This theory is derived from ideas gathered from a blog by Mr Mark Matson. It is called the HariRama.com Lemma: If eating calories means you get energy then does eating more costly food mean you are getting more energy? Calories: 1 Calorie = enough energy to heat 1 litre of water from 20°C to 21°C Calories = energy ⭌ money According to the Hari Rama¹: Joules = energy * time = watts * seconds Joules = energy = money Therefor: If in the nine-teen 50s we ate a one-cent pie and in the year 2017 we eat a $3.50 pie, given inflation in to account, - when we eat costly food are we taking in more than the necessary joules?
