Six weeks ago, I started an intermittent fasting eating schedule. I wanted to lose some belly fat. From what I gleaned on the internet about intermittent fasting, when we go longer than usual without eating, our bodies burn fat for energy instead of the customary fuel source, glucose.
Feeling some hunger is also in line with the experience of most humans throughout history. They put on fat from feasting, and when food was scarce, they felt hungry and burned fat. Hunger was part of their lives, and the human body is designed for occasional fasting.
After reading about various configurations of going without food (some fast 1-2 days a week, some do 12-hour daily fasts, etc.), I decided to go with a 16-hour daily fast, 7 days a week. Breakfast is the easiest meal for me to skip. I do more physical work in the afternoons and need energy for that, and I enjoy unwinding with dinner. So from 8 pm until noon I would fast. A good chunk of that time, I would be asleep — a natural 8 hour fast. So really, I only had to abstain from eating the first few hours of each day.
