Low Carb Diets High BAC

Diet food on forkMany people engage in low carb, high proteins diets as a way to lose weight. However, many people on these types of diets do not realize that a low carb diet can lead to physical and physiological symptoms that often mimic those of being under the influence of alcohol. In some cases, a low carb diet can lead to elevated BAC readings on a breath testing device. This can result in drivers on low carb diets being arrested for and even charged with driving under the influence offenses.

Low Carb Diets Can Mislead BAC

Similar to drivers who suffer from diabetes, those who consume few or no carbohydrates as part of their diet will force their body to break down fats and other stored proteins for energy. When fats are broken down, the liver will produce ketones as a byproduct. Ketones have a molecular composition that is highly similar to that of isopropyl alcohol which can be confused as ethyl alcohol (alcohol that is consumed) by many breath testing devices. Ketones are produced in the liver and then excreted in the urine and breath. In addition to low carb diets, conditions such as diabetes, hypoglycemia and fasting can lead to increased ketone production which can subsequently cause DUI symptoms and can mislead breath testing devices.

When a person is producing a high level of ketones, a condition also known as “ketosis,” he or she may exhibit symptoms such as dehydration, poor coordination, a breath “sweetness” that can be mistaken for alcohol, sluggishness and a flushed face. These symptoms are also commonly associated with alcohol and drug intoxication. As a result, an officer who stops a driver may suspect that the driver has been drinking based on the presence of the symptoms listed above. However, these symptoms may be caused by ketosis and not alcohol consumption.

The driver may be asked to perform a series of field sobriety tests that are designed to measure driver coordination and balance. A driver who is suffering from ketosis or who is on a low carb diet may have difficulty successfully completing these tests which may lead the investigating officer to believe that the driver is under the influence. The driver may stumble during the walk and turn test or may have difficulty balancing during the one-leg stand test. The officer administering the test may interpret these actions as evidence that the driver is under the influence of alcohol, when in fact he or she is experience the side effects of a low carb diet.

In addition to low carb diets, ketosis can also occur in drivers who are anorexic or are fasting, those who have experienced excessive vomiting or diarrhea and have lost nutrients and other drivers who are not eating enough nutrients. Ketosis is also observed in those who engage in prolonged exercise as well as people on high-fat diets.

Excess Ketones Can Elevate BAC Readings

The excess ketones can also lead to elevated BAC readings on breath testing devices, as the ketones can be mistaken for alcohol on these machines. It may be necessary to obtain an expert witness who can explain the physiological effects of a low-carb diet as well as an expert who can discuss the molecular composition of ketones and their ability to “trick” breath testing devices.

Michael Kraut is outstanding! He genuinely cared about my case and instructed my mom and I throughout the entire process. He was very clear on what he needed in order to receive the best results. He kept us updated until the end. I thank him so much for getting my charges rejected. I highly recommend him to anyone with legal needs! Shaquan
I contacted Michael with concern for my personal and business reputation. He was very reassuring and confident the entire time. After about 3 weeks it was determined that no charges were being filed by any agency and I was in the clear of any investigation. One thing that is amazing is just how FAST Michael is at replying to phone calls, texts, and even emails! We are talking under 30 minutes in most cases. That is unheard of for most attorneys! Michael is incredible and not your typical run of the mill attorney. For best results hire him if you feel like you might be under investigation or could face charges. Even if you know you are innocent it is best to take care of the smoke before it becomes a fire. Brad
Michael Kraut is-hands down-the best criminal defense attorney and I can't begin to thank him for all that he did for me and my family. I reached out to him in the middle of the night and less than a couple hours later, he had gotten back to me and scheduled a meeting. He's a no-nonsense attorney who knows how to get the job done! From the second we retained him, I had peace of mind in knowing that we were in the best hands possible. If Michael Kraut couldn't get it done, I knew that it couldn't be done at all. You can't put a price tag on your freedom. He was worth every single penny. Lida
Michael Kraut is an outstanding attorney. He was extremely professional, and straightforward, yet sensitive with my case. I am confident I made the right choice by hiring Michael. I highly recommend him to anyone seeking a truly experienced lawyer. Daniel
Michael Kraut - I cannot thank you enough for all that you did for ​my son. When I came to you I read that you used to be a district attorney but I never knew how much that meant until I watch you in court. I knew it took 3 months but the final day when I heard the judge say that all charges were dismissed it was all worth it! I will always be grateful for all that you did for us. A.N.
