Please note:

I have been on this soup diet since March 2019 for detox to help my severe allergy.  Not only my skin feel less itchy but also my stomach feels better (I have gastritis).  On top of that, I have lost 17kg (37lbs) in 7 months without any exercise.  It's a week-long diet, and you can repeat it as you wish.  However, since it is a low-carb diet, you must consult your doctor prior to trying.  Or immediately stop and consult your doctor, if you feel weak, dizzy, and sick.  Please note that the results will vary from person to person.  It worked for me, but that doesn't mean that it works for everyone.
