Data and formulae used for the questions are as realistic as possible and are based on actual nutritional information found on foods, exercise and BMR/BMI data and formulae are taken from the Compendium of Physical Activities and from Diabetes and Cancer charities.

The initial questions would be particularly suitable for an S3/S4 middle-higher ability Maths class, and may be used as part of a cross-curricular project with Home Economics/PE/Science and Guidance departments etc. Later questions would be particularly useful for assisting GCSE/National 5 Maths classes with exam revision.
