"Healthy obesity" turns unhealthy
In recent years, some research has suggested that it’s possible to be both obese and healthy. But now a study by scientists at University College, London debunks that notion, concluding that obesity almost always becomes unhealthy.
Researchers observed 2,500 medically obese people over the span of 20 years with 66 of these people classified as “healthy” obese due to their cholesterol, blood pressure, triglyceride levels, fasting glucose levels, and insulin resistance. At the end of the 20 years, researchers found that more than half of those who began the study as healthy, became unhealthy and the ones who remained healthy did so by losing enough weight to no longer be considered obese.
Researchers then studied another group of healthy obese individuals for 20 years and found similar results – 48 percent became unhealthy, while 10 percent lost enough weight to no longer be considered obese.
The more time passes, the more likely that healthy obese adults will become unhealthy and the progression becomes stronger, lead researcher, Joshua Bell concluded in the report, which was published in the Journal of the American College of Cardiology.

Study suggests people born during solar peaks don't live as long
Being born during a year when there was a lot of solar activity may actually be a factor in how long you live, according to an extensive new study done in Norway.
Researchers analyzed looked at people in Norway over two centuries and compared one group that was born during solar peak years and another born during the lowest solar activity years. They found that people born during solar peaks lived on average 5.2 fewer years compared to the people born during the lowest solar activity years.
The scientists speculated that more solar activity brings UV radiation which affects pregnancies by disrupting regular folic acid and vitamin D levels. This disruption can carry consequences for successful delivery of pregnancies as well as for the adults born during these solar peaks as they might be more susceptible to diseases.
Recent solar peaks include the years 1957, 1968, 1979, 1989, 2000 and 2013 while the recent solar lows include 1954, 1964, 1976, 1986, 1996, 2008.
