Transition into a Fasting State
Consuming fewer calories than the body needs for maintenance, reduces the available glucose, forcing your body to find alternative energy sources.
From Day 2
Increased Fat Utilisation and Ketogenesis
As the available glucose supplies are reduced, the body starts to shift its metabolic processes to breaking down adipose tissue (fat cells). The body enters a state of ketogenesis, a metabolic state that encourages fat burning, preserves lean body mass, and supports cognitive function.
From Day 3
Enhanced Autophagy and Cellular Rejuvenation
In this state, the body initiates an enhanced and more efficient rate of autophagy, a cellular cleaning process where old, damaged cell components are broken down and recycled. Autophagy reaches a peak by day 4 improving metabolic efficiency and cellular fitness.
After Day 7
Once you start refeeding, your body shifts back to using glucose as its primary fuel source. This stage is critical for rebuilding and regenerating new, healthy cells, aided by the growth factors stimulated by nutrient-rich foods.
