Many of my patients also do quite well when they increase their carb intake around their periods and ovulation—once or twice a month—as opposed to cycling in added carbs every week. Here’s what to do: On days 1 and 2 of your menstrual cycle, increase your carbs. You can also try increasing your carb intake after ovulation, around days 19 and 20 of your menstrual cycle, which is about 5 days after ovulation. You can experiment with this and see how you feel.
