Hello, mo. Pasta is a complex carbohydrate, giving you 4 calories a gram. The word "complex" means that it's not a simple sugar. These types take longer to digest and are more filling than vegetables. That's part of the reason why one feels hungry shortly after eating at a Chinese restaurant, assuming you're loading up on veggies. Protein is more filling than carbohydrates are, probably due to the extra work the body does in breaking the protein down. Proteins also supply 4 calories a gram. Protein is usually found combined with fat - as in meat. Fat provides the greatest amount of satiety. So clearly meat is the winner over pasta or veggies, because it contains lots of protein and fat. That's why that "hot off the bone rib steak" is so filling. Fat also provides you with the most calories, at 9 calories per gram. Hope that helps, Peter Bosani. For more info - go online to: www.madsci.org and type in "Why do some foods make you more full than others?", which I recently answered.
