Try your best to eat 3-4 course meals. Certain foods such as teff, chicken sausage, coconut milk, coconut oil, pumpkin, etc. are very good for weight gain. Have you tried the forum’s bread recipes? These can aid in weight gain as well.
I personally lost a lot of weight initially on the diet; I went from 155 pounds to 135, and now I probably weigh close to 160 pounds. Your body uses a lot of resources to fight candida…and as it becomes less taxing, you will have more energy to store away for later.
