Frankly, that's scary, putting caffeine in you and then either cycling in traffic or driving to the gym. You know what exercise without food leads to? Disorientation. Because your blood sugar is too low to support your brain's requirements. I've hit a glucose level of 55 many times, so I know full well what it does to your brain, and it's not safe to be on the road.
Nope. That fat might be good for safe calorie restriction diets, but skipping food and exercising is going to lead to a blood sugar drop, and that is stupid dangerous.
