Making big fat cells smaller by eating less, moving more, or having weight-loss surgery helps fat cells work better and improves your health.
Descriptive
When fat cells get too big, they don't work well and the body tries to stop them from growing further to avoid damage and swelling.
When your body has extra energy, it stores it in fat cells by making the cells bigger or making more of them.
One in three of these students had thoughts of ending their life — a rate higher than seen in many other war-affected groups, meaning universities need to act fast to prevent suicide.
At first, students felt worse — then they got a little better in 2023 — but by 2024, they felt even worse than before. This means they didn’t just get used to the war — their mental health got worse again.
No matter when they were surveyed, students who were more afraid of the war were also more emotionally drained — this connection stayed strong throughout the war.
Correlational
Where students were living during the war mattered more for their emotional exhaustion than how long the war had been going on — being forced to move hurt more than just the passage of time.
Quantitative
When students are both scared of the war and feel lonely or depressed, their burnout gets much worse — it’s not just the sum of each stressor, but a combined effect.
In 2023, students felt less emotionally drained — but by 2024, they were burned out again, even more than before.
Students who were more depressed also had much higher levels of fear and emotional exhaustion — the worse their depression, the worse their fear and burnout.
Almost 1 in 3 of these students had thoughts about ending their life in the past month — and those without religious beliefs were much more likely to have these thoughts than those with religious beliefs.
Students who were in a relationship felt less alone emotionally and overall than those who weren’t, hinting that having a partner might help reduce feelings of isolation during the war.
Students who don’t follow a religion reported feeling more depressed, more drained, and lonelier than those who did have religious beliefs.
The more lonely these students feel — especially emotionally — the more depressed and burned out they tend to be. Their depression is the biggest factor linked to how lonely they feel.
In 2022, these students were the most depressed. In 2023, their depression got better — but by 2024, it got worse again, almost back to where it started.
Students who had to flee their homes or were forced to move within Ukraine felt more emotionally drained and more afraid of the war than those who stayed put.
In 2022, these students were really scared of the war. By 2023, they felt a bit less scared — but by 2024, their fear shot back up again, even higher than before.
When these young women feel more depressed, they also tend to feel more scared of the war, more emotionally drained, and more alone — and their depression is the biggest factor linked to feeling burned out.
Where in the liver insulin resistance happens determines whether it causes high blood sugar, high fat, or neither.
The front part of the liver needs insulin to handle sugar properly when eating a high-fat diet—without it, blood sugar rises.
Mechanistic
Insulin signals in the back part of the liver help fat build up there when the mouse eats a high-fat diet.
When insulin doesn’t work in the back part of the liver, the body doesn’t respond by making more insulin—even though fat in the liver goes down.
Even if you block insulin in the front part of the liver, the mouse still gets high blood sugar when eating a high-fat diet.
When mice eat a high-fat diet, fat builds up in both parts of the liver—but blocking insulin in just one part stops fat from building up there.
