What is Intermittent Fasting?
Basics of intermittent fasting
How does intermittent fasting work?
Intermittent fasting is a dietary pattern that limits eating to certain periods of time. In this method, food is eaten at certain times of the day and the body is allowed to rest at other times. The basic logic of intermittent fasting is to accustom the body to not eating for long periods of time and to use the body's energy stores to burn fat during this time. Short periods of fasting speed up metabolism and promote weight loss.
Intermittent Fasting Methods
Popular types of intermittent fasting
16/8 method
One of the most common methods of intermittent fasting is the 16/8 method. In this method, nothing is eaten for 16 hours and only water, coffee or sugar-free drinks are consumed. During the remaining 8 hours, meals are eaten. For example, you can start eating at 10:00 in the morning and have your last meal at 18:00 in the evening. This method allows the body to utilize fat stores while limiting daily calories.
5/2 method
Another popular intermittent fasting method is the 5/2 method. In this method, you eat normally 5 days a week and severely restrict calories on the other 2 days. Usually 500-600 calories are consumed on restriction days. This method speeds up the metabolism and directs the body to burn fat with a constant calorie deficit. It is considered an effective way for those who want to lose weight.
24-hour fasting (Eat-Stop-Eat)
A harsher version of intermittent fasting, it involves fasting completely for 24 hours once or twice a week. For example, after lunch one day, nothing is eaten until the same time the next day. This is an effective method that forces the body to use its fat stores. However, it requires discipline and can be challenging at first.
Intermittent Fasting and Metabolism
How does intermittent fasting affect metabolism?
Metabolic rate and intermittent fasting
Intermittent fasting can have a positive effect on metabolic rate. During periods when you don't eat, your body starts to use stored fat as an energy source. During this process, the metabolism switches to fat-burning mode, which promotes weight loss. Research has shown that intermittent fasting lowers insulin levels, increases growth hormones and promotes cellular repair processes.
Intermittent fasting and fat burning
When you don't eat for a long time, your body starts to produce glucose from fat cells to meet its energy needs. This accelerates fat burning. During intermittent fasting, the body starts using fat for energy after depleting glycogen stores. Thus, a significant reduction in fat stores is achieved. Especially with the 16/8 or 5/2 methods, weight loss and fat burning can be achieved in the long term.
Healthy Weight Loss with Intermittent Fasting
The benefits of weight loss with intermittent fasting
Controlling calorie intake
Intermittent fasting is an ideal method for those who want to lose weight. Because you limit the time you eat, you take in fewer calories throughout the day. This accelerates weight loss. At the same time, when you fast for a long time, your body starts to use stored fat to meet its energy needs. This process increases fat burning and helps you lose weight.
Improving insulin sensitivity
One of the biggest benefits of intermittent fasting is that it improves insulin sensitivity. Regular eating and a diet that restricts calorie intake stabilizes blood sugar levels by balancing insulin levels. This reduces the risk of diabetes and supports overall health. At the same time, lower insulin levels slow down the process of fat storage and increase the body's capacity to burn fat.
Things to Consider During Intermittent Fasting
What not to do during intermittent fasting
Food choices
Intermittent fasting should be supported by good food choices. Eating unhealthy and high-calorie foods outside mealtimes can cause weight gain instead of weight loss. Therefore, fresh vegetables, protein-rich foods and healthy fats should be preferred during fasting periods. Fiber-rich foods also provide long-lasting satiety and give the body balanced energy.
Water and fluid consumption
Fluid consumption is very important during fasting. Water keeps the body hydrated during fasting and helps flush out toxins. In addition, water consumption is a very effective method to suppress the feeling of hunger. In addition to water, unsweetened herbal teas and black coffee can also be consumed during intermittent fasting periods. Paying attention to fluid intake will increase the positive effects of fasting on the body.

Heart health benefits
Intermittent fasting can have positive effects on heart health. Research shows that this dietary pattern reduces the risk of heart disease by stabilizing cholesterol levels. In addition, intermittent fasting regulates blood pressure and reduces inflammation levels. This protects cardiovascular health.
Cellular regeneration and aging
During periods of fasting, the body undergoes autophagy, a process that increases the repair of cells. In this process, the body removes damaged cells and toxins. The accelerated process of cellular regeneration reduces the signs of aging and supports skin health. In addition, the healthier functioning of cells contributes to improved overall health and energy levels.
Who is not suitable for intermittent fasting?
In which cases should intermittent fasting not be practiced?
Women during pregnancy and lactation
Intermittent fasting is not recommended for women during pregnancy and breastfeeding. During these periods, the body needs extra energy and nutrients. Fasting can make it difficult to meet these needs and put the health of mother and baby at risk. Therefore, intermittent fasting should be avoided during this period.
Those with a history of eating disorders
Intermittent fasting can also be risky for people with a history of eating disorders. Prolonged fasting can trigger an eating disorder and can be psychologically challenging. In such cases, it is important to talk to a health professional and create a more appropriate eating plan.
Intermittent fasting is an effective dietary pattern that speeds up metabolism, increases fat burning and aids weight loss. When practiced correctly, it provides many health benefits and contributes to weight control. However, it is important to remember that this method is not suitable for everyone. Consulting a specialist before practicing intermittent fasting will help you achieve healthier and more sustainable results.
