The Keto diet has managed to break out of its label as the latest trendy diet because of its proven rate of success with weight loss.
The report, which was published in the January Issue of Nature Metabolism, posits that over limited periods of time a high-fat low-carb diet can greatly reduce a follower’s risk of developing diabetes and inflammation but after one week these positive effects begin to diminish as a result of the very mechanisms that fostered them.
A metabolic threshold
The Keto diet works by forcing the body to use alternative sources for fuel via prolonged exercise and or starvation. More specifically, followers obtain 99% of their calories from fat and 1% from carbohydrates.
Once the body is tricked into thinking that it’s starving it will start burning fat instead of carbohydrates in order to preserve energy. Eventually, chemical byproducts called ketone bodies are produced. Ketone bodies serve as alternative energy sources for organisms during periods of glucose scarcity.
The immediate benefit of this process has to do with tissue-protective gamma delta T-cells. These begin to spread throughout the body as a direct result of ketosis.
“This reduces diabetes risk and inflammation, and improves the body’s metabolism,” explained Vishwa Deep Dixit, the Waldemar Von Zedtwitz Professor of Comparative Medicine and of Immunobiology. “After a week on the keto diet, mice show a reduction in blood sugar levels and inflammation.”
The problem is fat break down and fat storage began to happen at once, which means the rodents consumed more fat than they could possibly burn. Eventually, those essential gamma delta T-Cells diminished and the likelihood of the subjects developing metabolic disorders surged dramatically.
This new metabolic consequence joins a slew of previously established ones.
Many experts believe that limiting your carb intake to 1% over a long period of time makes it extremely difficult to include important sources for vitamins and minerals found in foods like fruits, beans/legumes, and whole intact grains. In addition to energy preservation, carbohydrates promote tissue synthesis, provide us with our recommended value of macro-nutrients and prevent the development of several kinds of chronic illnesses.
For individuals that need to lose quickly for whatever reasons, tweaking your metabolism to augment fuel sources seems to be the trick. Experts just urge followers to consults a nutritionist to determine how long and how rigidly they ought to restrict carb intake.
“Before such a diet can be prescribed, a large clinical trial in controlled conditions is necessary to understand the mechanism behind metabolic and immunological benefits or any potential harm to individuals who are overweight and pre-diabetic,” Dixit said in a press statement.
It’s important to note that more research needs to be done before a categorical threshold can be translated to human trials—even in consideration of the striking genetic similarities we share with mice. The most important citation motioned in the new study relates to the benefits and setbacks afforded by ketosis—a counterbalance that is defined by dietary indecision.
The new data meets supporters and critics in the middle. The researchers maintain that the diet has its functions; both as a quick and effective measure for weight loss and a provisional means of decreasing one’s risk for chronic illness.
However, very few fad diets warrant indefinite adherence.
“Our findings highlight the interplay between metabolism and the immune system, and how it coordinates maintenance of healthy tissue function,” said Emily Goldberg, the postdoctoral fellow in comparative medicine .”
In other words adopting the Keto diet in short spurts instead of committing to it long term appears to be the more effective method.
