Can you life off of drinking protein shakes alone?

Even slim fast don't recommend it. You're supposed to have 2 shakes and a meal. Technically you could though, just as people can survive on eating junkfood every day - wouldn't be any worse for you. Just make sure you're getting enough calories, they are quite low.

Soylent is for people that want to eat only that. I don't see why anyone would want to, but it would be more healthy than other options as it's meant to be a complete diet.

Why not just put a tube through your abdomen and pump it it? I did that to my cat once and it worked really well!

Then you won't even have to brush your teeth after every 'meal'

Add in EFAs and cover micronutrient needs via supplementation and you could do it indefinitely. That doesn't make it a good idea, but it's biologically doable. You would just need to eventually get to a point where you consume enough to meet maintenance calorie needs, or you slowly starve to death.

I'm not as worried about the negative effects of a liquid only diet if its for a short time. people have tried more extreme measures than that. take a multivitamin in addition to the shakes and chew gum. remember that not eating anything will probably lead to rebound once your back on food. so be careful. take pics everyday so you can see if its working. good luck and be safe.

I did a 21-day liquid-only fast through my church, kind of like lent. I was very lenient in that I allowed myself to have anything that I was able to make into a liquid form. This included many protein shakes, slim fast meal replacements, as well as bananas and Greek yogurt blended into other smoothies. Once my 21-day fast ended, I had to relearn how to eat calories because I went overboard when I was able to eat food again and gained back 5lbs in 3 days (I lost 11.2lbs in 21 days). Just be careful when you decide to introduce food back into your diet more, that you don't go overboard because you will gain all of the weight that you lost, right back. Also I was working out while I was fasting, and I did notice that I had gotten very weak very quickly, and I noticed in my macronutrients that I was lacking iron, potassium, and sodium because of the fast. I immediately had soup broth to combat that effect and felt much better. So make sure that you have enough of all of the nutrients that your body needs, or you will not feel very well. It took about 10 days before I felt the effects of low sodium, low potassium, and low iron. This method works for a kick start to weight loss, but not for long term. I'm now logging food and exercise, and losing weight slower, but it's something I can maintain long term (this is my second go at MFP, where I previously lost 42lbs). I have learned how to balance my calories from drinks vs food, in order to be healthy and get to a healthier weight.

Come back in another four weeks and give us an update on how it's going, @NicholeWrightHR.

It sounds completely miserable to me...
