## Customer Reviews

### ⭐⭐⭐⭐⭐ True Science
*by T***Y on May 3, 2025*

True science discussed. Amazing the misquotes that are in the nutritional literature when people bash keto and low carb diets.

### ⭐⭐⭐⭐⭐ Mind blowing information!
*by J***E on August 4, 2013*

Well written, highly credentialed and experienced in subject matter authors, well documented, and thorough coverage of the topic. They basically make the case that high carb diets and carbo-loading for endurance athletes is outdated. And they make the case that the exact opposite is what yields the best results: high fat, low carb. One reason that high carb might still be so prevalent is that it takes 2-3 weeks for your body to adapt to a low carb, high fat diet. Results don't come until after you are fully "keto-adapted." Most athletes are apparently not patient enough to go through this frustrating adaptation process.Ketones are the breakdown products of fats that your brain can burn for energy. But, if lots of sugar from carbs are present in the blood, then the brain will not burn ketones, only sugar. It takes two weeks of consistently maintained target blood levels of ketones in order for the brain to produce enough ketone pumps to allow enough into the brain cells for normal energy production. The main inhibiting factor for high blood ketone levels is insulin. The only way to keep insulin levels low enough to allow ketones to rise high enough is to stay away from high amounts of dietary sugars and carbs.Along with low insulin levels comes the transition allowing muscles to burn fatty acids instead of glucose. Since body stores of glucose are at best 2 hours worth of energy, and fat stores are essentially unlimited, we see that muscles trained to burn fat instead of glucose as their primary fuel is optimal for endurance sports. And, not only will your muscles never run out of fuel (even if you don't refuel during your race), but neither will your brain. In fact, the worst part about "hitting the wall" due to low glycoge/glucose stores during a race is mental confusion due to low blood glucose.In a study of several non-athletes who were keto-adapted, researchers injected insulin into the subjects until blood glucose levels fell below 30 (normal is 70-120). At this low level, not only did the subjects not fall into a coma, but they didn't have any symptoms of low blood sugar! This is because their brains were burning fat (ketones) for energy, not sugar, making the low glucose levels irrelevant to proper brain function!Obviously, there are non-athletic implications for a low carb diet: natural diabetes control, weight loss (targeting fat loss), and preventing symptoms of low blood sugar (hypoglycemia). It turns out that about 70% of people with seizures are cured by a keto-genic low carb diet.The coolest part of the book is biofeedback available with an inexpensive "ketone" testing machine similar to a diabetic blood sugar testing machine that allows you to know in black and white whether your diet and exercise routine is working or not. If you aren't getting the results you were promised, but your blood levels of ketones are too low, then you know it's because you are doing something wrong. You can test your blood after eating certain foods to get immediate feedback on that food's impact on your body as far as ketones (and thus indirectly insulin) are concerned.The nova max ketone tester is the one I use because its test strips are about half the cost of the other brand. You can find and purchase these on amazon as well.Now that I am keto-adapted for a few weeks now, I have noticed a few differences in my running workouts. 1) My energy is much more stable throughout the workout, 2) I seem to get less dehydrated during workouts (this is likely due to the fact that burning fat uses less water than does burning sugar), 3) I don't seem to have to breath as hard (this might be due to the fact that burning fat gives off 25% less CO2 than burning sugar), and 4) The runners high is less obvious at the end of my workout (upon reflection, I think that this is because I seem to have a low level of runners high all the time now, not just after running).One downside is that I seem to be thirstier between workouts. In the book they say that when ketoadapted, the body shifts from conserving sodium and peeing out potassium, to conserving potassium and peeing out sodium. This may explain why I am thirstier since if I am peeing out my salt, I can't retain as much water, thus am more dehydrated easier. It is interesting that even though I feel more dehydrated between workouts, my mouth is much more moist during workouts. Maybe this is because I'm not breathing as hard during the workout?

### ⭐⭐⭐⭐ Interesting read, but still left with questions
*by M***. on August 12, 2019*

I recently completed a 545mile bike ride over 7 days and gained over 10lbs (not all muscle), and it was after that that I realized I needed to make some serious dietary changes. I started working with a nutritionist, and have started a version of low carb, but never with the expectation of cutting carbs out. I wasn’t sure how to fuel on rides anymore when I was eating mostly vegetables and protein. My nutritionist recommended this book as a starting point.I found this to be a difficult, but interesting read. Like the authors said, it did become acronym soup after a couple chapters, which made for difficulty in understanding the science. I found I kept flipping to the glossary, and then back to where the term was first introduced to remind myself of what it was. I’m still not sure I grasped all of the science, but I believe I have the main points.I’m intrigued by the concepts, but not sure it fully gave me the tools I need to actually make the shift to low carb. For one, most of their recommended food substitutes included a lot of dairy, which I cannot eat, so there I would need more guidance. It also didn’t answer the basics questions I had about, how an athlete would fuel when on a long bike ride or run. The book simply mentions you can go longer without bonking, etc. There were some product recommendations that I will be looking into more.Overall, there’s not a lot of info out there, so I would recommend this book as a good, science backed, place to start.
