Well unfortunately due to lack of government oversight, rules and regulations in the food industry, the government has allowed corporations to poison the American people with poor quality addictive food, and conveniently the poor and middle class fall victim to ultra processed easy cheap meals that reek havoc on the pituitary gland causing it to shrink, or fill with csf fluid which in return causes hormone issues stopping thyroid function....causing excessive weight gain, health problems, cancer, and diseases. My theory on the situation. And we the people allowed it. Food took a turn in the 80s everyone began really gaining weight.
