Weight cycling, also known as yo-yo dieting, refers to the repeated loss and gain of weight. This process can be detrimental to health, as it may lead to a range of complications, including increased body fat percentage and loss of muscle mass. The potential health risks of weight cycling include higher chances of developing metabolic syndrome, fatty liver disease, and chronic conditions like diabetes. Additionally, frequent fluctuations in weight can negatively impact psychological well-being, leading to issues such as anxiety or depressed mood, making it harder to maintain a healthy lifestyle.
