Weight Regain

Meaning

Weight Regain is the prevalent clinical phenomenon characterized by the recovery of a significant portion of body weight previously lost through dedicated diet, increased exercise, or bariatric surgical intervention, often observed to occur in the months or years following the initial successful loss phase. This complex physiological event is frequently a direct consequence of the body’s powerful adaptive metabolic changes and counter-regulatory hormonal shifts that strongly favor energy conservation. Understanding the precise mechanisms driving weight regain is critically important for designing truly effective, sustainable long-term weight management protocols.
