Would you recommend periods of complete fasting (3-5 days)?

I do not recommend fasting without supervision.

Side Effects to watch for if fasting:

These include headaches, dizziness, lightheadedness, fatigue, low blood pressure and abnormal heart rhythms. People who are fasting may experience an impaired ability to conduct certain tasks, such as operate machinery or drive a vehicle.

If you must fast I suggest you fast only one day the first time. Then if it goes well, gradually increase at intervals of two weeks. If you do well then increase your experiment as outlined below.

Start

Two weeks – two days fast

Two weeks – three days fast

Two weeks – four days fast

And continue as you see fit.
