That's correct, eat a non fatty meal and take your quick-acting insulin as normal then start testing 4 hours after eating (the previous bolus dose is all but exhausted at this point) then miss your next meal and insulin dose, in theory your bg should go up or down by no more than 1-2 mmol if your basal dose is correct.

Just one other thing, try and avoid stressful situations and exercise too.
