Living on protein shakes?

How can this be done. Really.

I see so often people crapping on about how normally they eat, then on a "What do you eat" type thread they list 3 protein shakes a day, and very little in the way of "real" food.

This disturbs me. Why are people so keen to deprive themselves of food. Is it that they think they will lose quicker if they don't eat?

There is one lady on the boards who HAS starved the weight off. Now that she only has 20lbs to get to her goal weight, she plans on losing that 20lbs in a month (a MONTH!!), and having an unfill.

That is just crazy. She is destined for massive regain.

Why? Because starvation only lasts for so long. Liquid diets only last for so long. People get sick of not eating. It takes a special type of will power to NOT eat for the rest of your life. And when they go back to eating "normally" (normal is usually over processed junk, no one learns about nutrition while starving themselves) they gain most, if not all of the weight back.

And people just don't seem to get that what they are doing NOW to lose the weight, is what they will have to do later to maintain the loss. I don't bother pointing this out on a regular basis, because I am unpopular as it is. But Damm. I would love to know how some of these people tick. What is the thought process behind starving yourself to malnutrition in the name of skinny.
