It's an exact science, more so than one might expect.
Beef dripping chips might be the better option. The problem with the sugar in the crumble is that it will have a high glycaemic index value, causing your blood sugar to rise quickly and possibly spike - leading to a spike in insulin, resulting a short time later with low blood sugar and a stop for calories.

The theory is the fat will slow down the absorption of the sugars and carbs, keeping your blood sugar more stable.
