Here are graphs of my calories consumed every day and my weight (a 3-day average).

Also attached is a spreadsheet of the nutrition information of everything I ate that month.

Though my posts became infrequent, I did succeed in eating nothing but McDonald’s for 30 days, and lived.

My weight did not change significantly overall, though it did rise in the first week, and drop back to normal near the end.

I ate 75 double cheeseburgers (one dollar each), 12 McChicken sandwiches (though it felt like more), 13 large fries, 13 hot fudge sundaes, 11 large milkshakes, and a couple dozen sodapops, and a bunch of other stuff. It was tiresome, but I never felt malnourished.

My fitness seemed fine. No depression, except sometimes when the family was eating something delicious and I had to have another darned cheeseburger. My VO2 Max, as measured by the stairmaster at the gym, went from 39.2 to 45.7 — pretty good progress for a month of working out.

I ate at a different McDonald’s yesterday, and now that I look at the receipt, I’m surprised to find that it was more expensive than my local McDonald’s.

The 10 piece McNugget was $3.99, instead of the already-outrageous $3.39, and the large french fry was $1.99 instead of $1.69.

That’s a 15 percent increase in the distance of four blocks. I’d expect to pay a premium in Alaska, or an airport, but I’m surprised there’s that much variation within the same neighborhood.

I haven’t been keeping up the daily blog, but I have continued eating nothing but McDonald’s. It’s so boring eating the same food every day that I can’t bear writing about it, too, I guess.

I did make a meaningful change to my diet on day 12: I cut out the sodapop. Still plenty of cheeseburgers and ice cream and fries, but no more Mr. Pibb.

Why? I’m willing to concede that eating 4000+ calories per day will cause one to gain weight, even if one exercises. (Shock!) If you look at the weight graph, you’ll see I put on about 6 pounds in the first 10 days, and I’m afraid for my health if I put on 18 in a month — Mary would kill me. So no soda. Otherwise, pretty much the same.

I’ll post the full data of everything I ate and all my workouts from time to time, but not three times a day.

I also added some weightlifting to my hour of treadmill stuff. It turns out that when I lift weights, I get really sore, and have mostly been skipping my next-day workout.

Weight before workout: 182.5. Ooh, boy, another batch of pounds. Was it skipping yesterday’s workout that caused the increase, or was life just catching up?

I did 65 minutes of cardio (977 calories total), and weighed 180.5 afterward. I also did a few minutes of random weightlifting.
