EXCELLENT QUESTION. If you’re feeling great – keep going. The research is mixed in terms of the efficacy of a diet break in terms of metabolic and hormonal output. Meaning, there may or may not be valid support to show there are physiological benefits from a diet break. However, the studies do show that breaks are the #1 way to avoid mental fatigue and burnout. So do they completely help? Maybe! Do they hurt? Not at all.
If I were you – I would keep going and evaluate on a weekly basis. If you feel like you’re starting to get burnt out, or progress is stalling and you don’t want to decrease calories then implement the break strategy. Does that make sense? GOOD FOR YOU MA.
