Juicing... Your thoughts!

How are you planning on getting enough protein, fats and fiber?

This would be my question as well.

To the person above who mentioned that vegans do it-- yes, vegans can get enough of these nutrients. However, they don't do it with juice only.

All juicing does is remove the fiber. The nutrients remain. The protein in the plants doesn't get left behind. There are plants with fat, too. Nuts, seeds, avocados, coconut, olives, etc. are full of fat. Though eating a low fat, low fiber diet for one week would have little effect on anyone. Eating nothing for one week would have little effect on anyone. When you're sick, the body often loses its appetite, to use that energy for recovery instead. We're adapted to store nutrients so we don't have to eat constantly. The body can also synthesize most nutrients within itself, from other amino acids.

This place is incredibly alarmist.

Right but it takes careful planning to make sure you're getting your body's requirements. Asking what the OP's plan is isn't being alarmist.

I was referring more to the claims that juicing for a week was dangerous. Though I do wonder how people who micromanage their macros and calorie levels think the species survived this long without that supposedly necessary careful planning, or how the animal kingdom does it. A very tiny fraction of beings track and yet the only malnutrition we see is in populations without easy access to a variety of foods.

Why not eat the whole fruit or veggie and get the fiber as well as all the nutrients?

My thoughts:

-you don't need to "detox" (I'm assuming you're not talking about detoxing from drugs or alcohol). Your liver, kidneys, lungs and skin do a great job of that already. It's east to be tempted by the idea, especially after a period of excess, like Christmas is for a lot of people. It really is just a gimmick though. Want to start eating better? Start eating better. Start adding more of the foods you want to add, and reducing the foods you want to reduce. It doesn't have to be so extreme.
-you get a lot of nutrients in juice, concentrated into a small volume - it's definitely easier to drink a few glasses of juice than to eat all the fruit that goes into it. However, you're cutting out a lot of the fibre, which is also good for you. If you have issues with blood sugar, you could have problems with only consuming sugary juice (even just the "natural" sugars from fruit) without the fibre that goes along with it.
-on a juice only diet, you're missing out on a lot of other essential nutrients (protein, fat, fibre). People seem to focus on all the micronutrients you get from juicing, and disregard the marconutrients your body needs.
-it's hard to stick with a diet that's a) so restrictive and b) is only liquids. For some people, that could cause problems with binge eating afterwards.
-thinking of eating as "cheating" is never a good idea.

So, basically, I think eating more fruit and vegetables is good. Supplementing your diet with fresh fruit juices is fine (assuming no issues with consuming a lot of sugar). Consuming only juice for a period of time is not only unnecessary, but could do more harm than good.
