A recent study discovered that rapid weight loss may be more effective than gradual weight loss. Researchers found that individuals who shed pounds quickly tend to experience greater weight reduction compared to those who lose weight slowly.
Moreover, those who opt for rapid weight loss are more likely to maintain their weight loss over a year. This challenges the traditional belief that gradual weight loss yields better long-term results, as stated by an expert.
The study, presented at the European Congress on Obesity in Turkey, evaluated the effects of a rapid weight loss regimen versus a gradual weight loss plan. Norwegian experts analyzed data from 284 obese adults who were divided into the two programs.
During the 16-week rapid weight loss plan, participants were restricted to 1,000 calories per day in the initial eight weeks, followed by 1,300 calories for weeks nine to 12, and 1,500 calories for weeks 13 to 16. In contrast, the gradual weight loss group was advised to cut back on 1,000 calories daily, with self-reported daily intake around 1,400 calories.
According to NHS.uk, the average 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 group achieved significantly higher weight loss during the initial 16 weeks compared to the gradual weight loss group. Specifically, the rapid weight loss group lost 12.9% of their total body weight, while the gradual group lost an average of 8.1%. After a year, the rapid weight loss group maintained a 14.4% weight loss, surpassing the gradual group’s 10.5% loss.
Lead author Dr. Line Kristin Johnson from Vestfold Hospital Trust in Norway stated, “Structured rapid weight loss programs resulted in greater weight loss at one year for obese adults.” She emphasized that rapid weight loss, when supervised professionally, could be more effective than gradual weight loss in achieving significant weight loss goals and reducing obesity-related health risks.
Dr. Marie Spreckley, research program manager at the University of Cambridge, praised the study for challenging the notion that gradual weight loss is more beneficial in the long run. She highlighted the growing evidence supporting the effectiveness of safe and structured rapid weight loss programs as a viable strategy for treating obesity.
The study underscores the potential of accessible commercial weight reduction programs in alleviating the strain on public healthcare systems and providing effective weight loss and maintenance solutions for individuals battling obesity.
