What We Think We Know About Metabolism May Be Wrong - GM Newshub

Everyone knows conventional wisdom about metabolism: People put pounds on year after year from their 20s onward because their metabolisms slow down, especially around middle age. Women have slower metabolisms than men. That’s why they have a harder time controlling their weight. Menopause only...

All wrong, according to a paper published Thursday in Science. Using data from nearly 6,500 people, ranging in age from 8 days to 95 years, researchers discovered that there are four distinct periods of life, as far as metabolism goes. They also found that there are no real differences between the metabolic rates of men and women after controlling for other factors

“It was really clear that we didn’t have a good handle on how body size affects metabolism or how aging affects metabolism,” Dr. Pontzer said. “These are basic fundamental things you’d think would have been answered 100 years ago.”

• There’s infancy, up until age 1, when calorie burning is at its peak, accelerating until it is 50 percent above the adult rate.
• Then, from age 1 to about age 20, metabolism gradually slows by about 3 percent a year.
• From age 20 to 60, it holds steady.
• And, after age 60, it declines by about 0.7 percent a year.

Once the researchers controlled for body size and the amount of muscle people have, they also found no differences between men and women.
--------------------------------

The no change at 40 to 60 surprises me some even though we are a lot less physically active at those ages.

Still no answer for the crazy metabolisms some people have until their 20s (where they can literally stuff anything and be sedentary and not gain weight). A few older people have that also. The study does say their is a +/- 25% metabolic rate between people.

Part of it is flat out genetics. Calories in, calories burned......it's a little more complicated on the latter part. It's an interesting subject, and one that fuels an entire industry, including charlatans.

A big part of gaining weight is insulin spikes I think. You can eat the same amount of calories of food that doesn't have all the processed carbs in it and not gain weight like you will eating that stuff.

Thyroid problems are an issue as well. Had an ex girl friend with that problem. She had more dramatic weight fluctuations than Oprah Winfrey. A real shame because she was beautiful.

Selenium and iodine deficiencies in the modern diet cause a lot of that but doctors wont tell people that and instead just throw them on synthetic stuff. Hypo thyroid is a huge problem in this country.

Energy levels and aches and pains also hit the older crowd, reducing both casual and intentional exercise

ask me how I know

If you have hypo thyroid start taking kelp pills for iodine and selenium and I bet you can be weaned off of it. You don't take selenium every day like the bottle has it. Depending on the amount in the pill every other day or every 3rd day is enough. As far as kelp pills for iodine take like 10 pills off the bat (if you are low your body usually lets you know from the feeling of your thyroid taking up so much because its deficient) then 2 pills a day after that. Those crazy iodine amounts some people take is crazy and I would never do that.

I am allergic to iodine (which is in seafood). I stick to bud-light.
