Women tend to store more fat and have a harder time converting calories than men do. In midlife, these physiological differences are amplified by hormonal fluctuation, and most women gain stubborn and harmful weight—especially around the belly—without having altered their routine at all!  A practicing OB/GYN, Dr. Mary Claire Haver found herself in this exact predicament, so she set out to develop a diet that would meet her needs. Nearly 75,000 women have now found success in Dr. Haver's unique plan for permanent weight loss and reduced menopausal symptoms by following her three interconnected strategies: • Fuel refocus: Starting in their thirties, women need a specific ratio of healthy fats, lean protein, and quality carbohydrates to efficiently burn fat. • Intermittent fasting: 16 hours of fasting with a flexible 8-hour eating window coaxes the body to draw energy from stored fat and decreases inflammation.
