It's basic CICO, from having skimmed it. The problem is this type of diet has the greatest likelihood of failing. CICO is hard to maintain. Eventually willpower fails and gradual overeating begins, leading to surprisingly large and abrupt weight regain. Being persistently hungry all the time just sucks.
Some of the stuff is possibly wrong, like this
There's a lot of nonsense floating around regarding exercise and weight control. The only way to lose weight is to eat less than your body burns. Period. Exercising causes your body to burn more, but few people have the time or inclination to exercise enough to make a big difference. An hour of jogging is worth about one Cheese Whopper. Now, are you going to really spend an hour on the road every day just to burn off that extra burger?
There is scant to zero literature to suggest exercising raises metabolism. Recent research by Herman Pontzer shows the opposite, that calories burned with exercise are negated later through lowered BMR and NEAT. So if you do a 400-calorie run and then eat a 400 calorie cookie, you will still get a net 400 gain, or close to it.
