The Claim

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) undergoing a 30% caloric restriction for 4 weeks, supervised resistance training performed five days per week significantly improves isokinetic muscle strength and endurance across multiple joint regions, including the knee, shoulder, and trunk, compared to no exercise, despite no change in skeletal muscle mass.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Adults with metabolic dysfunction-associated steatotic liver disease who reduce their calorie intake by 30% for four weeks and perform supervised resistance training five days per week experience increased muscle strength and endurance in the knee, shoulder, and trunk, without an increase in muscle mass, compared to those who do not exercise.

See the scientific wording

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) undergoing a 30% caloric restriction for 4 weeks, supervised resistance training performed five days per week significantly improves isokinetic muscle strength and endurance across multiple joint regions, including the knee, shoulder, and trunk, compared to no exercise, despite no change in skeletal muscle mass.

Why this might work

When muscles are repeatedly stressed during strength training, the nervous system learns to activate more muscle fibers at the same time and more efficiently. This allows the muscles to produce more force and work longer, even if they don't get bigger. The body does this by sending stronger and better-coordinated signals from the brain to the muscles, bypassing the need for new muscle tissue.

  1. Study: Independent and Combined Effects of Resistance Training and Whey Protein on Skeletal Muscle Mass and Function in Individuals with MASLD Under Caloric Restriction

    When people with fatty liver eat much less and do strength training five times a week, their muscles get stronger and can work longer—even if their muscles don’t get bigger. The study proved this happens in the arms, legs, and core.
