It’s much more complicated than calories-in/calories-out and willpower, indicates a new study in the New England Journal of Medicine.
According to the study media release,
Professor Joseph Proietto from the University of Melbourne and Austin Health said the study revealed the important roles that hormones play in regulating body weight, making dietary and behavioral change less likely to work in the long-term.
Combining this complexity with studies that show that weight per se is not necessarily a cause of health problems, the food nannies obsession with bodyweight and diet would seem to have little scientific basis.
