The female body has various stages (5 to be exact) that influence metabolism as we flow through the menstrual cycle. Eating right during these phases helps women gain less fat, reduce night binging, and avoid drops in energy as they go through this monthly journey. There are two main hormones' at work: progesterone and estrogen and both have huge effects on the metabolic fuel sources the body prefers.
The thyroid gland secretes horomones that control how quickly the body burns calories and uses energy. When the thyroid is underactive, it doesn't make enough hormones and common symptoms are fatigue, intolerance to cold, slowed heart rate, weight gain, muscle weakness, hair loss, dry skin, cold hands and feet, decreased sexual interest, insomnia, infertility, puffy face, slow speech, tinnitus (ringing in the ears), and heavy menstrual periods.
