Carbohydrates and sugar: how do liquid calories and sugary drinks affect energy levels in IT professionals?

For developers and specialists who spend many hours in front of a monitor, maintaining a stable energy level is critical for productivity. One of the main hidden enemies of concentration is liquid calories, such as sugary carbonated drinks, store-bought juices, energy drinks, and coffee with syrups. Unlike solid food, liquid carbohydrates are absorbed by the body almost instantly, bypassing the stage of prolonged chewing and partial breakdown in the oral cavity.

This leads to a sharp and powerful release of glucose into the blood, which doctors call a sugar spike. In response, the pancreas secretes a huge dose of insulin to utilize excess sugar. As a result, glucose levels drop below normal, causing a state of hypoglycemia. It is precisely because of this that just an hour after drinking a can of an energy drink or sweet coffee, a programmer feels severe fatigue, drowsiness, brain fog, and an irresistible desire to eat something else sweet.

To break this vicious circle and maintain performance throughout the working day, you should gradually replace liquid sugar with healthier alternatives. Simple steps for transitioning to a proper drinking regimen include the following actions:

Introducing these habits will help avoid energy crashes during important sprints and deadlines, improve cognitive functions, and eliminate tension headaches often associated with fluctuations in blood sugar levels.
