Enough. If your body was 'full of toxins' you would at best, be very ill and at worst, dead. See: septicemia.
The word 'detox' belongs in a hospital or drug-dependency unit.
If you mean 'keep yourself as healthy as possible' then by all means...
- keep hydrated - with water. Diet coke doesn't count people.
- don't smoke
- eat well - at the very least minimise sugar and white carbs
- exercise (or just go for a bloody walk/have a good regular stretching session)
- get enough sunshine or supplement with vitamin D
