? What is a detox diet

If you're inspired by the new year, springtime or just planning a clean start you’ve probably considered a detox. Nutritionist Kerry Torrens discusses the pros and cons of drastic diets

Thanks to celebrity endorsements and promises of a quick fix, detox diets have quite a following. Fans believe we need a break from the overload of toxins that engulf our everyday lives and that includes processed and junk food, alcohol, caffeine, sugar as well as cigarette smoke and pollution. The reason typically given for a detox is to support the body’s perceived inability to manage this overload, which detox supporters suggest might otherwise lead to weight gain, cellulite, bloating, fatigue and ill health

The diets

Ranging from fruit fasts, which cut out whole food groups to restricted short term diet plans that focus on eliminating caffeine, alcohol, salt, sugar and processed foods, you can expect to lose weight on such a diet because of the limited food choices. Most of this weight loss will be water, stored glycogen and waste products and the majority of it will be regained when you return to normal eating patterns. Some detox diets can be extreme and, when followed for a sustained period of time, may lead to dangerous nutritional deficiencies. Others that advocate the use of specific supplements can be expensive. Detox diets may also trigger unhealthy eating patterns and behaviours, especially in teenagers, which can impact long-term health and wellbeing.

The pros

There are some aspects of a ‘detox’ that can boost your health and wellbeing. As well as making you think about what and when you’re eating they can motivate you to eat more fruit and vegetables, drink more water and cut down on processed foods, caffeine and alcohol. Eating only whole, clean foods helps retrain your palate so you’re less likely to want those fatty, salty and sugary foods. Just like any diet, a set ‘detox’ can also remove triggers to eating, which can be useful, especially if you’re habit driven or an emotional or comfort eater

The cons

There is no scientific evidence to support the need or the value of a detox and that’s because our bodies are designed to repair, regenerate and detoxify themselves (though it’s obviously not a good idea to excessively overload ourselves with toxins). We have specific organs like the liver, kidneys, skin, digestive system and lungs as well as enzymes in our cells that work hard to break down and eliminate toxins and internal waste products. In fact, by cutting back on key nutrients like protein you’re far more likely to compromise rather than support your body’s ability to detoxify


With no scientific support that a detox is effective or sustainable in the long term and with the prospect of most dieters putting weight back on when they return to normal eating patterns, detox diets are not what they’re often touted to be. Nevertheless, if you have been over-doing it, cutting back on processed foods, alcohol and sugar in preference for homemade meals made from fish, lean meats, fruit, veg and whole-grains, reducing your intake of alcohol and caffeine and drinking more water will almost certainly make you feel better
