Premenopause usually begins in your 40s. Premenopause is when the hormones in a woman's body begin to decrease. Some common symptoms you may notice in your 40s include mood swings, difficulty concentrating, frequent headaches, hot flashes, etc.
Not eating enough protein
After premenopause, women will lose about 10% of their muscle every ten years. Hormonal changes reduce insulin sensitivity. Without enough protein, maintaining muscle mass becomes more difficult and cells in the body have difficulty processing insulin effectively.
Excessive cardio
Exercising too much cardio can reduce progesterone levels - an essential hormone that affects the menstrual cycle, mood and sleep. This can make you feel exhausted or lose your hormonal balance.
Drinking too much alcohol
Drinking alcohol releases histamine. As estrogen levels decrease with age, your body has a harder time processing histamine. This can lead to disrupted sleep, making you feel exhausted all day.
