What the evidence says
Pooling 15 studies of 330 women, a 2024 meta-analysis found that energy intake in the luteal phase (after ovulation) was higher on average than in the follicular phase, though results varied a lot between studies.
Across 15 studies of 330 women, intake in the luteal phase was higher on average than in the follicular phase, with large differences between studies. The studies measured how much people ate, not how often they had cravings. These are general-population findings, and they depend on an ovulatory cycle.
What this does not show
Every figure comes from general menstrual-cycle research, not from women with the condition, and it needs ovulation. In a cycle without ovulation there is no true luteal phase, so the pattern may simply not apply. These are averages of how much people ate, not a way to explain any one eating pattern; hunger has many drivers, including sleep, medication and eating too little earlier in the day. None of this says anything about your weight, and it is never advice to eat more or less.
