Yes yeast can effect men as well. Read through the yeast forum on this site to see if you have the symptoms. Seeing a doctor would be up to you. Following the candidia restricted diet, taking probiotics, and some of the other things would probably allow you to take care of it on your own though.

As for the 20g carbs, some people actully lose better on 30g or 40g a day instead of 20. If cutting carbs more doesn't help, you might try moving on to OWL and even raising them a bit.
