Sure, I’ll be the first to tell you that consistency is essential to achieving change in your body. For as long as I can remember I’ve preached the importance of staying focused, with your eye on the prize, and making sure to stick to both your diet and workout plan if you want to see progress beyond that of the tens of thousands who aren’t so diligent as you.
Of course rules were meant to be broken, and this one is no exception. In fact, I would actually encourage you to take some time off from your diet and training periodically. Yes, you read that right. Take time off. Getting away from the gym and off your diet for a short spell could do you a world of good by taking the edge off and letting your body recover from the consistent workload you put on it.
Of course I’m not recommending that you become lethargic and eat junk food for a month or two. However, a couple of days a month in which you don’t think about sets and reps or count calories can be incredibly invigorating, giving you the motivation to approach your regimen with newfound enthusiasm when you do come back to it.
