It's nice to see that people are developing new models and ways of thinking about weight loss but I wonder how effective this research is going to be. The conclusion of the article is the same old "eat less and eat healthier" which is fantastic advice ... and advice that a great many people don't bother to follow.
As a culture we're eating ourselves to death while worrying that low probability events like terrorist attacks are going to kill us. We're killing us and we're doing it slowly.

At least a large part of this is due to lack of education. For all the time we spend on math and science in public schools, we spend none of it on some basic principles like nutrition.
I was rather obese in high school, and the (Canadian) government foot the bill for nutrition courses and consultations with a dietitian (this is a big can 'o worms too: preventative programs like this are way easier in a single-payer system).
I now have the ability to judge what's good for me, and what isn't, as well as effective alternatives to existing choices. That knowledge has been instrumental in my weight loss.
The problem with that "fantastic advice" is that it's rarely coupled with real constructive suggestions. "Eat less and eat healthier, fatass" is unproductive when the person lacks the knowledge to make effective choices, and alternatives to break entrenched habits aren't presented. Sure, a Big Mac is universally unhealthy, but what do you replace it with? A grilled cheese sandwich isn't much better, nor are a lot of "healthier looking" alternatives (anything with mayo slathered in it is dietary suicide, regardless of how much greens you stick in it also). How do you curb hunger when in the process of downsizing your portions? Curling up in a corner isn't super effective. Blood sugar management throughout the day to get you through the rough patches? None of this is trivial knowledge.
Of course, the factor making all of this substantially worse is that the signal to noise ratio in dietary literature is horrific. For every real, researched book on effective diets, you have 3 more fad diets backed up by voodoo and pseudoscience.
Actually, I was taught a lot about basic nutrition in school. Low fat was good, complex carbohydrates were good. 4 food groups. Now apparently that is all wrong?
It's slightly more nuanced than "eat less and eat healthier," because the article is pointing the finger at some general abundance. If you like, look at this researcher's perspective directly. It's not why is this person obese but rather why is everyone getting obese? So he's not going to recommend that the problem is at an individual level, but at an institutional level.
If you wanted to translate this advice for institutions to an advice for individuals, I think it would instead be something like, "pay attention." The hardest costs to see are often the steady everyday costs -- that morning coffee, the groceries, subscriptions, and so forth. The conclusions that "abundance is the problem" and "we're throwing away too much food" seems to suggest that it has sneaked in during the moments when people aren't paying attention; people now don't pay attention to the quantity of food they buy, so more of it gets bought, more gets eaten, more gets thrown away. Look at the things that come automatic, be less worried about single failures and more worried about the general patterns.
