Yes I have tried it and still do it to this day. I do the "12 pm - 8pm" version. Helped me a lot. Turned me from chubby, thick Abdi to semi buff, flat Abdi in a span of 1-2 month's. Most people could bearly recognize me. Also speeded up my growth by a lot and made my voice deeper. Apperanly, fasting increases a male's tesastorone by over 1000%.
The only thing it probably did was making your hair harder
