I think carbs were the bulk of the average diet in those days. Bread for breakfast whether toasted or just buttered to accompany the boiled egg or fried breakfast; sandwiches at mid day; potatoes at every evening meal (lots of them) and always a pastry based pudding.
Often another sandwich at supper time, or pikelets (crumpets) or even a bag of chips.
