Foreword by Dave Asprey A breakthrough program for women to revive their lost energy and vitality, developed by a leading biohacker and physician Inside of you, there is a spark—it’s what animates you, and without it, you could not live. This energy creation isn’t mystical, nor is it spiritual; it is science. We know from research that our cellular machinery transforms the food we eat and the air we breathe into the electricity that fuels us. With the right lifestyle inputs, we glow with energy; but when the demands on our bodies exceed our capacity—as is true for so many of us—we become burned out, mentally and physically.  Now, in The Spark Factor, Dr. Molly Maloof shares a program uniquely tailored to the biology of women—a plan that targets the mitochondria, the power source of the cells. As Dr. Maloof shows, the intense, all-or-nothing approaches commonly used by biohackers to optimize health—including sustained fasting, ultra-low-carb diets, and intense training—can be harmful, especially for women, because they create excessive stress in an already-stressed body, which can make us tired, weak, and prone to illness. Dr. Maloof’s innovative program—which has been used successfully by her patients—offers lifestyle changes that target the unique biology of women and provide immediate and long-term benefits. Instead of denying our bodies, we need to listen to what they are telling us. Once we become aware of our physical needs, we can give ourselves the resources to become more connected, nourished, safe, and strong—at both the micro- and the macro-level. With cutting-edge biohacking insights, strategies for personalized nutrition, hormonal health and stress management, The Spark Factor is the book women have been waiting for to help them reclaim their vitality and achieve lasting health.
