The bar graph illustrates the frequency with which Americans dined at fast food restaurants in 2003, 2006, and 2013, with figures presented in percentages.

Overall, the most common frequencies were once a week and once or twice a month, while the proportions of those dining daily or never were minimal. A notable trend is the significant increase in the share of individuals eating at fast food outlets on a monthly basis.

In 2003, approximately 31% of Americans ate fast food once a week, rising slightly to around 33% in 2006 before falling to 28% in 2013. Meanwhile, the proportion of those dining once or twice a month started at 30%, dropped to 25% in 2006, and then peaked at 33% in 2013. The share of people eating fast food several times a week remained lower, fluctuating around 15–20% across the years.

Smaller proportions were recorded for those eating a few times a year, daily, or never. Individuals who dined at fast food restaurants only a few times a year made up about 13% in 2003, increasing slightly to 15% in 2006 and remaining stable in 2013. The figures for those eating daily or never were around 5% initially, with both experiencing slight declines over time.
