Ketogenic diet is work ，Why is it not recommended?

Ketogenic diet is work ，Why don’t nutritionists recommend it?

The years you have necessarily heard of ketogenesis, which seems to have become a trendy and personality style of life Is the ketogenic diet worth nothing to practice? What exactly does it mean for us?

1. What is a ketogenic diet?

The ketogenic diet (KD), retroactively derived, has been a matter of the last century, and it was first used in 1921 to treat epilepsy

There are also limitations to surgical treatment alone for epilepsy, particularly drug resistant epilepsy, (DRE), for which the ketogenic diet has long been adopted as a nonpharmacologic treatment option, with the implications of dietary treatment being significant particularly for some children unable to undergo surgical intervention

The last 1970s saw a burst of ketogenic weight loss upsurge in the United States 2018-2019 due to the flurry of low carbon diets fueled by the Atkins diet, which also brought the potential weight loss effects of ketogenic diets to the forefront, while also beginning to spread to other countries.

Although they all belong to a low-carbon diet, they have different restrictions on carbohydrates,

The classical ketogenic diet regimen for the treatment of epilepsy, with the most restrictive restriction of carbon water, is usually less than 50 g / D and more restrictive even less than 30 g / D (calculated according to the standard of 2000 kcal / D), while, at the same time, its fat proportion reaches the highest among all diet types, usually accounting for 80% to 90% of total energy, and therefore, the classical ketogenic diet is essentially used for the treatment of epilepsy.

Many of the ketogenic diets that are currently used by people to lose weight are adjusted and modified, not so high in fat, to about 70e80%, while increasing the carbon to water ratio, so the ketogenic heel for weight loss is not the same as ketogenesis for treatment.

For example, if an adult, who needs 2000 kcal per day, begins ketogenesis, then in his diet, there will be more than 1400 ~ 1600 kcal of energy derived from fat, that is, eat at least 155 ~ 178 g of fat per day, no more than 50 g of carbon water, and the remainder is protein.

There is no uniform standard of ketogenic diet for weight loss, but the rules are all similar:

2. The rationale for weight loss with ketogenic diets?

The amount of carbon ingested in ketogenic recipes is extremely low, but what does all the organs of our body need carbon water again for energy, and how can this be solved?

To maintain blood glucose homeostasis, glycogen stores in the body begin to dissipate, and for every 100 g of glycogen consumed, about 300 g of endogenous water is released and excreted in the process, which is the secret that the ketogenic diet before it allows you to lose weight quickly, and in fact, dehydration predominates.

What to do as you continue the ketogenic diet and the glycogen stores in your body are gradually depleted?

Generally after the maintenance of ketogenic diet for 4 ~ 7 days, the body begins to force fat burning, in the process of which ketone bodies are generated, enter the blood, and various organs of the body can use ketone bodies to replace glucose supply, at the same time, ketone bodies can cross the blood-brain barrier and enter the brain, transform into acetyl coenzyme A, and reenter the brain mitochondria to provide energy to the brain [3].

In addition, ketogenic processes can cause some degree of decreased appetite, etc

This is the rationale for weight loss with ketogenic diets. So Ketogenic diet is work

3. Weight loss effects of ketogenic diets?

Ketogenic diets do result in weight loss with favorable short-term effects, but also improve total cholesterol, glucose, and blood pressure. However, it still lacks large-scale and comprehensive studies to prove its safety.

Studies have shown that after a year, the effects conferred by ketogenic diets do not differ significantly from those of regular weight loss diets

In an analysis of 13 studies with a duration of more than one year, the investigators found that the additional reduction in weight from a ketogenic diet of no more than 1 kg, compared with a regimen of high carbohydrate, low fat, was of little clinical relevance

In addition, an analysis of 32 controlled feeding studies found greater energy expenditure and fat loss with a low-fat diet compared with a ketogenic diet

4. Side effects of ketogenic diet?

The process of ketogenesis is less benign and presents with a range of side effects including chronic fatigue, nausea, headache, alopecia, decreased alcohol tolerance, decreased physical performance, palpitations, leg cramps, dry mouth, poor taste, halitosis, gout or constipation.

These complications may be directly related to ketosis and its associated metabolic acidosis, which is further exacerbated by dehydration due to the ketogenic process, lack of fiber in the diet, increased uric acid, or loss of minerals.

Also because of the many drawbacks of this dietary pattern, the ketogenic diet ranked penultimate among a total of 39 diets on the USNEWS best diet leader board

Furthermore, it ranked 4th for the fastest weight loss diet, 15th for the best weight loss diet, 27th for the best diabetes diet, 34th for the best heart diet, 34th for the easiest to perform diet, and penultimate for a healthy diet. So, whether it’s weight loss or the perspective of treating the disease, ketogenic diet, really, not much… Although the rate of weight loss is fast, it’s also ranked 4th.

At this moment, we do not speak to how long you can adhere to ketogenesis and successfully resist the desire for carbon water in the face of these side effects alone

You need to think about one——

If a ketogenic diet is adopted to lose weight, do the benefits it provide outweigh the side effects it causes?

Especially when you need to maintain your weight through a long-term ketogenic diet, you may face some health risks, such as ketoacidosis, kidney stones, osteoporosis, high uric acid, and so on, and even life span may be reduced.

While maintaining the ratio of carbon water to around 55% recommended by dietary guidelines is sushi safe.

So, ketogenic weight loss has a clear short-term effect, but different side effects emerge, and there is no particular advantage to follow with other weight-loss diets, with unknown safety for long-term use.

This is also the most important reason why professionals temporarily do not recommend ketogenic diets for weight loss.Although Ketogenic diet is work .
