Teammates,
Would like to offer the following definitions, which perhaps I can also propose as a general template.
Affordable -- That the costs incurring in diet modification remain within each CI team members' budgets and does not necessarily impinge upon other discretionary lifestyle-related expenses.
Explanation. We cannot assume that the changes in diet will result in decreased or constant cost. Certainly if we explore 'healthier' options, there is reason to believe costs may go up (absent other approaches such as 'grow it yourself'), so what constitutes an acceptable cost increase? I think the above wording leaves that to the individual -- what each of us can tolerate.
Measures of 'Affordability' -- CI team members will establish initial absolute or relative ceilings for monthly expenditures for food. An 'absolute' ceiling might be 'no more than an increase of $100 spent per month' while a 'relative' ceiling might be 'no more than an increase of 5% per month on food.' Team members may change their ceiling numbers during the course of the inquiry.
As cost figures are a private matter, CI team members need only share the ceiling and yes/no whether or not the measures have been successfully met during experiments. CI team members may elect to release further data on a strictly voluntary basis, and such data shall not be disseminated outside the CI team.
