| You say that you are 'in remission' . I'm assuming that means that you are type 1 'on honeymoon'.
As others have said the real problem with Mcdonalds is the fat rather than the carbs and the fat can cause a problem by delaying delaying the carb increase until much later after your meal. Over time you may learn ways to manipulate your insulin injections to get over this. Nevertheless many people believe a high fat diet is not good for anyone and particularly for people with diabetes.
Having said that I've eaten at Mcdonalds a handful of times (in three years) and have not suffered any dire consequences as the majority of the time I try to eat very healthily.
One point, what you do with fibre in your calculations depends on where you live.
Jacobsam mentions that you should deduct fibre from the carb count. This is true if you live in the US (and I think Canada) but not in Europe where the fibre content has already been deducted from the carbs.
eg. A quarter pounder with cheese in the US is listed as having 40 gms of of carbs and 3 gms of fibre
In the UK it is listed as 36gms of carbs and 4 gms of fibre.
In the US you would deduct 3 gms making 37 gms carbs
In the UK you would leave it at 36gms carbs and not subtract the fibre.
(I expect the difference is due to rounding errors)  |
