Here’s a **clear, evidence‑based summary of what **Should you do a cleanse? | UCLA Health says — and what experts generally advise:
🧠 What a “Cleanse” Really Is
A cleanse or detox diet refers to eating only certain foods (like juices or soups), fasting, or taking supplements with the idea of eliminating toxins from your body. Popular types include:
- Liquid cleanses: juice, smoothies, or soups
- Herbal or liver “detox” products
- Colon cleanses using laxatives or herbs
Most of these lack scientific proof that they actually remove harmful toxins. Your body already detoxifies itself through the liver, kidneys, digestive system, sweat, and urine. (UCLA Health)
👍 Possible Benefits (Short‑Term and Contextual)
Some people feel better after a cleanse — but that doesn’t necessarily mean the cleanse “detoxified” your body. Benefits may come from:
- Eating more whole foods like fruits and vegetables
- Cutting out processed foods, sugar, and alcohol for a short period
- Boosting intake of vitamins and minerals if you normally don’t eat enough produce
- Breaking unhealthy food habits or identifying food sensitivities by eliminating foods then adding them back in slowly
These effects are valid, but they come from improved nutrition and temporary calorie reduction — not from removing toxins. (UCLA Health)
👎 Risks and Drawbacks
Experts emphasize that many cleanses aren’t necessary — and some can be unsafe:
⚠️ No Scientific Evidence of “Toxin Removal”
There’s no credible evidence that dietary cleanses remove environmental toxins or harmful chemicals from the body. The liver and kidneys already do this efficiently. (UCLA Health)
💡 Potential Negative Effects
- Low calorie intake → fatigue, weakness
- Unbalanced nutrients → lack of protein, healthy fats, minerals
- Dehydration (especially with laxative‑based colon cleanses)
- Digestive issues (from laxatives, fiber imbalances, or gut microbiome disruption)
- Blood sugar swings from juice‑only diets
- Some cleanses contain unregulated supplements that could be harmful or interact with medications. (Healthline)
👩⚕️ Who Should Not Cleanse
Cleanses can be particularly risky for:
- People with diabetes or blood sugar disorders
- Pregnant or breastfeeding individuals
- Children and adolescents
- Older adults
- Those with eating disorders or a history of disordered eating
- People with chronic health conditions
Doctors generally recommend talking to a healthcare provider first before trying any cleanse. (UCLA Health)
💡 So, Should You Do a Cleanse?
Not really — at least not in the sense of “detoxing” your body.
Cleanses aren’t necessary for detoxification because your body already has systems that do this naturally. Any benefits seen are usually due to temporary dietary changes rather than the cleanse itself. (UCLA Health)
✔ A short, balanced reset (e.g., more fruits/vegetables and fewer processed foods) might help you re‑establish healthier habits.
❌ Extreme or prolonged fasting, heavy laxatives, or unregulated supplements aren’t recommended without medical supervision. (UCLA Health)
🥦 Better Long‑Term Approach
Instead of periodic cleanses, most health professionals recommend:
- Eating plenty of whole foods (vegetables, fruits, lean proteins, whole grains)
- Staying well hydrated
- Minimizing added sugar, processed foods, and excessive alcohol
- Getting regular exercise and sleep
These habits support your body’s natural detox systems and overall health much more effectively than short‑term cleanses. (UCLA Health)
