What Is the Keto Diet and Does It Work?

Nowadays everyone seems to be talking about the ketogenic diet-very low carbs, moderate protein, a high-fat diet plan that turns your body into a fat-burning machine. Hollywood stars and professional athletes publicly advertise the benefits of this diet, including weight loss, lowering blood sugar, fighting inflammation, reducing cancer risk, increasing energy, and slowing aging. So is Keto something you should consider taking on? The following describes what this diet is, its pros and cons, and the issues to be aware of.

What is Keto?

Normally, the body uses glucose as the main fuel source of energy. If you are on a keto diet and are eating carbohydrates that contain only modest amounts of protein (excess protein can be converted to carbohydrates), your body will switch fuel supplies, mainly fat Run with. The liver generates ketones (a sort of fatty acid) from fat. These ketones are a source of fuel for the body, especially the brain, which consumes a lot of energy and can run on either glucose or ketones.

When the body produces ketones, it enters a metabolic state called ketosis. Fasting is the easiest way to achieve ketosis. When you are fasting or eating very few carbohydrates and modest amounts of protein, your body will begin to burn fat stored for fuel. So people tend to lose weight on a keto diet.

Keto diet benefits

The keto diet is not new. It began to be used as a medical therapy to treat childhood epilepsy in the 1920s, but when antiepileptic drugs came to market, the diet was ambiguous until recently. Given the success of reducing the number of seizures in epilepsy patients, more and more research is being done on the ability of a diet to treat various neurological disorders and other types of chronic illness.

Neurodegenerative Disease.

New research shows Keto’s benefits in Alzheimer’s disease, Parkinson’s disease, autism, and multiple sclerosis (MS). It may also protect against traumatic brain injury and stroke. One theory of the neuroprotective effect of keto is that the ketones generated when ketosis may produce additional fuel to brain cells and help these cells resist the inflammatory suffering caused by these diseases.

Obesity and weight loss.

If you’re trying to lose weight, a keto diet can be very effective in helping you access and eliminate body fat. Constant hunger is the biggest problem when trying to lose weight. A Keto diet helps to avoid this problem. This is because reducing carbohydrate consumption and increasing fat intake increase satiety and make it easier for people to stick to their diet. In one study, obese subjects lost twice as much weight within 24 weeks when they ate a low-carb diet (20.7 lbs) compared to a group that ate a low-fat diet (10.5 lbs).

Type 2 Diabetes.

In addition to weight loss, the keto diet also helps increase insulin sensitivity. This is ideal for people with type 2 diabetes. In a study published in Nutrition & Metabolism, researchers noted that diabetics who ate low-carb keto diets could significantly reduce their dependence on diabetes drugs, and even reverse it. In addition, it improves other health markers such as lowering triglycerides and LDL (bad) cholesterol and raising HDL (good) cholesterol.


Most people are unaware that glucose is the main fuel for cancer cells. In other words, a proper diet can prevent the growth of cancer. Keto diets are so low in carbohydrates that they deprive cancer cells of their primary source of fuel, sugar. When the body produces ketones, healthy cells can use it as energy, but cancer cells cannot. As a result, they effectively starve and die. As early as 1987, studies on keto diets already demonstrated reduced tumor growth and improved survival for many cancers.
