“For 60 years, doctors and researchers have known two things that could have improved, or even saved, millions of lives. The first is that diets do not work. Not just paleo or Atkins or Weight Watchers or Goop, but all diets. Since 1959, research has shown that 95 to 98 percent of attempts to lose weight fail and that two-thirds of dieters gain back more than they lost. The reasons are biological and irreversible. As early as 1969, research showed that losing just 3 percent of your body weight resulted in a 17 percent slowdown in your metabolism—a body-wide starvation response that blasts you with hunger hormones and drops your internal temperature until you rise back to your highest weight. Keeping weight off means fighting your body’s energy-regulation system and battling hunger all day, every day, for the rest of your life.”
