The second my never-tried-a-diet-in-his-life friend said he was doing keto (as mine recently did), I knew the eating plan had surpassed trend status.

What is the Keto Diet?

I’m going to go out on a limb and guess that, if said not-into-wellness-at-all friend has heard of (and is trying!) the keto diet, you most certainly have. Still, you may be a little hazy on the details. Well, no more!

Short for “ketogenic diet,” this eating plan is all about minimizing your carbs and upping your fats to get your body to use of fat as a form of energy, says Scott Keatley, registered dietician, of Keatley Medical Nutrition Therapy. While everyone’s body and needs are slightly different, that typically translates to: 60-75% of your kilojoules from fat, 15-30% of your kilojoules from protein, and 5-10% of your kilojoules from carbs.

After about two to seven days of following this eating routine, you go into something called ketosis, or the state your body enters when it doesn’t have enough carbs for your cells to use for energy. Then it starts making ketones, or organic compounds that your bod then uses in place of those missing carbs—and oh, it also burns fat for more energy, says Beth Warren, registered dietician, founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.

Why Did The Keto Diet Become So Trendy For Weight Loss?

Believe it or not, keto was designed to help people who suffer from seizure disorders—not to help people lose weight, says New York-based registed dietician Jessica Cording. That’s because both ketones and another chemical produced by the diet, called decanoic acid, may help minimise seizures.

But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it’s easy to go overboard on carbohydrates—but if you’re loading up on fat, it may help curb cravings since it keeps you satisfied.

That, plus the fact that ketosis encourages your body to burn fat, means you can end up with pretty dramatic weight loss.

“The keto diet took off because its ‘rules’ make sense to most people,” Keatley says. “Almost all of us want to lose some fat from somewhere on our body, and this diet focuses on fat as fuel.”

Celebs who’ve done the keto diet didn’t exactly hurt its rep, either. (We’re looking at you, Vanessa Hudgens and Halle Berry.)

What Can You Expect On The Keto Diet?

It usually takes three to four days for your body to go into ketosis because you have to use up your body’s stores of glucose, i.e., sugar first, Keatley says. Any major diet change can give you some, uh, issues, and Keatley says he often sees patients who complain of IBS-like symptoms and feel wiped out at the beginning of the diet. (The tiredness happens because you have less access to carbs, which give you quick energy, he explains.)

Those issues are part of what’s known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to the diarrhoea and tiredness. Luckily, the keto flu doesn’t usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.

Okay, But Will It Actually Help *You* Lose Weight?

Probably, and there are a few reasons why, Keatley says. For starters, people usually reduce their daily kilojoule intake to about 6,276 kilojoules a day because healthy fats and lean proteins make you feel fuller sooner—and for a longer period of time. And then there’s the fact that it takes more energy to process and burn fat and protein than carbs, so you’re burning slightly more kilojoules than you did before. Over time, this can lead to weight loss.

Everyone is different, and how much you weigh when you start the diet matters, but you could safely lose around one to two pounds a week on keto, Keatley says. “It’s sometimes more, sometimes less, depending on the individual’s caloric needs,” he adds.

Worth noting: The keto diet isn’t a “miracle fat burner,” says Keatley. “The kilojoules in the fat must are still kilojoules, so working out and keeping total intake at a reasonable level is the only way it works,” he says. “Being on a keto diet but eating more kilojoules than you need will still add fat to your frame.”

Who Does It Work Best For?
Cording says the keto diet is really ideal for people who suffer from seizure disorders. If that’s not you, she doesn’t recommend it as a long-term approach because it’s so hard to stick with.

That said, a keto diet will work for someone who really loves meat and heart-healthy oils like olive oil and safflower oil, Keatley says. However, he and Warren also stress that it’s not easy—or necessarily healthy—to follow over time (certain types of carbs are good for you!).

If you’re interested in following keto for a short period of time, Cording says it’s important to set yourself up for success by making sure you have the right ingredients and tools to make it happen.

Although if you just love carbs way too much to entertain the idea of doing the keto diet, well, that makes two of us.
