As someone who has been unable to eat for a week or more at a time due to gastrointestinal issues (from Lyme), take from me that fasting will not kill Lyme. What it does do is reduce your reserve strength, decrease your metabolism, and can lead to a host of other issues.
Theraputic fasting is usually done for a few days, but usually includes plenty of fluids, such as apple juice fasting. My Mom does this once a year to detox - she's found that she doesn't get pneumonia or bronchitis as easily when she fasts once a year.
