According to several authors I have recently read, the trick is along the lines of Keto - Switching the body from carb burning to fat burning for energy. And as stated in comments below, the hormonal differences are also claimed to have a bigger influence than just calorie counting. How those calories are processed (glucose versus fructose versus sucrose - all with potentially different mechanisms, from what I have learned) are treated differently by my body than how saturated fats are treated. For example, there seems to be proof that saturated fat processing by the body sets the satiety signal more thoroughly than carbohydrate processing, and for longer duration. I feel less hungry, sated, so I eat less. And now when I eat, I focus more on the inclusiveness/variety of the source foods to make sure I am getting a more rounded spectrum of vitamins, minerals, and other vital components our bodies seem to require for good health. It has so far been a fun experiment, unlike other attempts I have made in the past.
