Collagen as a Weight-Loss Supplement: A Breakthrough Study
A recent study presented at the European Congress on Obesity (ECO 2025) and published in the journal Nutrients has shed light on the potential of collagen as a safe and effective weight-loss supplement. The research, conducted by Dr. Paola Mogna-PelĂĄez and colleagues from the University of Navarra in Pamplona, Spain, revealed promising results that could revolutionize the weight-loss industry.
The study involved 64 individuals with overweight or obesity, aged 20â65 years, who were randomly assigned to two groups. One group was instructed to consume protein bars enriched with collagen, while the other group served as the control. Both groups received healthy eating advice based on the Mediterranean diet.
Over the course of 12 weeks, the participants who consumed collagen-enriched protein bars experienced significant weight loss compared to the control group. They lost twice as much weight, saw improvements in blood pressure, waist circumference, and liver health, and may have increased skeletal muscle and fat-free mass. These results are particularly noteworthy considering that both groups consumed the same number of calories.
The collagen used in the protein bars was derived from cows and had been modified to absorb extra water, allowing it to expand in the stomach. This expansion created a feeling of fullness, reducing appetite and ultimately leading to weight loss. Additionally, the collagen-enriched protein bars were well-received by the participants, with high ratings for taste.
One of the key findings of the study was that the weight loss in the collagen group was not attributed to muscle loss. In fact, the participants in this group may have built muscle, which is essential for boosting metabolism and burning more calories. The researchers also noted that collagen could potentially alter the composition of gut bacteria, further aiding in weight loss and appetite control.
The study results have paved the way for collagen-enriched protein bars to be marketed as a weight-loss aid. The researchers are now conducting a larger trial to delve deeper into the mechanisms of action, particularly in relation to the gut microbiota. This groundbreaking research could have far-reaching implications for individuals looking to achieve sustainable weight loss in a safe and cost-effective manner.
In conclusion, collagen has emerged as a promising weight-loss supplement with the potential to revolutionize the way we approach weight management. With further research and development, collagen-enriched products could offer a safe and effective solution for individuals struggling with overweight and obesity. Stay tuned for more updates on this exciting breakthrough in the field of weight loss.
