The Claim
It is believed that prebiotics can lead to substantial weight loss by altering gut microbiota and improving metabolism.
Origin
This myth is perpetuated by selective interpretation of studies and sensationalized claims in weight loss supplements marketing.
What Science Says
Research indicates that while prebiotics can aid in weight management, the effects are modest. A meta-analysis of clinical trials shows small but statistically significant weight reduction, suggesting prebiotics may support other weight loss strategies, not be solely responsible (Kellow et al., 2014).
Verdict
Mostly False
