The Keto Diet - What Our Health Experts Have to Say About the Diet Trend

So you want to lose weight fast. Is the keto diet a valid approach, or just another fad?

As a very strict and low carb diet, the ketogenic diet caught on because it sounds simple and can produce results.

But it can also be hard to maintain and should be undertaken with close monitoring by a health care professional with experience supervising the ketogenic diet.

The science behind this weight-loss diet is still being understood. In fact, more is being learned about its long-term effects.

A Little History on the Keto Diet

The ketogenic diet was created by Gianfranco Cappello, a surgery professor in Italy. His study included 19,000 dieters who experienced significant, rapid weight loss and few side effects.  The diet was also found to help control seizures in children with epilepsy, though it’s not yet understood why. This and other low-carb diets have shown promise for those with obesity, type 2 diabetes and cardiovascular risk factors.
The trick with keto is that it’s strict. You have to adhere closely to the diet or it won’t work.

How the Keto Diet Works

Put simply, a "keto" diet is an extremely low-carbohydrate, adequate protein and high-fat diet which forces the body into a state of ketosis. This occurs when a lack of carbohydrates lowers a body’s blood sugar levels, which causes the body to break down fat instead of carbohydrates to use as energy.

That breakdown of fat is where the weight loss occurs.

The Keto Diet Composition

The keto diet provides 80 to 90% of the energy from fat in a ratio of grams of (fat) to grams of (protein plus carbohydrate) as "4:1".1  The total amount of calories to be consumed should be based on an individual’s body mass index, prior dietary intake and physical activity.  Getting the 80 to 90% of calories from fat required to achieve ketosis can be difficult. It’s also very easy to go over on your carbohydrate limit. Others struggle getting enough, but not too much, protein. Without getting the right balance, you can be ingesting a lot of fat without achieving the weight loss.

Precautions

The ketogenic diet relies on ketosis, which generates a higher than usual level of ketones in your body.  This can be very dangerous for individuals with certain inborn errors of metabolism.  This is why health care providers urge keto dieters to be under the supervision of medical professionals including a dietitian or nutritionist.

Since the keto diet can be heavy on red meat and fatty foods, it’s not considered good for your overall, long-term health. Side effects which can occur over time include kidney stones, high cholesterol levels, constipation, muscle loss, slowed growth and bone fractures.

My Advice

If you want to go the keto route, work closely with your health care provider. If not, skip the keto route and stick with the basics. A healthy diet and regular exercise will achieve the weight loss you want.
