I will follow your quantity calories in/out up to a point, then i will say quality will override. You cant take a race car (or race horse) to the track on poor quality fuel, because poor combustion will clog up its filter and it wont run.

The filter being the human liver. That is where weight loss happens, as fats are turned into sugar and vice versa. You dont want them recycling in there forever. I think thats why fat people get nonalcoholic fatty liver. Hey i could live on cupcakes, but my liver cant anymore. Lately all my effort goes into not upsetting it! So i try to give it "single" foods - oranges, potatoes - that it doesnt have to figure out wtf it is.

Lets see how this mind trick works for me!
