SlimFast: Frequently Asked Questions
Is SlimFast good for you?
SlimFast shakes are high in protein, a source of fibre, and provide 23 vitamins and minerals with no added sugar, as part of a calorie-controlled diet. As with any diet, always follow the pack instructions and speak to a doctor or pharmacist if you're unsure whether it's right for you.
Does SlimFast work?
SlimFast shakes are designed to support weight loss as part of a calorie-controlled diet, by replacing higher-calorie meals with a portion- and calorie-controlled alternative. Results depend on sticking to the plan alongside your one balanced meal and snacks.
Can I have SlimFast if I'm pregnant, breastfeeding or have a medical condition?
SlimFast products are intended to supplement the diet and should not replace a balanced and varied diet or a healthy lifestyle. If you're under 18, pregnant, breastfeeding, have a medical condition, or want to lose more than 20% of your body weight, speak to your doctor or pharmacist before starting.
Is SlimFast suitable for vegans?
SlimFast shakes are suitable for vegetarians, but not for vegans, as they contain milk-derived ingredients — including skimmed milk powder, whey powder, milk protein, and soya bean oil powder made with milk.
