&gt;Fat is very dense in calories, so if your goal is to reduce caloric intake, reducing the fat will go a long ways towards that goal.<p>This thinking empowers so much over-eating in today&#x27;s diet world. There&#x27;s a trope with the broken low-fat wisdom that when you buy low-fat foods, you&#x27;re almost always buying high-sugar high-salt foods (have to replace flavor somehow).<p>Even worse, upper intestinal lipids trigger a feeling of satiation, of fullness, through the gut–brain–liver axis.<p>If you deprive yourself of lipids, you deprive yourself of satiation -- eating a healthy mix of fats in your meals helps you feel more full and sated and eat overall less, and feel good about eating overall less.
