Formula 4.3 of 5 × category evidence 2.5 of 2.5 ÷ 2.5: the science counts only as far as this product is like the ones studied. Meal replacements are among the most studied dietary approaches for weight management: a systematic review and meta-analysis of randomised trials found greater weight reduction at one year than food-based diets (Astbury et al., Obesity Reviews, 2019). Each 50 g shake gives 200 kcal with 19 g protein and 3 g fibre, as shown on the listing, for use in place of one meal. This does not promise any result.
