In recent years, corpulence in childhood and adulthood are booming, however, there is also a situation when leaner people still exist. In fact, we are living in an environment that promotes obesity. Edward Archer, a physiologist and obesity theorist, argues that sedentary habits overtake the genes and the eating greediness as the root cause of this. He found enough evidence supporting his theory.
The first one is based on his finding that when two mice, genetically identical, ate identical food resulted in different body mass. So, food and DNA weren't the overweight factors. Then he also found that pregnant mice without wheels practice delivered the fatter descents. This is getting worse in the subsequent generations. Moreover, regarding his literature review, Edward also pointed out the metabolism differences between active pregnant mother and the inactive. The fetuses grow so fast within the inactive cases.
Second, the study of born babies by egg donation convinced that the egg donor's body mass, her own birth weight and the birth weight of her other children have no relationship with the birth weight of the baby from the donated egg.
