You may have heard the claim that "fat cells form during childhood and puberty and stay forever" before, right? Well, if that's the case it would be logical to assume that our childhood may be a critical developmental windows in which we have the time-limited opportunity to shape or help shape our own or our kids body composition for the rest of our or their lives. Scientists from Mater Health Services South Brisbane,  the University College of London,  and the  Griffith University  have now reviewed the relatively scarce experimental and abundant observational pertinent research in order to examine "the role of physical activity during periods of risk to reduce the probability of obesity onset and maintenance in adulthood" (Street. 2015). Reduced obese individuals and other things...

According to a paper that's been published ahead of print in the journal Public Health and Nutrition , the NHANES data from 1971-2004 clearly shows that the BMI of the average US citizen has risen by ~3pts over this 13-year period and if the trend continued in the years after, we should by now be hovering 4-5pts higher than in 1971-1974, when a BMI of 25.58 kg/m² for men and 25.01 kg/m² for women was the norm. Let's take a look at data I am actually not sure where to start with my detailed recapitulation of the data, but I guess there is no direct causal relationshipp ...
