Why do your metabolism slow down as you get older?

[Anonymous]

I think because kids grow and adults don’t grow anymore.

Because you're slowly dying in simple terms.

All the way through puberty your body is producing growth hormones to increase your mass to make you big and strong you need calories to fuel that. But at some point that stops and you're a fully grown adult. Now at that point you just need "x" amount of calories to maintain your weight and health and any excess just get stored for the future fuel. In a evolutionary sense human beings have not had as much access to calories as now. In the past we had to store calories in the form of fat to fuel us during times of famine. So the avg. Modern human overeat as we eat for enjoyment almost as much for sustenance. Finally at some point about around 30 your BEGINS to degrade. Our cellular structure is designed to degrade. I actually watched a program on this where a leading scientist explained how our bodies were designed on a cellular level that after dividing over and over again it degrades (think of it like taking a photocopy of a photocopy of a photocopy). Each time the copy is made it degrades. Basically the way she explained it as cancerous. That over a long enough time line after a enough copies a cell will turn cancerous. Which is interesting. Because the way I understand it this is the problem science has with trying to grow organs in a lab. It's not hard to program a cell and get it to grow into the organ you want it to. But they have a hard time preventing it from turning cancerous.

Aging is basically a slow process of dying. At best you can delay it by keeping healthy - staying active, eating right, getting good exercise, and maintaining a healthy weight.

You need to keep up your muscle mass which naturally reduces with age. You also need to do cardio, and exercise your lungs to reduce loss of lung capacity. Decreased lung capacity is a major reason why older people die from COVID, flu, etc.

But no matter what you do, you will slow down and eventually die.

On top of all that, most people just don't have as much motivation to be as active as they get older. It's time to kick back and stop being so hyper like when we were young. There is no way in hell I would want to keep up the lifestyle I had when young, even if I was able to.

As you age, metabolism slows down primarily due to decreases in muscle mass, hormonal changes, and lifestyle factors.

The full body checkup comprises examinations such as the Cholesterol total, Complete Blood Count (CBC), Complete urine examination and other assessments.

The Advanced Package like Medicas Wellness Ultimate Full Body Checkup comprises additional tests, including fundamental screenings for health status such as Vitamin Profile, Thyroid Profile, Diabetes Profile, Cardiac Risk Marker, Kidney Profile, Liver Function Tests, and Complete Blood Picture.

As we get older, our bodies tend to have less muscle, and the hormones that affect metabolism change. Also, if we become less active, our metabolism can slow down.
It's essential to stay active and eat well to help keep our metabolism in good shape as we age.

I wasn’t that active as a kid I’m more active as an adult. I swear it is what I eat not if I exercise or not as an adult.

You can counteract it by keeping muscle mass, staying active and healthy.
