Enough is enough What evolution reveals about food, diet, health, and proper nutrition Daniel E. Lieberman, best-selling author and chair of the Department of Human Evolutionary Biology at Harvard University, brings a fresh, innovative, engaging, and humanistic perspective on the modern-day problem of deciding what to eat, including how to lose weight, by applying evolutionary and anthropological perspectives to basic information about nutrition, digestion, and medical science. “Fed Up” weaves together three interconnected stories. First, Lieberman recounts the interesting history of food and diets. What did we evolve to eat, and how did agriculture and industrialization change our diet? He then describes his personal experiences with major diets that reflect this history. From the raw food diet and the Paleo diet, to the Mediterranean diet and the Blue Zone diet, then trying newer weight loss diets like Weight Watchers, Atkins and Ornish. Finally, it uses an evolutionary anthropological framework to explain and evaluate the multiple scientific aspects of these diets and their effects on health. Among the many questions Lieberman addresses: What are the components of food, how does our body digest it, and what foods have we been conditioned to eat? Why do we cook? How does food affect aging and how we get diseases? Why is it easy to gain weight and difficult to lose? In addition to introducing readers to the fascinating history of food and the basics of nutrition and digestion, Fed Up debunks the conflicting and confusing nutritional prescriptions we constantly hear and read. Why are some popular diets high-fat, others low-fat, and only a few restrict calories? Why are there no diets that are highly effective in losing weight? Fed Up goes beyond simply debunking myths, providing sound scientific advice without being too dogmatic or superficial. The book summarizes what we know and what we don't know about how to lose weight and prevent weight gain, and which diets make sense in light of ancient adaptations, modern history, and the reality of food today. Lieberman also addresses the evolutionary foundations behind diets proven to help people age healthily while reducing the risk of heart disease, cancer, metabolic syndrome, dementia, and depression. Food should be enjoyed and shared, but for many, choosing food has become confusing and stressful. By telling the story of food and diets and explaining the science behind them, Fed Up engages readers with the information and understanding they need to make their own choices.
