The Real Reason Intermittent Fasting Burns Fat
Dr. Joshua Nderitu
If skipping breakfast really burned fat, everyone who rushes out the door in the morning would be lean. But they're not.
Because intermittent fasting doesn't work the way most people think it does. It is not about calorie restriction. It is about what happens hormonally when you give your body a break from food.
When you fast for 14-16 hours, your insulin drops low enough for your body to switch from burning glucose to burning stored fat. This is called metabolic switching. It also triggers autophagy — your body's cellular cleanup process.
But here's the catch: if you break your fast with ugali and soda, you spike insulin right back up and cancel most of the benefits.
