When lean men eat meals with more fat or protein instead of lots of carbs, they feel less hungry, fuller longer, and end up eating less food later.
Scientific Claim
In lean men, high-fat and high-protein meals are associated with reduced hunger and greater fullness compared to high-carbohydrate/low-protein meals, and are associated with lower subsequent energy intake at a buffet meal.
Original Statement
“In lean subjects, hunger was less and fullness greater following HF, HP, and AP compared with HC/LP meals, and energy intake was less following HF and HP compared with HC meals (P < 0.05).”
Evidence Quality Assessment
Claim Status
overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
Based on abstract only - full methodology not available to verify. The study design lacks confirmation of randomization or control, so causal language is unsupported. The observed differences are associations, not proven effects.

In lean men, eating meals high in fat or protein made them feel fuller and less hungry than eating meals high in carbs, and they ended up eating less food later — exactly what the claim says.
