Professor Timothy Noakes (born 1949) is a South African professor of exercise and sports science at the University of Cape Town. He has run more than 70 marathons and ultramarathons and is the author of several books on exercise and diet. He is known for his support of a high-fat, low-carbohydrate diet, as set out in his book The Real Meal Revolution.

Low-carbohydrate Diets: Nutritional And Physiological Aspects.

Low-carbohydrate diets: nutritional and physiological aspects. Cerestar R&D Vilvoorde Center, Havenstraat 84, 1800 Vilvoorde, Belgium. Recently, diets low in carbohydrate content have become a matter of international attention because of the WHO recommendations to reduce the overall consumption of sugars and rapidly digestible starches. One of the common metabolic changes assumed to take place when a person follows a low-carbohydrate diet is ketosis. Low-carbohydrate intakes result in a reduction of the circulating insulin level, which promotes high level of circulating fatty acids, used for oxidation and production of ketone bodies. It is assumed that when carbohydrate availability is reduced in short term to a significant amount, the body will be stimulated to maximize fat oxidation for energy needs. The currently available scientific literature shows that low-carbohydrate diets acutely induce a number of favourable effects, such as a rapid weight loss, decrease of fasting glucose and insulin levels, reduction of circulating triglyceride levels and improvement of blood pressure. On the other hand some less desirable immediate effects such as enhanced lean body mass loss, increas Continue reading >>

    Hey Guys,
    How do you deal with bad breath on cd ss, i need to find a way to better my stinky mouth befor i go back 2 uni as i do value my friends and would like to keep them....:ignore:
    i was thinking about sugar free gum but wasnt sure if we were allowed those? plus mints and sprays??
    if we are allowed which brands are we allowed and were can i get them????
    thanks for helping xxxxxxxxxx

    It's a problem, right? When I started SS in late November I went everywhere with listerine, toothpaste & a toothbrush in my bag, and kept making sudden sprints for the loos, I was so paranoid! My cdc said chewing gum was out, & couldn't find breath freshener spray in our local area. It does get easier after a few weeks - less of a problem, but I'm restarting SS and the bad breath is back... grrr!!! I do know others have used zero cal gum and also listerine strips... not sure what they are, but sound good. I really was self-conscious about this and developed a habit of trying to talk from behind my hand, not exactly subtle!!! Look forward to seeing how other people have coped... better than me, I bet!!!

    hey!
    from other posts on here it looks like chewing gum (make sure it is peppermint or something because citric is very bad!) and you can chew it for one or two minutes. some people say you can chew for longer, but it will make you hungry or something? so people seem to think it is best to be sticking to the breath fresheners and listerine tabs.
    have you noticed that you have a horrible taste in your mouth? i have and it is so horrible so i keep drinking water to try and get rid of it but it is not going!! (i'm on day two) and does your jaw hurt? mine feels quite tight, don't know if that is diet related or not though!!

What is INSULIN RESISTANCE? What does INSULIN RESISTANCE mean? INSULIN RESISTANCE meaning - INSULIN RESISTANCE definition - INSULIN RESISTANCE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Insulin resistance (IR) is a pathological condition in which cells fail to respond normally to the hormone insulin. The body produces insulin when glucose starts to be released into the bloodstream from the digestion of carbohydrates in the diet. Normally this insulin response triggers glucose being taken into body cells, to be used for energy, and inhibits the body from using fat for energy. The concentration of glucose in the blood decreases as a result, staying within the normal range even when a large amount of carbohydrates is consumed. When the body produces insulin under conditions of insulin resistance, the cells are resistant to the insulin and are unable to use it as effectively, leading to high blood sugar. Beta cells in the pancreas subsequently increase their production of insulin, further contributing to a high blood insulin level. This often remains undetected and can contribute to a diagnosis of type 2 diabetes or latent autoimmune diabetes of adults. Although this type of chronic insulin resistance is harmful, during acute illness it is actually a well-evolved protective mechanism. Recent investigations have revealed that insulin resistance helps to conserve the brain's glucose supply by preventing muscles from taking up excessive glucose. Insulin resistance should even be strengthened under harsh metabolic conditions such as pregnancy, during which the expanding fetal brain demands more glucose. People who develop type 2 diabetes usually pass through earlier stages of insulin resistance and prediabetes, although those often go undiagnosed. Insulin resistance is a syndrome (a set of signs and symptoms) resulting from reduced insulin action; it is also part of a larger constellation of symptoms called the metabolic syndrome. Insulin resistance may also develop in patients who have recently experienced abdominal or bariatric procedures. This acute form of insulin resistance that may result post-operatively tends to increase over the short-term with sensitivity to insulin typically returning to patients after about five days.

Physiological Insulin Resistance

Back in mid summer 2007 there was this thread on the Bernstein forum. Mark, posting as iwilsmar, asked about his gradual yet progressively rising fasting blood glucose (FBG) level over a 10 year period of paleolithic LC eating. Always eating less than 30g carbohydrate per day. Initially on LC his blood glucose was 83mg/dl but it has crept up, year by year, until now his FBG is up to 115mg/dl. Post prandial values are normal. He wanted to know if he was developing diabetes. I've been thinking about this for some time as my own FBG is usually five point something mmol/l whole blood. Converting my whole blood values to Mark's USA plasma values, this works out at about 100-120mg/dl. Normal to prediabetic in modern parlance. However my HbA1c is only 4.4%, well toward the lower end of normality and healthy. That's always assuming that I don't have some horrible problem resulting in very rapid red blood cell turnover. I don't think so... I spend rather a lot of my life in mild ketosis, despite the 50g of carbs I eat per day. So I can run a moderate ketonuric urine sample with a random post-chocolate blood glucose value of 6.5mmol/l. What is happening? Well, the first thing is that LC eati Continue reading >>

    So the last few days I have been sleeping really well. Barely got up, was able to sleep in the morning which is something I have always done, I am a night person and I like it that way. However, while I was not cheating, between all the supplements I have been taking for some aches and pains and the extra nuts I have been snacking on I suspected I was not in ketosis. Yesterday I skipped lunch unintentionally and started what is now a 40 hour fast. Last night my sleep went back to how it is on keto/fasting. I woke up several times to use the facilities and this morning woke up an hour earlier than usual and could not go back to sleep (no matter how much I wanted to). I do not feel refreshed but I do feel alert. On the flip side I usually fall asleep earlier than usual with keto.

    I have always had a bit of a delayed circadian issue but I like it and am used to it. When on keto it seems to fix it? Is that possible?

  2. David_Driver

    I am going to have to give up on Keto. I have had insomnia for almost a year and I discovered that when I cheat I sleep all night. This week I have bumped up the carbs significantly and I have slept all the way through every night. If you google low carb and insomnia you will find that it is fairly common.

  3. Loulou

    Perhaps that is why my insomnia has been so bad recently. Only slept 4 hours last night. However, if I eat more than 20 grams carbs I immediately put on 1 or 2 lbs over night which is a no no for me,

FREE 6 Week Challenge: https://gravitychallenges.com/home65d... Fat Loss Calculator: http://bit.ly/2O6rsdo The carb cycling diet is one of my favorite diets because it is one of the fastest way to burn fat while retaining as much muscle as possible. Most people don't know that carb cycling is actually a form of ketogenic dieting. The ketogenic diet is a diet that is lower in carbohydrates, which makes our body convert more dietary fat and body fat in to keytones in the liver. Which it then goes on to use for energy. Like I've said in many of my videos the human body prefers to use carbs as its primary source of energy. You're body won't produce too many keytones on a high carbohydrate diet, because your body won't need extra energy from fat due to the fact that its getting its energy from the more preferred carbohydrates. The only way for our body to use more fat for energy is by not having its preferred source there all the time. Eliminating carbs completely, however can have many drawbacks on our health and well being. Protein, carbs, and fats are all important and necessary for our body. So in comes the cyclical ketogenic diet aka carb cycling and also known originally as the anabolic Diet. There are many different approaches to carb cycling, but the general idea is that At some points of the week you're going to have a high amount of carbohydrates, and at other points of the week you're going to have a low amount of carbohydrates. Setting up the high carb and low carb splits will vary from one plan to the next. Some people may have very small changes in the amount of carbs they have from day to day. An example of this would be to set up a low carb, medium carb, and high carb day. Let's say 300 grams of carbs on high carb, 250 grams of carbs on your medium carb, and 200 grams of carbs on your no carb day. Another more advanced approach would be to do a High carb, low carb, and no carb day. The way that I like to set this kind of split up is by having a high amount of carbs on my high carb day, which for me would be somewhere around 400 grams, I would have one third or at the most half that amount for low carb day, and then try to get as close to 0 grams as possible on my no carb day and then repeat. An even more advanced approach would be to just cycle between high and no carb days. Or take it even a step further and do high, no, no. I don't really recommend having any more than two no carb days in a row. Make sure you don't jump to any extreme carb restrictions. An example of this is doing a 800 calorie diet when you could lose weight and maintain a better body composition with a 1500 calorie diet. Jumping to an extreme will not help you lose weight faster, in fact it'll probably backfire. Also in case you're wondering what kind of food you can eat on your no carb day, some great options are fish, chicken breast, ground turkey, protein shakes, Steak occasionally, and you can also have healthy fat sources like avocados, coconut oil, olive oil. and fatty fish like Salmon. For carbs make sure you are eating good sources of carbs like oats, brown rice, and sweet potatoes and avoid the junk food carbs. You can incorporate one cheat meal on one high carb day in the week, but that's it one cheat meal. You may notice that your strength and energy levels may go down while dieting like this. In fact you may feel like straight up garbage in the beginning. Understand that a lot of people feel this way when creating any kind of a calorie deficit. You're body will take a little while to adapt to using fat for energy instead of carbs. So the first 2 weeks can feel miserable. Give your body some time to adapt. A good idea is to plan your high carb days the day before a heavy lifting day, because this way you have stored glycogen available for your heavy lifts the next day. If you have no idea how many carbs to have on each day, try using a calorie calculator to find your maintenance macros and then add at least 50 grams of carbs to get the number for your high carb day. I'll include a calorie calculator in the description. Once you have your high carb number you should be able to figure out your low carb day. No carb day is obviously no carbs. After doing a carb cycling plan you may need to do some reverse dieting

The Ketogenic Diet And Insulin Resistance

We recently touched on how you can use the ketogenic diet to control symptoms of diabetes such as elevated glucose and triglycerides. In this article, we examine research showing the impact that the ketogenic diet has on levels of the hormone insulin, a key regulator of blood sugar in the body. What is Insulin’s Role in the Body? Before we look at the research, we need to know our main players. Insulin is a protein-based hormone produced by beta-cells located in the pancreas. The pancreas, which is located under the stomach, also produces enzymes that aid with digestion. Insulin’s primary purpose is to regulate the metabolism of fats and carbohydrates. The digestive system breaks down carbohydrates, such as sugars and starches, into a molecule called glucose. This compound can be used by cells to produce energy through a process called cellular respiration. Insulin allows cells in the body absorb glucose, ultimately lowering levels of glucose in the blood stream. After a meal is consumed, blood glucose levels increase and the pancreas responds by releasing insulin into the blood. Insulin assists fat, liver, and muscle cells absorb glucose from the blood, resulting in lower leve 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.
