Many people find it difficult to lose weight or maintain their body weight. This may not be due to a lack of discipline, but can also stem from the hormonal system. Health expert Jillian Michaels, who has personally faced this issue, spoke with numerous metabolism specialists and discovered that she had unintentionally overstimulated her endocrine system for years. After getting her own metabolism under control, she decided to share her knowledge with others. The three-phase plan in this book includes all the hormones that are important for weight loss - HFG, testosterone, DHEA, insulin, cortisol, and estrogen. Michaels demonstrates how to eliminate foods that negatively affect hormonal balance from your diet and instead incorporate foods that support fat-burning genes.
