Would you lose more weight drinking two liters of coca-cola a day or eating the equivalent total calories in a high-fat protein rich food?
I would think your body would burn through the straight sugar calories much faster than the protein. But consuming all the sodium in the coca cola product might cause water retention.
Toss up. But most if not everyone's diet will never be that one-dimensional.
You completed omitted any impact that hormones will have on this equation.
The sugar you eat in Coke is going to send your blood sugar / insulin levels to sky rocket. High insulin levels cause fat storage. You could "lose" weight, but your body composition (or body fat percentage) certainly won't improve.
Insulin levels cause fat storage in order to lower blood sugar levels. If all you did was chug two 2-liter bottles of Coke, you'd temporarily go through lipogenesis, then go back through lipolysis to pull the stored calories back out for use later in the day.
Insulin doesn't magically make you fatter if you're consuming the same number of calories. A high protein/fat diet is more satiating and you consume less calories, but insulin is not evil.
Most people when they say they want to lose "weight" meant they want to lose "fat" and improve body composition.
Focusing solely on calories in / calories out omits any effects hormones have on fat burning / storage.
In your scenario - yes - if someone drank 2000 calories of coke and that's it, they might not get "fatter", but that's not how real life works.
99/100 times, that person who drank 2000 calories of coke is going to be starving shortly afterwards and isn't going to simply "fast" and let lipolysis take place. Instead, because sugar causes ridiculous cravings - they're probably going to crack and down another 1,000 calories of another carb intensive, sugary food ('cause cravings) until their calorie intake exceeds their calories used and their hormone levels are thoroughly trashed.
I like hypothetical scenarios as much as the next guy, but focusing strictly on calories in / calories out and ignoring hormone imbalances, cravings and other real-life factors are typically symptoms of someone who reads lots of books, but hasn't has too many real life case studies to work with.
No, we aren't arguing semantics. You're arguing semantics now that you have a lot of qualifiers on the statement you made earlier.
Your initial assertion was that high insulin levels cause fat storage (really, insulin causes blood glucose to drop, either through glycogen uptake in muscle tissue or lipogenesis and glucagon causes it to rise via the opposite mechanisms) in response to the prompt:
> Would you lose more weight drinking two liters of coca-cola a day or eating the equivalent total calories in a high-fat protein rich food?
I'm sorry that my made-up scenario isn't the same as your made-up scenario, which now has a ton of conditions and it suddenly "real life".
Yes, in real life, someone who consumes 2000 liquid calories is going to be hungry. As is someone who consumes 2000 calories of bread. Or donuts. Or anything else which is digested rapidly (and this is exactly why I brought up satiation).
But this isn't a "hormone imbalance." This is, in fact, absolutely typical and ideal action from hormones doing their job, unless your made-up-real-world scenario now also involves people with insulin resistance. Because 2000 calories is 2000 calories, and while studies show that the normal metabolic range is +/- 200kcal from calculated bmr, "hormones" are not some wild card. Men eat more (higher bmr, testosterone promotes liposysis and better nutrient partitioning), but a man or a woman doesn't go through massive hormonal changes on a regular basis, and consumption of an equivalent number of calories from different macronutrient groups can be expected to have about the same effects on composition (unless it's all protein, in which case you get to worry about dying).
If you want to discuss hypothetical scenarios (2000 calories of sugar vs equivalent total calories in a high-fat protein rich food), discuss them. But don't change your stance when someone questions you.
The problem with people who do things like drink 2 litres of coke, is that they become insulin resistant. Meaning they produce a lot more insulin than required, as thier bodies ability to gauge how much insulin is thrown out of wack (by the spikes in sugar).
Now when you have something that only requires 2units of insulin, your body outputs 4 (because of insulin resistance) and now fat cells are being created when they shouldn't be. (Because insulin is what regulates fat storage, i.e insulin takes the sugar out of your blood by shoving it in a fat cell).
Keep this up, and you eventually end up diabetic.
You are both saying the two different sides to the same coin.
EDIT:
To be clear - If you have regulated insulin (by controlling carbs and suger) you will gain less fat (but lose it normally). If you starve your body of those sugars in the first place you will lose more than you gain (regardless of insulin). This is why WeightWatchers works, and why Excercising your arse off works, and also why Paleo/Atkins/Low-carb works.
I can't reply to your comment & don't want this to turn into a flamewar, but we're essentially saying the same thing.
Calories in > calories out can "work", but it's not an efficient way to address body composition - especially with people new to nutrition because of the hunger / craving factor that invariably comes up.
Also - continually drinking 2000 calories of coke is going to lead to chronically high blood sugar / insulin levels and will degrade their insulin sensitivity over time.
You have to eat zero fat on a sustained basis and absolutely gorge on sugar to make lipogenesis happen at all. The body can store pounds of sugar as glycogen. In humans lipogenesis is an extremely inefficient process that burns up nearly 30% of the calories in conversion.
Zero fat, high sugar diets have been a proven way to get lean for decades. If you put people on a very low fat diet with a good amount of protein (say 90 grams), you can allow them to eat sugar and starch ad libitum and they will get lean. No need to count calories.
Humans are very inefficient at converting carbohydrate to fat; we don’t do it under normal conditions. (The cost for this conversion is 30 percent of the calories consumed.) Subjects overfed large amounts of simple sugars under experimental laboratory conditions, however, will convert a small amount of carbohydrate to fat. For example, both trim and obese women fed 50 percent more calories than they usually ate in a day, along with an extra 3 ½ ounces (135 grams) of refined sugar, produced less than 4 grams of fat daily (less than 1/8 ounce). That’s just 36 extra calories stored as fat per day. You’d have to overeat all of those extra calories and table sugar every day for nearly 4 months just to gain 1 pound of extra body fat.

"Eucaloric replacement of dietary fat by CHO does not induce hepatic DNL to any substantial degree. Similarly, addition of CHO to a mixed diet does not increase hepatic DNL to quantitatively important levels, as long as CHO energy intake remains less than total energy expenditure (TEE)."
You need to read more than your confirmation bias-laden sources if you believe these things. Stop reading Taubes and pick up Aragon and McDonald. The best way to actually learn the truth is to read something that runs counter to your viewpoint and analyze it.
> The best way to actually learn the truth is to read something that runs counter to your viewpoint and analyze it.
The best way to learn the truth is to experiment for yourself and see what actually happens.
I'm always willing to read counterpoints - but I've yet to see anything that counteracts the fact that high insulin levels prevent the fat burning process from taking place. Insulin isn't evil and if you time it right - it can actually be quite beneficial, but chronically elevated insulin levels are a problem for people trying to burn fat.
I'm happy to read any links you want to send my way. In the meantime, I suggest you take a look at John Kiefer's work at http://body.io to see how your hormone levels can have a bigger effect on your overall body composition than straight calories.
>body composition (or body fat percentage) certainly won't improve.
It most certainly would improve. He might have a better result with a more reasonable diet, but he would still see a significant reduction in his body fat percentage if he stayed on the diet long enough.
> I would think your body would burn through the straight sugar calories much faster than the protein. But consuming all the sodium in the coca cola product might cause water retention.
It is more complex then the situation you presented.
Sugar is literally a poison, it's the reason why unchecked type 1 diabetes leads to deterioration of various organs. The body knows this but also runs on the stuff, so it tries to keep it at a sane level that does the least amount of damage to the body while still providing enough energy to run.
When blood sugar spikes, the body starts storing in the liver, when that storage is used up, it starts converting the sugar into cholesterol(and fat). Insulin is the primary hormone involved in this mechanism. So the body starts storing the energy in alternative non-immediately usable forms not because it runs out of storage and an excess of sugar in the blood is extremely harmful.
Protein based or complex carbs which convert to sugar interaction with this bodily hysteresis differently. It does not cause the blood sugar spike and the associated insulin surge.
Using a completely different line of logic, it's trivial to say that energy in / energy used is the dominating factor in weight gain or loss, when you examine people that eat a lot and don't gain weight regardless of exercise/fitness related factors, vs those that eat moderate portions with moderate exercise but nevertheless do not lose weight.
In short, there are a lot of factors involved here.
"a substance that is capable of causing the illness or death of a living organism when introduced or absorbed."
Water can be a poison if it wants to be too, however, sugar is orders of magnitude more poisonous than water.
Sugar is not a substance like water in which "hey if you drink enough water, more than most people can even if they were trying to, you can die." It's more like, the body is constantly struggling to keep blood sugar levels at a level that won't kill it, and there are great many metabolic disorders in which it fails to do this, and dies.
Also, there are diets which can simply overwhelm the body's ability to regulate blood sugar levels, some which lead to the body dying, see: type 2 diabetes.
If you count up the premature deaths(looking at human-life-years lost is probably most informative) associated with type 2 diabetes and heart disease related to sugar-induced metabolic disorders, one might be surprised that the poison we call sugar may have one of the highest kill counts of all known poisons. And to top it off, it happens to be a poison that we are, by an unfortunate evolutionary happenstance, generally addicted to. Oh yeah, it's also supported and pushed by multiple billion dollar industries with significant lobbying power.
If I drink a litre of water in one sitting, I feel queasy and unwell. This is "the illness of a living organism". I've done it before on hot days - it's not like it's hard to drink a litre, most people can do it easily. I have been poisoned by water, using that definition, but most would say that using the term that way is needlessly pedantic.
Are you aware that just like the body regulates sugar, it also regulates water? The body tries to maintain the right level of water, and it's easy to show: drink a lot. In short order, you'll be pissing a lot, to get rid of the excess water. People that have their ability to regulate water inhibited also show a lot of illnesses as a result - in terms of demographics, this can be seen in cultures where women aren't allowed to go to the toilet during the day. Sugar doesn't get magical, unique treatment in biology - water even has its own organ system that is primarily devoted to managing water content. And if you want to get socio-political about it (unsure why this means it's a poison...), we're also addicted to water and nations go to war over fresh water supplies... something that is pretty rare for corn or cane fields.
The point is that labeling sugar as a poison is being simplistic, and the picture is far more complex than that when discussing diet.
>I've never seen sugar implicated as a cause of type II diabetes.
Sugar has been implicated as a cause of type II diabetes by many people [1]. Whether they are right or not is up for debate.
Even my great grandmother, born in 1915, used to warn that too much sugar would cause diabetes. According to her this was conventional wisdom when she was young.
And my grandmother said dietary oil causes acne. Conventional wisdom isn't science. If it were, all science would ever do is confirm conventional wisdom.
I'm not arguing conventional wisdom is evidence that sugar causes diabetes.
The GP said he or she had never seen sugar implicated as a cause, like that was something he'd never heard of--when in fact it was and is a common belief. Whether that belief is true isn't something I'm arguing.
There is a new documentary called Fed Up, produced by Katie Couric, that I'm pretty sure will say that sugar is the most likely cause of the diabetes epidemic. I have it on preorder.... out Sept 9th.
No, it really isn't. "Sugar" is not a poison. "A very large dose of sugar" is a poison. It's a very important distinction. Small or moderate amounts of sugar do not cause problems, and in fact give the organism more energy to work with. If you take the position that the substance is a poison simply because it's possible to hurt yourself if you take ridiculous amounts of it, then the term 'poison' becomes meaningless. Everything then becomes a poison, and it's then completely redundant to label something a poison.
Besides, sugar is the primary fuel for your brain; without sugar, we don't exist. It's a funny sort of poison that is necessary for our existence.
I'm not saying it's useful to call sugar a poison, and I don't generally refer to it as one. I'm saying it fits the definitions I've seen of poison, and that makes it literally a poison.
> Besides, sugar is the primary fuel for your brain; without sugar, we don't exist. It's a funny sort of poison that is necessary for our existence.
Arsenic, along with several other low-dose poisons, is also necessary for our existence[0]. Do you disagree it's a poison?
Let's stop being silly. No substance is or is not a poison. You have to talk about concentration and mass relative to everyday exposure when you claim something is poison.
Would you lose more weight drinking two liters of coca-cola a day or eating the equivalent total calories in a high-fat protein rich food?
I would think your body would burn through the straight sugar calories much faster than the protein. But consuming all the sodium in the coca cola product might cause water retention.
