Copyright 2009, American Physiological Society This article has been cited by other articles in PMC. Four grams of glucose circulates in the blood of a person weighing 70 kg. This glucose is critical for normal function in many cell types. In accordance with the importance of these 4 g of glucose, a sophisticated control system is in place to maintain blood glucose constant. Our focus has been on the mechanisms by which the flux of glucose from liver to blood and from blood to skeletal muscle is regulated. The body has a remarkable capacity to satisfy the nutritional need for glucose, while still maintaining blood glucose homeostasis. The essential rol Continue reading >>

    How long can I stay in Ketosis

    Hey guys, I've done Keto in the past where I'd refeed on Saturdays, then back to Low Carb on Sundays until Friday, then refeed again Saturday.
    At the time I was doing strongman and I wanted to keep my strength/muscle mass.
    Right now I am doing Muay Thai and BJJ. I work out like 2-3 hrs a day. I just want to lose as much weight as possible and as quickly possible. I am not too worried about losing "too much weight" in a week because I know my conditioning will improve as I get skinnier.
    So, I am wondering how long can I go before I have to refeed? I know the brain needs glucose to function, so I am worried about going on for too long. So far I've been in Ketosis state since Tuesday morning when I woke up.
    Thanks

    The brain can do just fine on the glucose your body harvests from dietary protein, that's not what carb ups are for. Carbs ups are a reset switch for important metabolic hormones like leptin and T3. Some people do well for weeks on end in ketosis; I'm certainly not one of those people. Plus, the added physiological benefits of a weekly carb up are more than worth it.

    if my understanding is correct, the more bf your carrying the longer you can go before your body starts catabolizing lean mass for carbs. I think some people have done SKD(straight keto diet) for months on end without much lm loss as long as they watch their activity and such.
    now you being a combative athlete does change the figure(I do the MT/BJJ route as well). I seem to preserve lm better when taking my BCAA supps, plenty of sleep, and getting about 2 tbs coconut oil a day.

Glycogen And Diabetes - Role, Storage, Release & Exercise

Glycogen is a stored form of glucose. It is a large multi-branched polymer of glucose which is accumulated in response to insulin and broken down into glucose in response to glucagon . Glycogen is mainly stored in the liver and the muscles and provides the body with a readily available source of energy if blood glucose levels decrease. Energy can be stored by the body in different forms. One form of stored energy is fat and glycogen is another. Fatty acids are more energy rich but glucose is the preferred energy source for the brain and glucose also can provide energy for cells in the absence of oxygen, for instance during anaerobic exercise. Glycogen is therefore useful for providing a readily available source of glucose for the body. In a healthy body, the pancreas will respond to higher levels of blood glucose , such as in response to eating, by releasing insulin which will lower blood glucose levels by prompting the liver and muscles to take up glucose from the blood and store it as glycogen. People with diabetes either do not make enough of their own insulin and/or their insulin does not work effectively enough. As a result, the pancreas may not be able to respond effectively Continue reading >>

    High Fat diet causes insulin resistance??

    Are these guys saying that High Fat diets cause insulin resitance?
    http://care.diabetesjournals.org/con...4/11/1911.full

    Dietary fat has long been considered a potentially important modifiable risk factor for diabetes. The evidence for an adverse effect of high total fat and high saturated fat intake on blood glucose levels in nondiabetic populations is quite consistent, whereas the evidence for an effect of polyunsaturated fat intake is less clear (
    1). Positive associations have been found between the risk of type 2 diabetes or hyperglycemia and total fat intake in both prospective (2,3) and cross-sectional (4,5) studies. Positive associations have also been found with saturated (3,6,7) and animal (8) fat and meat (9) intake. A positive association was reported between polyunsaturated fat intake and hyperglycemia in the Hoorn Study (10), although a reduced risk of type 2 diabetes was associated with increased vegetable fat intake (11) and polyunsaturated fat intake (12) in the U.S. Nurses’ Health Study. Eating fish, which is high in n-3 polyunsaturated fat, has a beneficial effect on glycemia (13,14). In a number of other studies, there were no reported associations with dietary fat intake (15,16,17,18,19).

    i've been attending a diabetes class offered by the local seventh day adventist wellness clinic. they 'preach' that a diet high in animal fat is one of the leading causes of t2. they believe that the fat 'coats' the insulin receptors and blocks the insulin from opening up the cell so that glucose can enter.
    they also say that by eating a vegan diet, along with exercise, a person can 'reverse' their t2 diabetes since this will 'cleanse' the body of that unwanted fatty coating on the insulin receptors.
    needless to say, i'm not quite ready to switch to totally vegan. but i will continue to eat more veggies

    I have read that it blocks the receptors too. Thanks for mentioning that.

How Our Bodies Turn Food Into Energy

All parts of the body (muscles, brain, heart, and liver) need energy to work. This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy. Without insulin, glucose stays in the bloodstream, keeping blood sugar levels high. Insulin is a hormone made by beta cells in the pancreas. Beta cells are very sensitive to the amount of glucose in the bloodstream. Normally beta cells check the blood's glucose level every few seconds and sense when they need to speed up or slow down the amount of insulin they're making and releasing. When someone eats something high in carbohydrates, like a piece of bread, the glucose level in the blood rises and the beta cells trigger the pancreas to release more insulin in Continue reading >>

    Yes. Alcohol is a sugar, and so it will stop ketosis. But I have also done this diet to great success, and I find that as long as alcohol is the only carb in your system, the ketosis will return as soon as you have metabolized the alcohol. But, if you eat carbs along with the alcohol, those carbs my be turned to fat while your body metabolizes the alcohol.

  2. Doug Freyburger

    In this context the alcohol does not matter. Beers run roughly 20 grams of carb each unless a specifically low carb variety like Guinness. The level of 50 per day net is the point most drop out of ketosis. It's the bottom level for maintenance. The level of 100 per day net has nearly everyone out of ketosis. It'sthe top level for maintenance for most.

  3. SIMON RICHARDSON

    Yes more than likely. There’s a lot of carbs in beer .Thats why its sometimes called liquid bread. Look at drinking red wine instead which only has about 2 g of carbs per average glass but limit that to one or two.

  • Glucose Stored As Fat

    Your body uses mostly carbohydrates as well as fats for energy. Because the body doesn’t store carbs efficiently, they’re used first. Carbohydrates turn into glucose, which your body burns immediately or converts to glycogen to be stored in the muscles and liver for between meals. If you eat more calories from carbs or other sources than your body can use, the cells store the excess as fat. Of the three major nutrients -- carbohydrates, fat a ...

    In the last section, we learned how fat in the body is broken down and rebuilt into chylomicrons, which enter the bloodstream by way of the lymphatic system. Chylomicrons do not last long in the bloodstream -- only about eight minutes -- because enzymes called lipoprotein lipases break the fats into fatty acids. Lipoprotein lipases are found in the walls of blood vessels in fat tissue, muscle tissue and heart muscle. Insulin When you eat a candy ...
