Target Audience
This book should not be used as a guide for children to lose weight. Children have special needs as they grow and as their bodies’ change. If you have an overweight or obese child the person to look to for advice is your pediatrician.
This book is not appropriate for people who are ill. The first priority is to address the illness, and medical professionals should direct the treatment.
The target audience for this book is healthy adults who are overweight or obese, or slim adults who want to stay that way.
Author
The author of this book has no professional credentials in any of the subjects he writes about. It is always good to verify others’ assertions but doubly so in this case. To help with this, the book contains references to source material.
Authoritative Sources
Most of the source material is available on the Internet, but websites come and go. Referencing them in a book can lead to frustration if they are taken down later. There are two sites that contain quality information with links that are stable:
PubMed is a repository of abstracts on the functioning of healthy people and those with medical issues. Links to these abstracts will be in the form of PMID 10075319.
PubMed Central is a repository of full length free articles. Links to these articles are shown as PMC 3227989.
For more on PubMed abstracts and essays, see the “Read and Learn” section of chapter 2.
Products
Throughout the book various products are discussed. The author has used these and found them to be satisfactory. Better products may be available.
The author has no connection with any of the companies making the products, nor does he receive any payment for mentioning them.
Pronunciation
Saying “ess double you ell ell” is cumbersome. It is suggested that SWLL should be pronounced “swell”. It can then be used in conversation, e.g, “I’m on the swell,” or “I’m a swell guy.” Detractors of the SWLL will doubtless find a different pronunciation.
