Detoxing diets: myths vs reality

Sue Scharf of NHC Health Centre Northcliff writes:

Detox diets are regularly punted as an all-round cure. It’s a popular remedy for people who feel run-down, lethargic, bloated or like they are carrying more extra weight than they should.

“Reset your metabolism to factory settings”, and “cleanse on the inside without feeling hungry”, are among the numerous descriptions you will find for detox diets.

Typical detox diets are usually short-term, and not intended as a permanent way of life. They range in length from a few days to three months.

The type and method of detoxing will vary from diet to diet, but generally involves some form of fasting or drinking only fluids for a set time period. Some detox diets allow some foods – usually fresh fruits and vegetables, and/or vegetable/fruit juices. The logic used by the authors of these diets is that taking in only fluids aids the body to flush itself of toxins.

The basic fact is that normal functioning bodies do not need assistance to flush away waste products. The body cleans itself naturally and automatically unless the liver or kidneys have failed. And in a case like this, hospitalisation or dialysis may be necessary, not a detox diet.

Those following a fad-detox diet often report horrible symptoms. They experience low energy levels, low blood sugar, muscle aches, feeling dizzy and light-headed, headaches, nausea, hunger and weakness.

These symptoms are a sign that the body is running low on fuel, which could cause serious damage to the body, and possibly even result in injury.

There are many other ways to get your body healthy and “clean”, even after a lengthy period of unhealthy living. Developing a good routine of planning, healthier food choices throughout the day, drink plenty of water and exercise consistently. These are the things that will make you feel good. Energy, vigour and good health will be your reward.

Short-term detox diets can be damaging and energy-depleting. Carried out for longer periods, they carry potential serious consequences such as injury-on-duty or even driving accidents as they rob you of energy and cause you to feel ill.

The truth is that your body is already an expert at eliminating toxic substances from your system – no matter what you eat or drink. Toxins do not build up in your liver, kidneys, colon or any other parts. The body has an inbuilt process that works efficiently to eradicate all toxins and waste products.

Detox diets also do not improve cholesterol levels, prevent heart disease, help treat diabetes or sort out colon disorders.

A detox diet is dangerous for those with diabetes, and may cause severe low blood glucose levels with subsequent long-term damage.

Consult with a registered dietician, should you experience any symptoms such as chronic fatigue, lethargy, bloating, colon cramps, abdominal discomfort etc, who will assist you in designing a tailor-made, individualized eating plan that will assist in alleviating those symptoms.
