Regardless, he, too, falls into the same pit as so many others: the 'bandaid' approach. Putting the cart (solution) before the horse (cause). Or, putting a bandaid over the wound without addressing the causes (which are multifactorial).
Universally neglected is how to educate, encourage and motivate humans to eat less and increase activity. The solutions, such as behavior modification and choices, could solve many of the associated issues with obesity and diabetes: weight gain, dysfunction of insulin sensitivity and glucose regulation, concomitant and/or subsequent metabolic illnesses (inflammation, cardiac dysfunction, etc).
Why does the medical and scientific communities ignore the psychology of eating and sedentary lifestyles? No drugs or animal models will magically solve these dysfunctions. Let's start with healing the horse first, then we can address the cart.
