I have a Costco that is walking distance from my office. If I need to decompress, I walk to Costco for lunch solo, get a hot dog and a slice of pizza, sit down, and watch both the people and what's in their cart. It's so diverse and pretty fascinating.
Hot dog and a slice? That's your calorie needs for the day.
Eating a hot dog and a slice, or two slices, and I won't be hungry...for an hour or two.
...I need to get a doctor and ask about a GLP-1.
