Becky wrote to me asking, "Sara, Is fasting just a way for lean people to shed the last 5 pounds of stubborn fat? Will it also work for someone who has 50 to 100 pounds of fat to lose? And how long do you have to be on this fasting diet?

Great Question!

Fasting works for both scenarios. Some of my followers have lost 100 pounds! Others have finally shed the layer of stubborn fat hiding their lower abs.

By the time you hit the 16-hour mark of your fast, you are in a state of pure fat oxidation, meaning, you are burning fat for energy.  When you fast, not only do your catecholamine levels rise, but so does your abdominal subcutaneous blood flow. This increased blood flow makes it easier for your catecholamines (epinephrine) to access your stubborn fat areas and trigger a series of events that will break down stubborn fat.

Fasting is a lifestyle, it's not a diet. It merely tells you when you can eat and when you cannot eat during your waking hours. Once you start doing it, you will get your groove going, and you'll never want to stop! I've been doing it since 2012.

Fasting is intended for use by healthy adult individuals. Make sure you consult with your doctor to ensure fasting is right for you.
