Add a Feeding sub-rule to Population:

Whenever the Hegemonist increases the Stocks of Commodities of a Country due to posting a Market Position, e shall reduce the Stock of Food (according to that Country race) of said Country by 5% (rounding the reduction up to the next integer. Ex.: 1.01 becomes 2) of the combined Population of all Terirtories that Country controls.

If the Hegemonist is unable to reduce a Country’s Stock of Food, because that Country lacks enough food to allow that, the Hegemonist shall {Make a Post} with subject “Starvation Warning: Country X #NNN”, where “X” is the name of the Country lacking food and “NNN” is a sequential number starting at 001 for each Country. The #NNN starving counter for a Country shall be reset to 001 every time the Hegemonist is able to reduce that Country’s Stock of Food in the manner of this rule.

Whenever the Hegemonist posts a “Starvation Warning: Country X #NNN” with a #NNN greater than 002, the Hegemonist shall reduce the population of all Territories controlled by that Country by one tenth (rounding the reduction up to the next integer. Ex.: 1.01 becomes 2).

Notice that Population reduction will only occur upon Starvation #003 or more, that means the third coinsecutive day with the country laccking food. So, you overpulated countries will only have to bother acquring food once every 3 days.
