Could a fat-loss diet explain a failed breath test?

On Behalf of | Jun 4, 2026 | Drunk Driving Defense

Drunk driving charges often follow poor vehicle operation. Those who swerve all over or hit the brakes without reason may end up stopped by police officers. Driving under the influence (DUI) arrests also frequently follow collisions, as people who lose control and cause crashes are typically liable for the consequences of their choices.

In some cases, a traffic stop that began for a different reason may culminate in a DUI arrest because a driver fails a breath test. For those on specialty fat-loss diets, the risk of a false positive on a breath test is higher than they might realize.

How diet affects body chemistry

The keto diet has been popular in recent years due to its ability to help people burn stubborn fat. People intentionally push their bodies into a state of ketoacidosis by controlling the macronutrients they ingest.

Ketoacidosis prompts the body to burn fat. The byproducts of fat burning include water and also acetone. The body gets rid of those byproducts through the breath. People exhale acetone and other chemical byproducts during fat loss.

For most people, that is not a problematic bodily function. For those subject to a breath test, acetone can cause a false positive or can drastically increase the blood alcohol concentration (BAC) calculated by a chemical testing device.

If people on a specialized fat-burning diet fail a chemical test and cannot understand why, their diet could be part of the explanation. Reviewing medical records with a skilled legal team could help those concerned about a failed breath test plan a DUI defense strategy. An alternate explanation for a failed test can reduce the likelihood of a criminal conviction.
