This guy has tracked every meal he's eaten for the last 4 years - and he was shocked to see just how much he spends on food

Jamie Welsted is just a normal guy - except that he has diligently tracked every meal (and beverage) that he's consumed over the past four years.

But make no mistake: This is not Weight Watchers.

The 41-year-old graphic designer from Buffalo, New York, started the project when his coworkers were confused about how much food he was able to eat without seeming to gain any weight.

"I've been blessed with a fast metabolism," Welsted told Business Insider. "I'm a skinny guy - I eat whatever I want."

So he started chronicling his daily intake, including the location, dishes, and cost of each of his meals and beverages. Originally just a simple Google Doc, the project quickly morphed into a Tumblr page that he updates each day, and sometimes even on the go; it takes him about 30 minutes to an hour.

Over the years, he's collected over 5,500 followers of his culinary journey, along with an impressive data log of his (highly) caloric intake and expenses.

He calls his blog "My Terrible Diet." We talked to him to see what he's learned from the project.
