In part 2, I describe how glucose spikes affect us in the short term—hunger, cravings, fatigue, worse menopause symptoms, migraine, poor sleep, difficulty managing type 1 diabetes and gestational diabetes, weakened immune system, worsened cognitive function—and in the long term. Dysregulated glucose levels contribute to aging and to the development of chronic diseases such as acne, eczema, psoriasis, arthritis, cataracts, Alzheimer’s disease, cancer, depression, gut problems, heart disease, infertility, PCOS, insulin resistance, type 2 diabetes, and fatty liver disease.
