I'm pretty sure, having seen that, that this is just a really elaborate troll. I stopped engaging after seeing this.

His chosen method of achieving caloric restriction is to get 70% of his nutrition from cream. The amount of cream isn't even defined; it's just "I have some amount of coffee a day and this one time I measured how much cream was in it". If for whatever reason one day Starbucks changes their coffee and he ends up having 8 instead of 5 the whole thing will change arbitrarily.

If this is real then the guy needs psychological help.
