“A select group of world’s top researchers studying obesity‌ recently gathered [at] the Royal Society…arguing about ‌‌the causes of obesity.“
They reached no consensus.
BUT:
“The 3-day meeting was infused with an implicit understanding of what obesity is not: a personal failing. No presenter argued that humans collectively lost willpower around the 1980s, when obesity rates took off, first in high-income countries‌, then in much of the rest of the world. Not a single scientist said our genes changed in that short time. Laziness, gluttony‌‌ and sloth were not referred to as obesity’s helpers. In stark contrast to a prevailing societal view of obesity, which assumes people have full control over their body size, they didn’t blame individuals for their condition, the same way we don’t blame people suffering from undernutrition challenges, like stunting and wasting.”

Opinion | Scientists Don’t Agree on What Causes Obesity, but They Know What Doesn’t

Rates of obesity won’t budge as long as society views it as a personal issue.

@MagdaSzubanski so sad… I have been weighing & measuring my delicious food for 34 years! No thing between my 3 meals but coffee, tea, or diet soda, and water of course! I commit my food written down by calling or emailing my sponsor every day! After 4 of my obese brothers & sisters died of cancer before 65 I am grateful for my 78 years. Thousands on this program known as “Greysheet.org” owe their lives & healthy diabetes free bodies to this program- like AA for alcohol this program prevents the first bite of sugar or carbohydrates (white flour products). Program around for over 50 years with multiple live & inphone meetings daily, yet doctors don’t catch on!
