Many people trying to lose weight believe that rapid weight loss almost inevitably leads to regaining the weight just as quickly. However, a new study has shown that this common assumption may not be true. Scientists concluded that rapid weight loss can be just as effective and sustainable as gradual weight reduction.

The study, published in The Lancet Diabetes & Endocrinology, analyzed data from several clinical trials and weight-loss programs. The researchers found that people who lost weight more quickly during the first months of treatment maintained their results in the long term just as successfully as those who lost weight slowly and gradually.

The authors note that noticeable early success may play an important psychological role. Rapid weight loss can increase motivation, strengthen self-confidence, and help people stick to their chosen diet and physical activity plans for longer periods. In contrast, very slow progress often leads to disappointment and reduces commitment to the program.

The researchers emphasize that the key factor is not the speed of weight loss itself, but whether the chosen approach is realistic and safe.

If weight reduction takes place under professional supervision and includes adequate nutrition, preservation of muscle mass, and regular physical activity, a fast start does not necessarily mean future weight regain.

Scientists also point out that even if some weight returns over time, this does not eliminate the health benefits. Losing weight helps lower blood pressure, improve blood sugar levels, reduce stress on the joints, and decrease the risk of cardiovascular disease.

The authors of the study believe that doctors should move away from the outdated idea that “slower is always better.” For many patients, a more intensive start to a weight-loss program may be not only safe, but also more motivating, increasing the chances of long-term success.
