 The winning dish is determined by a panel of certified nutritionists (as of the 2014–15 season, Stephanie Clarke and Willow Jarosh, both registered dietitians with master's degrees in science) and the family featured in the given episode.Each dish is rated on a categorical score from 1 to 10, based on the total percentage of total fat, saturated fat, cholesterol, sugar and sodium content reduced in the "rehabbed" recipe in comparison to the original; the ease and length of preparation between the two "rehabbed" recipes (both categories are determined by the nutritionist panel); and the taste of the healthier dish (which is determined by the family).These scores are combined into the maximum cumulative score of 30, determining the chef with the episode's winning recipe.
