Welcome,
My favorite for the Ultimate guide to a Low Carb Diet for Beginners, including a one page folder that summarizes the food lists to help you shop. https://www.dietdoctor.com/low-carb
You do not have to join the site, tons of information and recipes are free, but there is an optimal membership that provides many more films, video talks, interviews with experts, and that is Free for one month, easy to cancel.

Check the Research/Media section here for recent news about LC in the UK, low carb health care workers speaking before Parliment, etc. including the NHS approving a LC programme for diabetes. Things are changing. http://forum.lowcarber.org/forumdisplay.php?f=4

Highly recommend the PHC organization, their list of RCTs on LC is the most complete, can also find LC healthcare providers if you need more advice. https://phcuk.org

All the best,
