Delighted to contribute to the latest Financial Times feature on the growing consumerisation of GLP-1 therapies and the future of obesity treatment. It is important to remember that they remain medical interventions requiring appropriate clinical oversight, support, and equitable access.

Nipping at the heels of GLP-1 weight-loss drugs is the growing concern the pounds shed will be rapidly regained. "You don't want to have longer-term unintended consequences, like frailty and muscle loss. We don't want to replace one health concern with another." Read – buff.ly/OTpSvPq

@imsepidemiology.bsky.social’s @drmariespreckley.bsky.social is quoted in a BBC Future’s article, highlighting concerns that a lack of behavioural and lifestyle support for those on weight-loss drugs can lead to further issues. Read the full BBC Future – buff.ly/OTpSvPq

Fantastic to see this new study published in JMIR, led by our PhD student Hao Teng. In this qualitative study, we explored how young adults interact with food and nutrition content on social media, and how this can inform the design of effective interventions. www.jmir.org/2026/1/e89344

Delighted to contribute to this BBC Future piece out today. Ensuring the right support is in place to optimise outcomes is critical, particularly as use increases. www.bbc.co.uk/future/artic... @bbcstudios.bsky.social @imsepidemiology.bsky.social

Wonderful evening presenting on the impact of the cost of living crisis on infant feeding in the first 1,000 days of life. It has been an absolute privilege to work on this important study led by the brilliant @cararuggiero.bsky.social over the past two years. @imsepidemiology.bsky.social

What are the impacts of food insecurity during the first 1,000 days of life? Join @cararuggiero.bsky.social & @drmariespreckley.bsky.social this Thursday at 6 PM for a free in-person Cambridge Festival talk on insights from the SPROUT study. Register buff.ly/SRMHqfN

GLP-1 therapies work, but how do we balance clinical effectiveness with lived experience, equity, and long-term support? Looking forward to discussing this as a keynote panel member at the Society of Behavioral Medicine Annual Meeting in Chicago on 25 April this year. See you there!

Researchers from the University of Cambridge, University College London, and the University of Southampton comment on the necessity of keeping nutrition at the heart of management medications for children and adolescents.

Paediatricians in the UK are prescribing obesity management medications e.g. GLP-1s to children and adolescents for whom lifestyle interventions by themselves are not enough. Find out more in our blog - buff.ly/LS68rwH

Dr Spreckley @drmariespreckley.bsky.social leads the AMPLIFY study that seeks to understand how people experience next-generation weight loss therapies, to help identify the types of information and wrap-around support that are most meaningful and needed in real-world care. buff.ly/835YqxD (4/4)

Just 12 studies examined nutrition & diet alongside drug treatment, and as trials varied widely in their approaches to dietary advice and nutritional assessment, lacking standardised protocols and reporting, it was difficult to reach robust conclusions to inform the optimal support. (3/4)

In a systematic review published today, Dr Marie Spreckley, Dr Cara Ruggiero, and Dr Adrian Brown found a lack of robust evidence surrounding nutritional advice and support and its impact on calorie intake, body composition, protein adequacy, and patient experiences. buff.ly/Az65PyP (2/4)

New @cam.ac.uk and @ucl.ac.uk research finds people prescribed weight loss drugs such as semaglutide and tirzepatid may not receive sufficient nutritional guidance to support safe and sustainable weight loss, leaving them vulnerable to nutritional deficiencies and muscle loss. 🧵 (1/4)

Delighted to share that our latest study examining nutritional considerations when using next-generation obesity weight management medications such as Ozempic and Mounjaro is now published in Obesity Reviews. @cararuggiero.bsky.social @adrianbrown.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Dr Marie Spreckley @cam.ac.uk leads the AMPLIFY study, exploring the lived experiences of people using, or who have recently stopped, incretin-based weight loss therapies, to better understand how to support them with information and wrap-around support. Find out more at buff.ly/AxR0QqR (2/2)

"A key strength [of the guidance] is the emphasis on combining medication with behavioural support and on the need for equitable access, rather than presenting drugs as a stand-alone solution." @drmariespreckley.bsky.social comments on new WHO guidance on weight loss drugs. buff.ly/BEypph6 (1/2)

Environmental impact and cost to the consumer of meat, milk, and meat and milk alternatives. Much lower impact of all meat and milk alternatives. Unprocessed plant-based options best for both environmental impact and cost. Paper in PNAS by Marco Springmann (link in next post).
