You should despair for it. It's mostly a religion somehow connected to pseudoscience, and definitely a far cry from science.

The two basic axiom that almost everything is founded on (weight diff = calories in - calories out; and prot=4Kc/g, carb=4Kc/g, fat=9Kc/g, alc=7Kc/g) are disproved every other day, in the sense that even though they do apply in many cases, there is at least one robust study in which they do not apply to every 4 in which they do apply.

Something fundamental is being totally ignored.

It's like saying "it is scientific that people go to work and school every day", and ignoring the existence of weekends.
