our Total plan (800 kcal) is most popular for maximum results. Everyday (1,000 kcal) balances replacements with one normal meal. Active (1,200 kcal) suits those who exercise regularly. Not sure? Start with Everyday — you can adjust any time.
Is STW suitable for people with type 2 diabetes?
Yes. Our products are Medical Device certified and designed to support very low calorie and low calorie diet plans, which research shows can help with type 2 diabetes management. Always consult your GP before starting a new diet plan.
Can I use STW alongside GLP-1 medications?
Yes. We’ve developed specific nutrition plans to support GLP-1 medication users (Ozempic, Wegovy, Mounjaro) with the right balance of protein, vitamins, and minerals.
