An incrementally-sized dishware system and method for weight management gradually modifies food portion consumption behavior to provide healthier eating habits. The incrementally-sized dishware system and method includes a plurality of incrementally-sized plates having successively differentiated plate surface areas. Each of the incrementally-sized plate surface areas is successively different by an increment to modify food portion delivery to a user. When utilizing the incrementally-sized dishware system and method a user selects a starting plate surface area based on a combination of weight management factors, and over time successively shifts to plates having smaller/larger plate surface areas. Interval changes between the dishes of the incrementally-sized dishware system and method adjust the amount of food consumed and rate of weight loss over time. Children using the incrementally-sized dishware system and method learn to recognize an appropriate meal size for their body size and weight, and establish healthy eating habits that carry into adulthood.
