my food for today

I decided to start a new diet today and noticed I'm sick every Wednesday it seems. I am going to have local toast and a shake for breakfast then a bar for lunch and a dinner of meat and starch and veggies for dinner. today I'm going to throw out the super moist chicken and stuffing and veggies thing I made and try a healthy choice dinner. but I'm dumping bad on something and I don't know what cause I'm eating everything I normally eat

I am pretty new to this only having my RNY on Dec3. Do you mind if I ask why the toast for breakfast, the bar later and then a starch, veggies ect for dinner? Lots of carbs there without even adding the processed food " Healthy Choice dinner" which has tons of sodium. Maybe excess carbs are making you dump. Is that possible?
