GLP-1 medications work by mimicking pure hormones within the intestine, which assist to decrease blood sugar, gradual digestion, and promote emotions of fullness to assist weight reduction.

Semaglutide and liraglutide goal GLP-1 receptors, whereas tirzepatide targets each GLP-1 receptors and one other intestine hormone, GIP. This twin mechanism could also be what’s driving better weight reduction outcomes with tirzepatide.

The researchers additionally counsel that the way in which the physique processes and interacts with the treatment might play a job in weight reduction.

“Semaglutide has been available on the market for longer and subsequently has extra sturdy, long-term knowledge on outcomes for lowering heart attacks and strokes, and likewise good proof to help a discount in renal disease,” mentioned Thompson.

Semaglutide can be out there as an oral pill, which can assist those that are averse to injections.

Oral semaglutide (Rybelsus) was the primary oral GLP-1 approved by the Meals and Drug Administration (FDA). It was initially permitted to deal with sort 2 diabetes, however may assist weight reduction. In December 2025, the FDA also approved an oral form of Wegovy particularly for weight reduction.

Regardless of the widespread success of GLP-1s for weight reduction, specialists encourage wholesome way of life habits, resembling a balanced weight-reduction plan and common train.

“Weight problems needs to be seen as a power medical situation requiring a customized therapy strategy — there isn’t a one-size-fits-all,” mentioned Thompson.
