Unpacking the Science of Detox Diets: A Dietitian’s Perspective on New Year

The word “detox” is one of the most searched-for terms in the world today. It’s no mystery why: The idea that we can cleanse our bodies and improve our health by eating certain foods and avoiding others is an appealing one. The problem? Detox diets have been shown to be ineffective at best, and dangerous at worst. Here’s what you need to know about detox diets so you can make an informed decision about whether or not they’re right for you:

What is a detox diet?

A detox diet is a group of eating plans that claim to cleanse the body. Detox diets can be short-term or long-term, and their effectiveness varies from person to person. Some call them “cleanse” diets, while others use the term “detox.” They’re not the same as healthy eating or juice cleanses.

A detox diet may involve restricting certain foods and beverages for a certain period of time (for instance, 48 hours), as well as exercise and other activities intended to help you lose weight or clear out toxins from your body.

What are the health claims of detox diets?

The health claims of detox diets are many and varied, but here are some of the most common:

  • Losing weight. Detox diets claim to help you lose weight by making you eat fewer calories than normal or by increasing the rate at which your body processes food (which can cause nausea). Some people believe that this weight loss is due to burning fat stores in the body, especially after eating certain foods or beverages. However, there is no scientific evidence that this happens during a detox diet; rather it’s mostly psychological—people feel better about themselves after they achieve their goal weight!
  • Detoxing your body. According to some theories behind these diets (and many others), we’re made up of trillions upon trillions of cells that contain chemicals called toxins; these toxins build up over time as part of everyday living until we’re exposed to them again through exposure at work or play (for example), then our bodies go into “fight mode” against whatever foreign chemicals might be present within our system at any given moment so as not allow them entry into our bloodstreams via its lymphatic system channels located throughout organs such as lungs/lungs, etc…

How do detox diets work?

Detox diets are not based on any scientific evidence. They may be dangerous, causing electrolyte imbalances, dehydration, and malnutrition. Some people report weight gain while others experience kidney damage during the process of detoxification.

Do detox diets have any health benefits?

Detox diets are not recommended, and they can cause harm.

The science is clear: Detox diets are not supported by scientific evidence. The American Dietetic Association states that a balanced diet is best for your overall health, and detox diets don’t necessarily meet that requirement. These types of programs can be dangerous for people with diabetes or heart conditions—and the results aren’t always worth it.

Are there any risks associated with detox diets?

Detox diets can be dangerous. They may cause electrolyte imbalances, dehydration, muscle breakdown, and liver damage.

It’s important to note that not all detoxes are created equal: some are more extreme than others and require greater amounts of time or effort (and therefore more risk). For example, a juice fast might last two or three days while an apple cider vinegar cleanses will usually last longer—upwards of three weeks depending on the individual’s results. This is because juicing removes water from your body in order to achieve rapid weight loss; however it also causes electrolyte imbalances which can lead to dehydration if not corrected quickly enough (i.e., within 24 hours).

Detox diets can be dangerous and should be avoided by people just trying to get healthy, especially those with diabetes.

Detox diets are not a good way to lose weight, improve your health or achieve any other desired goals. In fact, they can be dangerous and should be avoided by people just trying to get healthy.

Dietitians have concerns about the potential risks associated with detox diets as well as nutrient deficiencies and electrolyte imbalances that may occur during these short-term regimens.


While I can’t say that detox diets are a bad idea, I do think it’s important for people to understand what they’re getting into and make sure they have the proper medical support before embarking on one. Detox diets can be dangerous, especially for those with diabetes or any other chronic condition. If you’re looking to lose weight and improve your health, there are much safer ways than going on a detox program–like following this 7-day plan from Prevention magazine!
