It does not work for anybody except those with glucose metabolism deficiency, usually exhibited by seizures. There is no 'little bit glucose metabolism deficiency.'

The only way to tell if it will help you is to do it totally for at least 7 days. It can take 7 days for the body to exhaust stored glycogen and trigger ketosis. You will develop an acetone like breath. Keto-acidosis is a risk.

But, I can all but guarantee you that it will not help. Otherwise, you would be manifesting serious symptoms, seizure, motor control, psychosis, etc.
