Welcome to the hunger games.

We all have that friend who occasionally runs on a cool 700 calories a day for a week so they can ~lose weight fast~ or whatever.
And, OK, sometimes you are that friend.

That’s a crash diet. As in, it’s pretty much bound to crash and burn.
A crash diet is essentially a very restrictive meal plan that’s unsustainable for the long term, says Darcy Johannsen, Ph.D., R.D., assistant professor at Pennington Biomedical Research Center. It’s usually about severely restricting your calories — like cutting back to 1,000 or even as low as 500 calories per day. Or sometimes a crash diet is all about a juice cleanse or just eating one or two foods for a week. The length of time differs from diet to diet, but they always come with an end date.
Here’s the thing: Crash diets can actually wreak havoc on your body, not to mention your general disposition (because, hangry). Here are nine reasons you should probably never do them again:
Your metabolism slows WAY down, so you suck at burning calories.
“When you limit calories so dramatically, your body goes into starvation mode and your metabolic rate plummets,” says Johannsen. Your body isn’t sure when it’s going to get fed again, so it does everything it can to conserve energy. So not only are you burning fewer calories doing normal activities (like digesting, standing, walking), but you’re also just moving less because you have less energy.
