I think its definately a 'patronise the customer with no intention of listening to or doing anything they have asked" sort of letter.

Well done with the big weight loss on the fat fast.
What did you eat? ive been thinking of doing it for a while as the weight loss boost would do me good but not too sure what Id eat.
