    > How can I stop the Atkin's related hair loss?

    When I lost 48 lbs on Atkins in 2003, I lost quite a bit of hair. I'd say maybe 2/3 of my hair fell out. When I went to my hairdresser to get a trim, she was agast as she combed out my hair (and it came out in her hands) and thought I had something really wrong with me. I did a lot of research on why this was happening to me and the answer that I came up with was that whenever your body has a severe shock to it's system, like a bad allergic reaction, or, lol, losing a lot of weight very quickly, you will lose your hair. Now, my hair got pretty thin, but it did come back. I remember feeling the new growth coming in. I'm back on Atkins now, and the weight is coming off just as quickly as it did before, so now I'm hoping to avoid the hair loss this time around. Now, here's my questions--
    1. A friend of mine told me that she lost hair while on Atkins too, and that it didn't come back as thick--Has anyone experienced this?
    2. Is there anything I can do or take, ie. supplements, extra vitamins, to prevent or lessen the hair loss? Has anyone actually had any luck with anything?

  2. LiveWell

    Just keep taking your suppliments, just as you read the hair loss is about shocking the body. I dont really think there is anything you can do about it. My hair has been shedding for my entire life so it doesnt really bother me that much. I know it will grow back just fine.


    NO SH*T!!??? OMG....I need to hold onto every piece of hair I have lol.....never heard of this from any others and I've been reading here for a few years. This must happen, but it must be affect only a small amount??? I would just add like the last post to keep taking your vitamins, and maybe even see a person w/ ALOT of knowledge of vitamins/nutrients/nutrition/etc---and that's quite often NOT a physician believe it or not!!

    Can someone very generally describe how the brain consumes ketoacids/ketone bodies when blood glucose has been completely depleted?

  2. Jayachandran

    Human body is a glucose driven machine which intake carbohydrates and converts to glucose. Energy is yielded from the glucose and glucose is stored as glycogen. When the carbohydrate intake is somehow reduced then body will shift its mechanism and uses the fatty acids to produce energy. Liver synthesis ketones from fatty acids in our diet or from body fat. Ketones(acetoacetate and acetone) are released into the blood, which is absorbed by the brain and synthesis energy from it through their mitochondria.
    The brain gets a portion of its energy from ketone bodies when glucose is less available (e.g., during fasting, strenuous exercise, low carbohydrate, ketogenic diet and in neonates). In the event of low blood glucose, most other tissues have additional energy sources besides ketone bodies (such as fatty acids), but the brain has an obligatory requirement for some glucose. After the diet has been changed to lower blood glucose for 3 days, the brain gets 25% of its energy from ketone bodies.After about 4 days, this goes up to 70% (during the initial stages the brain does not burn ketones, since they are an important substrate for lipid synthesis in the brain). Furthermore, ketones produced from omega-3 fatty acids may reduce cognitive deterioration in old age. Reference
    When the body starts using the fatty acids for energy production, one problem arises in the brain and that is the blood-brain barrier( barrier that separates the circulating blood from the brain extracellular fluid in the central nervous system )Brain cannot use long chain fatty acids because they cannot cross the blood-brain barrier due to their bondage with albumin. As ketones are medium chain fatty acids which can effectively cross the barrier. So brain uses the ketones for energy production by a process called as ketosis. The ketone bodies are then incorporated into acetyl-CoA and used in the citric acid cycle.
    The citric acid cycle – also known as the tricarboxylic acid (TCA) cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).

    Actually there is fatty acid transport through the BBB. Maybe the rate of this transport is not enough, I don't know, I think it does not really matter.
    What really happens here, that the liver prepares the fatty acids, so the brain can use them more easily in the form of ketoacids to produce energy.

An Integrated Analysis Of Glucose, Fat, And Protein Metabolism In Severely Traumatized Patients. Studies In The Basal State And The Response To Total Parenteral Nutrition.

University Department of Surgery, Auckland Hospital, New Zealand. A series of isotopic infusions were performed in 43 severely ill patients suffering from blunt trauma (mean injury severity score of 31). The patient data have been compared with data obtained from 32 normal volunteers, and in addition the metabolic response of the trauma patient to total nutritional support (TPN) has been assessed. The rate of VO2 was elevated in the trauma patients compared with that of the volunteers (160 mumol/kg/minute vs. 103 mumol/kg/minute). Glucose production was significantly increased in the patients compared with the volunteers (21 +/- 2 mumol/kg/minute vs. 14 +/- 1 mumol/kg/minute), but the trauma patients had an impaired capacity to directly oxidize plasma glucose. The percentage of glucose uptake oxidized in the volunteers was 36 +/- 2%, and the percentage of glucose uptake recycled was 10 +/- 1%. By contrast, in the trauma patients, 23 +/- 4% of the glucose uptake was directly oxidized, and 29 +/- 11% was recycled. The rate of glycerol turnover in the trauma patients (5.3 +/- 0.3 mumol/kg/minute) was significantly elevated compared with the volunteer value (2.2 +/- 0.1 mumol/kg/minut Continue reading >>

    It varies for everyone. For me personally...it took 4 days to register anything and almost 2 weeks to get purple...I have never seen the darkest purple shade. Some people will tell you not to use the sticks, but I like them. My doctor told me to use them 3 times a day for a week to see when my body is the highest. Again...everyone is different. I am highest in the morning, but I hear some people are highest at night.

    Your body has to burn off all the stored sugar before it goes into ketosis. The shade on the stick should read ' moderate. ' Any higher means you aren't drinking enough water to flush out excess ketones. Too many ketones in your body is unhealthy. So don't think you have to be in the darkest purple range to be eating properly. Also the best time to test is first thing in the morning. Only diabetics need check more than once a day. On atkins we don't even need to use keto sticks. If you follow the rules you will be in ketosis.

    The present status of protein synthesis within cells has been outlined. Protein is formed in the absence of insulin; the net formation of protein is accelerated by insulin.

In the case of protein metabolism, as in certain studies on the pat ...
