The various studies done also show that most people regain the weight back 6 months to a year down the line. Right now the only thing we can be sure of is that weight loss only works for the minority in the long term and the only way to be slim is to always be that way. We did at least work out why processed foods appeared to be more calories, turns out we spend about 20% more energy digesting food that isn't highly processed. Which also goes to show that calories in calories out is far over simplified when people are suggesting deficits that could easily be less than 20% of daily intake. It is a chemical process and a very complex one at that and right now food science is basically garbage tier with very little in the way of good studies, most of the better end is on mice and rats.

Well, to give another point of view: I think it is pretty much understood, what is healthy and what is not and also what leads to weight loss and what doesn't. The problem is that people don't stick with it.

  People not sticking with it is really an added point to the reality that calories in/out is a very poor model for losing weight, even if it is completely correct at a physical level.

    Isn't that like saying doing exercise is a poor model for getting fit because people don't stick to it?

      It depends. Do you see losing weight as a purely physical phenomenon, or do you see it as one that's heavily influenced by psychology and other such factors? The actual physical act of losing weight i.e. reducing one's mass needs to be distinguished, in my opinion, from all the factors that actually go into that. If it turns out that in response to hunger that your brain secretes a hormone that makes you much more hungry than the average, the psychological aspect of losing weight has been compromised, even while the physical laws stay the same.

        Of course psychology comes into play. I'd know, that's what kept me from making progress with this for years. But that does not subtract from the fact that to lose weight you need to consume less calories. > If it turns out that in response to hunger that your brain secretes a hormone that makes you much more hungry than the average, the psychological aspect of losing weight has been compromised, even while the physical laws stay the same. I don't agree. You lose weight by eating less calories. If you need to manage your implementation of that technique because you have some condition that deviates from the norm, sure, that's something you have to deal with. To return to my exercise analogy, I have a medical condition that makes exercise difficult. So I have to work around my unique limitation. But I don't go around saying that doing cardio and working out is not the correct way of getting fit.

        My point isn't that 'cardio and working out' are not how one gets fit, it's that achieving 'fitness' is more than 'cardio and working out'. The words are overloaded, and I think your very last sentence illustrates that well. I also tossed up between physiological and psychological, but reasoned for my purposes they were similar enough to get the point across - i.e. that despite the physical laws being simple, the actual process is not.

        Fair enough. Guess that's why it's so hard.

Yes, keeping weight off over the long haul is extremely difficult, and only gets harder the more weight you lose. I know that for myself, beyond having to try and watch what I'm eating, I also have to stay much more active than the average person because I know that I have a slow metabolism - my body wants to hang on to every bit of energy it can. I think there is proper research going on when it comes to food science, and weight loss, but finding the good studies among the junk is difficult. We do know that there are some drugs and supplements that have moderate effects, but mostly by acting as an appetite suppressant.

  It is highly unlikely that you really have a "slow metabolism". Outside of a few rare medical conditions, metabolic rates only vary by a few percent for a given height, weight, and sex. It's more likely that you're underestimating calorie consumption. I recommend getting a resting metabolic rate test to accurately quantify your baseline. https://www.dexafit.com/services/rmr-metabolic-test https://www.dexafit.com/services/rmr-metabolic-test SGLT-2 inhibitors are effective for weight loss and don't suppress appetite. https://link.springer.com/article/10.1007/s40265-019-1057-0 https://link.springer.com/article/10.1007/s40265-019-1057-0
