Yesterday I was feeling pretty proud of myself for losing a couple of pounds. Today, they’re back after rather serious birthday indulgences.

And … I don’t care. If my weight’s ever going to change, I’ve got to get over the day-to-day fretting over a pound or two and make overarching changes that just make the general trend go down. I’m not going to be able to avoid birthdays or holidays or the occasional indulgence. I just don’t have to make every day an indulgence.

There are 3,500 calories in a pound of fat. Since I’m probably 40 percent fat, that means I’ve got 432,600 calories in my body, of which 210,000 need to go away. So that’s not going to happen overnight. I’ve got to run at a calorie deficit for months.

The math isn’t in my favor. But maybe somehow I can figure this out.
