Just questioning. Like I said, I’m not totally sure from a practical standpoint how you’d hit 2,000 calories on whey protein, vegetables, Greek yogurt, and cottage cheese unless the yogurt and cottage cheese were the diet staples as opposed to secondary.
Not to pile on the questions, but why increase vegetable intake if you don’t want the fiber? Just for the phytonutrients? That’s not the worst idea, just a little odd. Without the fiber, you’re not going to get the same satiety, so that won’t be a big benefit.
Protein-sparing modified fasts (very low calorie, protein-focused diets) can definitely work, but they can be torturous and are usually very short-term, like the two-week window you’re looking at.
The juicing thing is worth a shot I guess. Or something like the V-Diet that’s 4 protein shakes and a solid meal a day, or a short-term carnivore diet, or a Green Faces approach.
The biggest thing is to not let it turn into a prototypical crash diet that reduces bodyweight and then rebounds right after. The macros during the diet will be one key there (keeping protein high), as will the transition off the diet (specifically, not jumping right back into a carb-dense plan).
