The Five Guys Diet

June 17, 2013


I’ve been saying for a couple months now that I’m going to be Five Guys’ version of “Jared” — you know, the guy who lost weight by eating a lot of Subway sandwiches.

Here’s why: Five out of the last six times that I’ve had Five Guys for lunch, I’ve lost weight when I got on the scale the next morning.


Let me explain how and why it works.

The Five Guys Diet

What I eat: This happens when I have Five Guys for lunch. I order a regular meal, which is typically a Little Cheeseburger with my favorite toppings, a Little Fries and a small drink if I’m eating at the restaurant. If I’m bringing the food home, I skip the drink and just have water at the house.

What happens: A Little Cheeseburger at Five Guys isn’t very little, and the Little Fries turn into an enormous serving of fries because they always scoop an extra serving into the bag. It’s a lot of food and it fills me up for the rest of the day.

I eat this at about noon or 1 pm and I literally don’t eat again the rest of the day. It’s that filling.

Sometimes I work out in the evening, sometimes not. Either way, by skipping dinner I somehow end up being full while eating less than a full day’s worth of calories … and I lose weight.

How much I lose: Some days I’ve lost as much as a full pound. Some days just .2 or .4 of a pound. But it’s still weight loss, no matter the amount.

Requirement: You have to eat breakfast first. Read on for why….

The One Time It Didn’t Work

As I said, this has happened five of the past six times that I’ve had Five Guys. The one time it didn’t happen? Well, I didn’t exactly follow the above plan.

I skipped breakfast that day and decided to try to make Five Guys my only meal of the whole day. Didn’t work. Since I didn’t have the breakfast calories in me, the Five Guys lunch didn’t fill me up. I got hungry and ended up having a late dinner (about 8 pm) and actually gained a pound that day.

So the lesson is obvious: You gotta have breakfast.

That’s it. The Five Guys Diet. If anyone from the restaurant chain happens on this and wants to get in touch, I’m easy to reach. 🙂

    I just googled this subject and your story popped up. Soooo, what you did here was eating five guys and combined it with intermittent fasting! Cool

      Wow, I rank #1 for “five guys diet” — too funny! And yes, thanks Elaine. Not sure I’d call it “fasting,” but it’s just that the burger and fries fill me up so much that I’m not hungry again the rest of the day. 🙂
