While the judgments would involve starvation, the prophet Hosea does not emphasize that point in chapter 9. Rather, he emphasizes that there won’t be enough food to use to offer God or to hold feasts to God:

Threshing floor and wine vat shall not feed them,
and the new wine shall fail them.
They shall not remain in the land of the Lord,
but Ephraim shall return to Egypt,
and they shall eat unclean food in Assyria.

They shall not pour drink offerings of wine to the Lord,
and their sacrifices shall not please him.
It shall be like mourners’ bread to them;
all who eat of it shall be defiled;
for their bread shall be for their hunger only;
it shall not come to the house of the Lord.

What will you do on the day of the appointed festival,
and on the day of the feast of the Lord?
For behold, they are going away from destruction;
but Egypt shall gather them;
Memphis shall bury them.
Nettles shall possess their precious things of silver;
thorns shall be in their tents.

This punishment fits the crime. At one time Israel was blessed with a bountiful surplus. According to chapter 10:

Israel is a luxuriant vine
that yields its fruit.
The more his fruit increased,
the more altars he built;
as his country improved,
he improved his pillars.

Thus, God blessed Israel, and Israel used that blessing to bless other gods. Now the blessing will be removed and scarcity will end the possibility of worship.
