A Nutritionist's Honest Guide to GLP-1s, UPFs & How to Eat Well in the Modern World | Rob Hobson

takeaways

1. Rob Hobson explains that when eating less on GLP-1 medications, nutrient density matters because the body still needs protein, fibre, vitamins and minerals even when hunger drops.

2. The conversation covers how GLP-1 access is limited on the NHS (requiring a high BMI and comorbidities), and how people getting drugs online may lack dietitian support, leading to poor nutrition and issues like hair loss from low iron and protein.

3. Hobson argues the NOVA ultra-processed food classification is too blunt, pointing to foods like baked beans, hummus and cooking sauces that don't behave like typical UPFs and can be affordable, nutritious options.

4. On fibre, he notes UK intake is chronically low (well below 30g a day) and cautions against 'fibre maxing', recommending increasing intake slowly with plenty of water and aiming for 30 different plants a week.

5. He discusses the MTHFR gene variant and folic acid, saying it's a common variant that rarely has major impact and that folate is best obtained from food such as fruits and vegetables.

6. Hobson critiques black-and-white nutrition messaging on social media (including the carnivore diet and 'toxic seed oils' claims), stressing the value of nuance and properly qualified sources.
