Their research finds processed meals and quickly digestible carbohydrates could also be what’s actually behind society’s rising waistline.
According to the Centers for Disease Control and Prevention (CDC), over 40 % of American adults classify as overweight.

It’s a vicious cycle that leaves folks pondering they’re nonetheless hungry and persevering with to pile on extra non-filling meals.
“Reducing consumption of the quickly digestible carbohydrates that flooded the meals provide through the low-fat weight loss plan period lessens the underlying drive to retailer physique fats. As a end result, folks could shed pounds with much less starvation and wrestle,” Dr. Ludwig says.
