Great books and recipes in my opinion. The Facebook group is good as well. Not endorsed by any of the slimming companies but are easily compatible with them.
When I lost weight in 2016/17 I loved the recipes from PON. I recently got book 3 which people are loving. (£10 Amazon etc). Now to find motivation again!
Good luck. Happy New Year as well, hope it’s a better one!
