Intermittent fasting – pros and cons

Intermittent fasting has become one of the most popular approaches to weight loss and dietary change in recent years. Many people associate it with faster weight loss, better appetite control, and processes such as autophagy. However, experts emphasize that no single dietary approach is a universal solution for everyone. Modern obesity management increasingly relies on a multidisciplinary approach, and Galenika’s recent introduction of GLP-1 therapy in Serbia has further expanded the conversation about more sustainable ways to manage body weight.
What is intermittent fasting?
Unlike traditional diets that focus on what we eat, intermittent fasting focuses on when we eat. The most common approach involves fasting for 16 hours and consuming all meals within the remaining 8-hour eating window. The idea behind this eating pattern is that, during periods without food, the body begins to use energy differently, which may influence metabolism, blood sugar levels, and appetite regulation.
Why has it become so popular?
One of the main reasons for the popularity of intermittent fasting is its simplicity. Many people find it easier to limit the time frame in which they eat than to follow complicated diets or strict meal plans. It is also frequently associated with autophagy—the body’s natural process of removing damaged cellular components. Although autophagy is often presented as one of the major benefits of fasting, experts note that its effects should still be interpreted with caution and considered within the context of an individual’s overall lifestyle.
Why don’t we all respond the same way?
While intermittent fasting may help some people regulate body weight and appetite, others may experience fatigue, irritability, overeating after fasting periods, or difficulty maintaining the routine. Modern medicine increasingly recognizes obesity as a complex metabolic disease rather than simply the result of unhealthy habits. For this reason, experts emphasize that dietary approaches should be tailored to each individual’s needs, health status, and daily routine.
Fasting is not the same as a balanced diet
One of the most common misconceptions is that simply avoiding food for a certain number of hours is enough, regardless of food quality. However, even during intermittent fasting, consuming large amounts of highly processed foods and calorie-dense meals can make weight loss more difficult. Sustainable results are most often achieved through a combination of a balanced diet, regular physical activity, and long-term lifestyle changes.
There is no universal solution
Experts increasingly emphasize that successful obesity management requires a multidisciplinary approach tailored to each individual. This includes a combination of lifestyle changes, psychological support, and medical therapy when appropriate.
Today, GLP-1 therapies represent one of the most significant advances in modern obesity treatment. By recently introducing these therapies in Serbia, Galenika has further expanded the options available for a sustainable approach to weight management.
