The New Year is traditionally a time for many to rethink their eating habits, as well as to start a new exercise regimen. , which is believed to have several health benefits. extra weight, chronic disease Also flag energy levelsBut what exactly is intermittent fasting? And will all the hype around it hold up to scientific scrutiny?
The term intermittent fasting encompasses several approaches, each based on different principles. Whichever method is used, it is important to note that the restriction only affects food intake, not water intake.

Judgment of science?
Your results will depend on the strategy you employ.
Relatively few scientific studies have been conducted on the “Eat Stop Eat” and 5:2 approaches.The sparse data available to us show that they can effectively help us lose weight When improve certain metabolic parameters fasting blood sugar, etc. For example, his Surabhi Bhutani, a nutritionist, said that after using the 5:2 method for three months he Participants’ weight loss of 3-6 kilograms.
However, both methods are very restrictive and side effects Days of complete fasting or severe calorie restriction — hunger, negative mood effects, and risk of hypoglycemia.
In the long term, restrictions also increase the risk of developing or exacerbating an eating disorder. yoyo dietThese patterns often emerge after individuals limit themselves and try to lose weight. Revival of old eating habits.
The most studied method is one in which food is consumed daily, but for a limited time.
-
It is known as “early timed feeding”, in which dietary intake begins at breakfast and ends in the late afternoon.
-
“Late time limit school lunch” in which the intake of meals starts at lunch.
This approach appears to improve metabolic regulation and reduce the risk of metabolic disease. However, these benefits will vary depending on the time slot you choose.When food intake began in the morning, the study observed weight loss When Improving insulin sensitivity.
vice versa, Little or no benefit Start eating at noon and finish in the evening. Ram Babu Singh’s team (Halberg Hospital and Research Institute, India) also Positive results for participants who ate only in the morning — not someone who ate dinner after 8pm
Why is there such a difference?
Research suggests that your body clock and circadian rhythms may be involved. Indeed, the advantage of eating only in the morning is that food intake and periods of fasting coincide with the biological clock.
in us previous articleexplained that in response to the light cycle, our bodies periodically produce hormones to adapt food intake to the body’s energy needs.Afternoon (around the time the sun begins to set, depending on the season).
Skipping breakfast and eating after 7:00 p.m. disrupts circadian rhythms and Increases risk of developing metabolic disease.
However, while timed diets appear to be a good approach to metabolic health, A lot is still not understood about how it works and how to optimize its effectiveness. Jobs in 2022 showed No change in weight loss Between early morning or late night meal choices. However, it did affect appetite during the day – this time in favor of the former.
And beyond the time of day when eating seems preferable, there may be other factors at work that are not necessarily measured in the studies conducted: the quality and quantity of food absorbed, the duration of the fast (12 It is also worth remembering that each individual has their own metabolism and may respond differently to fasting. New, more controlled and more comprehensive studies are needed to confirm and understand the mechanisms responsible for its effects.
What should I actually do?
Time-limited food intake appears to be the most appropriate way to avoid circadian clock disruptions (and thereby limit the risk of frustration and eating disorders) by synchronizing meals with circadian rhythms. It seems.
A typical day, therefore, consists of a hearty breakfast between 6-8am, lunch around noon, and finally an early dinner between 4-6pm, depending on the season. can be organized as
It’s not always easy to fit in with one’s social life. Practicing intermittent fasting in your family can be complicated if you have sports activities in the evening or work from the evening until 7 or 8 pm.
One solution is to eat a large breakfast and choose a meal that isn’t too high in calories at night so you don’t risk throwing your body clock off.

time nutrition
Chronic nutrition is becoming increasingly popular, and intermittent fasting appears to effectively boost metabolic health. Also, you need to make sure that the periods of fasting and food intake are consistent with your body clock.
Faced with many existing methods and potential risks, patients and medical professionals still face a lack of information. Further research is essential to better understand their effects. At present, there is still no general consensus on the ideal times to eat/fast or the optimal duration of each period. , may vary from person to person. Therefore, it is important to consider using this dietary strategy with a qualified health care professional in terms of setting up a healthy, balanced diet that limits the risk of complications.
