Is this the next big thing?
In the United States, over 70% of adults are either overweight or living with obesity, a number that continues to grow. This rising trend has sparked scientific interest in discovering effective, accessible methods for weight management. While popular treatments like GLP-1 medications are gaining attention, they often come with high costs, making them inaccessible for many individuals seeking sustainable weight loss options.
A recent study turned its focus to collagen, a low-cost protein supplement commonly used to support joint health and skin elasticity. Researchers wanted to understand if collagen could also aid in weight loss when combined with a healthy eating plan. Over a 12-week period, they monitored participants who took collagen and compared their results with a control group that followed the same diet without supplements. Collagen was provided through protein bars consumed twice daily by the test group.
The study involved 64 adults classified as overweight or mildly obese. All participants adhered to a Mediterranean-style diet rich in whole foods, lean proteins, and healthy fats. Those in the test group consumed 20 grams of bovine collagen daily through protein bars, adding slightly more calories to their diet than the control group. Both groups underwent regular assessments, including body weight, blood pressure, and metabolic health markers.
Findings showed the collagen group lost more weight than the control group—an average of 6.6 pounds versus 3.3 pounds. In addition to weight loss, participants who consumed collagen saw improvements in blood pressure, waist measurements, BMI, and liver health indicators. Notably, they also reported feeling less hungry and more satisfied after meals. Importantly, these benefits came without a loss in muscle mass, a common concern in weight reduction efforts.
Despite these promising outcomes, the study had limitations, including the involvement of researchers connected to the company that produced the protein bars. Health experts offered cautious optimism: Dr. Mir Ali highlighted the positive aspects of using collagen in meal replacements but emphasized the need for further research to isolate collagen’s specific effects. Dr. Hector Perez added that collagen supplements are generally safe, although individuals with kidney conditions should use them carefully. Both doctors agreed that collagen may be a helpful addition to a broader weight management plan but should not replace fundamental lifestyle changes like exercise and portion control.
