I caught this article on Google News: Is Carb Flu Really A Thing?

The premise was simple: Carb Flu was your body’s reaction to being improperly deprived of an essential macronutrient. Not – your body adapting to eating Low Carb.

Carb flu is legitimately your body’s way of telling you that it’s not able to process enough energy to function properly, says Amanda Kruse, RD, CD. “In some cases, your body may even go into survival mode as a way of conserving energy stores, because it’s not sure when you will feed it next,” Kruse says. “The grogginess and associated feelings are your body’s way of slowing you down to conserve energy.”

If you have carb flu, don’t just decide to ride it out, because you don’t have to avoid carbs or experience carb flu in order to be healthier. Carbs are probably the one thing that will make you feel better — so raise a croissant to that.


I beg to differ. You are going through Withdrawal – simple as that – withdrawal from an addiction to carbs – to sweets.

Adam Drewnowski took a fresh approach in examining the problem of bingeing, or compulsive overeating. Drewnowski knew there were links between sugar and addiction to opiates; studies showed, for instance, that sweets sometimes eased the pain of withdrawal.

So he treated his subjects as if they were drug addicts. He gave them a drug that counters the effect of opiates; called naloxone, this drug is given to people who overdose. Drewnowski then offered his subjects a variety of snacks— ranging from popcorn, which was low in sugar, to chocolate chip cookies, which were loaded with sugar, as well as fat. His findings: The drug worked best in curbing the appeal of the snacks that were highest in both.

The author’s suggestion that you should “raise a croissant to that” is equivalent of saying – if you are withdrawing from heroin – just get another shot to relieve your pain.
