Science
Understand your fasting zones
Your body goes through 8 distinct metabolic phases during a fast. FastBreak tracks each one in real time.
Your body digests your last meal. Blood sugar and insulin levels rise as nutrients are absorbed into the bloodstream.
Insulin drops and your body begins tapping into glycogen reserves stored in the liver and muscles for energy.
Liver glycogen is running low. Your body starts looking for alternative fuel sources and prepares the metabolic switch.
The critical transition. Your body shifts from burning glucose to burning stored fat as its primary energy source.
Fat oxidation is in full swing. This is where the 16:8 protocol hits its peak effectiveness for weight loss.
Ketone production increases significantly. Many people report enhanced mental clarity and sustained energy.
Your cells activate their cleanup process, recycling damaged proteins and components. Cellular renewal at work.
Extended autophagy and deep cellular repair. Growth hormone levels rise. Only recommended under medical supervision.
