What sort of diet is it?
edit just googled it.
'Such a diet is characterized by a high protein content, low fat content and reduced carbohydrate content'
It's also low calorie, so the protein may be a high percentage, but not a high load.
But nothing if there that would specifically be related to diabetes, in fact reduced carbs are good, low fat isn't going to hurt, a high amount of protein could if you have existing kidney damage, but your doctor hopefully would be aware before putting you on the diet.
But it is always best to discuss it with the dietician or HCP beforehand, and they can give you a definitive answer for yourself.
