I’ve been a voice actor since 2004 and I’ve been on a low carbohydrate, high fat diet (LCHF) since April 10th, 2017. Over the past 9 months I’ve lost 86 lbs (down from 270 lbs to 184 lbs). I’d like to tell you about my experience regarding my vocal performance and health while on this type of diet.

I have received several requests, informally on reddit and formally from some of my clients, to write about anything I’ve noticed with my voice due to being on a high fat diet. I was extremely curious to see if there had been any changes at all with my voice, so I figured it was worth a little investigation.

I can only provide you with anecdotal evidence and my own experiences, so going into the details about the modified ketogenic diet I was using is beyond the scope of this analysis. (I’m not a doctor nor a nutritionist and I highly suggest you seek out a doctor should you have any questions about this type of diet). A great place to start is the /r/keto sidebar.
