assertion
Analysis v1
If you’re already skinny and lean, you can’t build muscle well unless you eat more.
Scientific Claim
Individuals with low body fat percentages (<15% for men, <25% for women) exhibit diminished capacity for muscle hypertrophy under caloric maintenance or deficit due to insufficient endogenous energy reserves.
Original Statement
“If you're already pretty lean, say under 15% body fat for men or 25% for women, your body may not have enough stored energy to reliably fuel muscle growth, which can leave you spinning your wheels.”
