How are SlimFast meal replacement shakes typically used?
Meal replacement products are commonly used as part of a structured, calorie-controlled plan. Follow the directions on the pack for your chosen product and include balanced meals and adequate fluids across the day.
What’s the difference between ready-to-drink and powder shakes?
Ready-to-drink bottles are pre-mixed for convenience, while powders are mixed at home as directed. Your choice often comes down to routine, storage, and flavour preference.
Are SlimFast products suitable if I have a medical condition or take medicines?
If you have a long-term health condition (including diabetes), are under 18, are pregnant or breastfeeding, or take regular medicines, speak to a pharmacist or GP before using meal replacement products.
How do I choose a SlimFast flavour and format?
If you’re starting out, many people try one ready-to-drink flavour for busy days and one powder flavour for home. Bars can be helpful when you want a portioned snack option.
Do SlimFast shakes or bars contain allergens or sweeteners?
Some products may contain common allergens (such as milk and soya) and may include sweeteners. Always check the ingredients and nutrition information on the product page and packaging to confirm suitability.
When should I ask for advice about weight management?
Seek advice if you’re unsure which option is appropriate, if you have symptoms affecting appetite or weight, or if your plan feels difficult to maintain. A pharmacist or GP can help you choose a safer approach for your circumstances.
Safety note: SlimFast products are foods and are not medicines. They do not replace medical assessment or treatment. If you feel unwell, have persistent symptoms, or have an eating disorder history, speak to a pharmacist or GP before use and follow label directions carefully.
