The amount of alcohol in your body is tested through a test known as the BAC (blood alcohol content) and is used to determine sobriety. Different people process alcohol at different rates and some of the factors that go into the assessment of your BAC content are your individual genetics, your sex (female process at slower rates than men), your size and weight, the type of alcohol that you consume, and how much food you have consumed recently.
The quantity of food in your body will reduce the absorption rate of alcohol and will slow down the speed at which you process the alcohol. When you begin drinking on an empty stomach, you will typically begin to process the alcohol after 15 minutes of consuming it. With food in your stomach, the process is delayed to 30 minutes. Further, the rate in which your body finishes processing it will also be delayed stretching from 2.5 hours to 3 hours of time. However, with food in your stomach, your BAC will reach a lower peak and will be processed out of your body faster from that height, which will typically help to protect you when you are being tested for sobriety.
