What are GLP-1 medicines?
GLP-1 receptor agonists are a class of medicine originally developed for type 2 diabetes that are now widely used for weight management. They work by mimicking a natural hormone that regulates appetite and blood sugar.
Why this matters
GLP-1 medicines have changed the landscape of weight management. But understanding what they do — and what they don't do — is important for anyone using them or considering them. The early months often feel straightforward, but long-term maintenance is where the real challenge begins.
How GLP-1 medicines work
GLP-1 receptor agonists mimic the effects of a naturally occurring gut hormone called glucagon-like peptide-1. They work through several mechanisms:
- Appetite reduction: They act on brain receptors that regulate hunger and satiety, reducing appetite and helping people eat less
- Slower gastric emptying: Food moves through the stomach more slowly, contributing to feelings of fullness
- Blood sugar regulation: They stimulate insulin release in response to food and reduce glucagon secretion, helping manage blood sugar levels
Common GLP-1 medicines in the UK
Several GLP-1 receptor agonists are prescribed in the UK for weight management and/or type 2 diabetes. These include semaglutide (branded as Wegovy for weight management and Ozempic for diabetes), tirzepatide (Mounjaro), and liraglutide (Saxenda). Your prescriber will recommend the most appropriate option for your circumstances.
Why maintenance matters
GLP-1 medicines can be very effective for weight loss, but the benefits depend on continued use and consistency. Research shows that stopping treatment is often followed by weight regain. The maintenance phase — staying consistent over months and years — is where support matters most.
Understanding what to expect, recognising early signs of drift, and having a low-burden support system can make a meaningful difference in long-term outcomes.
How Healthcount helps
Healthcount is quiet-by-design. It's a sat-nav for GLP-1 maintenance: it stays quiet when things look stable, and it nudges you when signals suggest drift. It uses low-burden signals and doesn't require daily food logging or extensive tracking.
Healthcount does not prescribe, diagnose, or advise dose changes. It supports maintenance and signposts you to clinical support when needed.
