The present invention provides an aqueous liquid or spoonable edible composition comprising at least 1% wt protein and from 0.1 to 5% wt of a biopolymer thickening agent which is not denatured or hydrolysed between pH 2 and 4, and wherein the composition has a gastric viscosity at 0.1 s.sup.-1 and 37.degree. C. of at least 20 Pa.s and further wherein the gastric viscosity is greater than the viscosity of the composition. The compositions of the invention have good satiety effects and are beneficial for use in weight control plans and may be used for the prevention and/or treatment of being overweight or obese. The edible composition may be a food composition intended for use in a weight loss or weight control plan such as a meal replacer food product.
