What is Keto Diet?

The Keto diet is a dietary plan that is mainly followed by people for losing weight. The human body is in a metabolic state is known as ketosis. In ketosis, the carbs present in the body are replaced with fats. This process also can convert fats into ketones. Ketones supply energy to the brain as well. The ketogenic diet is one of the safest diet plans.

Other than improving brain health, ketones are released in the liver. Because of the safest nature of the diet, it is one of the most commonly practised diet plans. In this dietary scheme, the emphasis is put on burning fat rather than burning other nutrients like carbohydrates. Other than that, the calorie intake, in this case, is deep.

In the standard ketogenic diet, the intake includes low carb levels, moderate protein levels and high-fat levels. In a cyclical ketogenic diet, cycles of diets are practised, 5 ketogenic days are practised with 2 days of high card intake days. In the targeted ketogenic diet, one can add cards only during their workout sessions. The high-protein ketogenic diet is similar to the standard ketogenic diet but has a high protein intake in it. The ratio has 60 per cent fats, 5 per cent carbs and 35 per cent proteins.

The ketogenic diet, if followed correctly, has several health benefits. Other than weight loss, it is also useful in PCOS and acne problems. It is also helpful in reducing the risks of several diseases like cancer various heart diseases, works as an aid for brain injuries, reduces the symptoms of Alzheimer’s disease and Parkinson’s disease, it also reduces epilepsy in children. 

What is Intermittent Fasting?

Intermittent fasting is a type of diet trend that includes fasting. It is mostly used for curing obesity, but it also has several other benefits. People often maintain a cycle, and alternatively, they decide when to eat and when to fast. The most common cycle practised by people in intermittent fasting is they either practise fasting for 16 hours or 24 hours twice a week. The concept of intermittent fasting is derived from the ancient period when people had to fast for a long time since there were no electrical appliances like refrigerators to store the fridge. 

There are three main types of intermittent fasting. In the first type, one has to skip breakfast and then eat in the next eight hours and again fast for the next sixteen hours. One can also fast twice a week for 24 hours. For instance, one can start fasting from one breakfast and continue until the next breakfast. In the 5:2 method, one can consume nearly 500-600 calories twice a week and then continue eating normally for the entire week.

The following processes occur in the body when we fast. There is an increase in the human growth hormone, which thereby increases insulin sensitivity. It helps to make the stored fat more accessible. When a person is fasting, their body experiences cellular repair processes. It also helps the human body to protect itself from diseases. The gene functioning also promotes longevity.

By practising intermittent fasting at some intervals of time, blood sugar levels are regulated. It also helps in reducing insulin resistance. Other than that, it helps in reducing inflammation. Risks of various diseases like cancer are reduced. However, intermittent fasting must be practised in a discontinued manner. Fasting for consecutive days can lead to serious health issues.
