Have you ever wondered why some people can lose weight easily while others struggle without success? The answer may lie in intermittent fasting, a method that has transformed the lives of thousands, revolutionizing how we think about weight loss and health.
[Synonyms used: scheduled food restriction, interval eating, fasting diet, 16/8 protocol]
What is Intermittent Fasting? ⏰
Unlike traditional diets that constantly restrict calories, interval eating focuses on “when” to eat, not “what” to eat. According to Harvard Medical School, this natural method activates ancestral fat-burning mechanisms.
The most popular protocol is 16/8: fasting for 16 hours, eating within 8 hours. To better understand all types of fasting protocols available, we recommend reading our comprehensive guide.
The Science Behind the Method
According to the National Institute of Health, when we practice scheduled food restriction, our body undergoes several metabolic adaptations:
- Significant reduction in insulin levels
- 500% increase in growth hormone
- Activation of autophagy (cellular cleaning)
- Improved insulin sensitivity
- Increased norepinephrine production
- Optimization of mitochondrial function
- Reduction of oxidative stress
