I am willing to give this diet a shot. Thanks for the advice!

However, I have tried the keto diet and also cutting out carbs before, but there was no difference. Cutting out dairy also made no difference.

My energy crashes the least when I eat candy . I have no symptom of diabetes, but I need to eat hard candy in the morning to reduce dizziness. My energy crashes more when I eat fruits/vegetables in the morning. My energy crashes the most when I eat heavier protein.

Exercise can trigger the heart palpitations as well. Sometimes I have a thumping headache near my temples, before my heartbeat increases and I fall asleep
