Is the keto diet safe to use every day?
The "keto" diet is any extremely low- or no-carbohydrate diet that forces the body into a state of ketosis.
Ketosis occurs when people eat a low- or no-carb diet and molecules called ketones build up in their bloodstream.
Low carbohydrate levels cause blood sugar levels to drop and the body begins breaking down fat to use as energy.
Ketosis is actually a mild form of ketoacidosis. Ketoacidosis mostly affects people with type 1 diabetes. In fact, it is the leading cause of death of people with diabetes who are under 24 years old.
However, many experts say ketosis itself is not necessarily harmful.
Some studies, in fact, suggest that a ketogenic diet is safe for significantly overweight or obese people.
However, other clinical reviews point out that patients on low-carbohydrate diets regain some of their lost weight within a year.
The diet would not necessarily improve athletic performance, a fact that may discourage some athletes.
People need to adhere closely to the program or it will not work.
Rudy Mawer ,sports nutritionist , has also found some success with the keto type of diet.
"It is a very strict diet," said Mawer. "You have to do everything right."
Every individual, he notes, is different and will react differently to such a program.
"What's great for one person can be horrible for another person," he said.
Critics say the keto-type diets usually work only in the short term and can be unhealthy.
For starters, most of the lost weight is water weight, according to Lisa Cimperman, R.D.N., a clinical dietitian at University Hospitals Case Medical Center in Cleveland, Ohio, and a spokesperson for the Academy of Nutrition and Dietetics.
"Once your body enters ketosis, you also begin to lose muscle, become extremely fatigued, and eventually enter starvation mode. Then it actually becomes even harder to lose weight," Cimperman told Healthline.
Mawer said he doesn't believe the keto diet causes muscle loss. He did caution it's not optimal for someone trying to gain muscle.
Other experts interviewed by Healthline had stronger words of caution.
"Keto diets should only be used under clinical supervision and only for brief periods," Francine Blinten, R.D., a certified clinical nutritionist and public health consultant in Old Greenwich, Connecticut, told Healthline. "They have worked successfully on some cancer patients in conjunction with chemotherapy to shrink tumors and to reduce seizures among people suffering from epilepsy."
Cimperman (R.D.N , clinical dietitian at University Hospitals Case Medical Center in Cleveland , Ohio) aid the healthiest approach to weight loss is to set realistic goals and ask yourself if your diet plan is:
* good for the long term
* includes exercise
* meets your long-term health goals.
Exercise, of course, is also vitally important. Every pound of muscle equals 50 calories burned, so a plan that includes a muscle enhancing regimen will help you reach your goal faster.
