So just water and salt for 21 days?
Discussion
No salt
21 days would probably be too long for me, are you very fit or carrying extra weight?
Trying to understand why you would go that long 🤔
Not like marathon fit but walking 15-20 miles a week, occasional 4 mile run and gardening chores which can be a workout digging, moving mulch, compost etc. My weight was upper 150s @ 5'9" not really "overweight" but not ideal either. My motive was the challenge/discipline of it along with a deeper cleansing than I could get in 7 days.
