Photos: Millennials' Food Habits By State

Millennials are spending big money on guilty pleasures they are probably not telling their personal trainers about, according to new data from budgeting app Level Money.

First up: alcohol. Average annual spending by Millennials varies by state — and some residents are a whole lot boozier than others.

Many Millennials are breaking their healthy habits and binging on Whoppers and french fries. And McDonald's is their restaurant chain of choice.

Millennials also like to splurge on lattes and Red Bulls. The most popular place to fuel up on caffeine? Starbucks. Spending averages are also high at the chain because its gift cards are such popular purchases. (CNN Money)
