Taubes‘ books also explained why, although I had 3 children who were offered the same food, only one of them was overweight. They explained why a child could be overweight even while eating the recommended 5 to 9 servings of vegetables and fruit a day. While not drinking soda, juice, or even milk–just water. While not eating fast food. While virtually never eating out at all. While rarely eating dessert. While being physically active.
