While exercise will have some impact the vast majority of weight is controlled by what you eat not what you do. Also calories are not burnt in a simple one to one equation. Different types of calories are processed definitely in the body. Sugar turns to fat, but the same amount of calories in bacon, or carrots, or bread, are all different, and your body will use them differently. The less processed a food is, the harder it is for your body to extract those calories, so measuring calories from what it says on yh packet is not the best guide.
Sorry, rambling.
Tl;Dr - Exercise for fitness, eat for fitness.
The music performed by the band ranged from outstanding to utter pretentious twaddle. Imho the most interesting thing about The Doors was the 1991 film about the band. Val Kilmer play Morrison. The likeness was uncanny.
The impression you get is the guy went to excess and succeeded at being a dick. Shame really cos I genuinely like most of their tracks.
