You don't need doctor's degree to know the fact that such "diet" will lead to health problems in long term, but yeah -- sorry for unasked advice, it's not my business, let's just r8 as OP asked:
Looks nice, but hard to tell if the quality is any good. Coffee could be great, could be bad. The croissant is underbaked.
I used to have the same breakfast every day when riding the train to Uni so.. 7/8
