[Ed. – A study suggests that people who eat and exercise the same in today’s conditions are 10% heavier than people in the 1980s. The emphasis on microbiomes is interesting, but I’d also like to see attention to all the various influences that reportedly suppress thyroid performance, from sunscreens, and fluoride in the water, to antibiotic ingredients in soap products and radio waves from cellular communications and smart meters. Any one of those environmental influences is probably not decisive in itself, but most people in America are now subjected constantly to ALL of them, and more.]
A study published recently in the journal Obesity Research & Clinical Practicefound that it’s harder for adults today to maintain the same weight as those 20 to 30 years ago did, even at the same levels of food intake and exercise.
The authors examined the dietary data of 36,400 Americans between 1971 and 2008 and the physical activity data of 14,419 people between 1988 and 2006. They grouped the data sets together by the amount of food and activity, age, and BMI.
They found a very surprising correlation: A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher. In other words, people today are about 10 percent heavier than people were in the 1980s, even if they follow the exact same diet and exercise plans.
