Kiefer: You definitely can, because I’ve done it before. But it’s kind of a mixed bag. No matter how many carbohydrates you squeeze in during that two-hour period, the likelihood of them getting stored as fat is almost zero. The problem is if you eat a ton of fat right then. I didn’t get into this in the book because it taps into another research vein. But in that window after you train at night, it’s hard to get fat into fat cells for storage. Your muscles, on the other hand, are primed to store triglycerides. [Bodybuilders take advantage of this before a contest. They fill their muscles with fat rather than carbs so they can hold a dry look on stage.]
