Eating fewer carbs and more protein for a week might help turn off fat-making genes and turn on fat-burning and metabolism genes in the livers of obese people with fatty liver disease.
If you're an obese adult with fatty liver, how much folate is in your blood might help explain how much fat is in your liver — and it could account for nearly 1 in 5 cases, even after considering body weight.
If you're an obese adult with fatty liver disease, switching to a low-carb, higher-protein diet for just two weeks might quickly boost good gut bacteria that make folate—and your blood folate levels could go up in as little as one day.
If you're an obese adult with fatty liver, going on a low-carb diet for just two weeks—even without cutting calories—might slash your liver's fat production by nearly 80% and boost fat burning in your body by almost 5 times.
If you're an obese adult with fatty liver disease, switching to a very low-carb, high-fat diet for just two weeks might cut your liver fat by nearly half—and you could see improvements in as little as one day.
Even when rats eat fewer calories, a keto-like diet can still cause liver problems — like making too much sugar and messing up how the body uses protein — so the weight loss might not be worth the harm.
In rats, eating a diet high in fat and low in carbs changes how the liver handles certain fuels — it makes more sugar from lactate but gets worse at using alanine, especially when fewer calories are eaten.
Rats on a low-carb, high-fat diet have trouble handling sugar—even if they're not eating extra calories—and their insulin seems to be working fine, which is weird because those two things usually go together.
In rats, eating a diet super high in fat and very low in carbs for a month leads to higher blood sugar and more fat in the liver—even if they're not eating too many calories.
If you're overweight and have fatty liver, going on a keto diet for just 6 days might supercharge your liver's energy system and shift it into fat-burning mode, possibly helping your body make more ketones.
If you're overweight and have fatty liver, going on a keto diet for just 6 days might reduce how your liver burns fuel, pushing your body to make more ketones instead.
If you're overweight and have fatty liver, going on a keto diet for just 6 days might make your liver burn fat for fuel way more—like over 3 times as much—instead of storing it.
Even though fat levels in the blood go up, a super low-carb diet for just 6 days seems to dramatically improve how well the liver responds to insulin in people with fatty liver and extra weight — which goes against what doctors usually expect.
If you're overweight and have fatty liver, going on a keto diet for just 6 days might cut the fat in your liver by over a quarter—even if you barely lose any weight.
In Mongolian adults with type 2 diabetes, eating meat affects both ferritin levels and heart disease risk, but ferritin doesn’t seem to be the reason for that link.
In Mongolian adults with type 2 diabetes, high ferritin levels don’t seem to be linked to body-wide inflammation — they might just come from eating a lot of iron-rich foods instead.
If you're a Mongolian adult with type 2 diabetes and have high levels of a protein called ferritin in your blood, you might be at greater risk for heart problems over the next 10 years — and this seems to be true even if your other signs of inflammation are normal.
In Mongolian adults with type 2 diabetes, people with more stored iron in their bodies tend to have higher 'bad' and total cholesterol levels — which might mean how the body stores iron affects cholesterol.
If you're a Mongolian adult with type 2 diabetes and eat a lot of meat, your body might store more iron — and this could be because meat adds extra iron to your system.
Keto diets might boost testosterone in overweight or insulin-resistant guys, but could lower hormone levels in lean guys who aren't eating enough calories.
If lean, active guys follow a keto diet with very few calories for a long time, it might lower key hormones that affect energy and sex drive — even if they're otherwise healthy.
If overweight or obese guys who have trouble using insulin stick to a keto diet for a short time, their testosterone levels might go up — probably because they lose weight, get better at handling sugar, and have less inflammation.
For people with high blood pressure, two body chemicals—endothelin-1 and 8-ISO-PGF2alpha—are better at predicting kidney problems than a common inflammation marker, and endothelin-1 is the most accurate of all.
For people with high blood pressure, a certain blood marker linked to body stress is closely tied to how well their kidneys are working, and a level of 329 in the blood can spot kidney issues with high accuracy.
