Avoiding food at night doesn't make a difference to weight gain.

I'm a smart cookie, but I also thought it was bad to eat late at night. Now I know better and can scarf muffins all night long! From the BBC:

Putting on pounds in the festive period almost seems inevitable but to avoid unwanted weight gain it has been suggested that people avoid eating late at night.

The idea is that you cannot burn off the calories if you are asleep. But this is not supported by the evidence.

A Swedish study found that obese women were more likely to eat at night, but they also ate more in general.

In another study of more than 2,500 patients, eating at night was not associated with weight gain but eating more than three meals a day was.

Ultimately, taking in more calories makes you gain weight whenever you eat them, the researchers said.

There are some other interesting debunked myths in the article. Who knew poinsettias weren't toxic?
