A diet based on detoxification shakes and other drinks may damage the digestive system and deprive the body of energy and nutrients, according to Northwestern University. Individuals may not notice the harm due to the placebo effect or the energy-boosting adrenaline they produce when lacking nutrients.
The human body detoxifies itself without requiring detox drinks, which generally do not contain enough protein, reports Metro. Consumers risk wasting money on products that are ineffective or harmful. Detox drinks also often contain high levels of sugars, which disrupt blood sugar and insulin levels, notes Women's Health. An increasing number of dietary and weight-loss products are entering the market containing unsafe ingredients or without proven effectiveness, warns the United States Food and Drug Administration. The FDA cannot test all detox products on the market.
