Keto vs. Mittelmeer vs. fettarm: Während sich die Leberinsulinsensitivität bei allen Diäten verbesserte, war der Anstieg bei Keto zwei- bis dreimal höher. Keto verzeichnete den höchsten Rückgang des Leberfetts (67 % Reduktion gegenüber 45 % bei den anderen beiden). 50 % der Keto-Diäter erlebten eine Prädiabetes-Remission, im Vergleich zu 29 % der Mittelmeerdiät und nur 7 % der Personen, die sich fettarm ernährten.

**Keto vs Mediterranean vs Low-Fat? New Study Reveals The Healthiest Weight Loss Diet**
In a new study published in [*Cell Metabolism*](https://doi.org/10.1016/j.cmet.2026.07.020), scientists set out to find which of three popular diets commonly recommended for obesity might pack the biggest punch for improving [overall metabolic health](https://www.sciencealert.com/massive-study-links-the-time-you-eat-breakfast-to-how-long-youll-live).
By that measure, all the diets worked, and all the participants hit their 10 percent weight-loss target.
But in terms of metabolic health improvements, blood samples and other tests showed that one diet stood out as best overall, particularly with regard to liver health markers.
While liver insulin sensitivity improved in all groups, the increase was two to three times greater among the keto dieters, who also saw the highest drops in liver fat (a 67 percent reduction, compared to 45 percent for both the other diets).
Even more pronounced was the keto diet’s effect on prediabetes.
Half the keto dieters in the study ended up going into prediabetes remission, compared to 29 percent of participants on the Mediterranean diet, and just 7 percent of the low-fat group.
While the researchers expected weight loss to deliver improvements in insulin sensitivity and to lower levels of liver fat, even they didn’t expect the keto diet group to see such remarkable effects.
Especially since 73 percent of the calories consumed in the keto diet came from fats, far outstripping the 35 percent and 15 percent levels for the Mediterranean and low-fat diets, respectively.

2 to 3x greater means 3 to 4x as much.
Keto haters in shambles
Okay, now show me a lab report of lipids for the Keto group. Likely trading off prediabetes for heart disease.
Also, I don’t really understand why the researchers were so blown away by the affect on blood sugar. This is a well documented positive of an ultra-low carb diet.
Okay so the diet containing the least carbohydrates most improved insulin sensitivity. That is to be expected right? I’m not sure if these diets were compared before, but the benefits of keto on diabetes were already known and this result can hardly be surprising looking at the development of the disease.
I thought it was fairly known that Keto is an extremely effective interim diet. Doubly so for people with specific problems such as diabetes, fatty livers, and so on. But the Mediterranean diet is much more of a lifestyle choice versus a diet you hop on to reach a goal. You wouldn’t want to do keto for the ensuing decades of your life because you’d be missing out on a good amount of nutrition; it’s more of a tool to assuage your chronic ailments and get you in a better place ASAP. Whereas the Mediterranean is more of a longstanding regimen that features nutritious and satiating foods that help you live a more complete life whereby you consume a wider breadth of fruits, veggies, and grains. This by extension means consuming many more vitamins and minerals (and fiber) across your life.
Difference is with a Mediterranean diet you can live healthy your whole life, with a keto diet you’ll struggle with deficiencies if you keep it for too long.
it might be better to do keto for a year then go back to mediterranean if you have these chronic illnesses
Where’s our favorite meat hater when you need him!? @u/effigymcgee come to the rescue!
We need a 4th. Vs GLP1s
The problem is keto really has to be strictly maintained. I know too many people that are „keto“ then have cheat days at the weekend. Which then turns the diet into a super unhealthy one. It’s either all or nothing for the duration of the diet. Either you stay keto for a period of time, or just do another diet, cut calories instead if you want an occasional cheat day.
There are a slew of negative impacts from a keto diet that is high in animal fat and protien.
Sure I could lose 35 lbs if I cut my leg off, but then id be hoping around on one leg. Almost like the keto diet arguments, except at least I have a leg to stand on.
The best diet is the one you can stick to. Msny people who started keto came off complex carbohydrates (processed foods). I switched whole foods like sweet potatoes, little yellow potatoes, ribs and eat them plain. I don’t eat a ton, but even having these in small amounts a day and some cheat meals on weekends I improved my blood work.
People maybe aren’t attuned to the fact that a primary function of the liver is fundamentally a carbohydrate storage and processing depot.
The liver can’t regulate blood sugar very well when it is supersaturated with carbohydrates. When you burn off the carbs without replacing them, magically the liver cane move carbohydrates into and out of the bloodstream in response to hormones and fluctuations in the sugar concentrations of the systemic and portal bloodflow again.
