A North Western University study has found that eating at irregular times -- the equivalent of the middle of the night for humans, when the body wants to sleep -- influences weight gain.

The regulation of energy by the body's circadian rhythms may play an important role. The study is the first causal evidence linking meal timing and increased weight gain.

The American Institute for Cancer Research in Washington, D.C. provides valuable information about weight gain during pregnancy. They tell us that the far more common problem is gaining too much weight during pregnancy, which can lead to short- and long-term risks for both mother and baby.
