I agree in the sense that it might not be sustainable for someone to forever keep track of their calories. It's also challenging in the sense that while you could max out your daily calories from eating only cake, it wouldn't really give you enough nutrients to be sustainable. So I tend also to favor something that teaches people long lasting lifestyle changes and habits rewiring instead. This will be personal and different for everyone. Many lifestyle can work, and each can choose their own. But nothing is novel about this. The article hints at something novel, of the sort that if you changed your gut microbiome you might suddenly lose weight even if you keep eating the same way, because the body would metabolise differently. Or that each person has foods that make them fat, and if you identify what they are and cut them out, you can eat an infinite amount of the rest and you won't get fat. This would be really novel, but I failed to see proof of this in the article.
