Be sure to drink plenty of water. It is recommended to drink a minimum of 8 glasses each day. If your blood glucose is 250 or greater and you are on insulin, check your urine for ketones. If you have ketones, follow your sick day rules or call your healthcare team if you are not sure what to do. Ask yourself what may have caused the high blood sugar, and take action to correct it. Ask your healthcare team if you are not sure what to do. Try to determine if there is a pattern to your blood glucose levels. Check your blood glucose before meals 3 days in a row. If greater than your target level for 3 days, a change in medication may be needed. Call your healthcare team or adjust your insulin dose following well day rules. Call your healthcare team if you are currently using diabetes pills. Ask yourself the questions outlined below. The answers will give you the information you need to determine what to do about the hyperg Continue reading >>

    Why can't fat be converted into Glucose?

    So the reason cited is that beta oxidation/metabolism of fats leads to formation of acetyl coa, a 2 carbon molecule, and that because of that it cannot be converted back into glucose.
    Why exactly is that the case?
    If Glucogenic amino acids can be converted into citric acid cycle intermediates and then turn back into glucose via gluconeogensis, then why cant Fatty Acids which yield Acetyl Coa. Can't you just have Acetyl Coa enter the citric acid cycle and produce the same intermediates that the glucogenic amino acids creat?

    Click to expand... Both glucose and fatty acids can be stored in the body as either glycogen for glucose (stored mainly in the liver or skeletal cells) or for FA's, as triacylglycerides (stored in adipose cells). We cannot store excess protein. It's either used to make other proteins, or flushed out of the body if in excess; that's generally the case but we try to make use of some of that energy instead of throwing it all away.
    When a person is deprived of nutrition for a period of time and glycogen stores are depleted, the body will immediately seek out alternative energy sources. Fats (stored for use) are the first priority over protein (which requires the breakdown of tissues such as muscle). We can mobilize these FA's to the liver and convert them to Acetyl-CoA to be used in the TCA cycle and generate much needed energy. On the contrary, when a person eats in excess (a fatty meal high in protein), it's more efficient to store fatty acids as TAG's over glycogen simply because glycogen is extremely hydrophilic and attracts excess water weight; fatty acids are largely stored anhydrously and so you essentially get more bang for your buck. This is evolutionary significant and why birds are able to stay light weight but fly for periods at a time, or why bears are able to hibernate for months at a time. Proteins on the other hand may be used anabolically to build up active tissues (such as when your working out those muscles), unless you live a sedentary lifestyle (less anabolism and therefore, less use of the proteins). As part of the excretion process, protein must be broken down to urea to avoid toxic ammonia and in doing so, the Liver can extract some of that usable energy for storage as glycogen.
    Also, it is worth noting that it is indeed possible to convert FA's to glucose but the pathway can be a little complex and so in terms of energy storage, is not very efficient. The process involves converting Acetyl-CoA to Acetone (transported out of mitochondria to cytosol) where it's converted to Pyruvate which can then be used in the Gluconeogenesis pathway to make Glucose and eventually stored as Glycogen. Have a look for yourself if your interested: http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002116.g003/originalimage (and this excludes the whole glycogenesis pathway, which hasn't even begun yet).
    TLDR: it's because proteins have no ability to be stored in the body, but we can convert them to glycogen for storage during the breakdown process for excretion. Also, in terms of energy, it's a more efficient process than converting FA's to glycogen for storage.

    This is where biochem comes in handy. Czarcasm gives a really good in depth answer, but a simpler approach is to count carbons. The first step of gluconeogenesis(formation of glucose) requires pyruvate, a 3 carbon molecule. Acetyl Co-A is a 2 carbon molecule, and most animals lack the enzymes (malate synthase and isocitrate lyase) required to convert acetyl co-A into a 3 carbon molecule suitable for the gluconeogenesis pathway. The ketogenic pathway is not efficient, as czarcasm pointed out. While acetyl co-A can indeed be used to form citric acid intermediates, these intermediates will be used in forming ATP, not glucose. Fatty acid oxidation does not yield suitable amounts of pyruvate, which is required for gluconeogenesis. This is part of why losing weight is fairly difficult for those that are overweight, we can't efficiently directly convert fat to glucose, which we need a fairly constant supply of. Sorry, that got a little long-winded

Hyperglycemia is the term given to when your blood sugar levels are higher than 10 mmol/L. Blood sugar levels levels exceeding 7 mmol/L can damage internal organs, however, symptoms may not develop until blood glucose levels exceed 15 mmol/L so it's worth knowing about the symptoms of hyperglycemia and how to recognise the symptoms.

Hyperglycemia: Symptoms, Causes, Diagnosis, And Treatment

Glucose can build up in the blood when the body doesn't produce enough insulin, a hormone that acts as a sort of key to unlocking cells so glucose can get inside them. Themedical term for this is called hyperglycemia (high blood glucose) and refers to higher than normal levels of glucose (sugar) in the bloodabove 200 milligrams per deciliter (mg/dl). For otherwise healthy people 59 and under, a normal blood sugar range is between 80 and 120 mg/dL. And, forthose who are 60 and older, the normal range is between 100 and 140 mg/dL. Hyperglycemia is a symptom of both type 1 diabetes and of type 2 diabetes. In other words, it's one of the factors that cause a person to be diagnosed with either condition. It is also a complication of the two forms of diabetes. This means that once a diagnosis is made and a person has begun to successfully manage their diabetesmeaning they've lowered their blood sugar to a normal levelhyperglycemia can be a sign that there's actually a problem with the treatment protocol. Other conditions can also be associated with elevated blood sugar levels. But, regardless of what might cause hyperglycemia, the symptoms essentially will be the same. Either way, if bl Continue reading >>

    I wasn’t sure which section I should post this in, my strategy is what I call the 4–2–1 plan, I fast 2 day non consecutive days a week, eat a low carb but not calorie restricted diet 4 days a week to keep the fat burning benefits of ketosis going and then I give myself 1 day a week to indulge and eat whatever I want, usually a Saturday pasta dinner and wonderful dessert. I also walk 4 to 6 miles a day during the week and 10 to 12 miles on Saturday.
    Low Carb plans such as Atkins can be very effective for some people including me, many people who start a low carb diet experience get what’s called the “ketosis flu” or the “induction flu” in the first few days while the body is adapting to burning ketones instead of glucose.
    The basic symptoms are:
    – Headaches
    – Nausea
    – Upset stomach
    – Lack of mental clarity (brain fog)
    – Sleepiness
    – Fatigue
    It’s called the “ketosis flu” for a reason: you feel sick. I’ve gone through it and it wasn’t a pleasant experience. Fortunately it only lasted 2 days but then suddenly I woke up feeling much better, less hungry and my energy level was really high and consistent throughout the day!
    The first time I thought to myself: “What the heck am I doing? I feel like I’m going to die!” but I persevered and when it was over I didn’t regret a thing because what I had gained mentally and physically was 100% worth it.
    For those of you that are going through the ketosis flu, don’t give up! I know you feel like it’s never going to get better but stick with it and you´ll be so happy you did! I’m telling you, waking up refreshed for the first time in years, not getting the afternoon “blah” feeling and stuffing my face with carbs to try to boost my energy is the best side effect of the low carb diet I’ve experienced. Okay, losing weight while eating good food, feeling full and satisfied is great too.
    First you have to understand why your body is reacting this way. Your body’s been burning glucose for energy so it’s basically full of enzymes that are waiting to deal with the carbs you eat, but now the body needs to make new enzymes that burn fat for fuel instead of carbs, and the transition period causes the flu-like symptoms.
    There are some things you can do to lessen the symptoms of the ketosis flu and to make it go away sooner (to force the body to transition sooner) Ok, let’s get to the good part – what to do:
    First of all – you’re probably dehydrated. Drink PLENTY of water while you’re on a low carb diet, and then drink some more.
    Watch your electrolytes. When the body is getting rid of excess insulin from your former carb-crazy diet you´ll lose lots of fluids that have been retained in your body. This causes the rapid weight loss most people see in their first few days of ketosis, it’s mostly water, sorry. When you lose all the retained water you also lose electrolytes like sodium, magnesium and potassium. When you’re lacking them you´ll feel like crap so when you’re feeling really ill on the ketosis flu try things like chicken/beef broth and look for foods rich in these minerals. Take a multi-vitamin and a multi-mineral.
    Ok, here is where people throw the red flag – Eat more fat – Yup, I said MORE fat. Have some butter, just not on a roll, eat some bacon and eggs for breakfast, just skip the potatoes and toast. This will force your body to hurry up the transition. You´ll think this is crazy and think you´ll never get lose weight eating this way, but you will.
    Don’t eat too much protein – The body can transform protein into glucose so if you eat too much of it in the first days it will slow down the transition. Go for fatty meat and cheese if you can, add fat to protein shakes etc.
    Drink water, replenish electrolytes (sodium, magnesium, potassium) with food and supplements, drink broth, eat fat and not too much protein.
    I hope this helps, and have a great day

    ” Take a multi-vitamin and a multi-mineral.”
    I have been forgetting to take a multi-vitamin on fast days. Thanks for the reminder.
    “Eat more fat – Yup, I said MORE fat. ”
    I will have avocado more often.

Hyperglycemia (high Blood Sugar)

Review your blood sugar logs to look for patterns of BG over 140-150 mg/dL. A very high BG is anything over 300 mg/dL. One very high blood sugar number, as long as you feel okay, is not an immediate cause of concern. 2 or more very high blood sugar numbers means you need to start figuring out why your number is so high. Test for ketones when you have more than two very high blood sugar numbers in a row. In general, any level over 140-150 mg/dL is a high level. You do not necessarily need to do anything about this level beyond watching to make sure that a pattern of levels at or above this range doesnt develop. If you notice that your BG levels are rising, you can call the diabetes clinic for some help in making changes to fix these levels. At some point everyone with diabetes will have a very high blood sugar level. We define very high as any level over 300 mg/dL. One very high blood sugar level is not a cause for panic. Rather, it should serve as an alarm signaling the need for additional blood glucose monitoring and depending upon how you treat your diabetes; it may also mean that you need to take some extra insulin. Very high blood sugar levels mean that the body does not have Continue reading >>

    Hey everyone, took all your suggestions from the last post to bring you a better keto calculator. Last thread here.
    Major Changes:
    1. Adjusted Protein Levels - everyone seems to like .8 grams so that's the new default!
    2. Revamped Activity Levels - original ones were far too broad so came up with more realistic options.
    3. Forecast Added - you can now quickly check your predicted weight loss.
    Other than that just some minor UI tweaks. Again, hope you all like it!

  2. Triabolical_

    Have you thought about expressing the fats as a range?
    We have a continuous stream of people new to keto who think that they have to get their full fat macro in, when in fact they can eat a lot less fat than that.
    It might also be nice to express this as "limit, goal, limit" under the values for carbs, protein, fats.

  3. FunkeeSapien

    Haven't thought about doing a range (since it gives you exactly how much deficit you want to do, and if you want to lose faster you can just choose a lower deficit), but including "goal, limit, limit" would be a nice addition.
    You're right it might help newer people, I'll experiment with that thanks.
