In overweight, sedentary adults with moderate dyslipidemia, 8 months of resistance training three times per week with 8 exercises and 3 sets of 8–12 repetitions does not reduce visceral fat, liver fat, liver enzyme levels, or insulin resistance, but does increase lean body mass and strength.
See the scientific wording
In overweight, sedentary adults with moderate dyslipidemia, 8 months of resistance training involving 3 days per week of 8 exercises with 3 sets of 8–12 repetitions does not significantly reduce visceral fat, liver fat, alanine aminotransferase, or fasting insulin resistance (HOMA), despite increasing lean body mass and strength.

What the research says

Randomized Controlled TrialHuman2011
Lifting weights three times a week for 8 months helped people get stronger and build muscle, but didn’t shrink the dangerous fat around their organs or improve their blood sugar control. Only walking or jogging did that.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Lifting weights builds muscle and makes you stronger, but it does not burn enough energy to reduce fat stored in the liver or around organs. Without reducing this fat, the liver remains overloaded with lipids, which blocks insulin from working properly, so blood sugar stays high. Only activities that burn large amounts of energy, like jogging, can clear this fat and fix insulin resistance.

Mechanism
1 studyLifting weights builds muscle but doesn't burn enough calories to clear fat from the liver or around organs. That fat blocks insulin from working, so blood sugar stays high. Only activities like jogging burn enough energy to remove this fat and fix insulin resistance.

Resistance training stimulates muscle protein synthesis and increases lean body mass through mechanical tension and mTOR pathway activation
Resistance training does not elevate systemic energy expenditure sufficiently to trigger significant adipose tissue lipolysis or hepatic fatty acid oxidation
Persistent accumulation of diacylglycerol and ceramides in hepatocytes inhibits insulin receptor substrate-1 phosphorylation
Reduced hepatic insulin signaling maintains elevated gluconeogenesis and impairs glucose uptake, sustaining fasting hyperinsulinemia
Ectopic fat deposits in the liver and visceral cavity remain unchanged due to insufficient lipid mobilization and oxidation
Hepatocyte stress from lipid overload continues, maintaining elevated alanine aminotransferase release into circulation
