Need some advice on my water fast day 8 and quite thin.

I am on day 8 of my water fast. I am 5'10.5" tall. I started the fast weighing 145, I am now 132. I also have a small frame but a decent amount of muscle. I don't have much fat on my body.

I am looking to do 21 days, is this out of reach form me being so thin already? I am worried that I won't have enough fat reserves to take me to 21 days.

Any help is much appreciated. Tweet
