A novel dough-like mixture made using cellulose and hydrocolloid gums that can be used as a basis for forming a variety of low-calorie foods is disclosed. Methods for producing low-calorie and reduced-starch donuts, fillings, cookies, breads, and many other food products using this dough are also described. Erythritol-based reduced-sugar confectionery items and methods for their production and application, including use in reduced-calorie sweet-tasting bakery goods, are also disclosed. Many of the disclosed foods are low enough in caloric value to be termed "recreational solid foods," with experiments showing that even ad libitum eating of them results in weight loss.
