SGLT-2 inhibitors, orlistat, phentermine/topiramate, metformin, tirzepatide, and Gelesis100 demonstrate varying degrees of efficacy in weight management, with SGLT-2 inhibitors showing mild but significant weight loss in non-diabetic obese patients.

Several other medications besides GLP-1 agonists can help with weight loss, including SGLT-2 inhibitors, orlistat, phentermine/topiramate, metformin, tirzepatide, and Gelesis100. Their effectiveness varies, with some showing significant weight loss and others showing mild but significant benefits. These options provide additional choices for patients who may not be candidates for or respond poorly to GLP-1 agonists.
