What a GLP-1 does
GLP-1 is one of the hunger hormones Dr. Wood describes in why obesity is a disease: it helps tell the brain you have eaten enough. GLP-1 medications act on that same signal.
Who they are approved for
The FDA approved Zepbound (tirzepatide) for chronic weight management in adults with a body mass index of 30 or more, or 27 or more with at least one weight-related condition such as high blood pressure, type 2 diabetes or high cholesterol, used together with a reduced-calorie diet and more activity (FDA). Wegovy (semaglutide) and Saxenda (liraglutide) carry the same adult criteria on their labels (Wegovy label; Saxenda label).
What the FDA warns about
The FDA has warned about dosing errors with compounded semaglutide, and about counterfeit and fraudulent GLP-1 products (FDA). A medicine this strong belongs with a physician who knows your history and checks your labs.
How Dr. Wood decides
- Not on request. Total Body Renewal does not prescribe weight-loss medication because someone asks for it. It follows a visit, an exam and your labs.
- One option among several. GLP-1 therapy is one of the FDA-approved medicines Dr. Wood weighs; another may suit you better, or none at all.
- Never alone. Medication sits inside a plan with a written nutrition plan, monthly visits and progress labs every 8 to 12 weeks.
What to expect from the result
The aim is health first. Losing 5% to 10% of your starting weight may lower blood sugar, blood pressure and triglycerides (NIDDK), and that is why progress is measured in labs and a body composition scan as well as on the scale. To find out whether a GLP-1 fits you, start with a new-patient visit for medical weight management.
