What is the Intermittent Fasting & How does it work?

Intermittent fasting (IF) is an eating pattern that cycles between periods of voluntary abstinence from caloric intake and windows of normal eating. By restricting the daily eating window, IF influences hormonal balance, appetite regulation, and overall energy homeostasis.

During the fasting phase, insulin levels drop, promoting lipolysis and increasing the body’s reliance on stored fat for energy. This metabolic shift can improve insulin sensitivity, support autophagy, and enhance mitochondrial efficiency.

The net weight change can be estimated by comparing an individual’s maintenance calories (M) with the average daily intake (C) over a week. A sustained caloric deficit leads to gradual fat loss.

\Delta W = \frac{(M – C) \times 7}{7700}
\Delta W = weekly weight change (kg)
