When mice with fatty liver disease eat a special diet with certain proteins, it changes how their cells produce energy, making some parts work harder and others slower, which might stress their energy factories.

Correlational

When mice with fatty liver disease eat a special low-carb diet with certain amino acids, their livers make 30-50% less new fat compared to mice eating high-fat food.

Quantitative

In mice with fatty liver disease, a special diet with certain nutrients and less carbs seems to boost the liver's ability to make ketones, which are energy molecules. This diet made ketone production about 50-100% higher than just a high-fat diet.

Correlational

For overweight people with a fatty liver condition not caused by alcohol, eating fewer carbs and calories might lower some fat levels in their blood, but it doesn't seem to change other cholesterol or sugar levels much, according to a small study.

Correlational

When overweight people with fatty liver disease eat fewer carbs and calories, they lose weight and belly fat, but their body's ability to handle sugar doesn't really change.

Correlational

In overweight adults with fatty liver disease, the more fat there is in the liver, the more sugar the liver tends to make, and this link is pretty strong even when considering other factors like body size.

Correlational

For overweight people with fatty liver disease not caused by alcohol, eating fewer carbs and calories helps their liver handle sugar better by 22%, based on a small test group.

Correlational

For overweight people with a fatty liver condition, following a very low-carb, low-calorie diet for 8 weeks can cut down the fat in their liver by about two-thirds.

Causal

Animal studies about cholesterol are misleading because different animals react very differently - some get sick easily while others need huge amounts to be affected, making them poor models for human dietary advice.

Descriptive

Limiting cholesterol in your diet might be bad for health because it could cut down on important nutrients like choline, which helps babies' brains grow properly during pregnancy. Not getting enough choline might raise the chance of birth defects.

Causal

Eating eggs every day doesn't raise your chances of heart disease or stroke, according to a big review of health studies.

Correlational

Eating foods with cholesterol doesn't really affect your chances of getting heart disease, according to many big studies over many years.

Correlational

Eating more cholesterol raises both 'bad' and 'good' cholesterol a little bit, but doesn't change their ratio much, which is important for heart health.

Quantitative

Eating fewer calories might help lower the chance of breast cancer in women by changing how hormones and body processes work, and doing this along with exercise could be a good way to prevent it.

Causal

Eating fewer calories might help women with a health condition called PCOS by lowering certain hormone levels, making their bodies respond better to sugar, and helping them have regular periods.

Causal

When pregnant mammals don't get enough food, their babies grow slower inside the womb because they don't get enough nutrients and the placenta doesn't work right. This can lead to health problems for the babies later in life.

Causal

Eating fewer calories helps older female mice have healthier eggs by boosting a protein called SIRT3, reducing cell damage, and preventing egg division problems, which makes babies more likely to survive.

Mechanistic

Eating less food might help female mice keep more of their egg cells for longer by slowing down certain processes in their bodies, which could let them have babies later in life.

Mechanistic

When female mammals eat less food, it can slow down when they start puberty. This happens because their brain makes less of a special protein and turns on a signal that puts the brakes on growing up reproductively.

Mechanistic

When female animals eat less food, it makes it harder for them to have babies because their bodies stop sending the right signals for egg release.

Mechanistic

Researchers found that when they put middle-aged male rats on a diet with 15% or 35% fewer calories, it helped their reproductive health at first. But after a year on the diet, these benefits went away, and only one-third of the dieting rats still showed normal mating behavior compared to all of them at six months.

Descriptive

When older male rats eat less food for several months, their bodies process sugar better and have healthier hormone levels.

Correlational

When male rats ate less food for several months, their testicles showed fewer signs of cell death compared to rats that ate normally. This was measured using a special light test that detects dying cells.

Correlational

Eating less food for six months helped older male rats have better swimming sperm, and this improvement lasted for a year compared to rats that ate normally.
