Age-Related Decrease in Metabolism

The US Department of Agriculture released data showing that Americans consumed an extra 331 calories a day in 2006 compared to 1978. If that number does not sound like a lot, just look how it quickly adds up. An extra 331 calories per day equals 2,317 calories each week or 120,000 extra calories in a year. This amount of excess food intake translates into roughly 15 pounds of stored body fat! Click to read more

What is not recognized by conventional experts is that maturing humans lose the metabolic capacity to utilize even the limited number of calories they may be ingesting. A young person can eat a reasonable amount of food and efficiently convert these calories into energy with minimal residual fat storage. As that same person ages, they suffer a multitude of changes that impact body weight regulation such as hormone imbalance, insulin insensitivity, mitochondrial dysfunction, and decline in resting energy expenditure.
This means that even if we don’t consume a single calorie more at 45 years old compared to our food energy consumption at 25 years old, our aging physiology predisposes us to weight gain.
An understanding of the mechanisms involved in excess fat storage reveals why the advice to “just eat less” is doomed to fail over the long term.

The Age-Related Decrease in Cellular Energy Expenditure

We know that one factor involved in age-related weight gain is a decrease in resting energy expenditure at the cellular level. What this means in simple terms is that we are not burning fat as energy and instead are storing it in our adipocytes (fat cells).
Scientists have found that the decrease in energy expenditure with aging may cause 120-190 excess calories to be stored in the body every day. This translates to an extra 13-20 pounds of stored body fat each year.
Good news is that, we have to means to reduce the effect of age-related decrease in cellular energy expenditure.
