Felt Rider is right on target. Skipping meals is not a good idea. In Dan Bernadot's book Advanced Sports Nutrition he cites a very interesting study. Two groups of athletes were put on different dietary regimes. The groups were isocaloric, or IOW given the same number of calories per day and both burned the same number of calories in training. One group ate 3 big meals per day, the other ate many smaller meals throughout the day. Again, the total calories were the same.
Sure enough both groups lost the same amount of weight by the end of the study. So calories in vs. calories out didn't change. The interesting thing is that the 3 meal per day group ended up with higher body fat and lower lean body mass. The small meal group ended up with lower body fat and higher lean body mass.
The interpretation is that 3 large meals per day puts the body through mini boom-bust cycles or mini starvations followed by mini binges. The body catabolizes muscle to fuel itself during the mini starvations and then stores excess calories as fat during the mini binges. The group with smaller steadier eating avoided the peaks and valleys in blood sugar and didn't consume as much of their precious muscles nor have to store excess calories as fat.
It's just one study, but a very interesting one as far as athletes and eating patterns is concerned.
