Reviews of the Almased shake diet are generally positive. Of nearly 1,700 Amazon reviews as of 2015, over half the customers give the product five stars and nearly 20 percent give it four stars, citing its efficacy in feeling full.
Reviewers posting on GNC.com and Amazon.com do not mention experiencing side effects. The main complaints from dissatisfied customers are about the "chalky" taste. They suggested that the taste could be improved by adding honey, cinnamon or vanilla and by drinking the shake immediately. Customers praised the diet for helping them to eat less and reported a weight loss ranging from 6 to 36 pounds after using the product.
