Advisory

Hello.
I would like to ask about your or your students' or clients' experiences with transitioning to intermittent fasting, or any potential obstacles they had to overcome. Did they or you initially experience any negative feelings or reactions from the body to the change, and what were the positive responses? I'm currently trying it myself, in the first week. In the mornings, I feel a bit tired, and I'm trying to meditate every morning, drinking about 2 liters of water in the morning. I'm also trying to set up a high-carbohydrate diet to make it as balanced as possible. Transitioning from 5 meals a day to 3. It's not just about handling it "on paper"—that is, in the meal plan—but also practically, and I'm really experimenting with meal combinations. I can't always maintain a medium glycemic index in a portion. However, overall for the day, the glycemic index is low to medium.
Thank you.

Every change in eating habits is accompanied by a reaction from the body. Depending on an individual's metabolic profile and the extent of changes, these manifestations are either more pronounced (uncomfortable) or, conversely, the individual manages them without significant difficulties. With Intermittent Fasting (IF), the most common challenge is managing protests from the digestive tract, which, from the position of a long-term habit, demands food intake even in the morning hours (this also manifests in fluctuations in blood sugar levels with all the consequences). It is important to realize that these are natural, thus normal manifestations that cannot be avoided. Only their extent and the perception of these feelings varies for each person. The body possesses adaptive mechanisms, enabling it to adjust to a wide range of different situations. However, the rule of individuality also applies here, which means every individual reacts differently and the adaptation process varies in length – some may transition to the IF system immediately and without distress, while others have to manage a range of typical manifestations that can persist for several weeks.
