Here's some interesting news from a study conducted at Purdue University: eating liquid foods might make you eat more calories during the day, because our bodies register the calories a lot slower.
The tests were done on 120 men and women. On day one they were given a test lunch of a chicken sandwich and water, and were allowed to eat any meal they wanted later in the day. On the other days, a liquid or solid food was given along with the chicken sandwich (milk or cheese, coconut or coconut milk, and watermelon or watermelon juice). They could have as many sandwiches as they wanted after eating the samples and then recorded how full they were. This is all confusing to me, but I wonder if this is one of the reasons why people on liquid diets and diets that have liquid meal replacement options often gain weight later.
Though I wonder how accurate it is, since it was only a three day study. I'd like something with a little more depth, but it's an interesting start.

Actually, the vast majority of people who go on any kind of diet gain the weight they lose back. I've heard about other studies showing that people will ingest more calories over the course of a day if they're consuming liquids with calories, but there are plenty of reasons diets in the long run just don't work.

i've heard that you shouldn't drink your calories. i think i guessed that the liquid ones were not as satisfying, or that it was just healthier to drink water. i do know a guy who lost a lot of weight just because he stopped drinking soda.

Eat whole foods. If there's nothing left but liquid it's just heart-mangling calories that will cause the liver and gall bladder to produce more cholesterol.
Hush, child and eat your beans and corn!

The researchers lost all credibility at the end of the article, when one of them claimed that bodies don't process liquid calories accurately because, until very recently in human history, the only available beverage was water.
So nobody milked a cow or a goat?
Nobody squeezed a juicy piece of fruit?
No one stomped grapes for wine, brewed beer, or distilled spirits?
Given that there's evidence for dairy herds in 7000 B.C. and wine-making in 5000 B.C., I don't quite buy the "our bodies can't handle drinks with calories" argument.

My bosses wife forces him to down Slim-fast for two meals a day. More often than not, I find them laying on his desk while he sadly scavenges through the shop kitchen. I occasionally buy an extra sandwhich and what-have-you from Subway when I can afford it, and he downs them like a concentration camp victim. Liquid calories=crap. It's better for the body to actually digest food, and you actually use up more calories processing harder foods.

The scientists quoted at the end of the article were not involved in the study.

I agree with the above. Plus, liquid food makes you feel entitled for something more. You don't feel as guilty I guess.

I think it depends on what kind of liquid you're drinking. When I drink a soy milk smoothie for breakfast-- basically a liquid protein with lots of sweeet fruit, it carries me through until lunchtime. But who wants liquid meals, anyway? Life's too short.

I'm not sure a three-day study means much on its own--but this adds to other research suggesting that high-calorie liquids may contribute more than solid foods do to weight gain. It's one of the reasons researchers are looking at soft drink consumption as a major suspect in the epidemic of childhood obesity. Nothing like drinking pop by the bucket...
