Juice protocols are popular and heavily marketed, and most of what is written about them is written by people selling them. Here is a more measured version.
What we do not say
That juice cleans out your system. Your liver and kidneys do that continuously, they do not need help from a beverage, and no juice protocol has been shown to remove anything they would not have removed anyway. Any page claiming otherwise is selling.
What does seem to happen
People who spend several days without alcohol, caffeine, ultra-processed food and late eating usually feel better. That is worth having. It is also fully explained by the removal, not by the juice.
The more durable value, in our experience, is the interruption — a few days that break an eating pattern someone has been stuck in for years. Whether that sticks afterwards is the part that actually matters, and it has nothing to do with juice.
Who should not do one
Anyone diabetic, particularly on insulin or sulfonylureas — juice is concentrated sugar with the fibre removed, and this combination has caused serious hypoglycaemia. Anyone pregnant or breastfeeding. Anyone with kidney disease, where the potassium and oxalate load is a genuine concern. Anyone underweight, recovering from illness or surgery, or with a history of disordered eating.
Here, any such protocol is set by the medical team from your diagnostics, not chosen from a brochure. If you are doing one at home, speak to your own doctor first — that is not a formality for the groups above.
