How do you control your appetite before your period while on a diet?

I usually stick to a diet, but right before my period, I especially crave sweets or bread 🥹

Whenever I try to hold back, the stress actually increases, and once I start eating, I feel like I end up eating more than usual.

When my appetite changes according to my menstrual cycle, would it be better to adjust my diet a little more flexibly? I am curious how those who have had similar experiences manage their snacks or meal portions.
