Lucan and DiNicolantonio explain why an approach that advocates
eating fewer calories is inadequate and simplistic,“By this thinking, a calorie's worth of salmon, olive oil, white rice or vodka would each be equivalent and each expected to have the same implications for body weight and body fatness.”.
While its practical definition, Lucan writes that'a mentally healthy person is one
who is happy himself, lives peacefully wif his neighbors, makes his children a healthy citizen and even after performing these basic duties in which so much power is left in society to do something in the interest of people.
