What is Keto Diet?

Keto diet: The high-fat, moderate-protein and low-carb ketogenic diet is among the foremost popular weight loss methods. The diet forces the body to burn fats instead of carbohydrates.

What is a ketogenic, or ‘keto’ diet?

The ketogenic diet is one amongst the foremost popular weight-loss diets the globe over. It’s a high-fat, moderate-protein, and low-carb diet that helps in weight loss by achieving ketosis — a metabolic state where the liver burns body fat and provides fuel for the body, as there’s limited access to glucose. It has many benefits for weight loss, health, and performance, A keto diet can be especially useful for losing excess body fat without hunger and for improving type 2 diabetes.
While you eat far fewer carbohydrates on a keto diet, you maintain moderate protein consumption and you may increase your intake of fat. The reduction in carb intake puts your body in an exceedingly metabolic state called ketosis, where fat, from your diet and from your body, is burned for energy.

What the term "Keto" means?

A “keto” or “ketogenic” diet is so named because it causes your body to provide small fuel molecules called “ketones.” this is often an alternate fuel source for your body that may be used when blood sugar (glucose) is briefly supply. Once you eat only a few carbs or very few calories, your liver produces ketones from fat. These ketones then function a fuel source throughout the body, especially for the brain. The brain is a hungry organ that consumes a lot of energy on a daily basis, and it can’t run on fat directly. It can only run on glucose – or ketones.

What constitute a Keto diet?

A classic keto requires that 90 percent of a person’s calories come from fat, six percent from protein, and 4 percent from carbs. But there are many versions doing the rounds since this one was designed for kids affected by epilepsy to achieve control over their seizures. Typically, popular ketogenic diets suggest an average of 70-80 percent fat, 5-10 percent carbohydrate, and 10-20 percent protein,
So, on a ketogenic diet, your entire body switches its fuel supply to run totally on fat, burning fat 24-7. When insulin levels drop very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off.
This is a decent thing if you’re trying to reduce , but there also can be other benefits, like less hunger and a gentle supply of energy — without the sugar peaks and valleys that always occur when eating high-carb meals. This could help keep you alert and focused.
When your body produces ketones, it enters a metabolic state called ketosis. The fastest process to get there’s by fasting – not eating anything – but nobody can consistently fast forever.
A keto diet, on the other hand, also leads to ketosis and may be eaten indefinitely. it’s many of the advantages of fasting – including weight loss – without having to fast long run.

Who should not be on a ketogenic diet?

There are several controversies and myths about a keto diet, but for most people it appears to be very safe. However, three groups often require special consideration and guidelines as well:

Types of Ketogenic Diets-

There are several versions of the ketogenic diet, these are including:

  • Standard ketogenic diet (SKD): This is a very low-carb, moderate-protein and high-fat diet. It typically contains 75% fat, 20% protein and only 5% carbs.
  • Cyclical ketogenic diet (CKD): This diet involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
  • Targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.
  • High-protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein and 5% carbs.

However, only the standard and high-protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.

  • Heart disease: The ketogenic diet can improve risk factors like body fat, HDL cholesterol levels, blood pressure level and blood glucose.
  • Cancer: The diet is currently getting used to treat several kinds of cancer and slow tumour growth.
  • Epilepsy: Research has shown that the ketogenic diet can cause massive reductions in seizures in epileptic children.
  • Alzheimer’s disease: The keto diet may reduce symptoms of Alzheimer’s disease and slow down its progression.
  • Polycystic ovary syndrome: This diet can help reduce insulin levels, which may play a key role in polycystic ovary syndrome.

Other side effects can include the “keto flu,” which can include headache, weakness, and irritability; bad breath; and fatigue.
Keto flu includes poor energy and mental function, increased hunger, sleep issues, nausea, digestive discomfort, and decreased exercise performance.

To minimize this, you can try a daily low-carb diet for the primary few weeks. This might teach your body to burn more fat before you completely eliminate carbs. A ketogenic diet may also change the water and mineral balance of your body, so adding extra salt to your meals or taking mineral supplements can help. Many of the side effects of starting a ketogenic diet are often limited. Easing into the diet and taking mineral supplements can help.

  • MCT oil- Added to drinks, food or yogurt, MCT oil provides energy and helps increase ketone levels.
  • Minerals- Added salt and other minerals can be important when starting out due to shifts in water and mineral balance.
  • Creatine- Creatine provides numerous benefits for health and performance. This can help if you are combining a ketogenic diet with exercise.
  • Exogenous ketones- This specific supplement may help raise the body’s ketone levels.
  • Whey- You can use Whey protein in shakes or yogurt to increase your daily protein intake.
  • Caffeine- Caffeine can give you the benefits for energy, fat loss and performance.

Ketogenic Diet Is Great, but Use This Diet With Care

A ketogenic diet may be great for those who are overweight, diabetic, or looking to boost their metabolic health.

It may be less suitable for elite athletes or those wishing to add large amounts of muscle or weight.
When your body burns its stores of fat, it may be hard on your kidneys. And starting a ketogenic diet — or going back to a standard diet afterward– can be tricky if you’re obese due to other health issues you’re likely to possess , like diabetes, a heart disease , or high blood pressure. If you’ve got any of these conditions, make diet changes slowly and only with the guidance of your doctor.
