Debunking Detox Diets and Embracing the Body’s Natural Cleansing Processes

Debunking Detox Diets and Embracing the Body’s Natural Cleansing Processes

By Thrive Wellness Reno Registered Dietitian Laura Oberg, RDN, RYT, MFA

Coinciding with the clean eating movement, “detoxes” or “cleanses” are diets that have garnered popularity as a way to reset and refresh the body after eating “bad” or “unhealthy” foods. Neither “good” nor “bad,” food is fuel for the body and mind, and these diets can be detrimental as they encourage disordered eating behaviors while also disrupting a person’s relationship with food and their body. Truthfully, the body is adept at removing waste products on its own. Thus cleanses seem to be yet another ploy by the diet industry to exploit the body image struggles that many experience while also providing a quick and costly “fix.”


Detoxes are popular eating strategies that claim to eliminate unwanted food by-products in the body. They usually involve restricting solid food, drinking juices and other liquids, and sometimes using laxatives or other means of “cleansing the colon.” 

The intentions of those who embark on cleanses vary. Some might be persuaded to believe that the diets give the digestive system a chance to rest and allow the body to deep-clean on a cellular level. Other common motivators include losing weight, increasing energy, and feeling healthier. Individuals may also be attracted to the short-term nature of a detox diet as they generally last only a few days, but typically promise fast results. 


Despite the alleged benefits, research shows that cleanses don’t actually result in toxin elimination or weight loss. Instead, detoxes often exclude vital nutrients from a person’s diet that are necessary for bodily processes and optimal functioning. For instance, drinking only juice can reduce an individual’s fiber intake, a substance that is required for healthy digestion. Additionally, cleanses can confuse individuals’ natural hunger and fullness cues, disrupting their ability to intuitively nourish their bodies in the most effective ways.

The harmful effects of detox and cleanse diets include:

  • Cyclical fasting and binging: Detox diets promote a restrictive mentality that can lead to deprivation behavior. When this occurs, the mind believes that the body is deprived of adequate nourishment, and individuals are more likely to engage in overeating followed by compensatory food restriction, which can develop into a toxic cycle and even an eating disorder.
  • Rebound effect and risk: Upon finishing a cleanse, a person can quickly regain any weight lost while dieting. Often this weight regathers around vital organs which heightens the risk for many chronic diseases.
  • Slower metabolism or starvation response: When malnourished, the body attempts to conserve energy by slowing the metabolism and burning fewer calories. A severe starvation response can cause the body’s tissues to atrophy and organs to stop functioning properly, eventually resulting in death.
  • Yo-yo dieting: The intense and quick nature of detoxes can be addicting to some, causing them to continually engage in rounds of cleanse diets followed by returns to normal eating patterns. With each change in eating patterns, a person can become increasingly disconnected from their body. 


Fortunately, the body already has natural cleansing processes in place. For instance, in the kidneys, toxins in the blood are filtered regularly. Toxin elimination also occurs in the liver where waste is prepared for excretion from the body. 

Some healthy ways to promote natural cleansing and foster a sense of rejuvenation include:

  • Eat intuitively: When you’re able, take time to prepare foods that you enjoy, eat enough food consistently according to your hunger and fullness cues, and choose foods from a variety of food groups. 
  • Plan a day of rest and self-care: Say no to requests for your time, keep your obligations minimal, and slow down. In doing so, you can give yourself a reset, reduce stress levels, and feel refreshed.
  • Practice self-kindness: Speak to yourself kindly, so that negative self-talk doesn’t cloud your perspective. By treating yourself with self-compassion, you’re less likely to feel less stressed, anxious, and depressed. Instead, you’ll feel energized and ready to embrace life authentically. 
  • Prioritize sleep: Sleep has so many benefits to mental and physical health, including enhancing the body’s toxin elimination mechanisms. While sleeping, the liver works diligently to remove contaminants from the body.
  • Stay hydrated: Water allows toxins to move out of the body through urination, sweat, and breathing. 
  • Engage in mindful movement: Physical activity reduces inflammation that can interfere with the body’s detoxification system. When choosing your movement activity, be sure it brings you joy and makes you feel good.
