Special dinnerware may be path to weight loss BOULDER, Colo., Feb. 8 (UPI) -- Many may have too much on their plate, but a new kind of dinnerware with circles painted for portion size may lead to weight loss, its Colorado creator says. Sheila Kemper Dietrich of Boulder, Colo., said she used science -- or the research on portion size, plates, glasses and color -- to create her dinnerware, the Boulder Daily Camera reported. Dietrich said with ancestors as hunter gathers most people will eat what's put before them, so she made dinnerware to fool Mother Nature by featuring circles of different sizes on the plate -- one for starch, one for vegetables, one for protein and one for sauce -- made to look like part of the plate design and suitable for company, the newspaper said. Dietrich, who said she lost 50 pounds using the dinnerware herself, said the circles provide a visual cue for portion sizes recommended by the U.S. Department of Agriculture. The serving sizes have a goal of 1,500 calories a day. The dinnerware is done in gray and slate green or shades of blue, cream and plum, because studies show it's the warm colors of red and yellow that stimulate appetite, Dietrich said. Soon stemware will be available with circles etched into the design indicates 4- and 6-ounce portions, Dietrich said. A four-piece set retails for $49.95 at livligahome.com.
