While other primates have less than 9% body fat, a healthy range for humans is anywhere from 14% to 31%.
Using a technique called ATAC-seq, they scanned each species' genome for differences in how their fat cell DNA is packaged.
Normally most of the DNA within a cell is condensed into coils and loops and tightly wound around proteins, such that only certain DNA regions are loosely packed enough to be accessible to the cellular machinery that turns genes on and off.
The researchers identified roughly 780 DNA regions that were accessible in chimps and macaques, but had become more bunched up in humans. Examining these regions in detail, the team also noticed a recurring snippet of DNA that helps convert fat from one cell type to another.
Not all fat is created equal... Most fat is made up of calorie-storing white fat. It's what makes up the marbling in a steak and builds up around our waistlines.
Specialized fat cells called beige and brown fat, on the other hand, can burn calories rather than store them to generate heat and keep us warm.
One of the reasons we're so fat, the research suggests, is because the regions of the genome that help turn white fat to brown were essentially locked up...in humans but not in chimps.
Humans, like chimps, need fat to cushion vital organs, insulate us from the cold, and buffer us from starvation. But early humans may have needed to plump up for another reason, the researchers sayas an additional source of energy to fuel our growing, hungry brains.
The human brain uses more energy, pound for pound, than any other tissue. Steering fat cells toward calorie-storing white fat rather than calorie-burning brown fat, the thinking goes, would have given our ancestors a survival advantage.

Did any of them involve a jerk store?
How many other primates are cooking their meat?
Stupid premise from the start, IMO.
We learned to make any kind of food available any time of year.....then we ate it.
Oh yeah, we ate it.
High Fructose Corn Syrup.
Most people weren't fat when foods contained actual sugar.
Right. Animals can have the best genes in the world, but if they adopt a modern human lifestyle, they’ll get obese just like us.
Wouldn’t that make goats and bunnies fat?
In a word, bacon.
Nutella, white peopls’s Kryptonite.
If goats and bunnies had sentience and free will, with a dose of Original Sin, absolutely.
Brains. The smarter the easier the lazier the fatter.
um- have ya seen primates? Many have ‘beer guts’ times 10
Our intelligence ... it allows us to make fatteni g items that donot occur in nature.
I was going to say SNAP!!!!
Lately in the 15 or less aisle, they are buying up the snacks for summer days!! Mom’s are larger than size 12 and in their 20’s... The last two times I went to the grocery, I have had THREE mothers buying SNAP snacks- loaded with sugar and carbs. Last one got into a nice pick up truck that was about 4 years old. We have to wait to buy a truck so they can eat...think about that!!!
babies have more. body-fat than grown-ups, and their brains are very actively developing.
Reminds me of a picture I saw of Thomas Edison next to Geronimo, as grown men. The latter was lean, hard, fully developed, and confident. Edison, was soft, pale, and had the open look of an innocent baby. Modern people who learn a lot throughout life are more like Edison, the softy, than Geronimo, the manly man. It doesn’t make a man look very handsome, but it made Edison pretty wealthy, iirc.
“unless we become like little children, we will not see the Kingdom of God.”
The ability to grill. And chips and salsa
The human fat gene looks just like a Cheeto.
There are 10 types of people in the world. Those who understand binary and those who don’t. gr8eman is the latter kind.
Or a krispy kreme.
