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

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.”

WHAT ARE DETOX AND CLEANSE DIETS?

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. 

THE DOWNSIDES OF DETOX AND CLEANSE DIETS

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. 

THE BODY’S NATURAL CLEANSING PROCESSES

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.

6 Ways to Help Your Teen Open Up About Mental Health
August 21, 2025
When Emma was 8, her parents noticed her food choices shrinking. At first, they assumed it was just picky eating — “She’ll outgrow it,” friends said. But by 10, Emma would only eat crackers, cheese, and chicken nuggets. Family dinners became nightly struggles, her growth slowed, and she skipped birthday parties to avoid “strange food.” Her parents felt powerless, her brother grew frustrated, and outings dwindled. What began as food avoidance soon reshaped the rhythm of the entire household. When children avoid food, most parents expect it’s a passing stage. But when restriction deepens, shrinks to only a few “safe foods,” and begins affecting growth or health, families suddenly find themselves in unfamiliar territory. This is often where Avoidant/Restrictive Food Intake Disorder (ARFID) emerges — with effects that extend far beyond the plate. As providers, we need to be attuned to these patterns. It’s tempting to dismiss them as “no big deal,” yet for many families, they are life-altering. Sadly, Emma’s story is not unusual. Mealtimes as Battlegrounds Families living with ARFID often describe mealtimes as emotionally charged, exhausting, and unpredictable. What should be a chance to connect around the table can feel more like a negotiation or even a standoff. Parents wrestle with whether to push their child to try a new food or give in to the same “safe foods” again and again to avoid tears, gagging, or complete meltdowns. This ongoing tension can make mealtimes dreaded rather than cherished. Siblings, too, are affected. Some may feel resentful when family meals are limited to what only one child will tolerate. Others may act out in response to the constant attention the child with ARFID receives. Over time, the dinner table shifts from a place of nourishment and bonding into a stage for conflict, anxiety, and guilt — a pattern that can erode family cohesion and resilience. Social Isolation and Missed Experiences ARFID impacts more than what happens at home; it influences how families engage with the world around them. Everyday events — birthday parties, school lunches, vacations, even extended family dinners — become sources of stress. Parents may pack special foods to avoid confrontation or, in many cases, decline invitations altogether to protect their child from embarrassment or overwhelm. This avoidance can lead to an unintended consequence: isolation. Families miss out on milestones, friendships, and traditions because of the unpredictability surrounding food. The child may feel left out or ashamed, while parents grieve the loss of “normal” family experiences. This social withdrawal can compound the anxiety already present in ARFID and deepen its impact across generations. Emotional Toll on Parents The emotional strain on parents navigating ARFID is significant. Many describe living in a constant state of worry — Will my child get enough nutrients? Will they ever grow out of this? Am I doing something wrong? This worry often spirals into guilt and self-blame, particularly when outside voices dismiss the disorder as mere “picky eating.” In addition, the pressure to “fix” mealtimes can strain marital relationships, creating disagreements over discipline, feeding strategies, or medical decisions. Parents may also feel emotionally depleted, pouring all their energy into managing one child’s needs while inadvertently neglecting themselves or their other children. Without support, this chronic stress can lead to burnout, depression, and disconnection within the family system. The Role of Providers For clinicians, ARFID must be viewed not only as an individual diagnosis but as a family-wide challenge. Effective care requires attention to both the clinical symptoms and the family dynamics that shape recovery. Parent Support: Educating caregivers that ARFID is not their fault, offering psychoeducation, and helping them reframe mealtime struggles as part of the disorder — not a parenting failure. Family-Based Interventions: Coaching families in structured meal support, communication strategies, and gradual exposure work so parents don’t feel powerless. Holistic Care: Involving therapists, dietitians, occupational therapists, and medical providers ensures that the family does not shoulder the weight of treatment alone. When families are validated, supported, and given practical tools, the entire household can begin to heal. Treatment is not only about expanding a child’s food repertoire but also about restoring peace, resilience, and connection at home. Moving Forward ARFID may begin with one individual, but its ripple effects are felt across the entire family system. By addressing both the psychological and relational dimensions, providers can help transform mealtimes from a source of conflict into an opportunity for healing and connection. For those who want to go deeper, we invite you to join our upcoming training on ARFID , where we will explore practical strategies for supporting both clients and their families.
