As obesity rates across the world continue to rise, understanding exactly why we put on weight has never been more important. That’s why the findings of a new study, which looked at whether there is an association between when we eat and how much weight we gain, could be very significant. Presenting their findings at the ENDO 2019 conference, which took place in New Orleans, the scientists from the University of Colorado in Denver said there is a link between eating later in the day and having a higher BMI, as well as more body fat. For the study, 31 adults who were either overweight or obese and had an average age of 36 years were closely monitored to assess their sleep, levels of activity, and diet. Interestingly, the study also showed that the participants who ate later in the day still had an average of 7 hours sleep each night, suggesting that lack of sleep may not promote obesity after all. Speaking about the findings of the study, Dr. Adnin Zaman, lead author, said “These findings support our overall study, which will look at whether restricting the eating window to earlier on in the day will lower obesity risk.”
We recently wrote about how foods packed with good bacteria provide no benefits. Now, new research is dragging yoghurts under the spotlight because of the amount of sugar many contain. In fact, according to the research led by Leeds University in the UK, some yoghurts contain more sugar per 100g than cola. Publishing their findings in the journal BMJ Open, the team of researchers said that even organic yoghurts often contain way too much sugar. The only yoghurts, they said, that can be considered low in sugar are natural and Greek-style. For the research, the team analysed 900 different yoghurts on sale in supermarkets in the UK. Perhaps unsurprisingly, yoghurt deserts were found to contain the most sugar (an average of 16.4g per 100g). More surprising, though, are the findings relating to organic yoghurts. That’s because many people see them as a healthy option, not knowing they contain so much sugar. The UK government are trying to reduce the amount of sugar consumed by the public and yoghurts are one of the areas they want to see addressed. This new research underlines why. To be classed as ‘low sugar’ a product needs to contain no more than 5g of sugar per 100g. Just 9% of the yoghurts studied were found to be below this threshold. Dr Bernadette Moore, lead researcher of the study, said: “I think people, including parents, will be surprised to know just how much sugar there is in yoghurt. “My advice would be to buy natural yoghurt and mix in your own fruit.”
Children who have TVs in their bedrooms are more likely to be overweight than those who don’t, according to new research. Published in the International Journal of Obesity, the study by scientists from University College London analysed data from more than 12,000 children in the UK. They found that girls in particular were more likely to put on weight the longer they spent watching TV. The scientists found more than 50% of the children had TVs in their bedrooms at the age of seven. Interestingly, girls who had TVs in their bedrooms at the age of seven were 30% more likely to be overweight by the time they were 11, compared to kids who did not have TVs in their bedrooms. For boys, the risk was slightly less at 20%. While the link between TVs and being overweight isn’t fully known, the researchers believe it is due to the children getting less sleep and snacking while they are in front of their TVs. Researcher Dr Anja Heilmann said: "Our study shows there is clear link between having a TV in the bedroom as a young child and being overweight a few years later." The scientists behind the research are now calling for more studies to see if similar patterns exist with laptops and mobile phones.
