Disclosed herein are methods of inducing satiety by providing microalgae-based foods. In some embodiments, microalgal biomass contains high levels of dietary fiber and/or digestible crude protein and/or low saturation triglyceride oil. Homogenization methods to liberate free oil and fiber are disclosed for enhancing the feeling of satiety in a human, thereby reducing caloric intake. The provision of such materials to a human have the further benefit of providing heart-healthy microalgae-based ingredients while achieving levels of satiety sufficient to reduce further caloric intake.
