The percentage of fat burned after 12 hours of fasting is estimated to be between 37% and 42%, based on common fasting windows.
While it's difficult to give an exact amount of fat burned after 12 hours of fasting without knowing individual metabolic rates and activity levels, we can provide an estimate based on available data. The most common fasting window is between 11 and 15 hours, during which the body derives approximately 37% to 42% of its energy from fat stores. (Reference: 15-Aug-2024 data.)
Here's a breakdown of factors influencing fat burning during fasting:
- Fasting Duration: The longer the fasting period, the more likely the body is to tap into fat reserves for energy.
- Individual Metabolism: Metabolic rate differs from person to person, affecting how quickly they burn fat.
- Activity Level: Engaging in physical activity during fasting can increase fat burning.
- Dietary Habits: Prior dietary habits and macronutrient intake play a role in how the body utilizes energy sources during fasting.
In conclusion, while a specific quantity of fat burned after 12 hours of fasting is elusive without individual data, the provided data suggests fat contributes significantly (37% - 42%) to energy expenditure during this period.
