In women, a higher amount of a specific enzyme called H6PDH in the fat around the organs is linked to having less body fat overall.

Correlational

Researchers looked at several genes related to stress hormones in fat tissue from women's bellies. They found that only one specific gene (11β-HSD1) in the omental fat was linked to belly fat obesity in women, even after accounting for other factors that might affect the results.

Correlational

In women who have fat stored around their internal organs (visceral obesity), the fat tissue produces more of a specific enzyme and hormone related to stress compared to women without this type of fat buildup.

Correlational

Scientists found that the activity of a specific gene (11β-HSD1) in belly fat can help predict how much belly fat a woman has, even after accounting for her total body fat, age, and whether she's gone through menopause.

Correlational

In women, higher levels of a specific enzyme (11β-HSD1) in fat tissue are linked to having more body fat, especially around the belly.

Correlational

Doctors found that fat around the organs in women's bellies has more of certain proteins that handle stress hormones compared to the fat under the skin.

Quantitative

Scientists looked at two types of fat in lean Chinese adults - belly fat and fat under the skin - and found that certain genes involved in inflammation and stress response are less active in the belly fat.

Descriptive

In fat tissue from Chinese adults, higher levels of a specific receptor that responds to stress hormones are linked to higher levels of a receptor that triggers inflammation. They're connected in a way that when one goes up, the other tends to go up too.

Correlational

In Chinese adults, people with higher levels of a specific enzyme (11beta-HSD1) in their belly fat tend to also have higher body weight, as measured by BMI.

Correlational

In adults with obesity from China, a gene called TLR4 that helps control inflammation is more active in fat stored deep inside the belly around organs than in fat found just under the skin.

Descriptive

In people with obesity from China, the genes that make a specific inflammatory marker called TNF-alpha are more active in the fat around the organs inside the belly than in the fat under the skin.

Descriptive

In Chinese adults, the gene that makes the hunger-controlling hormone leptin is less active in fat stored around the organs inside the belly compared to fat stored under the skin, whether someone is lean or obese.

Descriptive

A compound found in hops called 8-prenylnaringenin can act like the hormone estrogen in the body. It might attach to estrogen receptors and could potentially cause fat to build up around the belly area.

Mechanistic

When estrogen levels are out of balance, the body starts storing fat in the wrong places—instead of the harmless fat under the skin, it gets stored in the dangerous fat around internal organs.

Mechanistic

When someone has too much cortisol (the stress hormone) in their body, like in Cushing syndrome, the fat builds up in the belly area but disappears from arms and legs, giving them a distinctive body shape with a big belly and skinny limbs.

Descriptive

Fat cells found deeper in the belly (visceral) have more cortisol receptors than fat cells under the skin (subcutaneous), so they respond more strongly to the stress hormone cortisol by taking in more fat and growing faster.

Mechanistic

When someone has too much insulin in their blood for a long time, it blocks the brain's ability to respond to leptin - the hormone that tells us we're full - so the person keeps feeling hungry and eating even though their body already has enough energy stored.

Mechanistic

This is a theory about how fat storage works in the body. It says there's a limit to how much fat subcutaneous fat cells (the fat under your skin) can hold. Once they're full, any extra fat gets stored in more dangerous places like belly fat and the liver.

Descriptive

When someone has too much insulin in their blood, it stops the body from burning stored fat and instead makes the body turn extra sugar into new fat, which gets stored in fat tissue.

Mechanistic

When the body has too much insulin floating around for too long, cells stop listening to it to protect themselves from damage. This forces the pancreas to pump out even more insulin, creating a harmful cycle.

Mechanistic

Your body has special hormones that control where fat gets stored. When these hormones get out of balance, you end up storing more fat deep inside your belly around your organs.

Mechanistic

The fat stored around your internal organs is like a factory that constantly pumps out inflammatory chemicals. These chemicals cause widespread inflammation in your body, make your cells age faster, damage your heart and blood vessels, and even weaken your body's ability to fight cancer cells.

Mechanistic

Scientists say there's not enough good quality research on how the keto diet affects brain diseases - the studies are small, short, and all different from each other, making it hard to draw clear conclusions.

Descriptive

Scientists have found that in lab studies with cells and animals, a very high-fat, very low-carb diet (called ketogenic) seems to change how brain cells work—affecting their energy production, inflammation levels, and even how the gut talks to the brain. But we don't know yet if this works the same way in humans.
