Keto Diet

The ketogenic diet, also called the keto diet, is a trend meal plan nowadays. The keto is very similar to the Atkins and low carb high-fat diet (LCHF), but they have some partial differences. In the 1920s, the keto diet was taken as a treatment for epilepsy and controlling seizures. A keto diet can also help prevent diseases such as cancer, diabetes, and Alzheimer's. In the continuation of this article, we will give you a complete guide about the ketogenic diet.

What Is Keto Diet?

Our body uses two sources of substances to burn and then produces energy for each cell. The first one is sugar and the second is ketones. There are a lot of pathways to generate energy from the foods we eat. While carbohydrates and proteins provide glucose(sugars), ketones come from breaking fats called ketosis. Ketosis is a state of routine metabolism in the body; this is why we call it a keto diet. The keto diet is a Low Carb, High fat diet and leads the liver to breakdown the function of fats. There are different types of keto diet based on the intake percentage of each macronutrient. For instance, Standard Keto Diet (SKD), Targeted Keto Diet (TKD), Cyclic Keto Diet (CKD), and High Protein Ketogenic Diet. For example, in a high protein keto diet, protein is about 35% of total calorie intake. The standard keto diet is very familiar and habitual for losing weight. The targeted keto diet and the high protein keto diet are suitable for people who follow powerful workouts, such as bodybuilders, powerlifters, and fitness enthusiasts.

Keto Diet Plan

Keto diet Macronutrient

A large percentage of the keto diet consists of fats, which contradict most of the other diets. The Carbohydrates are cut off from the plate, limiting your options in choosing foods. Carbohydrates exist in most foods, so eliminating them may be hard for those who want to start and continue a keto diet. Decreasing the amount of carbohydrate intake to less than 50 grams per day (20-gram net carbohydrate) means consuming particular foods; for example, a mid-size banana (100 grams) contains around 27-grams carbs, pasta contains 25-gram carbs, or a small potato includes 17 gram of carbs. So you can compare the total intake with these foods to know how much you need to cut off the carbs in your keto diet.

How Keto Diet Works

The pathway of producing energy depends on the kinds of food you eat. If you consume more carbohydrates than fats, the body switches to burning carbs and using glucose. So, if the fat intake increases, the body will switch to burning fats, and then the ketosis state works. It should be considered that increasing the percentage of protein intake leads the body to glucose expenditure and prevents ketosis. Therefore, protein intake is moderately limited in the ketogenic diet.
In the first days of keto dieting, the body releases stored glucose from the liver and muscles for the brain and cells until the body starts to decrease the insulin hormone. After that, the liver converts the body fats to ketones for the cells and the fat burning start.

Foods to Avoid in Keto Diet

Refined carbohydrates, starch, fruits, vegetables, nuts, and dairy, which are containing carbohydrates, should be eliminated. So, if you want to follow a keto diet, you have to cut off these foods from your keto meal list:

Foods That Are Allowed in the Keto Diet

Fats and Oils

While we need necessary fat from nutrients, consuming the wrong type of fat can put our health at risk.
Trans fats are the kind of unhealthy fats that should be totally avoided. These fats have a long shelf life due to their hydrogenated process, and they can damage the heart and arteries.
Medium-chain triglycerides (MCTs) were found in the 1960s. They can produce more ketones than other fats.

Keto Diet Pills

There are many ketosis booster pills in the markets that people tend to use during their keto diet. Exogenous ketones, also known as keto pills, alter the cholesterol levels and improve energy production by reducing lactate accumulation. Controlling appetite is another role they can have. These pills are trendier and common among athletes. They also have some disadvantages like mild side effects such as fatigue, hunger, and repeated urination.
Generally, you should not expect some medications as an easy way of losing weight.

Keto Diet and Diabetes

Diabetic people who follow the keto diet should calculate carbohydrate intake and ketone levels in their body because a high level of ketones leads to ketoacidosis and DKA (Diabetic Ketoacidosis) happens. If patients don’t use insulin regularly along with their meal schedule, they can suffer from ketosis. This ketoacidosis is more common in type 1 diabetes than type 2 and can take place so fast, maybe less than 24 hours and will poison the patient.
Keto diet can be a successful way of controlling blood sugar and insulin levels and also decreases the use of medications.
