How is it that people who are doing what they are “supposed” to be doing –- eating healthy, exercising, maintaining a normal body composition -– still have blood sugar issues?
The second source of fuel for the mitochondria -– glucose –- has an equally important role in the function of cells.
With the epidemic of diabetes and metabolic syndrome plaguing the industrial world in recent years, blood sugar and insulin have gotten their fair share of media attention.
In fact, blood sugar balance is a major tenet of virtually every diet book from The Zone to The Atkins Diet. These are health-conscious, educated individuals who do not spend their time eating Twinkies, bingeing at McDonalds and competing in the World’s Laziest Couch Potato competition.
Rather, we see people who eat well, exercise regularly, have normal body composition and take supplements, but still don’t feel well. Insulin resistance, which is characterized by two things: chronically elevated blood sugar levels, and subsequent elevated insulin levels to help deal with the blood sugar. And while each of these have their separate issues metabolically, both will cause issues with the function of mitochondria because there is not a steady stream of blood sugar available for ATP (energy) production. When someone is insulin resistant, glucose cannot effectively enter into the cell –- chronically elevated insulin levels create dysfunctional insulin receptor sites on the cell. Because blood sugar is not adequately entering the cells, it stays in general circulation rather than being stored.
Characteristic symptoms of insulin resistance include: fatigue after meals, craving for sweets that doesn’t go away when sweets are eaten, increased thirst, and frequent urination. Individuals with this pattern and periods of low blood sugar will have surges of insulin, rather than chronically elevated levels. Normally, the body should respond to low blood sugar by producing cortisol to increase blood sugar levels. Symptoms are usually relieved after eating because meals provide a source of glucose that their body could not create itself. Because their bodies rely on adrenaline to elevate blood sugar, people with some degree of hypoglycemia can have insulin surges between meals, rather than following meals, or chronically, as in insulin resistance. But here is one of the biggest points: looking healthy, having a muscular body, and exercising regularly does not mean that you have normal blood sugar management.
Though there are a number of mechanisms involved in this cycle, here is a basic explanation. In other words, you could have a perfect diet and exercise program, but if you have elevated cortisol levels, you may also be increasing your blood sugar from the inside. Two hours after a meal, it will ideally be between 85 and 100 depending on the size and quality of the meal. You could eat a meal, and then track your blood sugar at 30 minute intervals for 2 hours following a meal.
A good protein-based meal with adequate levels of healthy fat and fibre should not raise your blood sugar levels too high. For most of you, the first step toward eating properly for blood sugar management is starting with the Precision Nutrition System.   Indeed, over 85% of our clients see the types of results they’re looking for by following this program. However, for the other 15% that use the program and still need to go a bit deeper, working with a coach through Precision Nutrition Coaching is the next step.
Blood sugar dysregulation and elevated insulin levels have negative impacts on numerous physiological systems in the body. But on a fundamental level if adequate glucose cannot enter a cell, the mitochondria will not be able to produce optimal amounts of ATP to run the cells, organs and systems of the body, and we will not be optimally healthy, much less have the body we desire.
The mitochondria use two primary sources of fuel to produce the energy required to run your body effectively: oxygen and glucose. These are basic fundamentals to health and fitness that must be addressed before deciding which supplement works better or whose workout program is the best for fat loss. In it you’ll learn the best eating, exercise, and lifestyle strategies — unique and personal — for you.

How predisposed am I to insulin resistance?  One look at a picture of me in my non-lean state, coupled with an understanding of my family history, and it’s clear I didn’t hit the genetic lottery with respect to insulin resistance.  Hence, I am towards the right of graph.
As you can see, based on my poor genes and lofty goals, I find myself in the upper right square, which means I need to adopt the greatest amount of carbohydrate restriction. Finally, note that under no circumstance do I ever count calories (for the sake of limiting them).  When I was first transitioning into ketosis I did need to count how much carbohydrate and protein I was consuming – anything over about 50 grams of carbs and 150 grams of protein makes it difficult to generate sufficient ketones – but I do not ever count calories for the sake of restricting them. One last point on supplements – I do not take a multivitamin at this time, but I am looking into it a bit more closely.   My concern is that 1) they may not be necessary when you remove glucose from your diet (I’ll write about why in the future), and 2) they may actually do direct harm, as a result of contaminants. Breakfast: Scrambled eggs (6 yolks, 3 whites**, with added heavy fat cream) cooked in coconut oil, 3 or 4 sausage patties (be sure to look for brands not cured in sugar). I go to great lengths to avoid sugar which, unfortunately, shows up in virtually every highly processed food. I consume only modest amounts of fruit (one serving per day, at most, and only in the form of berries, which contain the least amount of fructose). I go out of my way to eat as much fat as possible, especially monounsaturated and saturated fat (the only fat I avoid is omega-6 polyunsaturated fat). I have a few “go to” meals that I eat several times per week.  I do this because I really like them and it’s quick and easy make them. I am going primal (Sisson) have eliminated almost all sugars and carbs and increasing saturated fats (coconut oil, organic whole whipping cream in my omelets, ghee, grass fed steaks when I can etc.).
I have to say these panic attacks for lack of a better word are mildly terrifying (if there can be such a thing!) and seemed to coincide with my attempts to go to a diet that eventually supports nutritional ketosis. Any thoughts you have on this or if you did write about your experience and can direct me there – I would be grateful for either.


I think there are 2 distinct mechanisms for the cravings: the lack of metabolic flexibility, and the dominion of the wrong gut flora.
While the first is relatively easy to resolve with a little education, trial-and-error, and persistence (you just go low carb, don’t ever cheat, and things do get better), the second is not so simple.
The second type, however, is much more subtle: you go for the chocolate cupboard without actually knowing why.
It is known that gut bacteria produce neurotransmitters that can hijack the vagus nerve; of course this can only happen if they are living inside your small intestine, because the large intestine (where the gut bacteria should be in very small numbers) is not graced with that nerve. Starving the pathogenic flora with intermittent fasting is another good technique that helped me a lot. Scott, the lands we use to raise grains takes up a lot of space that must be denuded of their natural ecosystems and then demand chemical fertilisers for their success.
The whole story of plant vs animal ingestion is complex and far beyond the realm or reason of proponents on either side. And if humans are naturally carnivores (or omnivores) for perfect health, should we be deprived of our needs?
In reply to Scott C Irwin – probably no longer relevant to you since your post is over a year old.
I was under the impression that the brain, bone marrow, and liver can oxidize carbs only for the production of ATP?
You write “It turned out – and I will write about this in great detail later on – I was making a few critical errors in my application.
I just wanted to thank you for making the two much needed items clear (fat and sodium) in your post above. And do you still suggest slowly reducing carbs over a period of months, or do you now recommend just diving in (no swimming-related pun intended!)?

Are anemia and low oxygen delivery to blame?) I focused on oxygen, one of the two fuel sources for what is arguably one of the most important components of your cell, the mitochondria. And with good reason: imbalanced blood sugar levels are at the crux of many health issues, including being overweight. As a result, the body must produce higher levels of insulin to remove glucose from the blood stream, which causes even greater metabolic dysfunction. People with hypoglycemia can experience symptoms such as lightheadedness, irritability, shakiness and fatigue between meals, which is often relieved after eating. However, in this case, periodically hypoglycemic people usually have low adrenal function and rely on adrenaline to elevate blood sugar between meals, which causes the shakiness and and lightheadedness between meals. In fact, researchers have started using new terms like “non-obese insulin resistance” and “atypical metabolic syndrome” because normal-looking people are having blood sugar management issues. A good blood chemistry screen will contain enough markers to adequately identify patterns of blood sugar mismanagement. They usually cost around $50 and give you the ability to look at your blood sugar throughout the day.
If it does, either the macronutrient ratio was off, the meal was too large, or in some cases, you might have a sensitivity to the food that causes a stress response and elevates blood sugar. Clinically, these are “high priority” situations because if either one of these processes are not working correctly, nothing will. Identify your HbA1c test score, mean blood and glucose level to know if your blood glucose is in the optimum level. Good science, bad interpretationGravity and insulin: the dynamic duoIf low carb eating is so effective, why are people still overweight?
I have a lot of diabetes in my family, in fact my sister died at the age of 15 due to ketoacidosis.
Have you thought about the ecological impacts of this dietary shift and what they might be if large numbers of people took this up? Low carb allows you to recover the liver, pancreas, adipocytes, mitochondria, etc, and this takes a few weeks to kick in and stabilize completely. Feed animals need lesser lands, scrub lands that they brows from and help enrich naturally- think bison (buffalo) on the prairies.
Our ancient brethren with population success ran through the wild species in their lands, and agriculture had to come about for their survival.
Logic taken to extreme would then suggest we also condemn wild carnivores for their behaviour.
So how would you modify it if you were recommending dietary changes for athletes who require “sprint speed” as well as high levels of muscular strength? Thank you so much for documenting your experiences and taking the time to answer questions! Make sure your slippers are in a handy location too, so you’ll remember to wear them inside to avoid injury.This is just one of many simple, quick tips that can be done in minutes to better manage your diabetes and help prevent complications. It is intended for general information purposes only and does not address individual circumstances.
Without oxygen, it is impossible for your cells to work at their full capacity or for you to be healthy. Excess sugar or carbohydrates, excessively large meals or glycemically imbalanced meals can excessively elevate blood sugar levels, causing this cycle to begin. For example, if you eat celery and almond butter, or a salad with grilled chicken, your blood sugar should not go above 120 at any point after the meal. His clinical interests are nutrition, lipidology, endocrinology, and a few other cool things.


Do you exercise multiple hours a day… or does the [calories in (food)] – [calories out (basal metabolism + exercise)] model of weight gain not apply when you consume mostly fats? To nuance that a bit, leaving aside an animal rights rationale, there are persuasive arguments that producing and consuming animal-based foods is energy and resource inefficient, in comparison with vegetable-based foods, even when it’s produced locally through organic methods.
In the meantime you will suffer from hiperinsulinism which will prompt hypoglycemia attacks. This happened to me (and still happens once in a while) long after the metabolic problems were resolved. The amount of calories one needs from animals may be less than is consumed from todays diet dependent upon plants; unless like Dr Peter one is into extreme fitness- most people are not.
He has written specifically about Leptin's role (along with insulin) in determining if you brain will allow your body to burn fat or not.
Do a quick body scanAs you dry off from your shower each day, inspect your body from head to toe. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health.
Over time, I’ll share it here and there, but what I eat is not at all the focus of this blog. Would adapting this approach so that nutritional ketosis is used to achieve the basic goals of reducing indicators for metabolic syndrome, and a modified version (still high fat, low carb, low protein) used for long-term maintenance? Some of your fats are coming from plant-based oils and other plant-based foods, but it looks like the majority still comes from meat, dairy, and eggs. I had lost all the extra weight, cleansed my liver, and stopped having any hint of hypos long ago, and would still be startled by that sudden need for chocolate after a meal. But you’ll be strengthening the good kind of flora and in the process restoring you small and large intestine mucosa.
Properly managed, they could have continued to be a healthy source of food for humans.) I would speculate that in a perfect world properly managed lands could allow for animal eating without stress to the lands (and less stress to the animals than what we perpetrate on them today).
For some reason I am fine with coconut milk contained within foods but not virgin coconut oil. While recommending a LCHF diet, he distinguishes between fat types and limits beef, cheese and heavy cream to 1-2 servings per week. Never ignore professional medical advice in seeking treatment because of something you have read on the BootsWebMD Site.
My question is, since I do not have diabetes and am trying to prevent diabetes, will entering into ketosis help or harm me?
I’m all for optimizing individual health, but want to do that in a socially and ecologically responsible way.
I am wondering if this is the low-carb flu I have read about, or I am doing something wrong to which you allude in your own experience above. I'd love your thoughts on both of these topics as your blog posts and diet show you have a differing opinion.
I have read so much in the last 3 months that leads me to believe that for optimum health and longevity I should stay on this plan, but in order to do so I need to fix whatever is preventing me from feeling more energetic and clearer-headed as many people eating this way describe.
I have to admit that after even after all I've researched I still have that little voice that warns me about so much saturated fat and I find corroboration even in the LCHF world. I am also been dabbling in IF(intermittent fasting) to help achieve higher ketosis but read somewhere that it could be harmful for women to fast. Prepare emergency snack packsPut a few glucose tablets and sweets (for example jelly babies) into bags.
I currently measure my ketones with a keto-stix, what are some standards that i would have to meet to say that I am in a state of”nutritional ketosis”?? Skipping a meal, taking too much diabetes medication and exercising harder than usual without eating can trigger it. Take a 2-minute testPut your glucose monitor on your bedside table to remind you to check blood sugar first thing in the morning and before bedtime, if your doctor advises. Checking before and after exercise can help you learn how it affects your levels and it may help you avoid dangerous drops in blood sugar levels.  Make insulin work for your lifestyleIf your days are fast-paced and meal times are unpredictable, ask your doctor about rapid-acting or fast-acting insulin.
These rapidly acting insulins can be taken just before eating and have an effect on your blood sugars within 30 minutes.
Diabetes UK has plenty of low glycaemic index suggestions, meaning they aren't likely to cause spikes in blood sugar. Put a list on your fridge so it's at the ready when you make your shopping list, plan meals or look in the fridge for something to eat.
Drink plenty of water and other non-alcoholic fluids to help your skin stay hydrated and healthy. Remember your medical alert braceletPut your medical alert bracelet or pendant near your watch, rings or other jewellery you wear every day. In an emergency where you’re confused or unable to speak, it can save critical time by letting others know about your diabetes.
Exercise in spurtsExercising 30 minutes a day is an important part of managing your diabetes, but it can be difficult to fit into a busy lifestyle. Assemble a first-aid kitDiabetes complications can turn a minor injury into a major problem.
