I had loss of appetite before the treatment and much more when I started it. It could have been a die-off, but I was also recently diagnosed with hiatus hernia and erosion caused by acid and food being pushed back up. Lemon water was probably not helping either. All of this could have been causing my nausea and discomfort.
Not sure what to tell you. When this hits me, I fast for half day to a day and just drink broth (home made out of: chicken legs – they have more fat, and veggies such as kale, cabbage, potato – you don’t eat it, carrot – also you don’t eat it, onion, garlic, zucchini etc.) and by the next day I get better and restore some of the appetite. I noticed too much fiber gets me so I reduce it for a while, eat more of the cooked veggies instead of raw and by day three I can eat normal again… until it gets me once again.
