Detoxification (detox) diets are more popular than ever.

These diets claim to cleanse your blood and eliminate harmful toxins from your body.
However, it is not entirely clear how they do this, what specific compounds they’re supposed to eliminate, and if they even work.
Read on for a detailed review of detox diets, including their benefits and side effects.
What is a detox?
Detox diets are generally short-term dietary interventions designed to eliminate toxins from your body.
A typical detox diet involves a period of fasting, followed by a strict diet of fruit, vegetables, fruit juices, and water. Sometimes a detox also includes herbs, teas, supplements, and colon cleanses or enemas.

This claims to:
• rest your organs by fasting
• stimulate your liver to get rid of toxins
• promote toxin elimination through feces, urine, and sweat
• improve circulation
• provide your body with healthy nutrients

Detox therapies are most commonly recommended because of potential exposure to toxic chemicals in the environment or your diet. These include pollutants, synthetic chemicals, heavy metals, and other harmful compounds.
These diets also claim to help improve your immune system, digestion, energy levels, and aide in weight loss.
However, human research on detox diets is lackingTrusted Source, and the handful of studies that exist are significantly flawed.
The most common ways to detox
There are many ways to do a detox diet — ranging from total starvation fasts to simpler food modifications.

Most detox diets involveTrusted Source at least 1 of the following:
• fasting
• only drinking juices
• using dietary supplements
• using enemas or laxatives to cleanse the colon
• using herbs
• avoiding all allergenic foods, then slowly reintroducing them
• using a sauna

Detox diets can vary in intensity and duration.
Which toxins are eliminated?
Detox diets rarely identify the specific toxins they aim to remove. The mechanisms by which they work are also unclear.
In fact, there is little to no evidenceTrusted Source that detox diets remove any toxins from your body.

What’s more, your body is capable of cleansing itself through the liver, feces, urine, and sweat. Your liver makes toxic substances harmless, then ensures that they’re released from your
body.

Despite this, there are a few chemicals that may not be as easily removed by these bodily processes, including persistent organic pollutants (POPs), phthalates, bisphenol A (BPA), and heavy metals.
These tend to accumulate in fat tissue or blood and can take a very long time — even years — for your body to flush.
However, these compounds generally are removed from or limited in commercial products today.

Overall, there is little evidence that detox diets help eliminate any of these compounds.
How effective are these diets?
Some people report feeling more focused and energetic during and after detox diets.

However, this improved well-being may simply be due to eliminating processed foods, alcohol, and other unhealthy substances from your diet.
You may also be getting vitamins and minerals that were lacking before.
That said, many people also report feeling very unwell during the detox period.
