I've been doing really well with my atkins(ish) diet for the past two days and even managed to lose 2lbs on my second day. Today I used a ketostix and it had started turning purple. Was really pleased and motivated.
But, it's DS's birthday today and everyone insisted I have a "tiny" bit of cake. Didn't want to upset DS so had a very, very small piece of the (chocolate sponge covered in choc icing) cake. Carbs were 29g per slice.
That's more than I'm supposed to have in an entire day
Have I totally blown it? will I have put 2lbs on now? Will I have to start all over again? feeling quite disapointed with myself.
