Books ?? Good bad or indifferent

I purchased the following books:
Eat it up! The complete mind/body/spirit guide to a full life after weight loss surgery by Connie Stapleton PhD

I found it helpful and was wondering what others thought about it and if it stands true for after (post) surgery life.

Also Savor: Mindful Eating, Mindful Life by
Thick Nhat Hanh and Dr Lilian Cheung

Same question on this one ….
