According to a study published by the scientists Hans-Ulrich Haring, Norbert Stefan and Fritz Schick from the University Hospital in Tubingen, lean people who have an unhealthy metabolism have a 300% higher chance to die when they were compared to healthy people of the same BMI bracket.
This is compared to a small proportion of some people who are obese, but despite their high BMI, they’re metabolically healthy. These scientists managed to prove that the risk of death for this group of people was only 25% higher.
They had 981 volunteers for all BMI divisions. They were all checked for the standard tests.
Those who had the results that exceeded 2 of the safe maximum readings were clinically unhealthy. There were 18% of people who were in the normal BMI range.
Other tests included using a spectroscopy and functional magnetic resonance imaging, but also blood tests which presented the distribution of fats around the body of the participant as well as their fat mass, their blood vessel thickness, insulin sensitivity and fat deposits on the liver.
In the patients who were obese, the nonalcoholic fatty liver disease as well as the abdominal fat levels could show that there was a presence of metabolic syndrome. In the lean people, skinny lower legs were the ones that showed the presence of poor metabolic health.
Thin legs were usually an indicator that there is a difficulty derived from the genes that can’t store fats in the lower limbs and is also connected to a higher risk of poor cardiovascular health.
There were also numerous similarities between the body-shape and the phenotype as well as people with some rare disorders like lipodystrophy (the body can’t sustain adequate reserves of fat) and unhealthy normal BMI cohort.
This condition can appear in numerous people, but it mostly appears in people who have HIV.
Other researches show that people who had one of the most common types of chronic liver malfunction otherwise known as non-alcoholic fatty liver disease (NAFLD) and were obese and those who were with normal weight had clear differences in their metabolism. Still, this is yet to be researched.
