What Is It? What’s a Ketogenic Diet

The ketogenic diet (or keto diet, for short) is a low-carb, high-fat diet that offers many health benefits.

“Ketogenic” is a term for a low-carb diet (like the Atkins diet). The idea is for you to get more calories from protein and fat and less from carbohydrates. You cut back most on the carbs that are easy to digest, like sugar, soda, pastries, and white bread.

How It Works Ketogenic Diet

When you eat less than 50 grams of carbs a day, your body eventually runs out of fuel (blood sugar) it can use quickly. This typically takes 3 to 4 days. Then you’ll start to break down protein and fat for energy, which can make you lose weight. This is called ketosis. It’s important to note that the ketogenic diet is a short term diet that’s focussed on weight loss rather than the pursuit of health benefits.

Who Uses It?

People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.

Weight Loss

A ketogenic diet may help you lose more weight in the first 3 to 6 months than some other diets. This may be because it takes more calories to change fat into energy than it does to change carbs into energy. It’s also possible that a high-fat, high-protein diet satisfies you more, so you eat less, but that hasn’t been proved yet.

Cancer

Insulin is a hormone that lets your body use or store sugar as fuel. Ketogenic diets make you burn through this fuel quickly, so you don’t need to store it. This means your body needs — and makes — less insulin. Those lower levels may help protect you against some kinds of cancer or even slow the growth of cancer cells. More research is needed on this, though.

Exercise

A ketogenic diet may help endurance athletes — runners and cyclists, for example — when they train. Over time, it helps your muscle-to-fat ratio and raises the amount of oxygen your body is able to use when it’s working hard. But while it might help in training, it may not work as well as other diets for peak performance.

Side Effects

The more common ones aren’t usually serious: You might have constipation, mild low blood sugar, or indigestion. Much less often, low-carb diets can lead to kidney stones or high levels of acid in your body (acidosis). Other side effects can include the “keto flu,” which may include headache, weakness, and irritability; bad breath; and fatugue.

Diet With Care

When your body burns its stores of fat, it can be hard on your kidneys. And starting a ketogenic diet — or going back to a normal diet afterward — can be tricky if you’re obese because of other health issues you’re likely to have, like diabetes, a heart condition, or high blood pressure. If you have any of these conditions, make diet changes slowly and only with the guidance of your doctor.
