Ideally one should be on a detox diet for a week, every three months, but you can also detox every weekend.
"If you are obese and suffering from chronic diseases then you are vulnerable to bingeing. So you can detox every weekend. If you have high cholesterol, diabetes and blood pressure, detox every two months. And if you are leading a stressful life, make sure you do it on quarterly basis."
And while on a detox diet, you must avoid caffeine, food stuff with preservatives, sugar and fatty junk food. So no alcohol and so smoking.
