The eatingwindow (diet if – intermittent fasting diet) is the so-called metabolic window, which determines the determination of the time of eating during the day or week. There are many variations of this diet, but its main idea is to determine when, not what, we should eat. Fasting periods are punctuated by a metabolic window, which is when we can consume a meal.

Eating window – method if, diet rules

The eating window is a relatively young diet, which at the same time is very different from other popular diets. These mostly indicate what you should and should not eat. The principles of the intermittent fasting diet are simple. The eating window or metabolic window is an 8-hour eating or fasting period on certain days throughout the week. During the if diet, 100% of the daily energy pool is consumed. The multi-hour version a specific time during the day when 100% of the daily energy pool is consumed. The standard division is 16 hours of fasting and 8 hours of eating. The diet, is used most often in 3 variants, such as: 16/8, 18/6, 20/4.

  • TRF diet – used in variants: 16h of fasting and 8 food; 18 hours of fasting and 6 food; 20 hours of fasting and 4 food.
  • ADF/EODF diet – a 24-hour period of eating low-calorie foods usually about 800 kcal less per day than the standard, followed by 24 hours of eating without restriction.
  • PF / WDF diet – a 24-hour period of eating followed by a 24-hour fasting period. Cycle repeated 2-3 times a week.

In addition, water can be consumed during the fasting period, and tea, coffee and herbal infusions in small amounts.

Intermittent fasting diet – how does it affect health?

The IF (intermittent fasting)diet, or in other words our eating window, allows our body to digest properly, which also affects weight loss. This goes through so much more smoothly, as long as we join this diet already having healthy eating habits. This is important, for the reason that during the diet window, we are able to ensure that we have properly balanced nutrition. Because although the intermittent diet does not presuppose the consumption of specific products and does not prohibit any either, a rational approach to nutrition during the eating window is advisable. What are the additional advantages of the eating window?

  • The longer we follow the IF diet, the easier it will be to reduce hunger attacks.
  • Rapid fat reduction – following the recommendations of the eating window, with physical activity we are able to lose up to 4-5 kg in a month.
  • Accelerated metabolism.
  • Better work of the digestive system. Longer night fasting contributes to better liver regeneration.
  • Better sleep – the body rests at night instead of digesting, which affects better and deeper sleep.
  • It can have a preventive effect on the incidence of diseases such as Alzheimer’s and Parkinson’s.

IF diet may work differently on everyone, it mainly depends on our maintenance of the rules of eating hours, without snacking or irregularity of the diet.

Diet window disadvantages and contraindications

The use of intermittent fasting is not for everyone, and it also has its drawbacks. First of all, pregnant or nursing women should not go for it. In addition, it is also not recommended for people with kidney or liver problems, people with hormonal imbalances should also absolutely avoid this diet, as should diabetics and those recovering from surgery. What disadvantages does the 8-hour diet have?

  • Using this diet for a long time, can slow down our metabolism. Therefore, it is worthwhile to carry it out only periodically.
  • Also, long-term use of the IF diet can cause the production of digestive enzymes, as well as cause gastric reflux by the excessive amount of food eaten in one meal.

Intermittent fasting for whom? When to use the diet?

It can be said that the nutritional window is used unconsciously by a large part of society, which lives in a constant rush. Many people forgo breakfast, for a longer night’s sleep or simply do not feel like eating in the morning, but opt for coffee. As a result, the consumption of the first course, often occurs around 12 pm, and later around evening. So it can be said that this diet is simply a lifestyle for some. However, it is primarily recommended for healthy people, including those who are quite physically active. In the case of professional athletes, there are no conclusive results indicating a specific effect of intermittent fasting, on sports performance. However, it is claimed that building a lot of muscle mass using an IF diet is rather unlikely. Above all, the eating window can be an attractive diet, for people who want to lose excess weight.

Eating window vs. nighttime hours

The term “nutrition window” refers to a specific time frame in which we consume meals and calories during the day. In the context of “bedtimes,” it refers to the period of time when we eat at night, usually after standard evening hours, close to bedtime or late at night.

There is debate among experts about eating at night. Some studies suggest that eating just before bedtime can affect sleep quality and metabolism. Taking in calories before bedtime can lead to slower digestion, which adversely affects sleep. In addition, the body would go into resting mode at night, and consuming a lot of calories can interfere with this process.

However, it is worth noting that individual dietary needs vary, and there is no single “right” dietary window for everyone. It is worth paying attention to the quality of the meals we eat, their ingredients and our own well-being. People who work non-standard hours or lead active lifestyles may have different nutritional needs. In any case, it is advisable to consult a nutritionist or healthy lifestyle specialist to tailor nutrition to individual needs and goals.
