Most of your diet is not going to starve the candida, the reason you haven’t experienced success with the diet is because it isn’t strict enough.
You’re eating things like rye bread, grapefruit, porridge, rice milk, rice puffs, rice cakes, brown rice which all feed candida. I haven’t had any of those items throughout most of my treatment, and I’ve been on the diet for a year!
I also don’t understand why you’ve stopped taking probiotics and antifungals.
One thing you could try for your acne is to go on an anti-inflammatory diet with items such as salmon, blueberries, broccoli, etc. This might help some.
A second thing you should try is to sweat out the toxins via the skin by doing a hot tube, jacuzzi, steam room, sauna, or even a hot bath; this will likely help with the skin better than anything else you are doing.
