Decision Fatigue

## Decision Fatigue

Decision fatigue describes the well-documented decline in decision quality that occurs after a person has made many choices. In the context of eating and weight management, this is particularly relevant because food decisions happen constantly — often 200+ per day according to research.

Each decision costs a small amount of mental energy: Should I eat now? What should I eat? Is this enough? Should I have seconds? Should I log that snack? By evening, the capacity for deliberate choice is reduced, which is why many people report losing control at night even after a perfectly structured day.

The practical solution is not more willpower — it is fewer decisions. A fixed eating window (intermittent fasting) eliminates hours of food decisions. A pre-set calorie target and planned meals reduce choices to execution. Simple, repeatable foods mean less deliberation at each meal. The structure does the deciding so you do not have to.
