The truth is that obesity is complex and does not have a single risk factor. Lack of exercise, over-eating, depression, anxiety, gut bacteria, food chemicals (emulsifiers, asapartame etc.), refined grains and now this virus all are risk factors. They also interact with each other, making understanding complex (see http://outcomereference.com/outcomes/3 http://outcomereference.com/outcomes/3 ) I am glad though they are researching this. If a vaccine could be found, it might decrease risk for a significant portion of the population. It does not negate the fact that dish portions in North America are much larger than they should be or that there is still too much processed food in the average american diet.
