I have neither included transport cost nor sales nor waste. If you live in the UK you might immediately know what including these in that completely unrealistic article would mean. (1) You have to go to one of the superstores to get these prices - Tesco Express, Sainsbury's Local e.a. almost never store the cheapest goods and normally mark up all other goods by a substantial amount (30%+). Next cheapest goods on the list are often 100%+ more than the prices used in the article (that's the superstore price of course) - most extreme (from my own experience) with rice - the cheapest rice you most likely find in a Tesco Express is £4+ vs. 40p quoted, that's 1000%. (2) Getting to a superstore can be rather costly - assuming about £3.2 for bus tickets (that's £6.4 per week uups just doubled your weekly budget by only adding the transport cost) - you might alternatively walk about 10-16 miles each time (both ways, can be more if you live on the countryside) - guess that's the healthy part of that diet - walking 32 miles each week (you should than of course also adjust you calories / fat / vitamin intake which gets us to about e.g. £12 actual vs £7 and 12 hours spent walking). (3) To use sales most effectively you have to have a budget to vary your diet, buy larger quantities when available etc - neither of this is possible in the constraints of this assumption - hence I also did not use sales prices.
