How do I lose a
pound?
For many years we were told that
you if you consumed 3500 calories less each week you would lose 1 pound every
week. That meant, eating 500 calories less each day and you would lose one
pound every week.
Or if we exercised to expend 3500
calories more each week we would lose a pound that way.
Many dietitians and doctors still
use those estimates.
Well it turns out those estimates
are frequently way off.
One reason for the inaccuracy of
those estimates is that our metabolism changes as we lose weight. Lots of
things change over time. Our bodies are not static; they are dynamic.
Now sophisticated mathematical models allow for more accurate estimates of body weight changes with changes in
calorie intake or physical activity.
These dynamic models factor in changes
in our metabolism as weight is lost.
The previous static models failed
to do so.
Much of this is the work of physicist Kevin Hall .
Dr. Hall received the Lilly
Scientific Achievement Award at the annual scientific meeting of The Obesity Society this year.
Dr. Hall’s dynamic model showed
that a 20% tax on sugar-sweetened beverages would lead to a trivial amount of weight loss. A static model vastly overestimates the weight that would be lost.
