Some people with Crohn’s or ulcerative colitis who eat only meat get better and can stop taking some of their meds, feeling much better overall.

If you're eating only meat on a carnivore diet, you're probably getting almost no fiber and missing key vitamins and minerals like vitamin C and potassium, which could put your health at risk over time.

People on a meat-only diet for up to a few years tend to see their 'bad' and total cholesterol go up a lot, which might raise their risk of heart problems.

People with inflammatory bowel disease who eat only animal products for several months to years might see less inflammation in their bodies, based on lower levels of key inflammation markers in their blood and stool.

People on a meat-only diet for months say they feel healthier, more full, sleep better, and have more energy and mental clarity — and most say they do it for health reasons, even though science hasn't fully proven these benefits.

If adults get 5% more of their daily calories from healthy fats like those in olive oil or avocados, they might have a slightly lower chance of dying from any cause over time.

Eating too much saturated fat might increase your risk of dying from any cause, especially cancer — the more you eat (up to a point), the higher the risk, according to big studies that followed people for years.

Even a tiny bit more trans fat in your diet — just 1% of your daily calories — could raise your chances of dying from heart disease or other serious illnesses by 6%.

Eating a bit more healthy fats like those in nuts and fish—replacing things like carbs or saturated fats—might help people live longer and lower their chances of dying from heart disease or cancer.

If a middle-aged person has higher 'bad' cholesterol, they're more likely to have buildup in their heart arteries — every 38.7-point rise means about a 17% higher chance of early heart disease signs, even if they already have symptoms.

If you have calcium buildup in your heart's arteries, the link between your 'bad' cholesterol and heart problems changes — it’s stronger or weaker depending on that calcium.

If a middle-aged person has heart symptoms but no calcium buildup in their arteries, things like diabetes, smoking, and low 'good' cholesterol are linked to future heart problems — but their 'bad' cholesterol level doesn’t seem to matter, which might mean other non-plaque-related issues are causing the heart trouble.

If you're a middle-aged person with signs of heart disease and calcium in your arteries, having very high 'bad' cholesterol makes your risk of heart problems more than double. But if your arteries are clean, even sky-high cholesterol doesn’t seem to increase your risk.

If you're a middle-aged person with symptoms, having higher 'bad' cholesterol (LDL) means you're more likely to have heart problems over the next four years — but only if scans show you already have plaque in your heart arteries.

If you're overweight and your kidneys are working too hard at the start, going on a high-protein diet to lose weight might make your kidney function look more normal—not worse—by bringing down their overactivity.

People who are overweight or obese can lose about 14.5 kg in around 8 months on a high-protein, low-carb diet, mostly from fat, while even gaining a little muscle.

If you're an adult who's overweight and has mild kidney disease, losing weight on a high-protein diet might actually help your kidneys a little over 8 months — even if you eat up to 1 gram of protein per pound of body weight each day.

If you're overweight or obese and on a high-protein diet to lose weight, your kidneys stay just as healthy — or may even get a little better — even if you already have mild kidney issues, high blood pressure, or type 2 diabetes.

Doctors who see more patients each year are more likely to like the idea of getting paid extra for good care — and they also prefer sharing those bonuses with their patients.

Giving bonus money only to doctors or only to patients doesn’t help lower cholesterol more than not giving any bonuses at all.

Most doctors who treat patients at high risk for heart problems think it's fair to offer money rewards to both doctors and patients to encourage better care — and their opinions don’t change even after being in such a program for a year.

Most doctors think it's fair to split bonus money with their patients when both work together to improve health, like lowering cholesterol.

Doctors who liked the idea of giving money rewards to themselves or their patients for staying healthy saw bigger drops in their patients' bad cholesterol, especially when both doctor and patient got rewards.

Older people with higher 'bad' cholesterol might actually live just as long or longer than those with lower levels, and having very low cholesterol could be risky — especially if you're elderly and have diabetes or a genetic form of high cholesterol.
