I thought this was worth posting again….
Is intermittent fasting healthy for women?
It depends… I was all for it until I read Dr. Stacy Sims book ‘Roar’ and it made sense that intermittent fasting (IF) isn’t as ideal for us women compared to men.
Intermittent fasting (IF) is not the same for women as it is for men. Unfortunately, intermittent fasting was studied almost exclusively in men which showed tremendous benefit. Where the female physiology was not considered in most of the research literature.
Women are already more efficient in burning fat for fuel compared to men.
Women’s muscle mitochondria already use, and uptake free fatty acid and estrogen increases free fatty acid use which spares carbohydrates.
Women get the same great benefits of fasting from exercise.
If you want to fast, just don’t eat after dinner, and eat something (carb, protein, healthy fat) 30 minutes prior to exercise in the morning. That comes out to a 10-12 hour fast overnight.
Research found that for those that are lean or only slightly overweight and train in a fasted state had sarcopenia (breakdown of muscle mass) & an increase in cortisol which women already have higher cortisol levels compared to men. When we release more cortisol, this predisposes us to store more fat and breakdown muscle.
Fasted training puts an incredible amount of stress on the body leading to endocrine and thyroid dysfunction, inflammation, and even anemia. We women need carbohydrates for proper endocrine function. So, eat those carbs ladies!
I have struggled with adrenal dysfunction due to EBV so IF isn’t ideal for me and I have suffered the consequences of IF training. With elevated cortisol levels and further exhaustion. So now I try and eat a little something before training (healthy protein source like eggs 🍳 and fruit 🍎 and complex carbohydrates such as old fashioned oats) to keep my glycogen stores ample and my cortisol levels in check. 😊
