It may not look like it

But I have lost 5 pounds in the last week because, presumably, I have started running again (15 minutes per day) and stopped eating meat.

Hooray for short runs!

Interestingly, one of my new students, a marathon runner, when she heard I was running 15 minutes per day, said something like "all you need to do is increase that to 30 minutes per day and you'll be all good." What she didn't realize was that 15 MINUTES IS PERFECTLY FINE, ACTUALLY.

Perfectionism is the enemy of fitness. There is no minimum or maximum time to run. Run what you feel, baby. The trick is to feel what you run.
