Problem - Creatively Addressed with Design

Thanks to Andrea Learned for this posting. Dieting can be addressed with portion control. How do you provide portion control easily? Design some bowls that nest, are attractive, and measure portions. Hence Mesu. Wonderful design! PS - I like the possible extension for these already mentioned in the comments; the capability to teach youngsters fractions. What was I saying about idea creation the other day? This is a good example.
