> Reducing fat reduces caloric intake. Indeed, but people who want to "lose weight" actually don't care how heavy they are, they care how they look and want "to be slimmer" which is the actual result we're trying for while colloquially using the term "lose weight" to describe that effect. (this is of course a sweeping over-generalization where there are actually a number of other reasons, related to health, fatty liver etc...) With a goal of "BEING SLIMMER" we'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's another story). Since the goal is to drain fat cells, we're actually better served by keeping our bodies in the state where they are "emptying the fuel tanks (stored fat)" as opposed to "burning the cheap stuff (carbohydrates)" By reducing CARB intake we can keep the fat-cells open and draining. BUT in order to reduce carb intake, we have to replace it with a macronutrient which will induce satiety. Dietary fat is that macronutrient.
