Kris's practical takeaway

Here's what to do with it.

Meal timing can be tested as a practical preference, but the schedule still needs to fit work, training, hunger, protein, and social life.

Ways to use it

Safe ways to apply it.

Earlier is an option to test, not a rule to obey

The schedule has to fit the person and the training
