Researchers have found that pregnant ladies shouldn't binge-eat after 7 PM as it is linked to gaining weight. Lifetime Stock

Researchers have found pregnant women who consume more of the daily food intake after 7 p.m., and who have poor diet during pregnancy, more likely to gain weight.

Accroding to the study, published in the journal Nutrients, the same groups are three times more likely to experience postpartum weight retention of five kilogrammes or more, 18 months after giving birth.


The researchers from KK Women’s and Children’s Hospital (KKH), drew data from a large scale birth cohort study, GUSTO (Growing Up in Singapore Towards healthy Outcomes).

“Our research, based on multi-ethnic Asian women, shows that although predominantly night eating and lower diet quality have been independently linked with weight gain, practising night eating along with low diet quality demonstrated the greatest likelihood of substantial postpartum weight gain and retention even after 18 months,” study lead author Loy See Ling.

According to the researchers, there is evidence to show that retaining more weight after the first year of giving birth is associated with higher body mass index even at 15 years postpartum.

Weight retention after childbearing also appears to be more harmful than weight gain in other stages of life as the retained body fat is typically deposited in the abdomen (visceral fat) rather than in other parts of the body.

This phenomenon has a profound effect not only on the mother’s lifelong health including, metabolic and cardiovascular disease consequences, but also on subsequent pregnancies and the future health of her child.

Overall, 16 per cent of the 687 pregnant women involved in the study gained and retained five kilogrammes or more at 18 months after giving birth.

It was also found that a stronger likelihood of postpartum weight retention was observed when predominantly night eating was practised together with a higher diet quality, whereas those practising predominantly day eating with lower diet quality showed a weaker association with postpartum weight retention. The researchers suggest that night eating may be potentially more damaging than lower diet quality in contributing to substantial postpartum weight retention.

“Our body systems have evolved to metabolise food during the day and rest during the night. Hence, consuming more calories at night than day mismatches our body’s natural body time clock by disrupting the metabolic rhythm in various organs such as liver, stomach, pancreas, fat tissue, resulting in disruption of energy metabolism,” said study researcher Fabian Yap.

“The consumption of more calories at night is also closely linked with a later bedtime and hence, associated with overweightness and obesity,” Yap added. (IANS)

Bangladesh over the years show that the state has failed in its duty to protect minorities

If humanity is hurt, God is hurt.

Religion without compassion might give way to hatred. Compassion with a "self-interest" motive is completely irreligious. But of late, some of the religions have departed from those basic human values. Love and compassion are for only those who follow their "specific" faith. Very sadly, the religions are up as trading commodities in the world of proselytization. Better preachers attract more followers. Of course, no issue if they are not vying for their religious "supremacy". But the ground reality is utterly different. The claim for exclusive supremacy has become the first commandment --- a real bone of contention among the existing religions. In the name of religion, we have polluted our minds. we have corrupted our souls. We have also gone so much astray that God must have now shut his gateway to heaven!

Taking out time for family has become very difficult as people are pretty busy in daily life and find very little time to spend with their loved ones. Planning a family vacation is an excellent way through which the whole family can step away from their daily life and have fun. You can find many destinations for a family vacation, but there is no place that can beat Aruba.

Milky Way galaxy as seen from Chitkul Valley

NASA's Chandra X-ray Observatory has for the first time spotted signs of a planet transiting a star outside of the Milky Way galaxy, opening up a new avenue to search for exoplanets at greater distances than ever before.

The possible exoplanet -- or planets outside of our Solar System -- candidate is located in the spiral galaxy Messier 51 (M51), also called the Whirlpool Galaxy because of its distinctive profile, NASA said in a statement.

Astronomers have, so far, found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all of them less than about 3,000 light-years from Earth.

An exoplanet in M51 would be about 28 million light-years away, meaning it would be thousands of times farther away than those in the Milky Way, NASA said.

"We are trying to open up a whole new arena for finding other worlds by searching for planet candidates at X-ray wavelengths, a strategy that makes it possible to discover them in other galaxies," said Rosanne Di Stefano of the Center for Astrophysics at Harvard and Smithsonian (CfA) in Cambridge, Massachusetts, who led the study.

The findings are published in the journal Nature Astronomy.

The exoplanet candidate was spotted in a binary system called M51-ULS-1, located in M51. This binary system contains a black hole or neutron star orbiting a companion star with a mass about 20 times that of the Sun. The X-ray transit they found using Chandra data lasted about three hours, during which the X-ray emission decreased to zero.

Based on this and other information, the team estimates the exoplanet candidate in M51-ULS-1 would be roughly the size of Saturn and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun.

The team looked for X-ray transits in three galaxies beyond the Milky Way galaxy, using both Chandra and the European Space Agency's XMM-Newton. Their search covered 55 systems in M51, 64 systems in Messier 101 (the "Pinwheel" galaxy), and 119 systems in Messier 104 (the "Sombrero" galaxy).

However, more data would be needed to verify the interpretation as an extragalactic exoplanet. One challenge is that the planet candidate's large orbit means it would not cross in front of its binary partner again for about 70 years, thwarting any attempts for a confirming observation for decades, NASA said.

Named in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar, the Chandra X-ray Observatory is the world's most powerful X-ray telescope. It has eight times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope.

Known to the world as Chandra (which means "moon" or "luminous" in Sanskrit), Chandrasekhar was widely regarded as one of the foremost astrophysicists of the twentieth century. (IANS/JB)
