                                Scientific studies, particularly research on identical twins, have shown that the heritability of traits like satiety responsiveness can be as high as 60-70%. This strong genetic component confirms that some people naturally have a bigger appetite due to a complex interplay of biological factors, challenging the idea that appetite is purely a matter of willpower.
