Can lifting weights and drinking protein shake help you keep muscle while dieting?
Independent and Combined Effects of Resistance Training and Whey Protein on Skeletal Muscle Mass and Function in Individuals with MASLD Under Caloric Restriction

People with fatty liver lost fat while dieting, and those who lifted weights kept their muscle strength — even without extra protein shakes. More protein didn’t help them get stronger.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Adding protein shakes to strength training doesn’t make people with fatty liver disease any stronger or more enduring than just doing the workouts alone — even when they’re eating less food.
People with fatty liver disease on a low-calorie diet don’t lose muscle if they eat at least 0.8 grams of protein per kilogram of body weight each day — eating more protein doesn’t help any more.
When people with fatty liver disease do strength training for a month while eating less, they get stronger not because their muscles grow bigger, but because their brain and nerves learn to use the muscles better.
When people with fatty liver disease eat a lot of protein and lift weights at the same time while eating very little, they don’t get any extra muscle benefits — the two things don’t work together like they usually do.
In individuals with elevated body fat stores, resistance training during a caloric deficit can sustain muscle hypertrophy while promoting net fat loss.
