The Dangers of Crash Dieting

Crash dieting, characterized by severe caloric restriction, can lead to rebound weight gain and may accelerate fat accumulation once normal eating resumes. This cycle, also known as yo-yo dieting, results in a permanent decline in metabolic rate and basal temperature, which further complicates weight management. An illustrative example of this phenomenon can be seen with contestants from 'The Biggest Loser', many of whom regained more weight than they lost after the show's conclusion, despite eating at what should have been their appropriate maintenance levels. Their severely slowed metabolisms failed to return to normal, leading to continued weight gain over the years.
