In the quest for sustainable weight loss, many individuals encounter the phenomenon known as the yo-yo effect. This cycle of weight loss followed by weight regain can be frustrating and demoralizing, yet its underlying mechanisms offer valuable insights into the complexities of metabolism and behaviour. In this article, we delve into the science behind the yo-yo effect, exploring how it works and its implications for both weight management and overall health.
The yo-yo effect, also referred to as weight cycling, describes the pattern of losing weight through dieting or other means, only to regain it shortly afterwards, often surpassing one's initial weight.

This is described by our genetics, hormones, behaviour, and environment.
Your metabolism works at the rate that supports this set point so when you go on a "diet", you lose weight till the body adjusts to working with fewer calories and then the weight loss stops. Now you need to reduce intake further. The response to dieting manifests as: Metabolic Adaptations: When the body experiences rapid weight loss, it responds by slowing down metabolism to conserve energy.
This adaptive response evolved as a survival mechanism during times of food scarcity but can hinder weight loss efforts in modern times. As a result, fewer calories are burned at rest, making weight maintenance increasingly challengin.
