Why Your Metabolism Slows Down With Age

You’ve probably been told that as you age, you can’t eat like your younger self.

That’s because your metabolism tends to slow with age, making it easier to add a few extra pounds and harder to lose them.

A few reasons for this include muscle loss, being less active and the natural aging of your metabolic processes.

Luckily, there are many things you can do to combat this age-related drop in metabolism.

This article explains why your metabolism slows down with age and what you can do about it.

What Is Your Metabolism?

Simply put, your metabolism is all of the chemical reactions that help keep your body alive.

It also determines how many calories you burn per day. The faster your metabolism, the more calories you burn.

The speed of your metabolism is influenced by four key factors (1):

Resting metabolic rate (RMR): How many calories you burn while you are resting or asleep. It is the least amount needed to keep you alive and functioning.

Thermic effect of food (TEF): How many calories you burn through digesting and absorbing food. TEF is usually 10% of your daily calories burned.

Exercise: How many calories you burn through exercise.

Non-exercise activity thermogenesis (NEAT): How many calories you burn through non-exercise activities, such as standing, fidgeting, washing the dishes and other household chores.

Other things that can affect your metabolism include age, height, muscle mass and hormonal factors (1).

Unfortunately, research shows that your metabolism slows down with age. A few reasons for this include less activity, muscle loss and the aging of your internal components (2, 3).
