<\/a><\/figure>\n<\/div>\n\n\nWhat is GLP-1?<\/strong> <\/h2>\n\n\n\nGLP-1 (or glucagon-like peptide-1)\u202fis a hormone found in the body that helps regulate blood sugar and appetite.\u202fIt\u2019s made in the gut and released after we eat. <\/p>\n\n\n\n
How does GLP-1 work and what does it do in the body?<\/strong>\u00a0<\/h2>\n\n\n\nGLP-1 works by stimulating in the release of insulin in the body, a hormone that helps our cells use the sugar from our blood. It also slows down how quickly food leaves the stomach, meaning we feel fuller for longer, and sends signals to the brain indicating that we\u2019re full. This, in turn, reduces our appetite.\u00a0<\/p>\n\n\n\n
Why do I keep hearing about it?<\/strong> <\/h2>\n\n\n\nThe flurry of news stories about weight loss medications (including Wegovy and Mounjaro) may have something to do with it. These medications act by mimicking<\/em> GLP-1, causing increased feelings of fullness and reduced appetite, leading to weight loss for some people.<\/p>\n\n\n\n![\"get](\"https:\/\/www.slimmingworld.co.uk\/wp-content\/uploads\/2026\/02\/GetRealSupport-SmallCTA-2026_SlimmingWorldBlog.jpg\")
<\/a><\/figure>\n<\/div>\n\n\nWhich weight loss medications have an impact on GLP-1?<\/h2>\n\n\n\n
The GLP-1 medications licensed for weight loss in the UK (and their brand names) are semaglutide (Wegovy), tirzepatide (Mounjaro) and liraglutide (has various brands but mainly Saxenda). You may hear other names like Ozempic, which is licensed to treat diabetes, not for weight loss. <\/p>\n\n\n\n
Does natural GLP-1 have the same impact as the GLP-1 that is mimicked by the weight loss medications?<\/strong> <\/h2>\n\n\n\nNo, they have different effects. Natural GLP-1 is broken down quite quickly by an enzyme in the body that the weight loss drugs have been designed to withstand. The effects of natural GLP-1 are therefore more short-lived, mainly felt around mealtimes, whereas the weight loss medications can last days or weeks depending on which one is used and the dosage. Due to their prolonged presence, the weight loss drugs are more potent and have a stronger effect on appetite suppression than the GLP-1 that is naturally produced in the body. <\/p>\n\n\n\n
Do certain foods increase GLP-1 secretion?<\/strong> <\/h2>\n\n\n\nAll foods stimulate the release of GLP-1, but certain foods can increase it more than others. For example, foods high in protein such as chicken and eggs, dairy foods such as milk and yogurt, healthy fats such as avocado or olive oil and soluble fibre such as oats and lentils can all increase GLP-1 naturally. Although this natural GLP-1 is broken down relatively quickly, these foods also bring additional health benefits. They\u2019re all Free Foods or Healthy Extras that can be enjoyed as part of Slimming World\u2019s healthy eating plan<\/a>, Food Optimising.\u00a0<\/p>\n\n\n\n![\"diabetes](\"https:\/\/www.slimmingworld.co.uk\/wp-content\/uploads\/2025\/02\/Body-AirFryerChickenTikka-DiabetesUK_SlimmingWorldBlog.jpg\")

<\/a><\/figure>\n<\/div>\n\n\nSo, can I still feel full and lose weight without weight loss medications?<\/strong> <\/h2>\n\n\n\nAbsolutely! We conducted research which showed that people following our healthy eating plan felt fuller and less hungry and<\/em> lost more weight than people following a calorie-controlled plan. This is because Food Optimising is based on low energy-dense foods, meaning you can fill up for fewer calories. We also encourage a generous intake of filling foods high in fibre and protein. <\/p>\n\n\n\nWhen you join Slimming World<\/a>, you\u2019ll get all the information you need to follow Food Optimising \u2013 including a full list of Free Foods and Healthy Extras \u2013 in the new member book. You can also use the Food Search tool and barcode scanner on the app to easily see how different foods fit into the plan, as well as which foods are high in protein and fibre.\u00a0<\/p>\n\n\n\nFind out more about the science behind the Slimming World plan<\/a><\/strong> <\/p>\n\n\n\n![\"black](\"https:\/\/www.slimmingworld.co.uk\/wp-content\/uploads\/2025\/11\/Body-BlackEyeBeanSaladCavoloNero_SlimmingWorldBlog.jpg\")

Support to have a healthy diet and increase your physical activity is especially important if you\u2019re taking weight loss medications to ensure you\u2019re getting the essential nutrients you need, and for muscle maintenance (both are vital for good health). We have a suite of resources<\/a> created for members taking weight loss medications, including a booklet to provide tailored support and an online hub dedicated to delving deeper into the support required around weight loss medications with nutritional guidance, meal plan ideas and strength-based activity videos. Plus, Slimming World provides long-term support, which is especially key for weight loss maintenance in the long term once you stop taking the medication.\u00a0<\/p>\n\n\n\n
