My Daily 16/8 Intermittent Fasting Schedule
I follow a consistent 16/8 intermittent fasting window that fits real life for busy adults in their late 40s and early 50s. I eat between 11 AM and 7 PM, finishing dinner by 7 PM and fasting overnight until 11 AM the next day. This gives me a full 16-hour fast including sleep. Black coffee, water, and herbal tea are allowed during the fasting period. I avoid anything with calories that could spike insulin.
This schedule evolved from my own book methodology, which emphasizes sustainable patterns over extreme restriction. For complete beginners, I recommend starting with a 12/12 window and gradually extending the fast by 30 minutes each week until reaching 16 hours. No complicated meal plans—just focus on whole foods like lean proteins, vegetables, healthy fats, and moderate complex carbs within your eating window.
Results I'm Seeing After Six Months
Following this approach, I've lost 28 pounds steadily without the rebound effect I've experienced on every other diet. My average weekly loss is 0.8–1.2 pounds, which feels sustainable. Joint pain has decreased noticeably, making daily movement easier despite past struggles with exercise. Blood pressure readings dropped from 142/88 to 118/76, and my fasting blood glucose improved from 112 mg/dL to 92 mg/dL.
Most importantly for those managing diabetes alongside weight, my A1C fell from 6.4 to 5.7. Energy levels are stable—no more afternoon crashes that used to drive snacking. I track progress weekly rather than daily to avoid frustration from normal fluctuations caused by hormonal changes.
Impact on Metabolism and Insulin Levels
Many fear intermittent fasting slows metabolism, but research and my experience show the opposite when done correctly. My resting metabolic rate, measured via indirect calorimetry, actually increased by 6% after three months. This aligns with how intermittent fasting improves mitochondrial efficiency and reduces inflammation.
On insulin, the benefits are profound. The 16-hour fast lowers insulin levels significantly during the fasting window, improving insulin sensitivity. Continuous glucose monitoring showed my average insulin response to meals dropped by 34%. This directly combats the hormonal shifts in perimenopause and andropause that make weight loss harder after 45. Unlike calorie-restricted diets that can raise cortisol and damage metabolism long-term, this approach supports balanced hormones while targeting visceral fat.
Am I Happy With It? My Honest Take
Yes, I'm genuinely happy with intermittent fasting and its effects. It fits my middle-income lifestyle—no expensive programs or gym memberships required. The simplicity eliminates the overwhelm from conflicting nutrition advice. While the first two weeks involved some hunger and adjustment, especially with prior diet failures, those passed quickly. I feel in control rather than embarrassed about my weight journey.
For anyone with joint pain or busy schedules, this method works because it requires no elaborate prep. If you're managing blood pressure and diabetes, consult your doctor before starting, but the metabolic improvements make it worthwhile. My book outlines exact protocols for those new to fasting, including how to break a plateau if progress slows after initial success.
