In fact, people who are walking up to 15,000 steps are still putting on the pounds, a new study has discovered.

Eating your breakfast 90 minutes later and dinner 90 minutes earlier—and yet still eating as much as you wish between those two times—could help you lose double the body fat as those sticking to usual meal times.

Although there are no restrictions on what or how much you eat, you're dramatically reducing your 'window' when you can eat, and so you're introducing a mini-fast and eating less because you'll be less hungry, say researchers from the University of Surrey.

The products change the children's gut microbiome which helps regulate their weight, new research has discovered. The only safe cleaning agents to use are eco-friendly ones, which don't have the same bad effects.

Infants who live in homes that use standard disinfectants at least once a week were twice as likely to have higher levels of gut microbes, known as Lachnospiraceae, which are linked to weight gain.

Children who were overweight or obese by the time they were three years of age already had changed bacteria in their gut, known as the microbiome, when they were four months old.

Canadian researchers found a direct link between a changed gut microbiome—with a depletion of bacteria such as Haemophilus and Clostridium and an increase of Lachnospiraceae—and the number of times that disinfectants, such as multi-surface cleaners, were used around the home.

The answer could be down to one type of bacteria in the gut, or the lack of it. The bacterium is called Akkermansia muciniphila, and it seems to regulate weight gain and even type 2 diabetes, which often occurs after people start becoming seriously overweight, or obese.
