Number 23 of 30 scientifically verified ways to optimize energy metabolism: the intermittent fast. You’re not changing what you eat; just when you eat it. The science shows that giving your body a break from eating fends off diabetes and brain damage – if you’re a mouse or fruit fly, at least. There are different fasting methods, and we’re going to pick the simplest. Combined with number 24 (coming up tomorrow: eat breakfast), this puts dinner around 4:00. Oof. Proponents of intermittent fasting insist it’s a full out lifestyle change, but for this challenge, let’s just try it for a day or two and report back on how it goes.Eat dinner at 4:00, then put your fork away for the night.

Also, a heads up about number 25 of our energy boosts – on Thursday, your boost is to go find a pool and go lounge. Plan ahead. If you’re in Atlanta, we’ll be at the Grant Park pool at 6:15.
