Age When Metabolism Starts To Slow Down And 4 Factors That Influence It

Date November 28, 2017

What is metabolism and when does it start to slow down?

It’s common knowledge that as you age, it becomes easier to gain extra pounds and much harder to lose them. That’s because your metabolism becomes slower, which is in part a normal sign of getting older but can also be influenced by factors other than age.

Metabolism is a combination of chemical processes in your body by which it converts nutrients into energy, builds tissue, and gets rid of waste. How fast you burn calories depends on your metabolic rate. Our metabolic rates are at their highest when we are teenagers because adolescence is the period when your body grows actively and needs more calories. This is why many teens can munch on whatever is at hand and stay fit without much effort. People in their 20s are usually quite active, and their weight tends to remain stable.

According to Peter LePort, MD, medical director of the MemorialCare Center for Obesity at Orange Coast Memorial Medical Center in Southern California, the slowdown in metabolism becomes more significant and noticeable after you hit 30.

He told Yahoo Health:

It’s usually after the age of 30, but most people really notice it around 40.

Many women around this age have similar lifestyles (work, eating habits, etc.). And even if they care about their health, they don't pay attention to some important factors and make mistakes, which can slow down their metabolism.

Why exactly does metabolism slow down with age?

Factors that make your metabolic rate slower as you age include:

  1. Decreased physical activity;
  2. Muscle loss (also known as ‘sacropenia’), which is a gradual process that starts after age 30 and happens faster without exercise;
  3. Hormone changes – a decline in the production of growth hormone and sex hormones – estrogen in women and testosterone in men;
  4. Mitochondria (parts of the cell that produce energy) becoming less efficient.

There’s nothing you can do about your mitochondria, and the decline in hormones can be slowed down to some extent but is inevitable.

But other factors can be successfully controlled with lifestyle changes, such as exercising regularly and eating a balanced diet.
