In the past, the ketogenic diet has shown a variety of benefits. It is a low-carb diet that contains a high amount of fat to promote the body's use of fat for energy.
One study, for example, linked it to Better brain healthOne person suggested that it might be one. Early symptoms of Alzheimer's disease can be reducedThis has been associated with reduced blood pressure and blood sugar levels.
Not everything is perfect in the ketogenic world. According to a new study published in the journal Cell Reports Medicine, following a ketogenic diet can be harmful to your gut bacteria. It can reduce "good bacteria," increase cholesterol, and decrease glucose tolerance.
Discover the benefits of a ketogenic diet
Study participants were randomly assigned to one of three diets: a moderate-sugar diet (control group), a low-sugar diet (less than 5 calories from sugar), or a ketogenic diet (less than 8 calories from carbohydrates). This study hypothesized that restrictions on physical activity would be reduced. However, this was not true. However, they did change their body composition.
The ketogenic diet increased cholesterol, unlike a low-sugar diet, which significantly lowered cholesterol. The diet increased the amount of apolipoprotein B, which is responsible for plaque buildup in the arteries.
Aaron Hengist is the lead researcher and believes that the accumulation of "unfavorable" fats in the blood can increase heart attacks and strokes if they continue for years.
Bifidobacteria
Bifidobacterium is an important intestinal bacterium found everywhere. ProbioticsYou can also learn more about the following: Functional foodsThe benefits of this plant include the production of B vitamins, inhibition against pathogens, harmful bacteria and reduction of cholesterol.
The diet also reduces beneficial gut bacteria such as bifidobacteria, which are often found in supplements. Sugar restriction had no effect. This could lead to intestinal infections, digestive disorders such as IBS, or a weakened immune system, according to Dr. Russell G. Davies.
A ketogenic diet can also reduce glucose tolerance. This means your body is less efficient at handling carbohydrates. Professor Javier Gonzalez, who led the study, said that while low glucose tolerance isn't harmful for people following the ketogenic diet, it could be harmful for people who return to eating a lot of carbohydrates.
The ketogenic diet was found to be more effective in some ways than the low-glycemic diet. The low-glycemic diet only resulted in a 2.1 kg fat loss over 12 weeks, while the ketogenic diet resulted in a 2.9 kg weight loss.
Ketones, ketosis and the ketogenic diet
When the liver breaks down fat, it produces ketones. The body then uses these chemicals for energy when exercising, fasting, or without access to carbohydrates. The ketogenic diet produces ketones. The ketogenic diet induces ketosis. This is the process by which your body converts stored fat into energy.
The researchers concluded that for the majority of people, a low-sugar diet is preferable to the riskier ketogenic diet.
This study, funded by Rank Prize Funds and involving Ian Tarr of the University of Bath and the Cosun Nutrition Center (the nutrition arm of the Dutch agricultural cooperative Cosun), was conducted with input from Ian Tarr.
What effect does keto have on the good bacteria in your gut?
Russell G. Davies claims that the decline in bifidobacteria is due to a reduction in fiber intake. This amounts to about 15g per day. This is half the UK's recommended daily intake. He stated that bifidobacteria need fiber to survive.
What is the effect of keto on cholesterol?
It is common to find bifidobacteria linked to lower cholesterol levels. According to this study, the decrease in bifidobacteria could lead to an increase in cholesterol levels.
Ketosis and a high-fat diet could be responsible for the increase in cholesterol. Javier Gonzalez, a spokesperson for FoodNavigator, said that we know that both of these factors increase cholesterol-containing lipoproteins.
This is thought to be a result of reduced clearance of lipoproteins by the liver, but it could also occur due to increased production of lipoproteins.
What is the effect of the ketogenic diet on glucose tolerance?
The study found that the ketogenic diet reduces glucose tolerance.
Javier Gonzalez believes that reduced glucose tolerance in people on a ketogenic diet is an adaptive response to eating fewer carbohydrates.
