I'm a 6'0" male and fluctuate between 158 and 165 pounds depending on my diet.  however, when fasting, I drop weight substantially - especially after the first three days.  For many this may be a silver lining, but it concerns me because it feels like I'm moving away from my ideal weight.  Is there anything I can take during a fast to help maintain my bodyweight?  I read that olive oil would help, but I'm concerned this may also slow down the healing process.  Thanks, any thoughts/discussion would be much appreciated!

Mike I have to say I have been in your boat. I am 5'10 and 160 normally but through my first two fasts about a month apart I dropped like a rock down to 148. People were asking me what was wrong I got skinny. Doing some experimenting food sensitivity wise I found an ice cream with just 4 ingredients (milk, sugar, eggs, and cream). I had tested eggs and milk and been ok so I ate a lot of that over the next month but only on a rotation basis ie I would eat a lot for a couple of days then wait 4 days before eating it again. In a months time I gained back all 12 lbs. That was a couple of months ago now I am about 162. Also I found alcohol was one of about 10 things that are triggers for me. I quit drinking and my gut seems to be healing now slowly. When I do get a bad food my symptoms don't last as long as before. I am much much improved but it took me 9 months of constant recording what I ate, fasting, and experimenting to get to this point. I am not healed but I am close now!
