- Pick the format you’ll stick with: ready-to-drink for convenience, powder for flexibility/value, bars for portability, tablets/sachets for simplicity.
- Check label directions before you start: timing with meals, serving size, and any guidance on duration of use.
- Review suitability: take extra care if you take medicines, have a long-term condition, or have absorption/dietary concerns.
- Start small, then scale: trial a smaller pack first, then consider value packs once it fits your routine.
- Keep expectations realistic: results vary; these products support a plan rather than replace healthy eating and activity.

FAQs
What’s the difference between meal replacements and slimming supplements?
Meal replacements are intended to replace a meal as part of a structured plan. Supplement-style products (such as fat binders or carb blockers) are used alongside meals and lifestyle changes. Always follow label directions and do not exceed the stated dose.
How do I use meal replacement shakes safely?
Use exactly as directed on the label, including serving size and how many meals they’re intended to replace (if any). Keep your other meals balanced and stay hydrated. If you’re unsure what’s appropriate, ask a pharmacist or your GP.
Are fat binders and carb blockers suitable for everyone?
No. They may be unsuitable if you’re under 18, pregnant or breastfeeding, have certain medical conditions, or take regular medicines. Check the label carefully and seek advice if you’re unsure.
Can I take slimming products with prescription medicines?
It depends on the product and your medicines. Some products may affect absorption or timing. If you take prescription medicines, ask a pharmacist to check suitability and follow any spacing instructions on the label.
Will these products guarantee weight loss?
No. Results vary, and no over-the-counter product can guarantee weight loss. These options are best viewed as support tools alongside a calorie-controlled diet, regular activity and realistic goals.
How do I choose between ready-to-drink shakes, powder and bars?
Ready-to-drink shakes suit busy days, powders offer flexibility and can be better value, and bars are convenient when you need something portable. Choose the format that best fits your schedule so you can follow a consistent plan.

Important: Weight management products are not suitable for everyone and should be used as directed. Do not use if you are pregnant or breastfeeding, and seek advice before use if you are under 18, have a long-term condition, take regular medicines, or have a history of eating disorders. Stop use if you feel unwell and contact a pharmacist, your GP, or NHS 111 for advice.
