Why Hormones Matter in Fasting
Hormones play a critical role in weight, mood, sleep, and energy. When fasting, your body triggers hormonal shifts that can help restore balance. Insulin levels drop, growth hormone increases, and cortisol adapts to a new rhythm. According to NIH research, intermittent fasting improves insulin sensitivity and supports fat oxidation.
Week-by-Week Breakdown
Week 1: Preparation and Light Fasting
Start with 12:12 fasting — 12 hours of fasting and 12 hours of eating. This allows your body to ease into fat burning. During this phase, consume keto-friendly snacks and hydrate well. Focus on whole foods and avoid refined carbs.
Week 2: Enter Intermittent Fasting
Shift to a 16:8 fasting window. This reduces insulin spikes and boosts metabolism. Combine it with a keto-based diet to enhance fat burning and maintain hormonal balance. Cortisol levels may adjust here, so prioritize sleep and stress management.
Week 3: Growth Hormone Optimization
Extend fasting to 18:6 or consider 24-hour fasts twice per week. This stimulates growth hormone release and cellular repair. Learn more about fasting's synergy with keto in this article.
Week 4: Autophagy and Reset
Incorporate one 36-hour fast (optional) and alternate between 16:8 and 20:4 protocols. Autophagy is enhanced during this phase, promoting hormonal reset and cell rejuvenation. For better results, avoid these common fasting mistakes.
Foods That Support Hormonal Balance
Include foods rich in omega-3s, magnesium, and B-vitamins. Eggs, salmon, leafy greens, and avocados support hormone production. To complement fasting, use this keto weight loss guide for diet alignment.
Signs Your Hormones Are Balancing
Improved sleep, stable mood, better skin, reduced belly fat, and regulated menstrual cycles (for women) are signs of success. These changes indicate improved insulin sensitivity and cortisol regulation.
Who Should Be Cautious?
People with adrenal fatigue, thyroid disorders, or women trying to conceive should consult a professional before starting. Read this article on metabolism and fasting to know what works for you. You can also check Harvard's insights on intermittent fasting here.
