Fasting by eating just one or two meals each day may seem to some as an excessive and unduly restrictive dieting strategy. However, our daily eating schedule-three meals plus snacks-doesn't always correspond to our bodies' natural cycles. In fact, eating three meals a day may contribute to metabolic inflexibility, which can result in inflammation, tiredness, and other chronic health issues. For millions of years, our bodies have worked best when we fasted on a regular basis.
