And just like that, it’s January all over again! We arrive at this point every year full of assessment, mince pies and optimism, typically reciting the same mantra ‘this is the year that I’m going to get really fit’. Gym induction booked, remaining liquor thrown away and the sweet drawer at work cleared out. The transformation begins. 

As your regular day to day conversations start to unusually centre more around healthy eating, you might find the conscious or unconscious nutritional choices of many people around you being labelled as a ‘detox’. A concept that is often associated with many glamorised case studies and testimonials. However, despite the endorsements the actual scientific research which supports this facet of nutrition for optimum weight loss and health is still very inconclusive. 

With this in mind the following short article will review ‘detoxing’ in more depth by looking at the science which underpins it, so that both sides of the debate on this diet trend can be presented in an unbiased way to empower you to make your own decisions.

To detox in a nutrition sense means to ‘rid your body of all toxins and poisons that we accumulate from food, drink, modern lifestyles choices and even through illness. As we know with the non-stop nature of the modern lifestyle it can be difficult to always avoid a food which doesn’t contain toxins in the form of pesticides, herbicides, false hormones, antibiotic residues, artificial additives and a host of other chemicals. To make things even harder we don’t just take in toxins from food, other contaminants can come from sources such as alcohol, unfiltered water, chemicals in the atmosphere, mould, clothing and even food wrapping. It sounds like the biggest game of dodgeball you’ll ever play I know! 

In a healthy person with a good diet and physical activity level (exercising 2-3 times a week), toxins will be effectively removed from the body as waste matter, urine, sweat and even through the breath. In contrast, toxin removal for others who adhere to a low activity level and consume a mostly processed diet is not quite as simple. For these individuals their ingested toxins get internally stored and often block the lymphatic (waste disposal) circulatory system. If you don’t know, your lymphatic system affects every cell and organ in your body and can be compared to a motorway, when congested, nothing moves. Blocking the 600+ lymph nodes (collection sites) contained within the lymphatic system subsequently hinders the immune system, which can lead to many illnesses, even cancer and usually results in the body retaining more ingested fats. 

To ascertain whether your lymphatic system is working efficiently look through the list of conditions below to see how many of them apply to you.

– You often suffer with minor ailments such as colds, flu’s and viruses.

– Feeling fatigued and bloated with some swelling around the arms and legs can be common.

– You seem to store cellulite in many hard to shift areas.

– Perspiring excessively at night when sleeping is a regular occurance. 

Enter the pro detox advocate who at this juncture will look to combat the 4 conditions above by promoting a low calorie natural fasting diet based on high quantities of water, fruit, vegetables or their own supplement and food replacement ranges. 

In contrast, the non-detox prescribing nutritionist will instead support an increase in physical activity and a tailored calorie reduction with a food plate consisting of organic unrefined carbohydrates, pure proteins, fruit, vegetables and unsaturated fats.  

So who is correct?

In the short-term most detox followers will see some health improvements and initial weight loss, because the low calorie intake from their food choices is being surpassed by the calories burnt off through day to day activity. However, any body composition changes are likely to come from a loss in water due to their detox diet being very low in energy (calories). One other factor to consider with detox diets is that most nutritionists only recommend following them for a short period of time, typically between 7 days and a month.

It is important not to detox for long periods because adhering to a typical low calorie detox diet can leave your body starved of energy and dangerously malnourished if you continue to exercise at a high intensity. In addition, as a consequence of a detox plan’s short life span when most followers return to a more balanced diet, the weight that has been lost previously is often regained. The reasoning for this is linked to our metabolism slowing down, which in turn means it takes longer to burn off calories and fat in the future. 

On the other side of this debate there are a lot of positive features of detox diets as well. Encouraging more people to increase their hydration (water) levels, eat more fruit and vegetables, cut out refined carbohydrates, avoid excess stimulants (coffee, fizzy drinks) and lower their intake of saturated fats is no bad thing. As these recommendations should be the backbone to any eating plan for any goal. 

Should I detox?

At this point in the article you may have been steered quite predictably to thinking that detox plans should be completely avoided. However, you might be surprised to read that in my own opinion I don’t believe this and, as an experienced health professional I have actually recommended detoxing in some form to certain clients that I have worked with. In my view, for individuals who tick most boxes on the 4 lymphatic system conditions, following many of the described detox principles will serve a lot of good. This is because their new healthier diet will help to initially break down any stored lymph which is causing gut blockages as it encourages the lymphatic system to discharge many unwanted fats. 

Despite my approval I would only recommend following the true detoxing principles that most experts recommend as a 7 to 14 day trial, this would also include an avoidance of red meat, wheat, dairy and high impact exercise. Personally I don’t advocate following a drastically reduced calorie consumption during this period either, a 500 – 1,000 calorie deficit each day eating every 2-3 hours should still be sufficient to lose weight. Following on from any detox intervention, organic wheat, dairy and red meat can start to be re-introduced, providing your body handles these foods well.
