You have been away on holiday for 3 weeks, indulging in a little too much alcohol and processed foods, and you have come home feeling a bit ‘squishy’ and all round like your body is in dire need of some TLC.
But never fear, because the week you get back you are going to get knees deep in the latest and greatest detox cleanse!!
Hear the word detox diet and you get polarizing opinions:
-The first being that they are wonderful- gods gift to weight loss and all round health and vitality!
- The second being that they are an absolute load of money wasting crap (or something along those lines).
So who is right?
What is the aim of a detox anyway?
The aim of a detox is more or less to rid your body of toxins. But what on earth is a toxin exactly?
Toxins are compounds that interact at a molecular or tissue level to alter the homeostasis of an organism which thereby results in an alteration in normal functioning. But here’s the kicker that most people often overlook: Any compound has the potential to cause harm, depending on the amount and level of exposure (1). So while when you think of toxins you may think of drugs or the likes, water or even spinach- if consumed in a high enough dose can be toxic. Thereby meaning anything and everything has the potential to be toxic to a certain extent; there is no way to avoid this.
However don’t panic too much as the body is (in most people) excellent at detoxing itself. When we think of detoxification we often think of the liver, as this is where many compounds are sent to be broken down into forms that we can excrete from the body.
So if our bodies were so good at detoxification why would a detox even be necessary?
Many people believe that because nowadays we are exposed to so much harmful stuff such as cigarette smoke, too much alcohol, pollution and medications it is helpful to give our bodies a little help when it comes to detoxing.
Many many many people (and by many I mean everyone I’ve ever known who has done a detox diet) aren’t doing it to give their digestive systems and liver a break but are doing it to lose body fat. You may be different but you are definitely the minority.
Embarking on a ‘detox diet’ in an attempt to lose body fat is probably going to leave you rather disappointed. Majority of weight lost from a detox diet is probably water, glycogen stores and intestinal bulk- all of which return shortly after getting your eating pattern back to normal. One study in particular found that a 7 day juice cleanse saw a decrease in LDL and VLDL cholesterol however this returned to normal one week after ending the cleanse. (2). Not to mention detoxes can bring about feelings of deprivation from the increased effort and reduced calories, which can lead to bingeing and can often create an unhealthy feast or famine style of eating (1) (the ‘diet starts tomorrow so I must eat all this unhealthy food filled with toxins to get the cravings out of my system’ mentality sound familiar?).
So even if you are someone who generally just wants to go on a detox diet to give your detox pathways of the liver some support, are you going to benefit?
In majority of cases a natural, unprocessed and organic diet is going to support the bodies natural detox processes.
There are specific instances where additional detoxing may be required (after heavy medication use, or heavy metal poisoning for example) however this would be a job for a registered practitioner to address the specific problem with specific remedies as opposed to the usually hideously expensive ‘one size fits all’ detox products on the market. Besides most detox diets are sold on the misguided premise that our bodies do not detox efficiently all the time, which in the vast majority is completely incorrect (3).
A much better solution is to try and support your bodies natural detox pathways daily through natural, whole and unprocessed foods whilst limiting your exposure to harmful things you have control over (processed food, drugs, cigarette smoke, pesticides etc.), instead of hammering your body for majority of the year and thinking that a ‘one size fits all’ detox program for 3 weeks is going to undo all of that damage.
