Common short-term side effects include fatigue, headache, brain fog and upset stomach, aka “keto flu.” Long-term health risks include kidney stones, osteoporosis and liver disease.
Likewise, people ask, why is keto not good long term?
More Fat, Less Protein
In addition to breaking down fat cells, your body also breaks down muscle in the form of protein to create glucose. As a long-term side effect, this means that the keto diet eventually decreases lean body mass, which can make it harder to lose weight once the diet has ended.
Correspondingly, is keto diet healthy for everyone?
Keto Isn’t a Good Fit For Everyone. The keto diet is largely regarded as safe in both children and adults. However, the keto diet is probably still not a good choice for some, especially those with specific medical conditions.
Why is keto high fat?
On the keto diet, you eat so few carbohydrates that your body can’t rely on glucose for energy. And since keto meals are loaded with fat, your body switches over to using fat for energy instead of carbohydrates.
While some people have success staying on keto for an extended period of time, “the long-term research is limited,” says Jill Keene, RDN, in White Plains, New York. Keene recommends staying on keto for six months max before reintroducing more carbs to your diet.
Ketosis Isn’t Forever.
Then you’ll want to take an occasional ketosis holiday, adding a serving of unprocessed, whole grains to allow your body to chance to work less hard. Staying in ketosis long-term—without breaks— can cause muscle aches, nausea, and fatigue.
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 ketogenic diet is indeed a suitable lifestyle choice for those seeking either weight-loss, weight maintenance as well as improved and maintained overall metabolic health. Unfortunately, people deviate frequently through a lack of planning or a lack of support from friends and family.
The keto diet could cause low blood pressure, kidney stones, constipation, nutrient deficiencies and an increased risk of heart disease. Strict diets like keto could also cause social isolation or disordered eating. Keto is not safe for those with any conditions involving their pancreas, liver, thyroid or gallbladder.
The keto diet has been popularized in best-selling books, promoted by celebrities and touted on social media as an antidote to various ailments. Proponents say it causes substantial weight loss and can help those with Type 2 diabetes dramatically improve their blood sugar levels, which fall when people avoid carbs.
“As a cardiologist, I believe the keto diet is a mistake,” he said. “The keto diet, I believe, is based on misinformation.” According to Ostfeld, individuals following the keto diet miss out on eating whole grains, fruits, beans and other foods associated with significant health benefits.
