Based on the available information, it is not possible to definitively state that an alcohol-free diet guarantees complete liver recovery. The liver has a remarkable capacity to repair itself when it is not exposed to harmful substances, such as alcohol [1]. Abstaining from alcohol is generally considered the most effective way to allow the liver to recover from alcohol-related damage [2]. However, the extent of recovery can vary greatly depending on the individual and the severity of the liver damage [1].

In some cases, even with prolonged abstinence from alcohol, the liver may not be able to fully recover, leading to conditions such as cirrhosis or liver failure [1]. Factors such as the duration and amount of alcohol consumption, age, sex, and the presence of other health conditions can all impact the liver's ability to recover [1].

It is important to note that while an alcohol-free diet is a crucial step in liver recovery, it may not be the only necessary step. In some cases, medical treatment or lifestyle changes may also be required [1]. Therefore, it is always recommended to consult with a healthcare professional for personalized advice on liver health and recovery [2].

In conclusion, while abstaining from alcohol can facilitate liver recovery, it does not guarantee complete recovery. The extent of recovery depends on various factors and should be evaluated and monitored by a healthcare professional.
