Founder · GLP-Done

Ian MacCallum is the founder of GLP-Done, the maintenance companion for people coming off GLP-1 medications. He built GLP-Done after watching the conversation around Ozempic, Wegovy, Zepbound, and Mounjaro fixate on getting on the drug, while almost nobody talked about the part that decides whether the results last: the off-ramp.

Every article here is researched from primary sources, peer-reviewed trials, NIH and PubMed Central, and guidance from bodies like the Cleveland Clinic and the FDA, and each claim links back to the study behind it. Where the evidence is mixed (fiber, alcohol, microdosing), the guides say so plainly rather than overselling.

GLP-Done is educational, not medical advice. Ian is not a physician, dietitian, or pharmacist, and nothing here should be used to start, stop, change, or taper a medication: those are decisions for you and your clinician. The aim is to explain the science of weight maintenance accurately, frame regain as physiology rather than failure, and give you an evidence-based system to hold the line.
