The imbalance of hormones during your period can lower your blood sugar meaning you can crave foods with high sugar and fat content. Try and maintain a healthy balanced diet with all the food groups.
Eating low GI carbs and protein will help you feel fuller longer and curb cravings by stabilising blood sugar levels.
Avoid the quick fix of sugar as it will only make you crash and crave more sugar which will also lead to more bloating, water retention and weight gain.
