The low-carb craze is going strong. Bread is out. Pasta is overrated. And dieters are experimenting with how low their carb intake can go. But grains are anything but all the same.

So whether you are cutting out refined grains, whole grains or carbs in general, the effects can vary widely. Here’s a look at the wide array of things that could happen when you ditch carbs completely.

You Lose Water Weight

When you reduce your carb intake, the first thing you notice is how quickly, even magically, the weight falls off. But it’s not fat you’re losing. It’s water. “When carbs are stored in the body in the form of glycogen, each gram of carbohydrate stores three to four times its weight in water,” says dietitian and strength coach Marie Spano. So as soon as you cut carbs and start using your glycogen stores, you’ll lose a good amount of water weight.

You Catch The ‘Low-Carb Flu’

“Carbs are the brain’s main source of energy,” says Spano. “When a person cuts down on carbs, the brain is running on fumes, especially as glycogen stores get low and become depleted.” Eventually, once all that glycogen is gone, your body breaks down fat and runs off of little carbon fragments called ketones. The result: bad breath, dry mouth, tiredness, weakness, dizziness, insomnia, nausea and brain fog. Basically, you feel like you have the flu. However, your body eventually adapts to running on ketones so you don’t feel so bad, but they are still aren’t your body’s preferred fuel source, says Spano.

Your Cravings Subside

Refined carbohydrates like white bread, are infamous for sending your blood-sugar levels through the roof, only for them to crash back down again. And recent research published in the American Journal of Clinical Nutrition suggests that the rollercoaster ride could activate addiction centres in the brain, leading to subsequent cravings. Opting for fibre-rich whole grains, like brown rice, quinoa or barley, can keep blood-sugar levels from plummeting to prevent cravings, says nutritionist Alex Caspero.

Your Risk Of Heart Disease And Diabetes Goes Up Or Down

The type of grains you cut could make a big difference here. For instance, a 2014 study published in PLOS ONE found that refined carbohydrates drive up the body’s levels of a fatty acid (called palmitoleic acid) to raise the risk of heart disease and type 2 diabetes. Meanwhile, according to the American Heart Association, whole grains can improve blood-cholesterol levels and lower risk of heart disease, stroke, obesity, and type 2 diabetes.

Your Energy Levels Drop

Whole grains are a great source of iron, magnesium and B vitamins, all of which are critical in maintaining energy levels, says Spano, who notes that many people are already deficient in magnesium. Plus, since carbs are your body’s preferred fuel source, all of your cells slow down without a healthy supply, says Caspero.

You Don’t Poop

Whole-grain intake is a major player in how much fibre you get, according to a recent Nutrition Research study that found that 92 percent of US adults don’t get enough of the grains. Fibre, the indigestible part of plants, like grains, not only helps stabilise blood-sugar levels, reduce the risk of obesity, and chronic diseases, but also prevents you from being constipated, says Spano.

You Get Really Moody

And not just because you’re eating all of your sandwiches as lettuce wraps. Carbs – whether they are whole or refined – increase the brain’s levels of the feel-good neurotransmitter serotonin, says Caspero. So when you cut healthy carbs like whole grains, your mental health goes right along with it.

Your Workouts Suffer

“Carbohydrates are the body’s primary source of energy for fuelling all exercise, including both endurance and resistance training,” says Spano. “Cut carbs, and your energy will drop. Decrease your levels of your body’s stored carbohydrates, and your ability to produce force and power will decrease.”
