A detox diet is a very popular option for weight loss as it helps to eliminate fluid accumulated in the body, which can reduce swelling. Many people opt for a detox following a period of prolonged medication use, or after a period of over-eating (like after holidays or at the end of the year). It can also used to prepare the body for a new, re-vamped diet with food re-education.

A detox diet should be divided into 3 phases. The main focus of a detox diet is to increase your intake of organic and low-fat foods, and to avoid processed products that are high in salt, fat, sugar, gluten, dairy and chemical additives.

During the detox, you should increase your intake for fruits, vegetables and legumes, which are rich in fiber, antioxidants and minerals. These will help to strengthen the immune system and contribute to your well being.Other benefits include improved sleep quality, and reduced risk of illnesses like cancer, obesity and diabetes.

It is important to highlight that there are few studies that prove that a detox diet can provide you with health benefits. Therefore, if your goal is to lose weight, you should see a registered dietitian for assessment to determine your nutritional needs and develop a customized plan.
