Reaching the Finish Line
Like most people, I started intermittent fasting strictly to lose weight. I had about 20 pounds to lose before my wedding, and a 16:8 schedule helped me get there smoothly. When I finally hit my goal weight, I assumed I would just go back to my old eating habits—breakfast at 7 AM, snacks throughout the day, and late dinners. I thought fasting was just a temporary tool.
The Unexpected Reality Check
Within a week of returning to my old eating habits, I realized how terrible I felt. It wasn’t just about the scale creeping back up; it was the lethargy. The sharp, laser-like focus I had enjoyed for months was replaced by afternoon slumps and a constant, low-level feeling of bloating. I missed the “fasted high”—that feeling of light, clean energy that carries you through the morning.
Fasting for Health, Not Just Weight
I quickly returned to a 14:10 and sometimes 16:8 schedule, but this time, my goal wasn’t weight loss. It was maintenance and mental clarity. Fasting gives my digestive system a much-needed break and keeps my mind incredibly sharp for morning meetings. I now view intermittent fasting not as a diet, but as an essential daily biohack for peak cognitive performance.
More Than a Diet
If you are nearing your goal weight, don’t be so quick to abandon your fasting schedule. The benefits extend far beyond the scale. From cellular repair (autophagy) to sustained energy and mental sharpness, fasting is a lifelong tool for overall wellness.
