Update on my life:

Chocolate intake: sky-high
Food intake: down

Therefore by the principles of mathematical addition and subtraction,

Weight: Constant (assuming constant Marginal Propensity to Convert food into energy and also constant Marginal Propensity to Shit, and that chocolate and food are substitutable i.e. cross-elasticity more than 0)

Also, assuming 2-sector economy, I am helping the country raise its aggregate expenditure by consuming increasing output of chocolate. By ensuring that output does not exceed money supply, i.e. MV=PY, I am critical in preventing instability of economy.

Ah yes. Worthy member of society am I. I have found my purpose in life, and that is to consume chocolate.
