Is 4400 calories of a week's worth of chocolate unhealthy?

Do you really need to ask this? Of course it is. Noone should be eating that many calories in one day or they will become obese quite quickly and get all the diseases associated with obesity along with it. It wouldn't matter if you ate 4400 calories worth in brocolli, unless you're burning 4400 calories a day, you will gain weight and become unhealthy.
