This year, Aldi’s Slim & Trim took out Canstar’s 2026 Most Satisfied Customers Award for Weight Loss Shakes, with Aussies rating the brand the highest across the categories that drive customer satisfaction.
Our review compares weight loss shake brands on customer satisfaction, so you can find out what other Aussies think about the compared brands before you go ahead with a purchase. Think of it as like asking hundreds of your closest mates which weight loss shake brand they think is best!
Canstar Blue surveyed 448 Australians for their feedback on the weight loss shake brand(s) they’ve purchased and consumed in the last 12 months.
Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.
