Nutrition window - the key to metabolic health

What is intermittent fasting (IF) or a nutritional window? There is certainly not another diet, but the way of organizing meals in time. Imagine that your body acts as a precise clock mechanism that needs both periods of activity and rest. And this is the idea of ​​a nutritional window - we set specific hours to eat meals, and for the rest of the day we allow the body to regenerate.

The most popular model is 16/8, where we refrain from eating for 16 hours, and we eat all meals in an 8-hour window. For example, if we eat the first meal at 12:00, the last one should end before 20:00.

What happens in the body during fasting? Studies conducted by the team of Dr. Valter Longo from the University of Southern California show that after about 12 hours without eating the body switches to an alternative energy source. It begins to use the accumulated fat. However, that's not all.

A breakthrough study published in "Cell Research" in 2019 showed that the regular use of a nutritional window can improve insulin sensitivity and reduce the risk of type 2 diabetes. What's more, scientists from the Salk Institute have found that limiting the time of consuming meals can support cell regeneration through the process of autophagia - natural "recycling" of damaged cell elements.

Benefits with Intermittent Fasting (IF)

Positive effects go beyond weight reduction. Include:

• Improving cognitive functions and concentration
• Extending the life of cells
• Reduction of inflammation in the body
• Stabilization of blood sugar levels
• Metabolism optimization

How to start an adventure with Intermittent Fasting - a practical guide

• Last meal: 20:00
• The first meal: 8:00 This scheme is most similar to the body's natural rhythm.

3. Progression phase (week 3-4): gradually extend the time of fasting:

• Week 3: Diagram 14/10
• Week 4: Scheme 16/8 (the most popular)

• People with low BMI
• People taking medications requiring a meal

Typical difficulties and how to deal with them:

1. Morning hunger

• Drink more water
• Plan engaging classes
• Gradually extend the time of fasting

2. Energy drops

• Take care of the electrolytet
• Adjust the intensity of training
• Make sure you eat enough in the nutrition window

In the light of the latest research, the nutrition window appears as a powerful tool in caring for metabolic health. This is not a temporary trend, but a scientifically proven method supporting the body's natural regenerative processes.

Remember: if it's not a race - success is to find a balanced approach that you can keep in a long time. Listen to your body and adapt the protocol to your needs.
