They Don't Make Fitness Like They Used To


As if I didn’t already know this. It turns out we have to work even harder than our parents to stay fit.

Published in the journal Obesity Research & Clinical Practice, researchers analyzed National Health and Nutrition Survey dietary and physical activity data from between 1971 and 2008 for more than 36,000 Americans.

They found that the total caloric and carbohydrate intakes increased up to 14 percent, despite a large spike in how often participants were exercising.

The thought is that an increase in exposure to environmental chemicals like pesticides, the use of prescription medications, and a change in the bacteria in American stomachs could all be to blame for the harder fight against obesity. More research will be needed before researchers can explain the changes. (MentalFloss)
