Last July, Cunningham set out to eat one Chipotle meal per day for one full year, plus one extra for leap year. He told INSIDER that he was "already eating Chipotle 3-5 times a week before this diet," so choosing Chipotle seemed obvious.
His goal was to bulk up initially, and then slim down for summer. He started at 156 pounds and 12% body fat, and his goal was to reach 170 pounds at about 14% body fat, then cut down to 150 pounds at 9% body fat for the summer.
To bulk up, he'd order "anything and everything," which usually meant double meat, guac, rice, beans, and salsa.
And when he wanted to slim down for the summer, he'd get a chicken or steak bowl with veggies.

He planned ahead before traveling so that he'd always have a Chipotle meal ready.
Cunningham told INSIDER that he believes achieving your body goals is "80% diet, 20% working out."
He works out 4-5 times a week for about an hour.
He counts all his calories, grams of protein, carbs, and fat. He follows the "if it hits your macros" belief, meaning you can eat anything as long as it's measured correctly and fits in his guidelines.

And by day 317, he successfully cut down to 146 lbs and 8.7% body fat.
When he's not eating Chipotle, he likes snacking on non-fat Greek yogurt with berries and granola. For dinner, he'll often eat a double cheeseburger, and will weigh the burger to make sure it fits within his guidelines.
Cunningham said that once the year is over next month, he'll continue to eat Chipotle regularly.
