Why Do Some Foods Keep You Fuller?
Feeling full after eating depends on several factors, including how much protein, fibre and healthy fat a meal contains. Foods that digest more slowly generally help keep hunger away for longer than highly processed foods that are low in these nutrients.
Drinking enough water and eating balanced meals also play an important role in supporting healthy appetite control.
