A new study in Science explodes almost everything we thought we knew about age and metabolism.
One of the most comprehensive studies on metabolism ever conducted, it involved over 80 researchers, took over 40 years, and studied data from 6,500 people between the ages of eight days old and 95 years.
The first thing the study blew away was the conventional understanding that men always burn more calories than do women — the study found no calorie-burning differences in the sexes, after accounting for other factors.
The second thing the study deep-sixed was the accepted wisdom that we will all see a slow-down in energy levels, especially with the start of pre-menopause in the 40s. One of the authors was quoted as saying, ‘We just didn’t see that.”
The study found that infants up to one year old have the fastest metabolisms — approximately 50% faster than adults. After age 1, metabolism “declines slowly to adult levels” until age 20. From age 20 to 60, our metabolism “remains stable.” Only after age 60 does our metabolism slowly start to decline by about 20% until age 95.
Not only do these findings give us hope — we’re not as chained to our hormones and biological clock as we once thought — they also call on us to think back to those times in our life when we believed our metabolism just slowed down on its own.
It could be that work or family responsibilities pulled us away from being more active.
No matter what, though, the great news is that — whatever the cause of our metabolism not being as primed as we want it to be — with the right diet hacks, along with a bit more physical activity, we can power up our metabolism again, regardless of what decade of life we find ourselves in!
