Here's your "No, duh" for the day!

Echoing what dieticians have been saying for years, an Australian study shows that low-carb diets can be linked to grumpiness.

According to a study of 106 obese people, those following a diet that was low in fat and allowed some carbohydrates tended to be less angry, depressed and confused after a year than those on a high-fat, low-carbohydrate diet.

This study was published yesterday in the journal Archives of Internal Medicine. You can read more about it here.

I was surprised that the article I read didn't mention the fact that we need glucose for energy and that you get glucose from carbohydrates. If we don't have enough glucose in our system, our body starts to break down protein and fat for energy. That may sound like a good thing to those trying to lose weight, but some brain and nervous cells rely exclusively on glucose, so a shortage can make you feel mentally and physically sluggish. Of course you're going to feel cranky!

While it's worth noting that both diets were equally effective at reducing overall weight, wouldn't you rather, well, not be in a bad mood for a year?
