Interesting paper in the most recent International Journal of Obesity.
They compared people's food intake giving them similar foods in liquid and solid form. When given the food in liquid form, people tended to consume about 15% more calories. (And 15% is a lot).
They tested different kinds of foods: high fat, high protein, and high carb. And they tested both lean and obese people. In all cases the result held up. If you need to lose weight, beware of taking food in liquid form. (Slimfast anyone?)
