Booker stopped living on the equivalent of food stamps Tuesday at midnight.

He says it was difficult to live on about $4 a day worth of food and give up caffeine for a week.

Booker says he accomplished his goal of starting a national conversation about food stamps.

The idea started when Booker challenged a Twitter user that the two spend the week living on food stamps.

The woman also spent a week on food stamps, but not during the same time as Booker.

Booker said Tuesday that he accomplished his goal of greater awareness and whether the woman took on the challenge was "not as important."
