&gt; Reducing fat reduces caloric intake.<p>Indeed, but people who want to &quot;lose weight&quot; actually don&#x27;t care how heavy they are, they care how they look and want &quot;to be slimmer&quot; which is the actual result we&#x27;re trying for while colloquially using the term &quot;lose weight&quot; to describe that effect.<p>(this is of course a sweeping over-generalization where there are actually a number of other reasons, related to health, fatty liver etc...)<p>With a goal of &quot;BEING SLIMMER&quot; we&#x27;re actually more interested in draining triglycerides from our fat cells so they shrink. (after that we can induce apoptosis and kill them off via freezing but that&#x27;s another story).<p>Since the goal is to drain fat cells, we&#x27;re actually better served by keeping our bodies in the state where they are &quot;emptying the fuel tanks (stored fat)&quot; as opposed to &quot;burning the cheap stuff (carbohydrates)&quot;<p>By reducing CARB intake we can keep the fat-cells open and draining. <i>BUT</i> in order to reduce carb intake, we have to replace it with a macronutrient which will induce satiety.<p>Dietary fat is that macronutrient.
