The Claim

In adults with metabolic dysfunction-associated steatotic liver disease, a 12-week ketogenic diet is associated with a significantly greater reduction in muscle mass compared to a calorie-restricted diet, with a median reduction of 3.0 kg versus 1.8 kg (p < 0.001, Cohen’s d = 0.59).

In plain English

Among adults with metabolic dysfunction-associated steatotic liver disease, a 12-week ketogenic diet results in a median muscle mass loss of 3.0 kg, while a calorie-restricted diet results in a median loss of 1.8 kg.

See the scientific wording

In adults with metabolic dysfunction-associated steatotic liver disease, a 12-week ketogenic diet is associated with significantly greater loss of muscle mass compared to a calorie-restricted diet, with a median reduction of 3.0 kg versus 1.8 kg (p < 0.001, Cohen’s d = 0.59), raising concerns about unintended metabolic consequences despite improvements in liver fat.

Why this might work

When the body runs out of carbs, it starts breaking down muscle to get amino acids. These amino acids are sent to the liver, where they are turned into glucose and ketones to fuel the brain and organs. This process pulls protein out of muscles, causing them to shrink, even when total weight loss is the same as with other diets.

  1. Study: The effects of ketogenic diet and calorie-restricted diet on metabolic dysfunction-associated steatotic liver disease: a retrospective study

    People with fatty liver who ate a keto diet for 12 weeks lost more muscle than those on a regular low-calorie diet, even though both groups lost the same amount of total weight. This could be bad for long-term health.
