How does the change in rhythm in the fourth stanza of “Hunger” contribute to the poem’s meaning?

In Emily Dickinson's 'Hunger' the word itself along with the word food serves as a host of metaphors.

Explanation:

The poem is in 5 stanzas and the 4th stanza represents a turnaround in the narrative of the poem.

It starts with the availability of food that the narrator has never felt before and as they draw the food near they describe the hunger they have faced till then.

In the fourth stanza the rhythm changes as now the narrator starts narrating how being in plenty has also hurt them. That having aplenty is as bad as having none is the running theme that becomes clear here.
