Pent-up frustration.
You might feel this when you are eating well, and are tempted to go on a eating binge. "I've been so good for a long time. C'mon. Let's let loose."
Letting loose occasionally can have its rewards, provided you can be disciplined on both ends of the run, and you make smart decisions even within the binge.
Just because you are letting loose doesn't mean you turn off your brain.
As an example, I offer up my 41 hours in Minneapolis. I took the opportunity to go on a mini-binge, being good before I went, and feeling the need to be good after I came back.
Being good was almost too easy before, knowing that I would get a reward soon helped me be better. That and the stress of getting ready for a vacation. I also knew that I would have a limited time, so I couldn't suffer too much damage.
Not that I didn't give it my best; I did rather well.
We landed 30 minutes early in downtown Minneapolis: 5:30 am. I was hungry but I had to walk, in the dark in a brand new city, before I would find food. Breakfast is really important for me to get the sooner, the better. But this morning would have some misadventures; Breakfast came about 3 hours after my arrival — in St. Paul.
My first choice was Hell's Kitchen, but my info was off, and the empty storefront made me sad. I then walked to the Minneapolis Farmers Market in the early morning; the market is off the beaten path on foot. You can tell this as you pass the Greyhound station and the Salvation Army outlet. While food was all around, no suitable breakfast came forward. I did buy some tomatoes to snack on for later.
Walking back, I tried to figure out what my next step would be, and where I would find breakfast. I took the bus to St. Paul, hoping that might be a better option for breakfast. In downtown St. Paul, I found Mickey's, a legendary dining car type diner. I loaded up on the breakfast special: two sunny side up eggs, two sausage patties, toast, and homemade hash browns. Later than I wanted, and more than I would normally eat. But the 3-hour period was longer than I usually wait for my petit dejeuner. Then again, the excitement about being in a new city and a lot of walking allowed for some level of grace.
I inadvertently did something that helped: I ate in the middle of the night. The bus made a driver's stop and I grabbed a fast food hamburger. Can't remember the last meal I had in the middle of the night. Traveling does some atypical things to your system.
Lunch was stop #1 on the food truck express. I couldn't handle much at dinner: a small tray of nachos and cheese at Target Field. And other than snacking on the little tomatoes, I had no other food before dawn.

Breakfast was stop #2 on the food truck express, making up for lost stomach time. I finished off the small tomatoes at breakfast.
Lunch came late, about 2:30 pm, and I was barely hungry. I discovered (through help) the new location for Hell's Kitchen. These things will happen when traveling in a new city.
I ended up eating two meals at Hell's Kitchen. The first was a walleye (local staple) BLT on sourdough with lemon scallion tartar sauce with sweet potato fries and homemade ketchup. The second was a bowl of wild rice (local staple) porridge with maple bison sausage. And that satisfied me until 8 am the next morning. No late night snacks for me on the way back.
