It's My Metabolism

Scott LaFee on

Our daily energy expenditure, otherwise known as our metabolism, changes over the course of our lives. A slower metabolism is often credited (blamed) for why we put on weight in later life, especially women.

As it turns out, while metabolism does change over time, it doesn't necessarily do it in the way we thought. New research shows distinct life stages. In the first, total energy expenditure revs up rapidly in newborns to roughly 50% more than adult levels at age 1 and then slowly declines to adult levels around age 20, where it remains stable (even during pregnancy) until age 60.

At 60, metabolic rates begin to decline again, gradually. And once other factors are accounted for, the metabolic rates of men and women were determined to be pretty much the same.

The Heat Is On

Heated tobacco products may be the next big thing among teens. HTPs aren't traditional cigarettes and they aren't e-cigarettes, which use a heating element to vaporize nicotine-containing liquids. Rather, HTPs heat actual tobacco leaves to release compounds. A survey of teens in California found that while HTPs were not yet widely marketed, 10% of high schoolers had already heard of them.
