This is such a bad study and this post is your usual garbage of the media just confusing people and making them think weight loss is impossible, all while giving them more excuses to do absolutely nothing. The idea that this "data" is in any way an accurate representation of how many calories the average person eats is just absurd. The average person cannot tell you how many calories they eat per day, they have no idea. The foods we have available today make it much more likely for a person to consume more calories than someone "thinks" they are.
You can sit around all day and blame it on leaky gut, artificial sweeteners, pesticides, gluten, carbs, fat, red meat or whatever the latest "fad villian" is, and you'll just keep failing to lose weight.
Plain and simple. Eat nutritious food that actually fills you up and satisfies you, track your calorie intake, and find a sustainable way to just eat less every day.
