Weight (in grams) > 5 – 10% fat means ‘fatty liver’ or non-alcoholic fatty liver disease (NAFLD), which is a silent disease often associated with obesity and metabolic syndrome or metabolic derangement.

An overwhelmed liver cannot properly process fats, glucose, or balance hormones. When your liver cannot metabolize fats & glucose, your insulin sensitivity is reduced. The result is often metabolic slowing and fat storage.

Fatigue, unexpected weight loss or weight gain, pain or discomfort around your abdomen, darkening skin (acanthosis nigricans) and elevation in liver enzymes. These are the first signs of problems.

Weight gain - especially central obesity - promotes liver fat storage. MASLD (Metabolic Dysfunction-associated Steatotic Liver Disease) is common even in "lean" insulin resistant individuals.

Losing just 5%-10% of body weight dramatically decreases liver fat and inflammation. At ≥ 10%, individuals may even reverse early liver damage - including NASH (Nonalcoholic Steatohepatitis), before seeing any cirrhosis.
