Reduced calorie potato chips, and other low moisture fat-containing foods having less waxiness and improved flavor display are dislosed. These benefits are typically obtained by applying to the surface of the potato chip, or other food, fat compositions having certain thixotropic areas that correlate to reduced waxiness impressions. These fat compositions comprise a nondigestible fat component, and optionally a digestible triglyceride fat or oil. The nondigestible fat component comprises a nondigestible oil and preferably low levels of certain solid polyol fatty acid polyesters having ester groups comprising combinations of unsaturated (C.sub.12 or higher) and/or short chain (C.sub.2 -C.sub.12) saturated fatty acid radicals and long chain (C.sub.20 or higher) saturated fatty acid radicals. The solid polyol polyesters bind the liquid oils and thus control or prevent passive oil loss, even at relatively low levels.
