I wrote a couple of books in the last 3 or 4 years. They’re for sale on Amazon
‘One page fat loss’ is as it says. Everything you need to know to lose body fat in one page. Except that it takes a book to explain what each of the points are on the one page. Works for vegetarians as well as carnivores. It’s math based though, so if that freaks you out there should be enough in the learn menu link above to fix that.
The other book is about surfboard fin design.
