I wrote this post at about the same time Germany won the World Cup in Rio de Janeiro in 2014. There’s been a lot of moving and shaking in the world of exogenous ketones since then, not to mention soccer. Looking back on my post, I still consider it relevant in terms of what exogenous ketones possibly can (and cannot) do for performance. In this case, to see if exogenous ketone esters provide me a “boost” by allowing me to do the same amount of work while expending less energy (and work at a relatively lower VO2) compared to no supplementation.
I’m just getting back into an active lifestyle after being sedentary for a few years.. Rough start I must admit but I’m focused.. Objective is to lose 80lbs. I’ve previously had my body in ketosis when I was dieting and working out so I can attest to the benefits I’ve felt before.. Now that I see Exogenous Ketones are available, I’m wondering if it’s recommended to start taking them to help jumpstart my body into ketosis since that is the goal for burning fat…

Personally, I do this on Friday night to Saturday night, so if something happens and my hunger hasn't crashed by Sunday morning, I have another day that I can go zero carb to keep the momentum going. While the body will trigger ketosis as soon as you run out of glycogen, hunger is attached to your triglyceride and insulin levels, which might take an extra day to normalize.
If you truly want to optimize health and performance, magnesium should not be neglected. There is still more research to be done on its potential. Good sources of magnesium include whole grains, nuts, seeds, legumes, green leafy vegetables, and supplements. However, be careful about taking too much magnesium at one time, or else you might end up running to the bathroom in a hurry.
Venous blood samples (2 ml) were obtained during all visits using a 22 G catheter inserted percutaneously into an antecubital vein. The catheter was kept patent using a saline flush following each sample collection. Additionally, during Study 1, arterialized blood from a catheter inserted into a heated hand (Forster et al., 1972) was collected into heparinized blood gas syringes (PICO 100, Radiometer, Copenhagen) from a subset of participants (n = 7) and immediately analyzed for pH and electrolytes using a clinical blood gas analyser (ABL, Radiometer, Copenhagen).
Price: The supplements are expensive – very expensive. At the top end, if you follow Prüvit’s guidelines on “getting in the n8tive zone” (which is such a gimmicky marketing slogan it almost makes me cringe), you will require 2 servings of their Keto-OS product per day. This means around 60 servings per month, which will set you back a whopping $390 per month if you buy direct from their website! In the case of Prüvit, this is in part due to the multi-level marketing structure they operate under.
Consuming exogenous ketones isn't the same as following a ketogenic diet–the ketones in the blood haven't been naturally produced by the breakdown of fat stores. However, scientists believe many of the health benefits of the keto diet and fasting (aside from weight loss) are triggered by ketones. Therefore, raising ketone levels through either endogenous or exogenous ketosis could help to improve health and performance by:
It's a common misconception among those who are trying to lose weight that fat is dangerous, but this is not the case at all. You will need to rely on healthy sources of fat to reach ketosis, and this can be achieved by choosing the right type of food. Go with those that contain butter, olive oil, coconut oil and avocado oil, among others. Opt for oils that are not heavily processed so you can get the most benefits out of them.
Supplemental BHB’s are ideal for people new to the ketogenic way of eating. The changes that happen in your brain and body when adapting to a VLC diet are both immediate and profound. For example, our kidney’s start processing minerals salts much more efficiently. Ironically, after years of being advised to decrease our intake of salt (sodium), it turns out that for people transitioning away from the Standard American Diet (SAD diet) towards a lower carb or ketogenic diet there is actually a need to increase dietary mineral salts such as potassium, sodium, magnesium and calcium. During the process of becoming keto-adapted, it is very important to increase your intake of these essential minerals, in order to prevent the onset of unpleasant symptoms (known as “keto flu”).
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...
If Prüvit’s Keto OS-Max is “not a weight loss supplement” as stated in their disclaimer, why is the official website full of success stories of people who claim to have lost huge amounts of weight from taking the supplements? Ketōnd also feature a number of weight loss success stories on their site. I will get to why there is a problem with weight loss claims later on.
I also concluded that post by discussing the possibility of testing this (theoretical) idea in a real person, with the help of exogenous (i.e., synthetic) ketones. I have seen this effect in (unpublished) data in world class athletes not on a ketogenic diet who have supplemented with exogenous ketones (more on that, below). Case after case showed a small, but significant increase in sub-threshold performance (as an example, efforts longer than about 4 minutes all-out).
