A detox diet can be a great way to eliminate all of the toxins out of your body. The typical detox diet is a short term diet, consisting of 3-21 days. While it seems that a detox diet is a quick way to lose weight, it can be detrimental to the body if not done properly. To ensure that you start a detox diet correctly, it is best to speak with your physician beforehand. After getting permission, start slowly. Gradually eliminate solid foods and incorporate liquids into your diet regimen. Liquids such as fruit and vegetable smoothies are perfect for a detox diet.
