All people fast or take a break from eating for at least 6-8 hours a day. That's right, when you sleep! This happens when you sleep.
New research suggests taking a longer break in the morning instead of eating breakfast early, may help you lose weight and improve overall health. Our intermittent fasting means that we intentionally take a "break" from eating for 16 hours a day.
Intermittent fasting has been shown
• Help lose weight and body fat
• Lower insulin levels (possible relapse of type 2 diabetes)
• Reduce inflammation
• Increase your metabolism
• Increase fat burning,
• Help with cell regeneration
• Improved mental clarity and concentration
• Increased energy
• Increased growth hormone
Here is a breakdown of what your body does every hour with intermittent fasting (after your last meal):
About 4-8 hours
• Blood sugars fall
• All food has left the stomach
• Food from the stomach has been burned as energy
Insulin is no longer produced
About 9-12 hours
• The digestive system is asleep
• The body begins to switch to stored fat as an energy source
• The body begins to heal
• The body begins to produce fat burning hormones such as;
- Human growth hormone
- Glucagon (to balance blood sugar)
- Testosterone
- Adrenaline
About 12-16 hours
The body has converted to use stored fat as energy and ketones are released to provide energy to the heart, brain and other vital organs
Human growth hormone begins to increase dramatically
Cell renewal (Autophagy) begins and old / defective cells are recycled or renewed
Surely it's amazing? Weight loss is just one of the many health benefits of intermittent fasting.
