Stop a GLP-1 and about two thirds of the weight loss comes back within a year. Three randomized withdrawal trials (SURMOUNT-4, STEP 1 extension, STEP 4) and a new BMJ 2026 systematic review of 37 RCTs and nearly 10,000 adults all land on the same signal. The cardiometabolic benefits, blood pressure, fasting glucose, lipids, drift back in parallel with the weight. The framing that actually fits the data: GLP-1s behave like a statin. There is a cumulative benefit during exposure, but this does not extend indefinitely,
This month's Direct Line covers two subscriber questions. The first asks what the new BMJ paper on GLP-1 cardiovascular protection after cessation actually shows, and how GLP-1 durability compares to lifestyle-only interventions. The second asks how a postmenopausal woman newly diagnosed with osteopenia should structure her lifting.
Studies referenced: SURMOUNT-4 (Jastreboff, JAMA 2024), STEP 1 extension (Wilding, Diabetes Obes Metab 2022), STEP 4 (Rubino, JAMA 2021), West et al. BMJ 2026 systematic review, Budini 2026 eClinicalMedicine regain meta-analysis, SELECT cardiovascular outcomes, FLOW renal outcomes, the Diabetes Prevention Program, Look AHEAD, POUNDS Lost, and LIFTMOR (Watson, JBMR 2018).
