Fighterdiet is one system with different protocols and programs designed to simplify nutrition and support a healthy body composition.
Defeed 2 Refeed might begin with 28 days of Defeed followed by one Refeed day, but that is only one way to practice it. Other protocols change the intervals and ratios between Defeed and Refeed.
You do not have to follow one schedule forever. The principles provide structure while the different protocols give you options. That variation keeps the lifestyle interesting as your goals, needs and experience change.
The joy is in the eating. I always want to eat more, not less.
Love your diet or leave it.
