EDIT: It honestly feels like I have to add this in, even though I thought it was pretty clear from what was actually said in the article, but...
This is not an article about how CICO is irrelevant, or that calories are irrelevant, or that no one will ever lose weight following CICO methods.

This is an article about some of the inaccuracies that CICO currently has, both in measuring calories in foods, and measuring how many calories we get from them, due to all sorts of different factors. And about how sometimes, these inaccuracies can result in a lack of weight loss. It's about how CICO is one factor in weight loss, but that there are others that also impact it, to the point that if certain factors are present, it can really cause problems for some folks trying to lose weight when only using CICO.




An article, "Death of the Calorie," came out a couple days ago and discusses problems with CICO, based on the most recent research of the body . Thought it contained a lot of information that would be worth checking out.

The basic message was this: CICO, how it is used now with our tracking foods' calories alongside our calorie usage based on our activity level, is only one part of what impacts weight loss. There are a lot of other factors, and they are also important and can have a significant impact (to the point that it explains a lot about how so many people can 'follow the CICO rules' and still fail to lose weight). Also mentioned was calories measurement, and how our food labeling has a lot of inaccuracy when it comes to calories.

And all of this is contributing to people struggling to lose weight.


Some of the highlights (but definitely not all):
- There are 6 different ways manufacturers can calculate out the calorie content of their products. It is almost never regulated. But when researchers do test, about 7% of the foods are within 10 calories off. About 20% are at least 100 calories off. Information on some processed frozen foods misstates calories by as much as 70%.

- “Calorie counts are based on how much heat a foodstuff gives off when it burns in an oven. But the human body is far more complex than an oven. When food is burned in a laboratory it surrenders its calories within seconds. By contrast, the real-life journey from dinner plate to toilet bowl takes on average about a day, but can range from eight to 80 hours depending on the person [and uses more calories every hour longer it takes]. A calorie of carbohydrate and a calorie of protein both have the same amount of stored energy, so they perform identically in an oven. But put those calories into real bodies and they behave quite differently. And we are still learning new insights: American researchers discovered last year that, for more than a century, we’ve been exaggerating by about 20% the number of calories we absorb from almonds.”

- "What we do know...suggests that counting calories is very crude and often misleading. Think of a burger... Take a bite and the saliva in your mouth starts to break it down, a process that continues when you swallow, transporting the morsel towards your stomach and beyond to be churned further. The digestive process transforms the protein, carbohydrates and fat in the burger into their basic compounds so that they are tiny enough to be absorbed into the bloodstream via the small intestine to fuel and repair the trillions of cells in the body. But the basic molecules from each macronutrient play very different roles within the body."

- "All carbohydrates break down into sugars, which are the body’s main fuel source. But the speed at which your body gets its fuel from food can be as important as the amount of fuel. Simple carbohydrates are swiftly absorbed into the bloodstream, providing a fast shot of energy: the body absorbs the sugar from a can of fizzy drink at a rate of 30 calories a minute, compared with two calories a minute from complex carbohydrates such as potatoes or rice. That matters, because a sudden hit of sugar prompts the rapid release of insulin, a hormone that carries the sugar out of the bloodstream and into the body’s cells. Problems arise when there is too much sugar in the blood. The liver can store some of the excess, but any that remains is stashed as fat. So consuming large quantities of sugar is the fastest way to create body fat. And, once the insulin has done its work, blood-sugar levels slump, which tends to leave you hungry, as well as plumper.”'

- "Protein, the dominant component of meat, fish and dairy products, acts as the main building block for bone, skin, hair and other body tissues. In the absence of sufficient quantities of carbohydrates it can also serve as fuel for the body. But since it is broken down more slowly than carbohydrates, protein is less likely to be converted to body fat."

- "Fat is a different matter again. It should leave you feeling fuller for longer, because your body splits it into tiny fatty acids more slowly than it processes carbohydrates or protein. We all need fat to make hormones and to protect our nerves (a bit like plastic coating protects an electric wire). "

- “The process of storing fat—the “weight” many people seek to lose—is influenced by dozens of other factors. Apart from calories, our genes, the trillions of bacteria that live in our gut, food preparation and sleep affect how we process food. Academic discussions of food and nutrition are littered with references to huge bodies of research that still need to be conducted. “No other field of science or medicine sees such a lack of rigorous studies,” says Tim Spector, a professor of genetic epidemiology at Kings College in London. “We can create synthetic DNA and clone animals but we still know incredibly little about the stuff that keeps us alive.”

- "The amount of energy we absorb from food depends on how we prepare it. Chopping and grinding food essentially does part of the work of digestion, making more calories available to your body by ripping apart cell walls before you eat it. That effect is magnified when you add heat: cooking increases the proportion of food digested in the stomach and small intestine, from 50% to 95%. The digestible calories in beef rises by 15% on cooking, and in sweet potato some 40% (the exact change depends on whether it is boiled, roasted or microwaved)."

- "The calorie load of carbohydrate-heavy items such as rice, pasta, bread and potatoes can be slashed simply by cooking, chilling and reheating them. As starch molecules cool they form new structures that are harder to digest. You absorb fewer calories eating toast that has been left to go cold, or leftover spaghetti, than if they were freshly made. Scientists in Sri Lanka discovered in 2015 that they could more than halve the calories potentially absorbed from rice by adding coconut oil during cooking and then cooling the rice. This made the starch less digestible so the body may take on fewer calories (they have yet to test on human beings the precise effects of rice cooked in this way)."

- "Differences in gut microbiomes can alter how people process food. A study of 800 Israelis in 2015 found that the rise in their blood-sugar levels varied by a factor of four in response to identical food".

- "Some people’s intestines are 50% longer than others: those with shorter ones absorb fewer calories, which means that they excrete more of the energy in food, putting on less weight."

- "The scientific and health establishment knows that the current system is flawed. A senior adviser to the UN’s Food and Agriculture Organisation warned in 2002 that the Atwater “factors” of 4-4-9 at the heart of the calorie-counting system were “a gross oversimplification” and so inaccurate that they could mislead consumers into choosing unhealthy products because they understate the calories in some carbohydrates. The organisation said it would give “further consideration” to overhauling the system but 17 years later there is little momentum for change."

- "Officials at the WHO also acknowledge the problems of the current system, but say it is so entrenched in consumer behaviour, public policy and industry standards that it would be too expensive and disruptive to make big changes."

    I mean, the problems aren't with CICO here though, it's with poor regulation on processed food. If there wasn't labeling inaccuracies, it would absolutely work perfectly. Even so, it works well enough, as there has been a degree of success for everyone here that can stick it out.

    Even the other criticisms are most certainly outweighed by the benefits of weight loss. "Oh you won't get perfect nutrition" is not a good arguement against "if you do this well enough, you will lose weight, as it truly is the basis of every diet."

    Absolutely agree that regulations are a problem.

    The article didn't talk about nutrition, however. it has not said that we need perfect weight loss. It just talked about the fact that CICO, the way we utilize it, ignores part of how our bodies work, and also what impacts how many calories things even have, and in some cases that can be enough that it causes problems with weight loss. And that potentially paying attention to more of these other factors, while still considering CICO, would help lose weight, and in some cases, make it possible for people who aren't able to utilizing the more simplistic CICO alone.

    It's talking about problems with CICO how it's used now, not saying that calorie intake and usage don't matter.

    The average person is eating a variety of foods. The differences might become very relevant in the context of monodiets, but are they relevant in the context of the person who is eating beef, soda, broccoli, bread, yogurt, cucumbers, egg salad, apples, and almonds?

    In other words, if a person is eating a reasonable variety of foods, does it really matter if the calorie retention of average food "types" is somewhat variable? I've seen people speculating that the difference is meaningful, but never anything beyond speculation.

    I don't believe it has been studied, honestly. Most of what I've seen is anecdotal. Many times with people who switch from more carb heavy diets - not refined carbs, just carbs - to higher protein ones with similar calorie levels, and do better with weigh tloss. Or who switch to smaller meals through out the day and lose weight - similar calorie levels, according to CICO.

    That's not research, obviously, so I'll be interested to see how much of an impact it does make, years from now when hopefully we are having more studies on how these factors impact things.

    I can't tell, is the article actually about CICO or is it about calorie counting as it's often practiced? Because the CICO equation takes all of these things into account already. I don't see how anyone can say it's a problem with CICO when they actually mean calorie counting. The two are separate, but related, things and I think it would help more people if we could keep them separate instead of conflating them every single time an article about calorie counting pops up.

    Calorie counting can be imprecise and messy and takes some trial and error at times. But that does not change the calorie equation in your body. CICO has no inaccuracies. Calorie counting does. The two are not the same. And these discussions go round and round because they get all tangled up together.

    QFT!

    Again, I think that it's important to be clear about this because it helps people to understand what's going on and having more information can guide people in how to adjust their weight management plan with less struggle.

    CICO is not the same as calorie counting. And conflating the two, as has happened several times in this thread, is why these posts go round in circles.

    CICO is science. It's a description of what's happening in your body.
    Calorie counting is a method of observing and affecting CICO in order to get a desired outcome.

    Calorie counting is a verb. It's a thing you can do or use. CICO is a noun. It's a thing that's happening.

    So, let's get an analogy going. If I came into this thread and said that gravity doesn't work the same for everyone I suspect that I would get a whole bunch of woos and a whole bunch of posts trying to explain why I'm wrong. But aha! Some people fall faster than others. Some are more likely to trip. Cats always land on their feet! People use different types of gravimeters and some of them don't work as well as others. Some people have faulty gravimeters or no gravimeter at all. They don't experience gravity the same way that others do so gravity is not the same for everyone.

    That's preposterous, of course. Gravity on earth exerts the same force on everyone, whether they can measure it properly or not. Likewise, the CICO equation works the same way in everyone. There are many variables in that equation that make people different, but the long, drawn out, complicated equation works the same for everyone.

    The problem is not that CICO is faulty but that calorie counting can be faulty. CICO is what it is. CICO does what it does. And understanding the difference between CICO and calorie counting can help people to understand where to turn their attention and energy when their plan isn't working. You can change your calorie counting methodology. You cannot change how CICO works.



    I understand the distinction, but I think this article is taking on both to a certain extent. It is saying not only that calorie counting is flawed, but that the idea of the calorie is flawed. It is saying that there is no such thing really as a calorie, that the 4-4-9 breakdown we use isn't accurate. That different carbs, protein, etc all have different energy levels associated with them and shouldn't be treated the same. That different bodies process energy differently so a calorie for one may not be the same as a calorie for another.

    To me that goes beyond just questioning whether calorie counting can be accurate. It seems like it is taking to task using calorie as a unit of measurement at all.
