A Question About Sugar
Replies
-
From a nutrition aspect, I try to limit my intake of added sugars from processed foods and such. I don't count sugars from fruits and other natural sources. I watched a really interesting documentary yeaterday though called Fed Up. According to that, sugar calories (all sugars, natural or processed) aren't treated by your body the same way and are more readily stored as fat instead of used as energy. It is worth watching if you would like to learn more about sugar in your diet.
That's vague.

GI is pretty much bunk for non-diabetics

"The unexpected findings of the study by Sacks et al suggest that the concept of glycemic index is less important than previously thought, especially in the context of an overall healthy diet, as tested in this study"

Dubble, please take information from documentaries very lightly, especially fed up. It was produced by a journalist and it cherry picked science to sell a point

i gather, the general consensus is that you should not worry about sugar unless (or until) you have a medical condition.
i am assuming that "medical condition" is Type 2 Diabetes.
just be wary that diabetes does not simply materialise overnight. it takes years before its symptoms manifest (and once they do, there is no going back) and by then in all likelihood, some damage to your body would have occurred.
not trying to scare you. but, imho, it is good to cut back on sugar and refined carbohydrates and to keep an occasional eye on your blood sugar levels. take it from someone who has lived with this debilitating disease for 15 years.
True. However, according to the National Institute of Diabetes and Digestive and Kidney Diseases, physical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.

So watching your weight (a function of calories in/calories out) and getting physical activity are much more effective in preventing/managing diabetes than counting grams of sugar IMHO0 -

I am not sure if sugar is clinically or chemically addicting, but I do know that once I stopped eating simple carbs (and therefore sugar) for a few weeks, my cravings for and evening binge-like behavior on carby snacks (crackers, tortilla chips, Goldfish crackers) completed disappeared. I feel more even-keeled during the day and am not always thinking about my next meal.
It has changed my behavior in a major way. And I've lost 20# because I feel more satiated on protein and fats, so it's easier to sustain a caloric deficit.
Just my personal experience. YMMV.
Hate to be the bearer of bad news, but crackers, tortilla chips, and goldfish are complex carbs. Simple carbs would be fruit.0 -

No. The sugars are treated exactly the same way, as they are the exact same molecules. The human digestive system doesn't recognize "Apple" or "Twinkie." It recognizes glucose and fructose and digests them accordingly.
Also, unless you're eating kilograms of sugar, it won't be stored as fat. Sugar is almost never stored as fat, as the body readily uses it as its main energy source. It won't remain in the body long enough to be converted to fat, unless, like I said, you're eating about a 1000 grams in a sitting. That would be the equivalent of 25 cans of Coke in one sitting, for perspective.0 -
There isn't a twinkie molecule?
Where is your backup for this?0 -
I try to stick to 25g or less of processed sugar a day plus any fruit i might eat, usually one piece, but i have never craved sugar. Many days I am well under that.0

Aside: I was once traveling in a third world country and drank gasoline by accident because it was stored in a water bottle. Not having the same medical opportunities as they do here in the states, the doctor's response was to have me eat straight sugar and drink milk for the next 24 hours. And what a glorious 24 hours it was.0 -
drank gasoline. Before, or after you were rip blazin' drunk? lol.0

Thanks for the link and did watch Fed Up.
Fed Up is a well done piece created over like three years. Not all here are in agreement but from the science/medical aspect I found it to be helpful in getting out the word that those who make money selling us food can go heavy on the sugar to make it taste better.

From what I learned last night on another thread I do not think sugar is addictive in a real sense but for some reason I craved it really bad until I told myself it was poison.
Glad you did not develop the craving. Getting off of sugar helped with weight loss because without it the drive to over eat faded.

There's less sugar in food now then there was 10 years ago. The reason people disagree with Fed Up is because it should be called Made Up, because every part of the science/medical aspect that you found helpful was completely fabricated.0 -

So you crave straight sugar? If not, its just a craving for foods you love which tend to be hyperpalatable. Hell, i have been craving Outback for 2 weeks now. And that is steak and potatoes with just butter.

I should have said Junk Carbs laced with Sugar.

The body is actually quite good at storing glucose as fat, except in diabetics. Carbohydrates are turned into glucose by the body, quickly for simple sugars, more slowly for complex carbohydrates and sugars that are eaten with fiber, fat, or protein. Sustained high levels of glucose in the blood causes damage to nerves and the vascular system, leading to blindness and necrosis. Fortunately the body uses insulin to prevent glucose from causing damage. Insulin causes the liver and muscles to take up glucose and store it. You can store about 100g of glucose in the liver and 500g glucose (in the form of glycogen) in the muscles. Once your immediate need for glucose is met (i.e. your brain will use 120g/day), and the storage room inside your muscles and liver is full, insulin causes any excess glucose to be stored in fat cells. You do not need to eat kilos of sugar in one sitting to gain fat from it. Even if you come to a meal competely starved, with your muscles and liver absolutely empty of glycogen, you will have excess glucose after 600 grams. And, of course, your body would never let you have absolutely no glucose, as it is necessary for your brain to keep running. When the body is starved of carbohydrate, it begins to make protein into glucose, breaking down muscle if it has no other source. Fat can also be made into glucose, but it is a slow process. The body can make fat out of any excess calories that it can digest (i.e. fat, protein, and carbohydrates, excluding insoluable fiber).0 -
Heh, my sugar count also is not what is 'recommended' but it is all natural sugars because I eat a lot of fruit so I guess its just fine as long as its not added sugar. (:0

You can gain weight with natural sugars as well as added sugars. The only reason it's harder is most fruits are low in calories.

Fat gets stored and released all the time, after eating we store most of what we ate for later use otherwise we would be eating all the time (which some people do seem to do).

^^This... Foods with added sugar generally have more calories and are easier to over-eat. It really is not all that complicated.

We aren't talking about acute changes. We are talking about overall net changes in fat storage.0 -

It really isn't that good. While I admit I may have exaggerated the number slightly, let's go ahead and use 600 grams of storage, plus the 130 grams the brain uses. That's still 730 grams. That's still almost 3000 calories worth of sugar before it gets converted to fat.
Over 85% of the fat in adipose tissue is made of fatty acids. Sugar is very rarely stored, because it's used immediately.0 -

Yes, the sugar is turned by the liver into fatty acids by the body so it can be stored in fat cells. And, as you acknowledged above, that happens continuously over the day. Sugar, in some ways, is more likely to be stored as fat, as it has no other use in the body other than stored and used energy. Fat and protein both are used to make hormones, in the nervous system, to repair and build body tissues, in the skin, etc. (have a use beyond their caloric content).
There is only a net gain of fat when the body is given more calories than daily energy expenditure, however, as we live in a society with over 50% of people being overweight or obese, this is not a rare event. Having one`s liver and muscles completely empty at the beginning of a meal is extremely rare, however, unless carbs are restricted. Keep in mind the 130 g of carbs the brain uses is over the course of a day. For the 1/2 hour of a meal, only 5-6g carbs would be needed.
This is how carbs become net fat. If someone had their body full of stored carbs at breakfast, then ate a 500 calorie lunch, with a tdee of 2400 calories, they would have the room to store 400 calories (100 calories burned/hour at normal activity at this TDEE). So, assuming they ate 58% carbs (72g), 30% fat (17g) and 22% protein (15g - numbers slightly off due to rounding), the person would be gaining net fat in from the carbohydrate and some of the fat, with the remaing fat and all protein going to create and maintain body systems (non-energy requirements). Some of the carbs would be sugar, so sugar made fat in this example, perhaps as little as the 10 grams in a glass of juice. Sugar is turned into net fat regularly.0 -

Carbohydrates are turned into glucose by the body, quickly for simple sugars, more slowly for complex carbohydrates and sugars that are eaten with fiber, fat, or protein. Sustained high levels of glucose in the blood causes damage to nerves and the vascular system, leading to blindness and necrosis. Fortunately the body uses insulin to prevent glucose from causing damage. Insulin causes the liver and muscles to take up glucose and store it. You can store about 100g of glucose in the liver and 500g glucose (in the form of glycogen) in the muscles. Once your immediate need for glucose is met (i.e. your brain will use 120g/day), and the storage room inside your muscles and liver is full, insulin causes any excess glucose to be stored in fat cells. You do not need to eat kilos of sugar in one sitting to gain fat from it. Even if you come to a meal competely starved, with your muscles and liver absolutely empty of glycogen, you will have excess glucose after 600 grams. And, of course, your body would never let you have absolutely no glucose, as it is necessary for your brain to keep running. When the body is starved of carbohydrate, it begins to make protein into glucose, breaking down muscle if it has no other source. Fat can also be made into glucose, but it is a slow process. The body can make fat out of any excess calories that it can digest (i.e. fat, protein, and carbohydrates, excluding insoluable fiber).
I was replying to tigger who claimed you would have to eat over a kilo of sugar at one sitting for any of it to be stored as fat, and that sugar is rarely stored as fat. I was giving an extreme "at one sitting" example, I didn't really cover the "over maintenance" part (except for people with a tdee under 2400 calories). In reality, every calorie of sugar consumed over maintenance can be converted and stored as fat, I agree0 -

I watched a really interesting documentary yeaterday though called Fed Up. According to that, sugar calories (all sugars, natural or processed) aren't treated by your body the same way and are more readily stored as fat instead of used as energy. It is worth watching if you would like to learn more about sugar in your diet.
No. The sugars are treated exactly the same way, as they are the exact same molecules. The human digestive system doesn't recognize "Apple" or "Twinkie." It recognizes glucose and fructose and digests them accordingly.
Also, unless you're eating kilograms of sugar, it won't be stored as fat. Sugar is almost never stored as fat, as the body readily uses it as its main energy source. It won't remain in the body long enough to be converted to fat, unless, like I said, you're eating about a 1000 grams in a sitting. That would be the equivalent of 25 cans of Coke in one sitting, for perspective.

It really isn't that good. While I admit I may have exaggerated the number slightly, let's go ahead and use 600 grams of storage, plus the 130 grams the brain uses. That's still 730 grams. That's still almost 3000 calories worth of sugar before it gets converted to fat.
Over 85% of the fat in adipose tissue is made of fatty acids. Sugar is very rarely stored, because it's used immediately.
Yes, the sugar is turned by the liver into fatty acids by the body so it can be stored in fat cells. And, as you acknowledged above, that happens continuously over the day. Sugar, in some ways, is more likely to be stored as fat, as it has no other use in the body other than stored and used energy. Fat and protein both are used to make hormones, in the nervous system, to repair and build body tissues, in the skin, etc. (have a use beyond their caloric content).
There is only a net gain of fat when the body is given more calories than daily energy expenditure, however, as we live in a society with over 50% of people being overweight or obese, this is not a rare event. Having one`s liver and muscles completely empty at the beginning of a meal is extremely rare, however, unless carbs are restricted. Keep in mind the 130 g of carbs the brain uses is over the course of a day. For the 1/2 hour of a meal, only 5-6g carbs would be needed.
This is how carbs become net fat. If someone had their body full of stored carbs at breakfast, then ate a 500 calorie lunch, with a tdee of 2400 calories, they would have the room to store 400 calories (100 calories burned/hour at normal activity at this TDEE). So, assuming they ate 58% carbs (72g), 30% fat (17g) and 22% protein (15g - numbers slightly off due to rounding), the person would be gaining net fat in from the carbohydrate and some of the fat, with the remaing fat and all protein going to create and maintain body systems (non-energy requirements). Some of the carbs would be sugar, so sugar made fat in this example, perhaps as little as the 10 grams in a glass of juice. Sugar is turned into net fat regularly.
Carbs are rarely, if ever stored as fat. DNL? The dietary fat you eat is the easiest to store0 -

Oh, did I misunderstand CICO? I can eat 3000 calories at each meal and not gain fat as long as it is all sugar? Good news. I found out what I've been doing wrong all this time...LOL (sorry, I just couldn't resist )0
