The interplay of exercise and ketosis – Part II - You’ll recall from last week’s post I did a self- experiment to see if I could learn something about the interplay of exercise and ketosis, at least in myself. To understand this discussion, you’ll want to have read Part I of this post. However, before getting to this, I want to digress and briefly address two unrelated issues: Some of you (about 6. Harvard’s School of Public Health. Here is the summary of the results from my personal experiment: Let’s take a closer look at what may have been going on in each workout and see what we can learn. Swimming. This workout probably produced the most lactate of the three workouts (we don’t know for sure because I only measured immediate pre- and post- levels without measuring in- workout levels). In reality, cardiac myocytes (heart muscle cells) also “like” B- OHB more than glucose and probably also access it when it is abundant. Lactate levels by the end of the ride were effectively unchanged though. Based on “feel,” I suspect I hit peak lactate levels of 8 to 1. M on this ride during peak efforts, but I had ample time to clear it. A few observations: I consumed 6. Generation UCAN’s super starch), yet this did not appear to negatively impact my ability to generate ketones. I’ll write a lot about these later, but for now just know the CP system is good for very short bursts of energy (say 1. The Fourth Amendment's barriers to unreasonable searches and seizures don't get the attention the First Amendment does, but they're at least as important as a. You’ll recall from last week’s post I did a self-experiment to see if I could learn something about the interplay of exercise and ketosis, at least in myself. Original Article. Exercise Capacity and Mortality among Men Referred for Exercise Testing. Jonathan Myers, Ph.D., Manish Prakash, M.D., Victor Froelicher, M.D., Dat. I do not believe either accounted for the sharp rise in blood glucose and, again, I believe hepatic glucose output in response to a strong catecholamine surge attributed to this increase. Lactate levels also rose, though probably less so than during a peak swim effort. But I have a very hard time believing 3 or 4 gm of BCAA could suppress B- OHB. When you see hoof prints in the sand, you should probably think of horses before you think of zebras. Conversely, there is some evidence that lactate promotes re- esterification of fatty acids into triglycerides within adipose cells. High levels of lactate take free fatty acids and help promote putting them back into storage form. In other words, we may be missing this effect because of my sampling error – I only sampled twice per workout, rather than multiple times throughout the workout. I think it’s safe to say I did not definitively answer any questions, which is not surprising given the number of confounding factors, lack of controls, and sample size of one. Take the following example: Someone my size can probably store about 1. Disclaimer: I am not a doctor. I don’t even play one on TV. Below you will read about my experience with Hashimoto’s Thyroiditis as a vegan, advice my doctors. A few years back, I wrote an article explaining 17 possible reasons why you’re not losing weight. It was a troubleshooting guide of sorts, aimed at helping people. This represents about 1. I can store at any one time. Before I was ketotic, you’ll recall from my post on the change in my physical performance, my RQ at 6. VO2 (about 2,5. 00 m. L of O2 per min consumption) was nearly 1. I can hold for hours from a cardiovascular fitness standpoint) I required 9. ![]() Now I only store 5. In ketosis, my RQ at 6. VO2 is 0. 7. 7 (at last check), telling me I am getting only 2. Nearly 5 hours. Just consume more glucose as you ride! ![]() It’s not that simple, but you’ll have to wait until my upcoming post, “What does exercise have to do with being in the ICU” to find out. Going back to the black sheep example I open Part I of this post with, we know that at least one person in nutritional ketosis seems to make enough liver and muscle glycogen to support even the most demanding of his energetic needs. As the ketogenic diet gains popularity, it’s important to have a balanced discussion regarding the merits of this diet. Let me emphasize right out of the gate that. Truth be told, I really dislike labels, especially when it comes to diet. I don’t like being pigeonholed into one specific category, and having to follow the.
