A recent study suggests that rapid weight loss could be more effective than gradual weight loss. Researchers discovered that individuals who shed pounds quickly tend to achieve greater weight reduction compared to those who lose weight slowly.
Furthermore, those who undergo rapid weight loss are more likely to sustain their weight loss one year after the program. This finding challenges the traditional belief that gradual weight loss yields better long-term results, as highlighted by an expert.
The study, presented at the European Congress on Obesity in Turkey, analyzed the outcomes of a rapid weight loss regimen versus a gradual weight loss plan. Norwegian experts studied 284 obese adults who were divided into the two programs.
During the 16-week rapid weight loss program, participants were restricted to 1,000 calories per day in the initial eight weeks, 1,300 calories per day in weeks nine to 12, and 1,500 calories per day in weeks 13 to 16. On the other hand, the gradual weight loss group was advised to reduce their daily calorie intake by 1,000 calories, with self-reports indicating an average consumption of around 1,400 calories per day.
According to NHS.uk, the typical daily calorie requirements are 2,500 for men and 2,000 for women. Following the 16-week weight loss phase, both groups engaged in a 36-week program designed to prevent weight regain.
The research team observed that participants in the rapid weight loss program lost a significantly higher percentage of their total body weight compared to those in the gradual weight loss group. After one year, the rapid weight loss group had lost 14.4% of their body weight, while the gradual group had lost 10.5%.
Lead author Dr. Line Kristin Johnson from Vestfold Hospital Trust in Norway stated that the study challenges the notion that slow, gradual weight loss is necessary to avoid weight regain and reduce obesity-related complications. The results imply that rapid weight loss, when supervised professionally, may be more effective for achieving weight loss targets associated with lower obesity-related health risks.
Dr. Marie Spreckley, a research program manager at the University of Cambridge, emphasized the importance of the study in questioning the belief that gradual weight loss is superior. She noted that evidence is growing in favor of rapid weight loss as a viable obesity treatment strategy when implemented safely within a structured program.
