Why Some People Think They Are 'Hardgainers' (Ectomorphs)
Self-described ectomorphs who claim they "eat 4,000 calories and can't gain weight" consistently under-report their food intake by 30–50% in metabolic chamber studies. In reality, they have high spontaneous NEAT (fidgeting, walking, pacing) and small appetites.
Why Some People Think They Have a 'Slow Metabolism' (Endomorphs)
Conversely, self-described endomorphs who claim to "gain weight on 1,200 calories" are almost universally suffering from tracking errors (uncounted cooking oils, dressings, weekend binge calories) and low daily step counts.
