'Protein hunger' drives overeating, large-scale population study shows:

A year-long study of the dietary habits of 9,341 Australians has backed growing evidence that highly processed and refined foods are the leading contributor of rising obesity rates in the Western world.

The new study, in the latest issue of the journal Obesity conducted by the University of Sydney's Charles Perkins Centre (CPC), was based on a national nutrition and physical activity survey undertaken by the Australian Bureau of Statistics (ABS), and further backs the 'Protein Leverage Hypothesis'.

First put forward in 2005 by professors Raubenheimer and Stephen Simpson, the Protein Leverage Hypothesis argues that people overeat fats and carbohydrates because of the body's strong appetite for protein, which the body actively favours over everything else. Because so much of modern diets consist of highly processed and refined foods – which are low in protein – people are driven to consume more energy-dense foods until they satisfy their protein demand.

[...] "It's increasingly clear that our bodies eat to satisfy a protein target," added Professor David Raubenheimer, the Leonard Ullmann Chair in Nutritional Ecology at the School of Life and Environmental Sciences.

"But the problem is that the food in Western diets contains increasingly less protein. So, you have to consume more of it to reach your protein target, which effectively elevates your daily energy intake.

[...] Participants with a lower proportion of protein than recommended at the first meal consumed more discretionary foods – energy-dense foods high in saturated fats, sugars, salt, or alcohol – throughout the day, and less of the recommended five food groups (grains; vegetables/legumes; fruit; dairy and meats). Consequently, they had an overall poorer diet at each mealtime, with their percentage of protein energy decreasing even as their discretionary food intake rose – an effect the scientists call 'protein dilution'.

    But - - - what happens when you add all that protein to an environment of preservatives, additives, food colorings, flavorings (artificial and natural) and it all reaches it's expiration date?

    Sounds like a potential Frankenstein's monster!

    Same as mixing vinegar and baking soda.

    Actually you sorta stumbled on one of the issues:

    A particularly insidious proposed mechanism is the “protein decoy effect,” in which homeostatic protein seeking responses are diverted by cheap, abundant, fat- and carbohydrate-rich, umami-flavored, savory snack foods, which exacerbate rather than ameliorate the protein deficiency they are selected to redress [(28)].

    ( https://onlinelibrary.wiley.com/doi/10.1002/oby.23578 [wiley.com] )

    Still, fundamentally, the core problem is the (lack of) protein content: Force the industry to meet a minimal macronutrients targets and the additives will no longer be required so they'll be removed.

    But yeah, the problems isn't processed food but certain practices in the food industry and they can all be resolved by simply reverting the recipes to using protein powder instead of pectin(=starch=carbs) and MSG(=sodium+carbs).

    If the field wants to stop being treated like a pseudoscience, it should focus on the actual problems at hand.

      Typo correction: Glutamate is a non-essential amino acid, not a carbohydrate... Proofing is hard.

      Meanwhile, TPTB tell us we need to reduce our meat intake.

        Which powers-at-be? The USDA places meat in their "food pyramid" at excessive levels due to pressures from the beef industry: https://en.wikipedia.org/wiki/Food_pyramid_(nutrition)#Controversy [wikipedia.org]

        The people telling you to eat less meat are some environmental and animal rights groups who oppose poultry and even fish on various grounds, some being more legitimate than others, and the American Heart Association that focuses on red meat and is telling you to get your proteins from plants, fish, poultry and dairy instead: https://pharm.org/red-meat/american-heart-association-study-cut-out-red-meat/ [pharm.org]

        Regardless, the people in power are definitely not telling you eat less meat.

          Bb,but I saw an advert on TV telling me the looney libtards want to make hamburgers illegal that's why I voted for a sensible moderate who loves Freedom.

            Actually, the consumer advocacy concerns regarding pink slime [wikipedia.org] and plumping [wikipedia.org] can be alleviated by requiring manufacturers to meat protein content standards so no matter how much fat and water they inject poultry, ham and beef, it will still not cause the protein dilution affects on appetite as dissuaded in the article.

            In fact, I've seen a paper examining adding pea protein powder to hamburgers as filler and the results are pretty good: https://www.sciencedirect.com/science/article/pii/S0023643821019277 [sciencedirect.com]

            So, profit?
