How to eat during weight loss? Many weight loss people have a lot of experience in this, "light fasting", "intermittent fasting" and other terms open their mouths, in the end, the core of these dietary methods is to reduce calorie intake, but different dietary methods promote different eating rules. Some recommend that our eating time in a day must be concentrated within 8 hours, some recommend that our caloric intake be 1/4 of normal for two days of the week, and the other 5 days of normal diet. Is it really that important to change your eating routine?
First, calorie restriction is the core of weight loss
Recently, the team of Professor Zhang Huijie of Southern Medical University said in the top medical journal "NEW ENGLAND JOURNAL OF MEDICINE": We don't have to care too much about what time to eat, as long as we can limit calorie intake. This means that "light fasting" and "intermittent fasting" are not important, just grasp the core "calorie restriction".
The researchers divided the 139 obese people into two groups, one group was to limit calorie intake (75% of normal calories) but not limit the time to eat, and the other group was to limit both calorie intake and meal time, and could only eat from 8 a.m. to 4 p.m. It was found that after 1 year, the weight of only calories was reduced by 6.3Kg, while the weight of calorie restriction and meal time was reduced by 8.0Kg.
It seems that limiting the meal time can reduce 4 pounds of meat, but please don't get too excited, in other indicators such as waist circumference, BMI, body fat rate, the difference between the two groups is not large, which shows that the various health benefits of the two groups are very close. Limiting meal times is not as effective as we thought.
This study tells us that whether it is "light fasting" or "intermittent fasting", the core of its weight loss is still calorie restriction, and limiting the time of eating does not make much sense.
Second, calorie restriction is still the key to life extension
Reducing calorie intake can not only lose weight, but more importantly, prolong life, and the Time Pie gz has a lot of discussion about calorie restriction. Calorie restriction can put cells into a "starvation" state, thereby activating the energy receptor AMPK and longevity protein sirtuins, inhibiting mTOR, changes in the activity of these enzymes will make the cells under great survival pressure, on the one hand, keep genes unharmaged, on the other hand, prompt the cells to eat themselves and save energy. Thus, calorie restriction can remove part of the senescent cells and stimulate the production of new cells, thereby prolonging lifespan.
Calorie restrictions, while reducing daily intake by 25 percent, are not as difficult to adhere to as they might think. Studies have shown that up to 83.8 percent of people adhere to a one-year calorie limit. Proper calorie restriction is mild, easy to accept, and can have the effect of weight loss and life extension.
Third, more anti-aging means are needed in the future
Calorie restriction is an anti-aging product discovered in the last century, and with the rapid development of biotechnology, anti-aging means are also more and more, such as the recent Bezos investment in Altos's "cell reprogramming" technology, which can allow mature cells to "return to youth", they have achieved the goal of making skin cells 30 years younger in just 13 days, the basis of this technology is based on the "Yamanaka factor" proposed by Shinya Yamanaka, who won the Nobel Prize in 2012. It was he who discovered that there are four factors that allow cells to re-transform into multifunctional embryonic stem cells and return to youthfulness.
In 2000, the United Nations Population Agency said that the aging of the population has risen to a global problem, and now, the aging problem of the mainland is also quite serious, we are about to move from mild aging to moderate aging, and the future is likely to fall into the passive situation of "not getting rich before getting old".
Singapore, which is equally ageing, has been aware of this problem in previous years, so in recent years it has vigorously developed anti-aging technology to extend the life expectancy of more people. The mainland has also begun to increase investment in scientific research in the field of anti-aging, and perhaps in the near future, we mentioned that anti-aging is not only calorie restriction and reprogramming, but also more and more effective "weapons" to intervene in aging.
