Te Science Behind Fasting and Diabetes Management

Fasting involves applicarilis abstaing from food and caloric contragages for a set period. For individuals with diabetes, this practique can trigger metabolic adaptations that may improe bloody glucose regulation. During a fast, thee body depletes glykogen stores and shifts to using stored fat for energiy, a process knoss as metabolic speng.

Breaking the fast beween 8 and 10 AM aligns with the highett insulin sensitivity period and the body 's natural cortisol peak, which helps mobilize glukose for energiy. This window typically correcdos to a time- restricted eating schedule of 8 AM to 4 PM or 8 AM to 6 PM.
